• Isolating test data in acceptance tests

  - by Matt Phillips

  I'm looking for guidance on how to keep my acceptance tests isolated. Right now the issue I'm having with being able to run the tests in parallel is the database records that are manipulated in the tests. I've written helpers that take care of doing inserts and deletes before tests are executed, to make sure the state is correct. But now I can't run them in parallel against the same database without uniquely generating the test data fields for each test. For example. Testing creating a row i'll delete everything where column A = foo and column B = bar Then I'll navigate through the UI in the test and create a record with column A = foo and column B = bar. Testing that a duplicate row is not allowed to be created. I'll insert a row with column A = foo and column B = bar and then use the UI to try and do the exact same thing. This will display an error message in the UI as expected. These tests work perfectly when ran separately and serially. But I can't run them at the same time for fear that one will create or delete a record the other is expecting. Any tips on how to structure them better so they can be run in parallel?

• Getting the relational table data into XML recursively

  - by Tom

  I have levels of tables (Level1, Level2, Level3, ...) For simplicity, we'll say I have 3 levels. The rows in the higher level tables are parents of lower level table rows. The relationship does not skip levels however. E.g. Row1Level1 is parent of Row3Level2, Row2Level2 is parent of Row4Level3. Level(n-1)'s parent is always be in Level(n). Given these tables with data, I need to come up with a recursive function that generates an XML file to represent the relationship and the data. E.g. <data> <level levelid = 1 rowid=1> <level levelid = 2 rowid=3 /> </level> <level levelid = 2 rowid=2> <level levelid = 3 rowid=4 /> </level> </data> I would like help with coming up with a pseudo-code for this setup. This is what I have so far: XElement GetXMLData(Table table, string identifier, XElement data) { XElement xmlData = data; if (table != null) { foreach (row in the table) { // Get subordinate table Table subordinateTable = GetSubordinateTable(table); // Get the XML Data for the children of current row xmlData += GetXMLData(subordinateTable, row.Identifier, xmlData); } } return xmlData; }

• Creating Parent-Child Relationships in SSRS

  - by Tim Murphy

  As I have been working on SQL Server Reporting Services reports the last couple of weeks I ran into a scenario where I needed to present a parent-child data layout.  It is rare that I have seen a report that was a simple tabular or matrix format and this report continued that trend.  I found that the processes for developing complex SSRS reports aren’t as commonly described as I would have thought.  Below I will layout the process that I went through to create a solution. I started with a List control which will contain the layout of the master (parent) information.  This allows for a main repeating report part.  The dataset for this report should include the data elements needed to be passed to the subreport as parameters.  As you can see the layout is simply text boxes that are bound to the dataset. The next step is to set a row group on the List row.  When the dialog appears select the field that you wish to group your report by.  A good example in this case would be the employee name or ID. Create a second report which becomes the subreport.  The example below has a matrix control.  Create the report as you would any parameter driven document by parameterizing the dataset. Add the subreport to the main report inside the row of the List control.  This can be accomplished by either dragging the report from the solution explorer or inserting a Subreport control and then setting the report name property. The last step is to set the parameters on the subreport.  In this case the subreport has EmpId and ReportYear as parameters.  While some of the documentation on this states that the dialog will automatically detect the child parameters, but this has not been my experience.  You must make sure that the names match exactly.  Tie the name of the parameter to either a field in the dataset or a parameter of the parent report. del.icio.us Tags: SQL Server Reporting Services,SSRS,SQL Server,Subreports

• AJAX driven "page complete" function? Am I doing it right?

  - by Julian H. Lam

  This one might get me slaughtered, since I'm pretty sure it's bad coding practice, so here goes: I have an AJAX driven site which loads both content and javascript in one go using Mootools' Request.HTML. Since I have initialization scripts that need to be run to finish "setting up" the template, I include those in a function called pageComplete(), on every page Visiting one page to another causes the previous pageComplete() function to no longer apply, since a new one is defined. The javascript function that loads pages dynamically calls pageComplete() blindly when the AJAX call is completed and is loaded onto the page: function loadPage(page, params) { // page is a string, params is a javascript object if (pageRequest && pageRequest.isRunning) pageRequest.cancel(); pageRequest = new Request.HTML({ url: '<?=APPLICATION_LINK?>' + page, evalScripts: true, onSuccess: function(tree, elements, html) { // Empty previous content and insert new content $('content').empty(); $('content').innerHTML = html; pageComplete(); pageRequest = null; } }).send('params='+JSON.encode(params)); } So yes, if pageComplete() is not defined in one the pages, the old pageComplete() is called, which could potentially be disastrous, but as of now, every single page has pageComplete() defined, even if it is empty. Good idea, bad idea?

• When is it better to offload work to the RDBMS rather than to do it in code?

  - by GeminiDomino

  Okay, I'll cop to it: I'm a better coder than I am at databases, and I'm wondering where thoughts on "best practices" lie on the subject of doing "simple" calculations in the SQL query vs. in the code, such as this MySQL example (I didn't write it, I just have to maintain it!) -- This returns the username, and the users age as of the last event. SELECT u.username as user, IF ((DAY(max(e.date)) - DAY(u.DOB)) &lt; 0 , TRUNCATE(((((YEAR(max(e.date))*12)+MONTH(max(e.date))) -((YEAR(u.DOB)*12)+MONTH(u.DOB)))-1)/12, 0), TRUNCATE((((YEAR(max(e.date))*12)+MONTH(max(e.date))) - ((YEAR(u.DOB)*12)+MONTH(u.DOB)))/12, 0)) AS age FROM users as u JOIN events as e ON u.id = e.uid ... Compared to doing the "heavy" lifting in code: Query: SELECT u.username, u.DOB as dob, e.event_date as edate FROM users as u JOIN events as e ON u.id = e.uid code: function ageAsOfDate($birth, $aod) { //expects dates in mysql Y-m-d format... list($by,$bm,$bd) = explode('-',$birth); list($ay,$am,$ad) = explode('-',$aod); //Insert Calculations here ... return $Dy; //Difference in years } echo "Hey! ". $row['user'] ." was ". ageAsOfDate($row['dob'], $row['edate']) . " when we last saw him."; I'm pretty sure in a simple case like this it wouldn't make much difference (other than the creeping feeling of horror when I have to make changes to queries like the first one), but I think it makes it clearer what I'm looking for. Thanks!

• When mapping the surface of a sphere with tiles, how might you deal with polar distortion?

  - by clweeks

  It's easy to deal with the way locations interact on a clean Cartesian grid. It's just vanilla math. And you can kind of ignore the geometry of the sphere's surface for a bunch of it if you want to just truncate the poles or something. But I keep coming up with ideas for games where the polar space matters. Geo-coded ARGs and global roguelikes and stuff. I want square(ish?) locations -- reasonably representable by square tiles of the same size across the globe, anyway. This has to be a solved problem, right? What are the solutions? ETA: At the equator -- and assuming that your square locations are reasonably small, it's close enough to true that you can get away with having one square in the rows north and south of the most equatorial row. And you could probably get away with that by just hand-waving the difference up to like 45-degrees or so. But eventually, you need to have fewer squares in a pole-ward circumferential row. If I reduce the length of the row by one and offset the squares by 1/2 then they're just like hexes and it's relatively easy to do the coding to keep track of the connections. But as you get pole-ward, it gets more and more extreme. Projecting the surface of the world onto the surface of a cube is tempting. But I figured there must be more elegant solutions already in use. If I did the cube thing (not dissecting it further through geodesy) Are there any pros and cons related to placing the pole at the center of a face or at the vertex of three sides?

• Slick 2d scrolling off screen

  - by Peter

  I have something scrolling in and out of the screen. Now when it goes off screen, I want it to scroll into the screen at another location. What I do is I grab the last pixels at the screens edge using g.copyArea and then g.drawImage on the edge of the screen. And then I do a g.translate to create room for the next row which is next render cycle. My problem is that I get a single pixel row, which is not copied onto the canvas. Where as I want each row to be added and then translated, so that the image that scrolled off screen is recreated on the other side of the screen. Here is my code, maybe there is a better way of doing this, open to any suggests, cause I'm totally stuck @Override public void render(GameContainer gc, Graphics g) throws SlickException { //g.setClip(0, 0, 300, gc.getHeight()); g.translate(0, y); g.drawImage(image,0,200); g.resetTransform(); //g.clearClip(); g.copyArea(rightImage, 0, gc.getHeight() - 1); g.drawImage(rightImage, 300, 0); g.translate(0, y); y=y+3; }

• How to capture a Header or Trailer Count Value in a Flat File and Assign to a Variable

  - by Compudicted

  Recently I had several questions concerning how to process files that carry a header and trailer in them. Typically those files are a product of data extract from non Microsoft products e.g. Oracle database encompassing various tables data where every row starts with an identifier. For example such a file data record could look like: HDR,INTF_01,OUT,TEST,3/9/2011 11:23 B1,121156789,DATA TEST DATA,2011-03-09 10:00:00,Y,TEST 18 10:00:44,2011-07-18 10:00:44,Y B2,TEST DATA,2011-03-18 10:00:44,Y B3,LEG 1 TEST DATA,TRAN TEST,N B4,LEG 2 TEST DATA,TRAN TEST,Y FTR,4,TEST END,3/9/2011 11:27 A developer is normally able to break the records using a Conditional Split Transformation component by employing an expression similar to Output1 -- SUBSTRING(Output1,1,2) == "B1" and so on, but often a verification is required after this step to check if the number of data records read corresponds to the number specified in the trailer record of the file. This portion sometimes stumbles some people so I decided to share what I came up with. As an aside, I want to mention that the approach I use is slightly more portable than some others I saw because I use a separate DFT that can be copied and pasted into a new SSIS package designer surface or re-used within the same package again and it can survive several trailer/footer records (!). See how a ready DFT can look: The first step is to create a Flat File Connection Manager and make sure you get the row split into columns like this: After you are done with the Flat File connection, move onto adding an aggregate which is in use to simply assign a value to a variable (here the aggregate is used to handle the possibility of multiple footers/headers): The next step is adding a Script Transformation as destination that requires very little coding. First, some variable setup: and finally the code: As you can see it is important to place your code into the appropriate routine in the script, otherwise the end result may not be as expected. As the last step you would use the regular Script Component to compare the variable value obtained from the DFT above to a package variable value obtained say via a Row Count component to determine if the file being processed has the right number of rows.

• Google Analytics Visitors drop-off for certain region of site only

  - by crmpicco

  I have an issue with the tracking on my site where I have seen a dramatic drop off of visitors to the site from a certain region. I have four regions on my site at the moment, these are UK, EU, US and RoW (Rest of the World). The UK, EU and US regions are unaffected, only the RoW region suffers this drop-off. I have included a screen shot below from my GA account, which shows this effect. My GA code, which is included on every page on the site is below. I have changed the UA account number intentionally for this example. There have been no changes made to the GA account or the tracking code in a live environment for some considerable time, but for some reason I am seeing the drop-off for this region only. In the code below I am not tracking page views on certain pages as I have event tracking setup for these pages. <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-18721873-5']); _gaq.push(['_setCookiePath', '/row/']); if ( typeof(p_page) != 'undefined') { // do nothing if user is on above pages // N.B. there are a series of conditions in this if statement checking that we are not on a particular page } else { _gaq.push(['_trackPageview']); } </script>

• 15 Puzzle Shuffle Method Issues

  - by Codemiester

  I am making a 15 puzzle game in C# that allows the user to enter a custom row and column value up to a maximum of a 10 x 10 puzzle. Because of this I am having problems with the shuffle method. I want to make it so the puzzle is always solvable. By first creating a winning puzzle then shuffling the empty space. The problem is it is too inefficient to call every click event each time. I need a way to invoke the click event of a button adjacent to the empty space but not diagonal. I also use an invisible static button for the empty spot. The PuzzlePiece class inherits from Button. I am not too sure how to do this. I would appreciate any help. Thanks here is what I have: private void shuffleBoard() { //5 is just for test purposes for (int i = 0; i < 5; i++) { foreach (Control item in this.Controls) { if (item is PuzzlePiece) { ((PuzzlePiece)item).PerformClick(); } } } } void PuzzlePiece_Click(object sender, EventArgs e) { PuzzlePiece piece = (PuzzlePiece)sender; if (piece.Right == puzzleForm.emptyPiece.Left && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Left == puzzleForm.emptyPiece.Right && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Top == puzzleForm.emptyPiece.Bottom && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } else if (piece.Bottom == puzzleForm.emptyPiece.Top && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } }

• Problem with a* implementation in pygame

  - by piyush3dxyz

  Yesterday i decide to make RTS game in pygame(pygame is best).I figured out many components of RTS game like unit selecting,health,resources but only 1 thing i still not understand.. which is a* pathfinding in pygame... I also done little bit of research on wiki,articles and papers...but still cant figure out problem.... function A*(start,goal) closedset := the empty set // The set of nodes already evaluated. openset := {start} // The set of tentative nodes to be evaluated, initially containing the start node came_from := the empty map // The map of navigated nodes. g_score[start] := 0 // Cost from start along best known path. // Estimated total cost from start to goal through y. f_score[start] := g_score[start] + heuristic_cost_estimate(start, goal) while openset is not empty current := the node in openset having the lowest f_score[] value if current = goal return reconstruct_path(came_from, goal) remove current from openset add current to closedset for each neighbor in neighbor_nodes(current) if neighbor in closedset continue tentative_g_score := g_score[current] + dist_between(current,neighbor) if neighbor not in openset or tentative_g_score <= g_score[neighbor] came_from[neighbor] := current g_score[neighbor] := tentative_g_score f_score[neighbor] := g_score[neighbor] + heuristic_cost_estimate(neighbor, goal) if neighbor not in openset add neighbor to openset return failure here is the pseudocode for wiki a* implementation......

• Layout Columns - Equal Height

  - by Kyle

  I remember first starting out using tables for layouts and learned that I should not be doing that. I am working on a new site and can not seem to do equal height columns without using tables. Here is an example of the attempt with div tags. <div class="row"> <div class="column">column1</div> <div class="column">column2</div> <div class="column">column3</div> <div style="clear:both"></div> </div> Now what I tried with that was doing making columns float left and setting their widths to 33% which works fine, I use the clear:both div so that the row would be the size of the biggest column, but the columns will be different sizes based on how much content they have. I have found many fixes which mostly involve css hacks and just making it look like its right but that's not what I want. I thought of just doing it in javascript but then it would look different for those who choose to disable their javascript. The only true way of doing it that I can think of is using tables since the cells all have equal heights in the same row. But I know its bad to use tables. After searching forever I than came across this: http://intangiblestyle.com/lab/equal-height-columns-with-css/ What it seems to do is exactly the same as tables since its just setting its display exactly like tables. Would using that be just as bad as using tables? I honestly can't find anything else that I could do. edit @Su' I have looked into "faux columns" and do not think that is what I want. I think I would be able to implement better designs for my site using the display:table method. I posted this question because I just wasn't sure if I should since I have always heard its bad using tables in website layouts.

• Smooth drag scrolling of an Isometric map - Html5

  - by user881920

  I have implemented a basic Isometric tile engine that can be explored by dragging the map with the mouse. Please see the fiddle below and drag away: http://jsfiddle.net/kHydg/14/ The code broken down is (CoffeeScript): The draw function draw = -> requestAnimFrame draw canvas.width = canvas.width for row in [0..width] for col in [0..height] xpos = (row - col) * tileHeight + width xpos += (canvas.width / 2) - (tileWidth / 2) + scrollPosition.x ypos = (row + col) * (tileHeight / 2) + height + scrollPosition.y context.drawImage(defaultTile, Math.round(xpos), Math.round(ypos), tileWidth, tileHeight) Mouse drag-scrolling control scrollPosition = x: 0 y: 0 dragHelper = active: false x: 0 y: 0 window.addEventListener 'mousedown', (e) => handleMouseDown(e) , false window.addEventListener 'mousemove', (e) => handleDrag(e) , false window.addEventListener 'mouseup', (e) => handleMouseUp(e) , false handleDrag = (e) => e.preventDefault() if dragHelper.active x = e.clientX y = e.clientY scrollPosition.x -= Math.round((dragHelper.x - x) / 28) scrollPosition.y -= Math.round((dragHelper.y - y) / 28) handleMouseUp = (e) => e.preventDefault() dragHelper.active = false handleMouseDown = (e) => e.preventDefault() x = e.clientX y = e.clientY dragHelper.active = true dragHelper.x = x dragHelper.y = y The Problem As you can see from the fiddle the dragging action is ok but not perfect. How would I change the code to make the dragging action more smooth? What I would like is the point of the map you click on to stay under the mouse point whilst you drag; the same as they have done here: http://craftyjs.com/demos/isometric/

• MultiSelectChoice: How to get underlying values selected

  - by Vijay Mohan

  Let's say you include a multiselectchoice component in your jspx/jsff page, which has <f;selectItem> or <af:forEach> binded to a VO iterator to populate the multiselectchoice and the value property of which is binded to a List attribute binding.When the user selects some items in that choice List then u want the actual values to be posted.You can check the valuepassthrough flag to true , but many a times it doesn't help and you end up getting the indexes of multiselect values.Here is a way to get the actual values..Lets say in the bean u have a utility method to achieve this as follows..You can associate a valueChangeListener for the multiselectchoice as follows..public void onValueChangeOfLOV(ValueChangeEvent valueChangeEvent) { //get array of indexes of selected items in master list List valueIndexes = (List)valueChangeEvent.getNewValue(); String concatCodes = returnSelectmanyChoiceValues(valueIndexes,"YourIterator", "YourAttribute"); } public String returnSelectmanyChoiceValues(List valueIndexes,String iterName, String idAttrName){ DCBindingContainer dc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry(); DCIteratorBinding iter = dc.findIteratorBinding(iterName); ViewObject vo = iter.getViewObject(); String codes = ""; for(Object index : valueIndexes){ String iIndex = (String)index; Row row = vo.getRowAtRangeIndex(Integer.parseInt(iIndex)); codes = codes +(String)row.getAttribute(idAttrName)+","; } //remove last "," if(codes.endsWith(",")) codes = codes.substring(0,codes.lastIndexOf(",")); return codes; }This will return u a comma separated values of the selected items. if you want thenYou can store it in a List.

• Trouble with Collada bones

  - by KyleT

  I have a Collada file with a rigged mesh. I've read the node tags in the library_visual_scenes tag and extracted the matrix for each node and stored everything in a hierarchical bone structure. My Matrix container is "row major", so I'd store the first float of a matrix tag in the 1st row, 1st column, the second in the 1st row, 2nd column, etc. From what I gather this is the Bind Pose Matrix. After that I went through the tag and extracted the float array in the source tag of the skin tag of the controller for the mesh. I stored each matrix from this float array in their corresponding Bone as the Inverse Bind Matrix. I also extracted the bind-shape-matrix and stored it. Now I'd like to draw the skeleton with OpenGL to see if everything is working correctly before I go about skinning. I iterate once over my bones and multiply a bone's Bind Pose Matrix by it's parents and store that. After that I iterate again over the bones and multiply the result of the previous matrix multiplication by the Inverse Bind Matrix and then by the Bind Shape Matrix. The results look something like this: [0.2, 9.2, 5.8, 1.2 ] [4.6, -3.3, -0.2, -0.1 ] [-1.8, 0.2, -4.2, -3.9 ] [0, 0, 0, 1 ] I've had to go to various sources to get the little understanding of Collada I have and books about 3d transform matricies can get pretty intense. I've hit a brick wall and if you could please read through this and see if there is something I'm doing wrong, and how I'd go about getting an X,Y,Z to draw a point for each of these joints once I've calculated the final transform, I'd really appreciate it.

• Matrices: Arrays or separate member variables?

  - by bjz

  I'm teaching myself 3D maths and in the process building my own rudimentary engine (of sorts). I was wondering what would be the best way to structure my matrix class. There are a few options: Separate member variables: struct Mat4 { float m11, m12, m13, m14, m21, m22, m23, m24, m31, m32, m33, m34, m41, m42, m43, m44; // methods } A multi-dimensional array: struct Mat4 { float[4][4] m; // methods } An array of vectors struct Mat4 { Vec4[4] m; // methods } I'm guessing there would be positives and negatives to each. From 3D Math Primer for Graphics and Game Development, 2nd Edition p.155: Matrices use 1-based indices, so the first row and column are numbered 1. For example, a12 (read “a one two,” not “a twelve”) is the element in the first row, second column. Notice that this is different from programming languages such as C++ and Java, which use 0-based array indices. A matrix does not have a column 0 or row 0. This difference in indexing can cause some confusion if matrices are stored using an actual array data type. For this reason, it’s common for classes that store small, fixed size matrices of the type used for geometric purposes to give each element its own named member variable, such as float a11, instead of using the language’s native array support with something like float elem[3][3]. So that's one vote for method one. Is this really the accepted way to do things? It seems rather unwieldy if the only benefit would be sticking with the conventional math notation.

• Command Query Separation

  - by Liam McLennan

  Command query separation is a strategy, proposed by Bertrand Meyer, that each of an object’s methods should be either a command or a query. A command is an operation that changes the state of a system, and a query is an operation that returns a value. This is not the same thing as CQRS, hence why I think that CQRS is poorly named. An Example of Command Query Separation Consider a system that models books and shelves. There is a rule that a shelf may not be removed if it holds any books. One way to implement the removal is to write a method Shelf.Remove() that internally checks to make sure that the shelf is empty before removing it. If the shelf is not empty then it is not removed and an error is returned. To implement this feature following the principle of command query separation would require two methods, one to query the shelf and determine if it is empty and a second method to remove the shelf. Separating the query from the command makes the shelf class simpler to use because the state change is clear and explicit.

  This is the first time i'm doing this and have been doing some research on it. I have a page that selects some info from a database and displays it with a link to a second page that uses the result to query the database, something like this: $sel=mysql_query("select id, title from thetable "); while($row=mysql_fetch_array($sel)) { $id=$row['id']; $title=$row['title']; echo "<a href='more.php?id=$id'>$title</a>"; } The issue is, in the more.php page, instead of more.php?id=5 to show in the address bar, I want something like more/title Secondly, as it obtains in most sites, I want the link on the referring page to show this friendly url on mouse hover not the more.php?id=5 And I notice in most sites some words like 'a', 'and', 'the' etc are usually removed from the url title(even if there originally), moreover how does one handle the situation where more than one record have the same title. How does one go about achieving this url rewrite with htaccess or whatever method is used. Thanks.

• How can I guarantee a solvable Fifteen Puzzle shuffle?

  - by Codemiester

  I am making a 15 Puzzle game in C# that allows the user to enter a custom row and column value up to a maximum of a 10 x 10 puzzle. I am having problems with the shuffle method. I want to make it so the puzzle is always solvable by first creating a winning puzzle then shuffling the empty space. The problem is it is too inefficient to call every click event each time. I need a way to invoke the click event of a button adjacent to the empty space but not diagonal. I also use an invisible static button for the empty spot. The PuzzlePiece class inherits from Button. I am not too sure how to do this. Here is what I have: private void shuffleBoard() { //5 is just for test purposes for (int i = 0; i < 5; i++) { foreach (Control item in this.Controls) { if (item is PuzzlePiece) { ((PuzzlePiece)item).PerformClick(); } } } } void PuzzlePiece_Click(object sender, EventArgs e) { PuzzlePiece piece = (PuzzlePiece)sender; if (piece.Right == puzzleForm.emptyPiece.Left && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Left == puzzleForm.emptyPiece.Right && piece.Top == puzzleForm.emptyPiece.Top) { movePiece(piece); } else if (piece.Top == puzzleForm.emptyPiece.Bottom && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } else if (piece.Bottom == puzzleForm.emptyPiece.Top && piece.Left == puzzleForm.emptyPiece.Left) { movePiece(piece); } }

• Focusable EditText inside ListView

  - by Joe

  I've spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it's generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector. I've tried many possibilities, and have so far had no luck. layout: <ListView android:id="@android:id/list" android:layout_height="fill_parent" android:layout_width="fill_parent" /> Header view: EditText view = new EditText(this); listView.addHeaderView(view, null, true); Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected; but when getting to the header row, it is also displayed with the selector, and no way to focus into the EditText using the jogball. Note: tapping on the EditText will focus it at that point, however that relies on a touchscreen, which should not be a requirement. ListView apparently has two modes in this regard: 1. setItemsCanFocus(true): selector is never displayed, but the EditText can get focus when using the arrows. Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience. 2. setItemsCanFocus(false): selector is always drawn in non-touch-mode, and EditText can never get focus -- even if you tap on it. To make matters worse, calling editTextView.requestFocus() returns true, but in fact does not give the EditText focus. What I'm envisioning is basically a hybrid of 1 & 2, where rather than the list setting if all items are focusable or not, I want to set focusability for a single item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children. Any takers?
