  • How to customize android analog clock widget through configuration screen

    - by michJ
    I'm trying to develop my own analog clock widget on the home screen. It's based on the stock ICS analog clock widget, but when added to the homescreen, my widget opens a configuration screen first. On this screen you can choose the color you want the clock to be (through a colorpicker dialog). You also see a preview of the clock in the chosen color on this screen. (See picture). My problem is changing the color of the widget on the home screen to the chosen color (when you hit the apply button). I have three .png files that I use for the dial, hour hand and minute hand. I color them using this code in my widgetconfig class: Drawable dial = getResources().getDrawable(R.drawable.clockbackground); dial.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //hour Drawable hour = getResources().getDrawable(R.drawable.hourhand); hour.setColorFilter(color, PorterDuff.Mode.MULTIPLY); //minute Drawable min = getResources().getDrawable(R.drawable.minutehand); min.setColorFilter(color, PorterDuff.Mode.MULTIPLY); // clock AnalogClock clockpreview = (AnalogClock) findViewById(R.id.ACconfig); clockpreview.setBackgroundDrawable(dial); This works fine because I can find the AnalogClock since it's in the layout xml file of the configuration screen, which I set in the OnCreate() through setContentView(). The problem is that for the clock widget on my screen I have to use RemoteViews. So I tried setting the new background of the clock widget through RemoteViews. But RemoteViews seems too limited to do this. I need something like setTextViewText() but then for the background of my analog clock widget, like for example: RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.clockwidget); views.setAnalogClockBackgroundDrawable(dial); The clock widget background seems sort of unchangeable. How can I recolor my clockwidget on homescreen in widgetconfig class? There must be a way because it seems so easy to do at first... My project consists of the widget config class and clockwidget class, widgetconfig.xml, clockwidget.xml, and widget_info.xml (for appwidgetprovider).

  • Applet in different directory than .html page

    - by Jorge Matos
    Hello all, I'm trying to use a different directory to contain the applets and other directory with .html pages. Both are in the same level, that is, none is a sub-directory of the other. For that I was trying to use the parameter codebase, however, no matter what I put in codebase value (relative, absolute path) I always get a class not found error. I googled and found some people with the same problem, but no answers:( Does anybody knows how to accomplish this? I'm using JRE 1.6_20. Cheers, Jorge

  • Computing unique index for every poker starting hand

    - by Aly
    As there are 52 cards in a deck we know there are 52 choose 2 = 1326 distinct matchups, however in preflop poker this can be bucketed into 169 different hands such as AK offsuit and AK suited as whether it is A hearts K hearts or A spade K spades it makes no difference preflop. My question is, is there a nice mathematical property in which I can uniquely index each of these 169 hands (from 0 to 168 preferably). I am trying to create a look up table as a double[][] = new double [169][169] but have no way of changing a hand representation such as AKs (an Ace and a King of the same suit) to a unique index in this array.

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

  • Space-based architecture?

    - by rcampbell
    One chapter in Pragmatic Programmer recommends looking at a blackboard/space-based architecture + a rules engine as a more flexible alternative to a traditional workflow system. The project I'm working on currently uses a workflow engine, but I'd like to evaluate alternatives. I really feel like a SBA would be a better solution to our business problems, but I'm worried about a total lack of community support/user base/venders/options. JavaSpaces is dead, and the JINI spin-off Apache River seems to be on life support. SemiSpace looks perfect, but it's a one-man show. The only viable solution seems to be GigaSpaces. I'd like to hear your thoughts on space based architecture and any experiences you've had with real world implementations.

But when the pages renders the value of the email field is exactly as it was entered originally. Is there a way of clearing this field once and event has triggered? Cheers Dave

  • With the introduction of the HTML5 <canvas> element, could Swing be implemented in GWT?

    - by knorv
    With the introduction of the HTML5 <canvas> element, could Swing theoretically be implemented in Google Web Toolkit (GWT) by using the <canvas> tag for drawing? I'm aware of efforts to port source code from using Swing calls to GWT calls, but what I'm after is a pure behind the scenes port where a Swing application would compile under GWT without any source code modifications. Is that theoretically possible? Why? Why not?

  • VARCHAR does not work as expected in Apache Derby

    - by Tom Brito
    I'm having this same problem: How can I truncate a VARCHAR to the table field length AUTOMATICALLY in Derby using SQL? To be specific: CREATE TABLE A ( B VARCHAR(2) ); INSERT INTO A B VALUES ('1234'); would throw a SQLException: A truncation error was encountered trying to shrink VARCHAR '123' to length 2. that is already answered: No. You should chop it off after checking the meta-data. Or if you don't wanna check the meta-data everytime, then you must keep both your code and database in sync. But thats not a big deal, its a usual practice in validators. but my doubt is: isn't VARCHAR suppose to variate its size to fit the data? What's wrong with apache derby's VARCHAR?

  • Swingworker producing duplicate output/output out of order?

    - by Stefan Kendall
    What is the proper way to guarantee delivery when using a SwingWorker? I'm trying to route data from an InputStream to a JTextArea, and I'm running my SwingWorker with the execute method. I think I'm following the example here, but I'm getting out of order results, duplicates, and general nonsense. Here is my non-working SwingWorker: class InputStreamOutputWorker extends SwingWorker<List<String>,String> { private InputStream is; private JTextArea output; public InputStreamOutputWorker(InputStream is, JTextArea output) { this.is = is; this.output = output; } @Override protected List<String> doInBackground() throws Exception { byte[] data = new byte[4 * 1024]; int len = 0; while ((len = is.read(data)) > 0) { String line = new String(data).trim(); publish(line); } return null; } @Override protected void process( List<String> chunks ) { for( String s : chunks ) { output.append(s + "\n"); } } }

  • Accessing the feed/entry/id field of an ATOM 1.0 feed with the ROME library

    - by PartlyCloudy
    Hi, I feel a bit stupid asking this question, but I don't know how I can access the ID field of an entry when using ROME to parse an Atom feed. ROME provides it's own meta level of feeds/items, i.e. SyndFeed and SyndEntry. Being an abstraction over RSS and ATOM they only contain elements both formats support. Thus, there is no method to get an ID of an entry. There also exist low level packages for the distinct formats, and the Atom package contains com.sun.syndication.feed.atom.Entry, which provides getId(). However, I don't know how can I convert my SyndEntry into an Entry. I have not found a way to convert it. The (outdated) tutorials show a conversion, but that's only for output though. So how can I easily access the ID field? Thanks in advance.

  • Computation geometry: find where's the triangle after rotation, tranlastion or reflection in a mirro

    - by newba
    Hi, I have a small contest problem in which is given a set of points, in 2D, that form a triangle. This triangle may be subject to an arbitrary rotation, may be subject to an arbitrary translation (both in the 2D plane) and may be subject to a reflection on a mirror, but its dimensions were kept unchanged. Then, they give me a set of points in the plane, and I have to find 3 points that form my triangle after one or more of those geometric operations. Example: 5 15 8 5 20 10 6 5 17 5 20 20 5 10 5 15 20 15 10 I bet that have to apply some known algorithm, but I don't know which. The most common are: convex hull, sweep plane, triangulation, etc. Can someone give a tip? I don't need the code, only a push, please!

  • Issue with multipart/form-data

    - by kbrin80
    I am not able to get values from both files and text input in a servlet when my form includes multipart/form-data. I am using the apache.commons.fileuploads for help with the uploads. Any suggestions. Also in the code below there are some things that I feel should be more efficient. Is there a better way to store these multiple files in a db. public void performTask(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) { boolean promo = false; Database db = new Database(); Homepage hp = db.getHomePageContents(); String part = ParamUtils.getStringParameter(request, "part", ""); if(part.equals("verbage")) { String txtcontent = (String)request.getParameter("txtcontent"); String promoheader = (String)request.getParameter("promoheader"); String promosubheader = (String)request.getParameter("promosubheader"); hp.setBodyText(txtcontent); hp.setPromoHeader(promoheader); hp.setPromoSubHeader(promosubheader); System.err.println(txtcontent); } else { boolean isMultipart = ServletFileUpload.isMultipartContent(request); if (!isMultipart) { } else { FileItemFactory factory = new DiskFileItemFactory(); ServletFileUpload upload = new ServletFileUpload(factory); List items = null; try { items = upload.parseRequest(request); //System.err.print(items); } catch (FileUploadException e) { e.printStackTrace(); } Iterator itr = items.iterator(); while (itr.hasNext()) { FileItem item = (FileItem) itr.next(); if(item.getFieldName().equals("mainimg1")) { if(item.getName() !="") hp.setMainImg1(item.getName()); } if(item.getFieldName().equals("mainimg2")) { if(item.getName() !="") hp.setMainImg2(item.getName()); } if(item.getFieldName().equals("mainimg3")) { if(item.getName() !="") hp.setMainImg3(item.getName()); } if(item.getFieldName().equals("promoimg1")) { promo = true; if(item.getName() !="") { hp.setPromoImg1(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg1.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } if(item.getFieldName().equals("promoimg2")) { if(item.getName() !="") { hp.setPromoImg2(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg2.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } if(item.getFieldName().equals("promoimg3")) { if(item.getName() !="") { hp.setPromoImg3(item.getName()); try { File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/promoImg3.jpg"); item.write(savedFile); //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } System.err.println("FNAME =" + item.getFieldName() + " : " + item.getName()); if (item.isFormField()) { } else { try { if(!promo) { String itemName = item.getName(); File savedFile = new File("/Library/resin-4.0.1/webapps/ROOT/images/"+itemName); item.write(savedFile); } //System.err.print(items); } catch (Exception e) { System.err.println(e.getMessage()); } } } } } db.updateHomePageContent(hp);

  • how can i unmarshall in jaxb and enjoy the schema validation without using an explicit schema file

    - by ekeren
    I am using jaxb for my application configurations I feel like I am doing something really crooked and I am looking for a way to not need an actual file or this transaction. As you can see in code I: 1.create a schema into a file from my JaxbContext (from my class annotation actually) 2.set this schema file in order to allow true validation when I unmarshal JAXBContext context = JAXBContext.newInstance(clazz); Schema mySchema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile); jaxbContext.generateSchema(new MySchemaOutputResolver()); // ultimately creates schemaFile Unmarshaller u = m_context.createUnmarshaller(); u.setSchema(mySchema); u.unmarshal(...); do any of you know how I can validate jaxb without needing to create a schema file that sits in my computer? Do I need to create a schema for validation, it looks redundant when I get it by JaxbContect.generateSchema ? How do you do this?

  • Prevent SQL injection from form-generated SQL.

    - by Markos Fragkakis
    Hi all, I have a search table where user will be able to filter results with a filter of the type: Field [Name], Value [John], Remove Rule Field [Surname], Value [Blake], Remove Rule Field [Has Children], Value [Yes], Remove Rule Add Rule So the user will be able to set an arbitrary set of filters, which will result essentially in a completely dynamic WHERE clause. In the future I will also have to implement more complicated logical expressions, like Where (name=John OR name=Nick) AND (surname=Blake OR surname=Bourne), Of all 10 fields the user may or may not filter by, I don't know how many and which filters the user will set. So, I cannot use a prepared statement (which assumes that at least we know the fields in the WHERE clause). This is why prepared statements are unfortunately out of the question, I have to do it with plain old, generated SQL. What measures can I take to protect the application from SQL Injection (REGEX-wise or any other way)?

  • static void classes

    - by ivor
    Hello, I'm tidying up some of my code with the correct scope on some methods and attributes (I have two classes and at the moment I have a number which I just declared as public to get working, but I feel I should look into this and make private where possible, for better practice) When working in eclipse it's suggested on one method, when i change it private from public, that I can fix it by dropping off the scope so the method just says "static void" instead of public/private static void. Is this a better scenario to have nothing, rather than private or public - or is the default scope equivelant to public anyway ? Thanks

  • Essence of BiMap in Google collections

    - by littleEinstein
    I am still quite puzzled at the BiMap in Google collections/Guava. It was claimed that The two bimaps are backed by the same data; any changes to one will appear in the other. I browsed through the source code, and I found the use of delegate in ForwardingMap. But in any actually subclass of StandardBiMap, I do see the data are put into both the forward and reverse map. So what is the essence, and why it claims to have saved space by keeping only one copy of the data? Is it just the actual objects are one set, but two distinct sets of references to these objects are still needed, one set maintained in forward map, and the other in reverse map? private V putInBothMaps(K key, V value, boolean force) { boolean containedKey = containsKey(key); if (containedKey && Objects.equal(value, get(key))) { return value; } if (force) { inverse().remove(value); } else if (containsValue(value)) { throw new IllegalArgumentException( "value already present: " + value); } V oldValue = super.put(key, value); updateInverseMap(key, containedKey, oldValue, value); return oldValue; }

  • Application lifecycle and onCreate method in the the android sdk

    - by Leif Andersen
    I slapped together a simple test application that has a button, and makes a noise when the user clicks on it. Here are it's method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.easy); b.setOnClickListener(this); } public void onClick(View v) { MediaPlayer mp = MediaPlayer.create(this, R.raw.easy); mp.start(); while(true) { if (!mp.isPlaying()) { mp.release(); break; } } } My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method. Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later. :) Thank you.
