  • Trying to populate ListView in Android using objects from Parse

    - by mrwienerdog
    I am pretty darned new to android, and VERY new to Parse. I have created a class, StudentInformation, that includes columns for name, address, phone, etc. I would like to create a listview that contains the names of all students added to the class. How do I do this? I have got it to the point that I can Toast out the objectIDs of all of my entries, but can't figure out how to extract and add just the names to the ListView. Here is a snippet of the code: //Set up the listview studentListView = (ListView)findViewById(R.id.listViewStudents); //Create and populate an ArrayList of objects from parse ParseQuery query = new ParseQuery("StudentInformation"); final ArrayList<Object> studentList = new ArrayList<Object>(); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for(int i = 0;i < objects.size(); i++){ objects.get(i); studentList.add("name".toString()); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } }); //studentList.addAll(Arrays.asList(students)); listAdapter = new ArrayAdapter<Object>(this,android.R.layout.simple_list_item_1,studentList); studentListView.setAdapter(listAdapter); } I have left the toast in where I toatst out the objectIDs in the public void done.... method. Any help would be, as always, greatly appreciated. Should be mentioned (possibly), no errors are thrown, the listview just never gets populated after the toast disappears. Don't know if this will help anyone, but I took a bit from both posts below, and came up with this: //Set up the listview studentList = new ArrayList<String>(); //Create and populate an ArrayList of objects from parse listAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1); studentListView = (ListView)findViewById(R.id.listViewStudents); studentListView.setAdapter(listAdapter); final ParseQuery query = new ParseQuery("StudentInformation"); query.findInBackground(new FindCallback() { public void done(List<ParseObject> objects, ParseException e) { if (e == null) { //Toast.makeText(getApplicationContext(), objects.toString(), Toast.LENGTH_LONG).show(); for (int i = 0; i < objects.size(); i++) { Object object = objects.get(i); String name = ((ParseObject) object).getString("name").toString(); listAdapter.add(name); } } else { Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_LONG).show(); } } });

  • How to extract Twitter username from Search API via PHP

    - by Alexia
    The Twitter Search api returns results in ATOM/XML format which look like this: <author> <name>username (Friendly Name)</name> <uri>http://twitter.com/username</uri> </author> In my PHP I can get the name field as a variable, so it would look like this: $names = "username (Friendly Name)" But I want to use PHP to extract them as seperate variables, like this: $username = "username" $friendlyName = "Friendly Name" (without parantheses) TIA!

  • What is a python equivalent of PHP's var_dump()

    - by Zoredache
    When debugging in PHP I frequently find it useful to simply stick a var_dump($foo, $bar, ...) in my code to show me the the what a variable is, what is value is, and the same for anything that it contains. What is a good python equivalent for this? I have seen several things in my Google searching that are somewhat equivalent, but nothing that is the same or better.

  • Software Engineer, Developer, Programmer - Just a name?

    - by user51229
    I look at ads and the jobs seem to overlap. A lot of software engineer jobs even say CS or related degree so it doesn't seem like a degree in CS = software engineer. It seems like a programmer or developer with experience can transition to the role or become an "engineer". Or is the engineer just the same job with a fancy name... Is there really a difference or is it just HR throwing names around?

  • Corner Cases, Unexpected and Unusual Matlab

    - by Mikhail
    Over the years, reading others code, I encountered and collected some examples of Matlab syntax which can be at first unusual and counterintuitive. Please, feel free to comment or complement this list. I verified it r2006a. set([], 'Background:Color','red') Matlab is very forgiving sometimes. In this case, setting properties to an array of objects works also with nonsense properties, at least when the array is empty. myArray([1,round(end/2)]) This use of end keyword may seem unclean but is sometimes very handy instead of using length(myArray). any([]) ~= all([]) Surprisigly any([]) returns false and all([]) returns true. And I always thought that all is stronger then any. EDIT: with not empty argument all() returns true for a subset of values for which any() returns true (e.g. truth table). This means that any() false implies all() false. This simple rule is being violated by Matlab with [] as argument. Loren also blogged about it. Select(Range(ExcelComObj)) Procedural style COM object method dispatch. Do not wonder that exist('Select') returns zero! [myString, myCell] Matlab makes in this case an implicit cast of string variable myString to cell type {myString}. It works, also if I would not expect it to do so. [double(1.8), uint8(123)] => 2 123 Another cast example. Everybody would probably expect uint8 value being cast to double but Mathworks have another opinion. a = 5; b = a(); It looks silly but you can call a variable with round brackets. Actually it makes sense because this way you can execute a function given its handle. a = {'aa', 'bb' 'cc', 'dd'}; Surprsisingly this code neither returns a vector nor rises an error but defins matrix, using just code layout. It is probably a relict from ancient times. set(hobj, {'BackgroundColor','ForegroundColor'},{'red','blue'}) This code does what you probably expect it to do. That function set accepts a struct as its second argument is a known fact and makes sense, and this sintax is just a cell2struct away. Equvalence rules are sometimes unexpected at first. For example 'A'==65 returns true (although for C-experts it is self-evident). About which further unexpected/unusual Matlab features are you aware?

  • mysql PDO how to bind LIKE

    - by dmontain
    In this query select wrd from tablename WHERE wrd LIKE '$partial%' I'm trying to bind the variable '$partial%' with PDO. Not sure how this works with the % at the end. Would it be select wrd from tablename WHERE wrd LIKE ':partial%' where :partial is bound to $partial="somet" or would it be select wrd from tablename WHERE wrd LIKE ':partial' where :partial is bound to $partial="somet%" or would it be something entirely different?

    void Foo() { bool ID = "test"; var testctrl = new Control() {ID = (ID**=="abc"?ID:ID**)}; } Is it possible to get the value of ID** in the code above? The problem is they both have the same property names. Please ignore the fact the specific ID assignment is pointless, im just using it as an example.

  • Loading external pngs into an AS2 swf that is loaded into an AS3 swf wrapper

    - by James Fassett
    I have a Wrapper SWF that loads a series of AS2 movies. Each AS2 movie loads a series of .png files. AS3_wrapper.swf |-> AS2_1.swf |-> image_1.png |-> image_2.png |-> AS2_2.swf |-> image_1.png |-> image_2.png Inside of the AS2 I listen for the load of the pngs using onLoadInit and update my UI. This works fine for the first AS2 swf. But when I load the second AS2 swf the onLoadInit isn't triggered for the pngs. My guess is that the images are in a cache or something like that. I put a random string on the end of the request to try and avoid the cache but that doesn't seem to work. The code in the as2 looks roughly like this: var flagLoader:MovieClipLoader = new MovieClipLoader(); var listener:Object = new Object(); listener.onLoadInit = Delegate.create(this, handleImageLoad); flagLoader.addListener(listener); var row:MovieClip = frame1["row" + (numLoaded + 1)]; flagLoader.loadClip(predictionData[numLoaded].flag + "?r="+Math.random(), row.flag); I'm making sure to load only one image at a time (I've read anecdotal evidence loading more than one thing at a time can confuse the MovieClipLoader). For the first as2 file everything works great. When I load the second as2 file the handleImageLoad never gets called. Update: Even more perplexing is if I reload the first AS2 movie (after the second AS2 movie fails to load the images) the first AS2 movie loads the images again fine. Update 2: After trying to change from using a MovieClipLoader to polling (as was helpfully suggested) I have found some more evidence that is relevant. When I load the first AS2 files and trace from the top level clip it prints out _root. The second AS2 file when loaded traces the same _root. This lead me to check if they were clashing on names and they are. Both have a child called frame. The first one, when I trace it comes out as _root.frame as expected. The second AS2 file traces _level0.instance3.instance118.instance111.frame. I'm guessing this is related to the problem. Flash is keeping the _root of the two files the same but it is changing the locations of their children (for subsequently loaded files that have children with the same names). So either the onLoad is going to the wrong clip or the events about it loading are.

  • Finding duplicate files by content across multiple directories

    - by gagneet
    I have downloaded some files from the internet related to a particular topic. Now I wish to check if the files have any duplicates. The issue is that the names of the files would be different, but the content may match. Is there any way to implement some code, which will iterate through the multiple folders and inform which of the files are duplicates?

  • How to retrieve forbidden characters for filenames, in Java?

    - by Gnoupi
    There are some restricted characters (and even full filenames, in Windows), for file and directory names. This other question covers them already. Is there a way, in Java, to retrieve this list of forbidden characters, which would be depending on the system (a bit like retrieving the line breaker chars)? Or can I only put the list myself, checking for the system?
