  • Poor Transparency on Images

    - by KyleStew
    I am having problems getting transparency to work well on an ImageView. The images at (http://img265.imageshack.us/img265/6233/whatn.png) were screen captured from a Droid (hdpi). The top image I made in Photoshop and left the background white. The bottom image is the same image with the background transparent and the layout's color (white) shows through. Whenever I have transparent backgrounds in images it dithers shadows like this. Also, it only happens on hdpi devices, on my G1 (mdpi) it looks just fine. What is going on? How can I make the bottom image look as good as the top one?

  • Runnable to be run every second only runs once in Fragment onCreateView()

    - by jul
    I'm trying to update the time in a TextView with a Runnable supposed to be run every second. The Runnable is started from a Fragment's onCreateView(), but it's only executed once. Anybody can help? Thanks public class MyFragment extends Fragment { Calendar mCalendar; private Runnable mTicker; private Handler mHandler; TextView mClock; String mFormat; private boolean mClockStopped = false; @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { RelativeLayout view = (RelativeLayout) inflater.inflate(R.layout.meteo_widget, container, false); /* * Clock (from DigitalClock widget source) */ mClock = (TextView) view.findViewById(R.id.clock); mCalendar = Calendar.getInstance(); mHandler = new Handler(); mTicker = new Runnable() { public void run() { if(mClockStopped) return; mCalendar.setTimeInMillis(System.currentTimeMillis()); mClock.setText(DateFormat.format("hh:mm:ss", mCalendar)); mClock.invalidate(); long now = SystemClock.uptimeMillis(); long next = now + (1000 - now % 1000); mHandler.postAtTime(mTicker, next); } }; mTicker.run(); return view; } @Override public void onResume() { super.onResume(); mClockStopped = true; } @Override public void onPause() { mClockStopped = false; super.onPause(); } }

  • How can you tell if an activity is starting or resuming?

    - by Joren
    I have an activity which pulls some JSON from my server, and then uses it to draw a list. That list launches further activities. My problem is that I can't figure out a way to tell if the activity is still alive when you go back to it, so I end up re-querying my JSON from the server and redrawing the list every time the user goes back to the activity. How can I tell if my activity is still alive so I can skip the redraw? Using onRestart works for hitting the home key then going back, but onCreate not onRestart is called if I selected a list item then hit back.

  • Determining filetype of file in assets folder

    - by ChaimKut
    Question: How do you programmatically distinguish between directories and regular files in the assets folder? When using AssetManager to access files in the assets folder, it seems impossible to determine if a file is in fact a file or a directory. You get the list of files from the list method and then open the file using the open method. I thought perhaps using the openFd method to get the asset file descriptor (and then subsequently requesting the normal file descriptor) would provide me some information. But requesting the file descriptor for a directory results in an IOException (which makes sense since what would it mean for a directory to have a file descriptor...?). Currently I'm relying on that IOException (resulting from attemptng to open a directory in the assets folder) in order to determine if a file is in fact a directory. (Opening a regular file works just fine). This seems like a bad idea. Any other suggestions to distinguish between a file and a directory?

  • Updating a TextView with a SeekBar's value (ultra-slow)

    - by Peter Bjorn
    Now look at that! I am having trouble with one of the simplest goals: updating a plain TextView with the value of a SeekBar. This is my approach: @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { if (fromUser) { mInfoText.setText(mFunction.getUserFriendlyString(progress)); } } It basically works, but it kind of blocks the whole UI when I'm dragging. (Note: I tried both View.post() and Activity.runOnUiThread()). Am I overlooking something?

  • How to pass Itemized Overlay from a class to a Listener Class.

    - by Taylor
    Hey guys, I tried searching the forums on this one, but I wasn't able to find anything on my problem. To describe my problem, everytime my location changes, it redraws the center maker on the map.... Only catch is that it doesn't delete the previous one. I can get it to delete the previous one when the location is changed, but I have no idea how to pass the original overlay in-between classes. Also, pastebin here Thanks in advance, hwrd

  • How to set webview scroll position within it on initial launch ?

    - by mob-king
    I have an issue with Webview to set the initial scroll position within it when first launched. By default it is left , I want it to scroll and show the view from center. Or is it possible to resize the view to fit the screen width initially, instead of scroll bars. I need this since the left part of the page I am loading is blank making user feel the page is not loaded.

  • Can an app delete its own internal resources?

    - by user637884
    I am trying to find a way to delete an internal resource after an app installs. More specifically, I have a zip file included in the apk, that I unzip to the SD Card when the app is first run. But then want to delete the now unneeded zip file (the purpose being to save the user internal phone memory). I access the zip file with, Resources resources = this.getResources(); InputStream is = resources.openRawResource(R.raw.assets); But am uncertain how to then delete the resource (if even possible). I know one may ask why not simply install the app to SD Card at download. But the app includes a screen widget, and installing apps to the SD Card and using a screen widget is problematic. Thanks, Matt

  • What values does Camera.Parameters.set("picture-size", ?) take?

    - by mobilekid
    Hi, my app involves some work with the camera, therefore it needs to handle capturing of images with different resolution. My targets are 1.6 - onwards. Does anyone know what to pass in the value argument for Camera.Parameters.set("picture-size", value) I have look at the Donut release of the Camera app, however, it was not very clear what exactly has been used there as the value is retrieved from the SharedPreferences. // Set picture size parameter. String pictureSize = mPreferences.getString(CameraSettings.KEY_PICTURE_SIZE, getString(R.string.pref_camera_picturesize_default)); mParameters.set(PARM_PICTURE_SIZE, pictureSize); Lookin at the strings.xml I can see that R.string.pref_camera_picturesize_default = 2048x1536, however, I'm not sure what other values can be passed there? Is it any resolution you fancy, or are they only certain resolutions the drivers can handle? Thanks.

    - by user313135
    Hello, I have a shared preference that is being accesed via an EditTextPreference. I am in the process of porting this application to a device that does not have a hardware keyboard for text entry. When the time comes to modify the EditTextPreference, there is no soft keyboard that becomes available, and I am at a loss as to how to invoke the soft keyboard for text input to edit this preference. Thanks

  • opengl es render but dont show on display

    - by Sponge
    i have written a object selection algorithm which picks the objects by there color. i give every object an unique color and then i just have to use the glReadPixels method to check which object was selected this works fine and is really fast but the problem is that the frame is displayed on the screen with all the picking-colors so the screen flashes every time you select something. so my question is: how do i write everything in the correct display buffer but dont display it on the screen to avoid these flashes?

  • Serializable object in intent returning as String

    - by B_
    In my application, I am trying to pass a serializable object through an intent to another activity. The intent is not entirely created by me, it is created and passed through a search suggestion. In the content provider for the search suggestion, the object is created and placed in the SUGGEST_COLUMN_INTENT_EXTRA_DATA column of the MatrixCursor. However, when in the receiving activity I call getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY), the returned object is of type String and I cannot cast it into the original object class. I tried making a parcelable wrapper for my object that calls out.writeSerializable(...) and use that instead but the same thing happened. The string that is returned is like a generic Object toString(), i.e. com.foo.yak.MyAwesomeClass@4350058, so I'm assuming that toString() is being called somewhere where I have no control. Hopefully I'm just missing something simple. Thanks for the help! Edit: Some of my code This is in the content provider that acts as the search authority: //These are the search suggestion columns private static final String[] COLUMNS = { "_id", // mandatory column SearchManager.SUGGEST_COLUMN_TEXT_1, SearchManager.SUGGEST_COLUMN_INTENT_EXTRA_DATA }; //This places the serializable or parcelable object (and other info) into the search suggestion private Cursor getSuggestions(String query, String[] projection) { List<Widget> widgets = WidgetLoader.getMatches(query); MatrixCursor cursor = new MatrixCursor(COLUMNS); for (Widget w : widgets) { cursor.addRow(new Object[] { w.id w.name w.data //This is the MyAwesomeClass object I'm trying to pass }); } return cursor; } This is in the activity that receives the search suggestion: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Object extra = getIntent().getSerializableExtra(SearchManager.EXTRA_DATA_KEY); //extra.getClass() returns String, when it should return MyAwesomeClass, so this next line throws a ClassCastException and causes a crash MyAwesomeClass mac = (MyAwesomeClass)extra; ... }

  • Thread loses Message after wait() and notify()

    - by fugu2.0
    Hey Guys! I have a problem handling messages in a Thread. My run-method looks like this public void run() { Looper.prepareLooper(); parserHandler = new Handler { public void handleMessage(Message msg) { Log.i("","id from message: "+msg.getData.getString("id")); // handle message this.wait(); } } } I have several Activities sending messages to this thread, like this: Message parserMessage = new Message(); Bundle data = new Bundle(); data.putString("id", realId); data.putString("callingClass", "CategoryList"); parserMessage.setData(data); parserMessage.what = PARSE_CATEGORIES_OR_PRODUCTS; parserHandler = parser.getParserHandler(); synchronized (parserHandler) { parserHandler.notify(); Log.i("","message ID: " + parserMessage.getData().getString("id")); } parserHandler.sendMessage(parserMessage); The problem is that the run-method logs "id from message: null" though "message ID" has a value in the Log-statement. Why does the message "lose" it's data when being send to the thread? Has it something to do with the notify? Thanks for your help

  • Calling a function that has 'Activity' as an argument.

    - by Andrew
    I have stripped down my functions for simplicity: public static int countLines(String fileName, Activity activity) throws IOException { BufferedReader in = new BufferedReader(new InputStreamReader(activity.getAssets().open(fileName))); return 3; } I am calling it from here: private CharSequence RandomRead() throws IOException { int numberLines = countLines("data.txt", ??????); return "Success" } In the call to countLines("data.txt", ??????), what do I put as the argument for the Activity? I've Googled all night and I can find no examples of an actual call to a function where Activity is an argument. (Lots of examples actually using 'activity', but no calls to the example functions). Thanks!

  • Play bitmap animation list in reverse order?

    - by Ixx
    I have a bitmap animation defined in XML, to open a door. I also need to animate closing the door, which contains the same frames but in reverse order. I don't want to create a second XML for this. The only reverse parameter I found in the documentation is related with repeating, and this doesn't apply, since I want the opening animation to finish when the door is closed and not continue to closing animation. I also found some threads about using a custom interpolator, but can I use / makes sense with a bitmap animation? How can I play the XML animation in reverse order?

  • What benefits can Java developer have moving to a *NIX platform?

    - by dave-keiture
    Hi everyone, A friend of mine is a Java developer, who's using *NIX for ages. He claims that *NIX is for real Java geeks, whereas WIN is for dummies (and I'm one of them, according to him) and girls. When I ask him to argue his position, and explain, what's so good for Java developer on *NIX, he starts talking about console, wget, curl and grep. But sorry, wget and curl analogues exist for the WIN platform as well. As for the console - I'm using FAR Commander, and have access to the command line when I need. Moreover, even if I decide moving to *NIX, I will certainly use Netbeans or Eclipse there, so there will be no big difference. Guys, who use Java on *NIX, could you please give me a real killer examples, when *NIX (any util or technique) dramatically increases Java development productivity (in the way the hints are given in "The Pragmatic Programmer"), or, which is also important, gives more fun from the process. Thanks in advance!

  • Pass a Message From Thread to Update UI

    - by Jay Dee
    Ive created a new thread for a file browser. The thread reads the contents of a directory. What I want to do is update the UI thread to draw a graphical representation of the files and folders. I know I can't update the UI from within a new thread so what I want to do is: whilst the file scanning thread iterates through a directories files and folders pass a file path string back to the UI thread. The handler in the UI thread then draws the graphical representation of the file passed back. public class New_Project extends Activity implements Runnable { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { Log.d("New Thread","Proccess Complete."); Intent intent = new Intent(); setResult(RESULT_OK, intent); finish(); } }; public void getFiles(){ //if (!XMLEFunctions.canReadExternal(this)) return; pd = ProgressDialog.show(this, "Reading Directory.", "Please Wait...", true, false); Log.d("New Thread","Called"); Thread thread = new Thread(this); thread.start(); } public void run() { Log.d("New Thread","Reading Files"); getFiles(); handler.sendEmptyMessage(0); } public void getFiles() { for (int i=0;i<=allFiles.length-1;i++){ //I WANT TO PASS THE FILE PATH BACK TU A HANDLER IN THE UI //SO IT CAN BE DRAWN. **passFilePathBackToBeDrawn(allFiles[i].toString());** } } }
