  • MapView without extending MapActivity

    - by Michal Dymel
    Is there a way to display a MapView without extending MapActivity? I have other Activity class which I'm extending and I would prefer not to change that... I've seen that you can inflate using MapActivity, but didn't find any spec/examples on how to do it.

  • Error Instantiating an Inner Class in Parent's Constructor...

    - by stormin986
    In my application's main class (subclass of Application), I have a public inner class that simply contains 3 public string objects. In the parent class I declare an object of that inner class. public class MainApplication extends Application { public class Data { public String x; public String y; public String z; } private Data data; MainApplication() { data = new Data() data.x = "String"; } } After I instantiate the object in the constructor, I get a runtime error when I try to assign any of the inner class object's variables. Any idea what's up here??

  • Weird stuttering issues not related to GC.

    - by Smills
    I am getting some odd stuttering issues with my game even though my FPS never seems to drop below 30. About every 5 seconds my game stutters. I was originally getting stuttering every 1-2 seconds due to my garbage collection issues, but I have sorted those and will often go 15-20 seconds without a garbage collection. Despite this, my game still stutters periodically even when there is no GC listed in logcat anywhere near the stutter. Even when I take out most of my code and simply make my "physics" code the below code I get this weird slowdown issue. I feel that I am missing something or overlooking something. Shouldn't that "elapsed" code that I put in stop any variance in the speed of the main character related to changes in FPS? Any input/theories would be awesome. Physics: private void updatePhysics() { //get current time long now = System.currentTimeMillis(); //added this to see if I could speed it up, it made no difference Thread myThread = Thread.currentThread(); myThread.setPriority(Thread.MAX_PRIORITY); //work out elapsed time since last frame in seconds double elapsed = (now - mLastTime2) / 1000.0; mLastTime2 = now; //measures FPS and displays in logcat once every 30 frames fps+=1/elapsed; fpscount+=1; if (fpscount==30) { fps=fps/fpscount; Log.i("myActivity","FPS: "+fps+" Touch: "+touch); fpscount=0; } //this should make the main character (theoretically) move upwards at a steady pace mY-=100*elapsed; //increase amount I translate the draw to = main characters Y //location if the main character goes upwards if (mY<=viewY) { viewY=mY; } }

  • Getting a Soft Keyboard for a EditTextPreference

    - 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

  • EditText items in a scrolling list lose their changes when scrolled off the screen

    - by ianww
    I have a long scrolling list of EditText items created by a SimpleCursorAdapter and prepopulated with values from an SQLite database. I make this by: cursor = db.rawQuery("SELECT _id, criterion, localweight, globalweight FROM " + dbTableName + " ORDER BY criterion", null); startManagingCursor(cursor); mAdapter = new SimpleCursorAdapter(this, R.layout.weight_edit_items, cursor, new String[]{"criterion","localweight","globalweight"}, new int[]{R.id.criterion_edit, R.id.localweight_edit, R.id.globalweight_edit}); this.setListAdapter(mAdapter); The scrolling list is several emulator screens long. The items display OK - scrolling through them shows that each has the correct value from the database. I can make an edit change to any of the EditTexts and the new text is accepted and displayed in the box. But...if I then scroll the list far enough to take the edited item off the screen, when I scroll back to look at it again its value has returned to what it was before I made the changes, ie. my edits have been lost. In trying to sort this out, I've done a getText to look at what's in the EditText after I've done my edits (and before a scroll) and getText returns the original text, even though the EditText is displaying my new text. It seems that the EditText has only accepted my edits superficially and they haven't been bound to the EditText, meaning they get dropped when scrolled off the screen. Can anyone please tell me what's going on here and what I need to do to force the EditText to retain its edits? Thanks Ian

  • Need to pick contact from a dialog preference

    - by MLW
    I would like to add a preference setting that uses an ACTION_PICK intent. My goal is to acquire the phone number of a contact in my phone by using a preference. Is this possible? I can run this code from my activity but I discovered I cannot run it from a class that extends DialogPreference. Intent intentContact = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intentContact, PICK_CONTACT); Or is there a way to start a new activity from a preference? Then that activity could execute the above two lines of code?

  • How to show own view in Spinner Widget instead of Text View?

    - by Janusz
    I have a selection for some items using a spinner widget. At the moment the spinner will load a simple Textview and show the name of the item. It is possible to define an own view to show inside the spinner row? I would suspect it being similar to a custom List row. I simply want to show an individual icon left from the spinner text for each item in the list.

  • setting ringtone for a specific application only.

    - by Umesh
    I want to be able to set a ringtone which is associated to a particular application only. If the message with a special prefix arrives, my application intercepts it and does whatever it has to do. On message arriving, i want to be able to tell the user that the 'special' message has arrived, through a ringtone( which exclusively plays upon that kind of msg). anyone with a lead, please help.

  • How do I get a preference to correlate to variable?

    - by Dan T
    I have my menu button bringing up a Settings option, which brings up numerous ListPreferences such as weight and various sizes for glasses (it's a BAC calculator app). I'll pick one example... weight will work. Depending on how much you weigh it will affect your BAC. I have a int for Weight, set at 180. I would like someone to be able to go into the menu Settings, pick the "Weight" ListPreference, and choose between 100, 130, 150, 180, 210, 240, 270, and 300. I already have the numbers show up (all of the arrays have been created) and I can choose one, but it doesn't do anything because it's not linked up with the int Weight variable. How do I go about linking the information?

  • Java convert JSONObject to URL parameter

    - by Alex Ivasyuv
    What is the elegant way to convert JSONObject to URL parameters. For example, JSONObject: {stat: {123456: {x: 1, y: 2}, 123457: {z: 5, y: 2}}}} this should be like: stat[123456][x]=1&stat[123456][y]=2&stat[123457][z]=5&stat[123457][y]=2 of course with escaped symbols, and of course JSON object could be more complicated.. Maybe there already exist some mechanisms for that? 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?

  • How to rotate a drawable with anti-aliasing enabled

    - by Mike
    I need to rotate an ImageView by a few degrees. I'm doing this by subclassing ImageView and overloading onDraw() @Override protected void onDraw(Canvas canvas) { canvas.save(); canvas.scale(0.92f,0.92f); canvas.translate(14, 0); canvas.rotate(1,0,0); super.onDraw(canvas); canvas.restore(); } The problem is that the image that results shows a bunch of jaggies. How can I antialias an ImageView that I need to rotate in order to eliminate jaggies? Is there a better way to do this?

  • Giant online image gallery - How do I avoid OutOfMemoryError?

    - by Ben L.
    For anyone who's wondering, the gallery is http://www.spore.com/sporepedia. My app uses the Spore API to get the 100 newest creations, then displays them in a GridView. The text data about the creations is easy to store, but the images present a problem. As far as I know, I can either keep the images in a Hashtable or grab them every time they are viewed. Neither of these will work - the Hashtable quickly presents an OutOfMemoryError, and the constant reloading causes a lot of load on the server and a lot of lag on the client. Is there a better way to store the images?

  • How to tell which thread(s) are producing all the garbage?

    - by Brad Hein
    I have an app with about 15 threads. Most do mundane tasks and sleep most of their lives. Others collect information and cache it in hashmaps. The hashmaps grow to a moderate size and level out. The number of keys and size of value remains constant, but the contents of the values changes (at 33 keys per second average). When I start my app, I notice the garbage collection interval goes from minutes to once per second, and the amount of garbage is 700k+ each time. In fact as I was writing this, it caused my phone to reboot with an error "Referencetable Overflow". Here's my question: Are there any tricks to identifying which threads are producing the garbage, or even finding out more about what garbage they are producing?

  • 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());** } } }

  • HttpURLConnection! Connection.getInputStream is java.io.FileNotFoundException

    - by user3643283
    I created a method "UPLPAD2" to upload file to server. Splitting my file to packets(10MB). It's OK (100%). But when i call getInputStream, i get FileNotFoundException. I think, in loop, i make new HttpURLConnection to set "setRequestProperty". This is a problem.

  • How to change ScrollView's position after touch?

    - by Matt
    I'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp. I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list? Thanks!
