  • Overllaping view elements

    - by rantravee
    Hi, Here's the problem I'm facing : I've got a custom slider that controlls the volume and a label "volume" that I combine together in a liniar Layout to obtain a volume control setting. In the emulator and on a G1 phone these look pretty ok , however , when put on a Xperia mini the label and the slider overlap . What should I do obtain a decent view independent of the device the application runs ?

  • How do I animate View.setVisibility(GONE)

    - by MrSnowflake
    I want to make an Animation for when a View gets it's visibility set to GONE. Instead of just dissapearing, the View should 'collapse'. I tried this with a ScaleAnimation but then the View is collapse, but the layout will only resize it's space after (or before) the Animation stops (or starts). How can I make the Animation so that, while animating, the lower Views will stay directly below the content, instead of having a blank space?

  • discrepancy in using AsyncTask, code is executed in weird order

    - by Pentium10
    Hello, In onCreate method I hav the following order of code objItem = new DbClass(this);//the onCreate event creates the database new PrepareAdapter1().execute();//this task uses the tables, but SQLException occures, tables doesn't exists As you see in my short code, I get a new instance of the SQLiteOpenHelper class, which does create the tables in onCreate. And after that I start an AsyncTask instance where I use the created table. But I get SQLiteException as table doesn't not exists. I am using this code in wrong way? I expect the table to be created when I launch the thread.

  • How to manipulate data after its retrieved via remote database

    - by bMon
    So I've used code examples from all over the net and got my app to accurately call a .php file on my server, retrieve the JSON data, then parse the data, and print it. The problem is that its just printing to the screen for sake of the tutorial I was following, but now I need to use that data in other places and need help figuring out that process. The ultimate goal is to return my db query with map coordinates, then plot them on a google map. I have another app in which I manually plot points on a map, so I'll be integrating this app with that once I can get my head around how to correctly manipulate the data returned. public class Remote extends Activity { /** Called when the activity is first created. */ TextView txt; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Create a crude view - this should really be set via the layout resources // but since its an example saves declaring them in the XML. LinearLayout rootLayout = new LinearLayout(getApplicationContext()); txt = new TextView(getApplicationContext()); rootLayout.addView(txt); setContentView(rootLayout); // Set the text and call the connect function. txt.setText("Connecting..."); //call the method to run the data retreival txt.setText(getServerData(KEY_121)); } public static final String KEY_121 = "http://example.com/mydbcall.php"; private String getServerData(String returnString) { InputStream is = null; String result = ""; //the year data to send //ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(); //nameValuePairs.add(new BasicNameValuePair("year","1970")); try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost(KEY_121); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); }catch(Exception e){ Log.e("log_tag", "Error in http connection "+e.toString()); } //convert response to string try{ BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } is.close(); result=sb.toString(); }catch(Exception e){ Log.e("log_tag", "Error converting result "+e.toString()); } //parse json data try{ JSONArray jArray = new JSONArray(result); for(int i=0;i<jArray.length();i++){ JSONObject json_data = jArray.getJSONObject(i); Log.i("log_tag","longitude: "+json_data.getDouble("longitude")+ ", latitude: "+json_data.getDouble("latitude") ); //Get an output to the screen returnString += "\n\t" + jArray.getJSONObject(i); } }catch(JSONException e){ Log.e("log_tag", "Error parsing data "+e.toString()); } return returnString; } } So the code: returnString += "\n\t" + jArray.getJSONObject(i); is what is currently printing to the screen. What I have to figure out is how to get the data into something I can reference in other spots in the program, and access the individual elements ie: double longitude = jArray.getJSONObject(3).longitude; or something to that effect.. I figure the class getServerData will have to return a Array type or something? Any help is appreciated, thanks.

  • Supress the Soft Keboard when an activity loads... yet again

    - by tunneling
    this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); Same problem that I've read on other posts. I don't want the soft keyboard to pop up when the Activity loads. The above code snippet works, however my View no longer scrolls up so that the User can still see the EditText. It scrolls without this line of code. Any ideas?

  • Play playlist with MediaPlayer

    - by Kaloer
    Hi, I'm trying to play a playlist I get using the MediaStore provider. However, when I try playing a playlist nothing happens. Can a MediaPlayer play a playlist (m3u file) and do I need to set the first track to play ? This is my test code in the onCreate() method: Uri uri = MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI; if(uri == null) { Log.e("Uri = null"); } String[] projection = new String[] { MediaStore.Audio.Playlists._ID, MediaStore.Audio.Playlists.NAME, MediaStore.Audio.Playlists.DATA }; Cursor c = managedQuery(uri, projection, null, null, null); if(c == null) { Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_error, Toast.LENGTH_LONG).show(); return; } if(!c.moveToFirst()) { c.close(); Toast.makeText(getApplicationContext(), R.string.alarm_tone_picker_no_music, Toast.LENGTH_LONG).show(); return; } c.moveToFirst(); try { MediaPlayer player = new MediaPlayer(); player.setDataSource(c.getString(2)); player.start(); } catch(Exception e) { e.printStackTrace(); } I have turned on every volume stream. Thanks you, Kaloer

  • I need to recover an instance of an activity

    - by Bilthon
    Well.. the title is pretty descriptive, I have a bunch of tab activities (which I implemented myself, didn't want to use the tabviews with activities inside them), so It's basically 5 activities calling each other every time the user clicks on the tabs displayed as a row of LinearLayouts at the bottom of the screen. The thing is that the way I do it now, everytime the user jumps from one activity to another, a new activity is created and launched. Of course, I can see I'm wasting resources this way. So what I would like to do is to create every activity only once; and then if the user wants to go back to the previous (or any one that was already created and is probably paused) just check on some kind of list or array to see if the activity can be recovered and only in the case it can't; to lauch a new one. My question is, how can I check this? should I save the intents? and how to recover the activities afterwards? I'm kind of new with java. Greetings Nelson R. Perez

    the least thing i like on the nexus one is the useless app it runs when on the desktop dock. I already wasted a good day searching for the 3 topics below and failed to find anything.

  • Null Pointer Exception in my BroadcastReceiver class

    - by user1760007
    I want to search a db and toast a specific column on the startup of the phone. The app keeps crashing and getting an exception even though I feel as the code is correct. @Override public void onReceive(Context ctx, Intent intent) { Log.d("omg", "1"); DBAdapter do = new DBAdapter(ctx); Log.d("omg", "2"); Cursor cursor = do.fetchAllItems(); Log.d("omg", "3"); if (cursor.moveToFirst()) { Log.d("omg", "4"); do { Log.d("omg", "5"); String title = cursor.getString(cursor.getColumnIndex("item")); Log.d("omg", "6"); // i = cursor.getInt(cursor.getColumnIndex("id")); Toast.makeText(ctx, title, Toast.LENGTH_LONG).show(); } while (cursor.moveToNext()); } cursor.close(); } The frustrating part is that I don't see any of my "omg" logs show up in logcat. I only see when my application crashes. I get three lines of errors in logcat. 10-19 12:31:11.656: E/AndroidRuntime(1471): java.lang.RuntimeException: Unable to start receiver com.test.toaster.MyReciever: java.lang.NullPointerException 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.DBAdapter.fetchAllItems(DBAdapter.java:96) 10-19 12:31:11.656: E/AndroidRuntime(1471): at com.test.toaster.MyReciever.onReceive(MyReciever.java:26) For anyone interested, here is my DBAdapter fetchAllItems code: public Cursor fetchAllItems() { return mDb.query(DATABASE_TABLE, new String[] { KEY_ITEM, KEY_PRIORITY, KEY_ROWID }, null, null, null, null, null); }

  • How could I make the SurfaceView and Button have a different orientation in a Activity

    - by ???
    I hava a simple program about video recording . I use the surfaceView to show the preview screen. and I also want to put some buttons on the screen. I put all the component mentioned above into a XML file which is "ipcam.xml" I use MediaRecorder , SurfaceView , SurfaceHolder to complete this program because the preview screen does not orientate correctly when I rotate my phone. so I use "setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);" but , the button in the program is always in LANDSCAPE direction . it will not auto change direction when I rotate my phone , but the preview is ok!! so is there anyway to solve this problem. Thank you all very much in advance.

    Problem I send the message "12345" from the socket server to the client: myPrintWriter.println("12345"); After that I read this message on client: int c; while ((c = inputStream.read( )) != -1) { byte[] buffer2 = new byte[1]; buffer2[0] = (byte) c; String symbol = new String(buffer2 , "UTF-8"); String symbolCode = Integer.toString((int)buffer2[0]); Log.v(symbol, symbolCode); } Log.v("c == -1", "Disconnected"); What I see in log: With out.println("abcrefg"); Why? I think it's line termination symbol. I need to get string "12345" or any other and next strings correctly. Help me please.
