    - by user117701
    I'm populating a list from the DB, and i have a image field in the DB which contains a URL to a image file. ListAdapter adapter=new SimpleCursorAdapter(this, R.layout.row, constantsCursor, new String[] {"title", "subtitle", "image"}, new int[] {R.id.value, R.id.title, R.id.icon}); However, the other fields are populated, but the image remains empty.

  • Android string formatiing from xml

    - by mann
    I am parsing xml from server. One of its node contains data like <distance>16.3432434324354324km</distance> I am putting it into hashmap like for (int i = 0; i < nl.getLength(); i++) { map.put(KEY_DISTANCE, parser.getValue(e, KEY_DISTANCE)); // adding HashList to ArrayList menuItems.add(map); } Everything is nice. But i want it two decimal places for example i want its value should be 16.34km rather then 16.343234324342342km I tried with DecimalFormat twoDForm=new DecimalFormat("##.00"); try{ Double StartVTwo=Double.valueOf(KEY_DISTANCE); Double resultDouble1 = Double.valueOf(twoDForm.format(StartVTwo)); Log.e("check", String.valueOf(resultDouble1)); }catch (NumberFormatException e){ Log.e("error"," This is error "); } But it shows exception and prints this message. Any help would be appreciated!!

  • Android: Touch seriously slowing my application

    - by Jason Rogers
    Hi all, I've been raking my brains on this one for a while. when I'm running my application (opengl game) eveyrthing goes fine but when I touch the screen my application slows down quite seriously (not noticeable on powerful phones like the nexus one, but on the htc magic it gets quite annoying). I did a trace and found out that the touch events seem to be handled in a different thread and even if it doesn't take so much processing time I think androids ability to switch between threads is not so good... What is the best way to handle touch when speed is an issue ? Currently I'm using : in the GLSurfaceView @Override public boolean onTouchEvent(MotionEvent event) { GameHandler.onTouchEvent(event); return true; } Any ideas are welcome

  • Android imageButton reset

    - by Dorin Rusu
    I have an app in which I need to use ImageButtons.The app has tabs, and when I click on a tab the ImageButton should be calling setBackgroundResource(), and when I click on another tab the imageButton should call setBackgroundColor() instead. The problem is that once the resource has been set (in my case a shape with round corners, a stroke and a transparent background), any use of setBackgroundColor() will just recolor the shape, and not the whole button. Is there a way to reset/clear the resource of an ImageButton?

  • Android: The concept for detecting changes of an opened file

    - by niko
    I wrote an application for video recording which stores the recording to a file. Currently I am looking for a way to implement some kind of "listener" to listen for file changes. The concept I would like to implement is the following: Check the file on a set period of time (for example one second), extract changes (get the data that was written in the last period) and do something with these data. I would be very thankful if anyone of you could give any suggestion or point to any useful resource that could help to solve the given problem.

  • Unable to add multiple textviews into linearLayout within a loop

    - by Adam
    for(int i=0;i<object.size();i++){ FeaturedSingleEvent event = (FeaturedSingleEvent) object.get(i); images.add(event.getImage()); LinearLayout info = new LinearLayout(this); info.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); TextView title = new TextView(this); title.setText(event.getTitle()); title.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(title); TextView by = new TextView(this); by.setText(event.getBy() + " " + event.getBy_name()); by.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(by); TextView summary = new TextView(this); summary.setText(event.getSummary()); summary.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); info.addView(summary); layout.addView(info); if(i == 0){ info.setVisibility(View.VISIBLE); }else{ info.setVisibility(View.GONE); } } I'm attempting to have multiple LinearLayouts, only one being visible at a time, to create a slideshow. In a for loop, I create the layouts with their textViews, and set only the first one to be visible. The problem is that only one TextView seems to be displaying, ie. if everything but summary is deleted, then summary will display. As of right now, only title will display, because i'm assuming it's the first one. I'm most likely doing it wrong, so any help would be appreciated.

  • Android: how do i custom arrange menu items?

    - by mtmurdock
    I would like to arrange the menu items in my app so that one item appears in its own line, and the other 3 items appear below it. I know that this is possible because i have seen apps do it. I tried writing a menu xml with linear layouts to arrange the items, but this doesnt work. I have also tried putting them in different groups, but I had no luck with that either. I know that this is possible: i have seen it done. Anyone have any ideas?

  • Android: How to declare global variables?

    - by niko
    Hi, I am creating an application which requires login. I created the main and the login activity. In the main activity onCreate method I added the following condition: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ... loadSettings(); if(strSessionString == null) { login(); } ... } The onActivityResult method which is executed when the login form terminates looks like this: @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); switch(requestCode) { case(SHOW_SUBACTICITY_LOGIN): { if(resultCode == Activity.RESULT_OK) { strSessionString = data.getStringExtra(Login.SESSIONSTRING); connectionAvailable = true; strUsername = data.getStringExtra(Login.USERNAME); } } } The problem is the login form sometimes appears twice (the login() method is called twice) and also when the phone keyboard slides the login form appears again and I guess the problem is the variable strSessionString. Does anyone know how to set the variable global in order to avoid login form appearing after the user already successfully authenticates? Thanks!

  • Download multiple files in background in Android

    - by Addev
    Basically I'm trying to make a little app for watching offline content. So there's a moment where the user selects to download the contents (and the app should download about 300 small files and images). I'd like to show the user how does the process go if he enters the proper activity. Showing a list of all the files, telling what has been already downloaded, in progress or waiting for download. My problem is that I really don't know what approach to take for achieve this. Since the download should last until finished I imagine the solution is an Service, but whats best? an IntentService, a Bound Service or an Standard Service calling a startService() for each download? And how can I keep my objects updated for displaying them later? should I use a database or objects in memory? Thanks
