  • How can I send Data from BroadcastReceiver to Widget?

    - by Yverman
    I have a BroadcastReceiver which loads data from the Internet and then it should send them back to a Widget. But how can I do this? What I've already done is updating the Widget directly from the Broadcast, but I like to just send de data back. public class UpdateManager extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget); ComponentName thisWidget = new ComponentName(context, Widget.class); remoteViews.setTextViewText(R.id.widget_textview, "UPDATE DONE"); appWidgetManager.updateAppWidget(thisWidget, remoteViews); } }

    - by Labeeb P
    Hi, Me testing in Samsung Galaxy tab. In that i have made two layout folder for both ORIENTATION_LANDSCAPE and ORIENTATION_PORTRAIT with specific layout xml in it. In that layout i have a button and on clicking it start a progress dialog (doing some stuff using AsyncTask, after that going to new intent) But when the device is rotated when the progress dialog is working, that dialog and AsyncTask stop and new layout is loaded. If i understood correctly, I think the onCreate is called when device is rotated How i can block calling onCreate while rotating device when My AsyncTask start? Thank you

  • Nullpointerexception getSystemService

    - by moppel
    Following line will only not result in a nullpointer exception if I'm connected to a WLAN: ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); Otherwise I get a nullpointer-exception straight ahead? How can I fix this? I want my background service to only work, when it is connected to wlan. But that Nullpointerexception just kills the whole app...

  • How do I overwrite the functionality of the home button?

    - by Alex
    Essentially, I just want to change the home button from just hiding my app to killing the activity that is on the screen. I thought about writing a broadcast receiver that kills the activity, but I'm not sure how to kill the activity from the receiver. How do I change the functionality of the home button to "finish" the specific activity? Thanks

  • Singleton wrapper for Context

    - by kpdvx
    I'm considering creating a singleton wrapper for a Context so my model objects, if necessary, can open and read from a database connection. My model objects do not have access to a Context, and I'd like to avoid needing to pass a reference to a Context from object to object. I was planning to place into this singleton a reference to the Context returned by Application.getApplicationContext(). This singleton object would be initialized in my custom Application instance before anything else would need to or have a chance to use it. Can anyone think of a reason to not do this?

  • Why are button sizes on Eclipse vs Device not the same.

    - by Mike Droid
    O.k....this is weird. I had my buttons looking fine last week, now something has changed. My buttons on the eclipse emulator are much larger than on my device (Droid 2.1). I checked my skin settings, screen size permissions, density factors....what am I missing? My skin is set to WVGA854, but when the app goes to the phone the buttons are smaller!? Text and pictures are fine...looking the same as the emulator...just the buttons are shrunk! Hmm....I know it has to be something simple...:)

  • Can't return data to parent activity

    - by user23
    I'm trying to return data (the position of the item picked from the grid) to parent activity, but my code fails. The debbuger shows how 'data' gets right the key and data in the "data.putExtra("POS_ICON", position)" at child activity, but after in onActivityResult() at parent activity the debbuger shows 'data' with no key nor data returned...it's like if data loses its content. I've followed other posts and tutorials but no way. Please help. Parent activity: public void selIcono(View v){ Intent intent = new Intent (this, SelIconoActivity.class); startActivityForResult(intent,PICK_ICON_REQUEST); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { //here's the problem: no data is returned!! if (requestCode == PICK_ICON_REQUEST) { if (resultCode == RESULT_OK) { // An icon was picked. putIcon(data.getIntExtra("POS_ICON", -1)); } } } Child activity: public class SelIconoActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sel_icono); GridView gridview = (GridView)findViewById(R.id.gr_iconos); gridview.setAdapter(new ImageAdapter (this)); gridview.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Intent data = new Intent(); data.putExtra("POS_ICON", position); setResult(Activity.RESULT_OK, data); finish(); } }); } }

  • How do you access country/state/province polygons in google maps api?

    - by wmh1108
    I have fairly large map overlay that I am displaying over the google maps data but would still like to see the country/state/province lines through my overlay (so the lines would essentially be on top of my overlay). As I understand, these lines are simply polygons drawn over the maps. Is there any way to access these? If so, how do I get them to show up through my overlay images?

  • Handle edittexts onKeyListener ?

    - by hungson175
    Hi everyone, I am creating login screen with 2 editTexts: etUsername and etPassword. On the etUsername, user should input the username and press Enter to go to the edit text etPassword, then he inputs the password, press Enter to login. Here are my current codes: etUsername.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { etPassword.requestFocus(); return true; } else return false; } }); etPassword.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { loginToServer(); return true; } else return false; } }); But when I input the username, and then press Enter – the program tries to log in to the server. In the debug mode, I saw that when I pressed Enter once (on the etUsername) then first: etUsername.onKey() is called and then etPassword.onKey() is also called ! Can anyone please tell me, how to implement what I want ? Thank you very much, Son

  • Key Events in TabActivities?

    - by stormin986
    I have a TabActivity and want to catch and handle presses of HOME and BACK. Where do I need to catch these events? In my subclass of TabActivity I implement the following: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { // Code handling } return super.onKeyDown(keyCode, event); } Didn't work. So I placed a breakpoint on the switch statement line. But this function never gets called, whether I press volume up/down, menu, home, or back. Where do I need to catch these KeyEvents?

  • How can I get zoom functionality for images?

    - by Janusz
    Is there a common way to show a big image and enable the user to zoom in and out and pan the image? Until now I found two ways: overwriting ImageView, that seems a little bit too much for such a common problem. using a webview but with less control over the overall layout etc.
