  • ListView Item Detail Screen: New or Same Activity?

    - by stormin986
    I have a listview where each item correlates to an instance of an item in an array. When the user selects an item, it will bring up a 'Details' page that reads and displays other data members of the list item. Would this be better implemented with the Details page as its own activity, or a new view within the same activity? Pros and cons of each? A new activity makes my job a little easier in terms of handling the 'back' button, but then I have the challenge of how do I pass the rest of the data structure to the new activity since I can't bundle it up (unless I serialize it).

  • 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?

  • 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); } }

  • 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?

  • How do I Capture native (Menu) button presses in PhoneGap?

    - by Dinedal
    By calling "BackButton.override();" and then hooking on to the backKeyDown event, I am able to get the back button press to register. But there doesn't appear to be a "MenuButton.override();" Also, hooking on the menuKeyDown doesn't register a button press. Here's my (non-functional) code. What am I missing? <script type="text/javascript" charset="utf-8" src="phonegap.js"></script> <script type="text/javascript" charset="utf-8"> document.addEventListener("deviceready", function() { alert('initialized'); }, false); document.addEventListener("menuKeyDown", function() { alert('menu_pressed'); // Never happens }, false); </script>

  • 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(); } }); } }

  • 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 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
