Please bear with me because I am new to Android development.
I am building a widget that opens up a Configuration Activity upon placement on the home screen. When I am finished configuration and have pressed "done", the widget provider (onUpdate) is supposed to call the widget service class to bind a list of drawables to a gridview. However, the service class is not being called and the gridview is coming up empty. Any help on this is appreciated, code is included below:
*Note: i have a main.xml that has the gridview in it and another xml that has the template (imageView and textView) the gridview cell.
Manifest:
<service android:name=".WidgetService" android:permission="android.permission.BIND_REMOTEVIEWS" android:exported="false" />
<receiver android:name=".WidgetProvider" android:label="@string/app_name">
<intent-filter>
<action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
</intent-filter>
<meta-data android:name="android.appwidget.provider" android:resource="@xml/button_widget_provider" />
</receiver>
Provider:
public class WidgetProvider extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
for (int i=0; i < appWidgetIds.length; i++){
Intent intent = new Intent(context, WidgetService.class);
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.main);
remoteViews.setRemoteAdapter(appWidgetIds[i], R.id.gridview, intent);
appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
......(omitted code)}
Service:
public class WidgetService extends RemoteViewsService {
@Override
public RemoteViewsFactory onGetViewFactory(Intent intent){
return new VZRemoteViewsFactory(this.getApplicationContext(), intent);
}
}
class VZRemoteViewsFactory implements RemoteViewsService.RemoteViewsFactory{
public VZRemoteViewsFactory(Context context, Intent intent){
thisContext = context;
appWidgetId = intent.getIntExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID);
}
public void onCreate(){
// code to add drawables to list here
}
public RemoteViews getViewAt(int position){
RemoteViews remoteView = new RemoteViews(thisContext.getPackageName(), R.layout.vzwidget_item);
// setting the image view resource this way for now just for testing
remoteView.setImageViewResource(R.id.launcher_icon, R.drawable.vzicon);
remoteView.setTextViewText(R.id.textview, "test");
return remoteView;
}
.....(omitted code)}
Thank You!
