The problem is that findViewById() belongs to Activity, not
AppWidgetProvider.
How could I do then ? (access myTxt field on that example)
Example :
public class Widget extends AppWidgetProvider
{
@Override
public void onUpdate(Context context, AppWidgetManager
appWidgetManager,
int[] appWidgetIds) {
context.startService(new Intent(context, UpdateService.class));
}
public static class UpdateService extends Service {
@Override
public IBinder onBind(Intent intent) {
return null;
}
public void onStart(Intent intent, int startId) {
RemoteViews updateViews = null;
try {
updateViews = buildUpdate(this);
} catch (Exception e) {
Log.i("INFO", e.toString());
}
// Push update for this widget to the home screen
ComponentName thisWidget = new ComponentName(this,
Widget.class);
AppWidgetManager manager = AppWidgetManager.getInstance
(this);
manager.updateAppWidget(thisWidget, updateViews);
}
private RemoteViews buildUpdate(Context context)
throws Exception {
RemoteViews updateViews = null;
updateViews = new RemoteViews(context.getPackageName(),
R.layout.widget_bg);
updateViews.setTextViewText(R.id.
myTxt,"Helloworld");
return updateViews;
}
}
}
