Question

is it possible to change widget bg without using imageview?

With image i change the bg like this:

RemoteViews updateViews = new RemoteViews(EditPreferences.this.getPackageName(), R.layout.main);
updateViews.setImageViewResource(R.id.ImageView01, R.drawable.blacktrans);          
ComponentName thisWidget = new ComponentName(EditPreferences.this, HelloWidget.class);
AppWidgetManager manager = AppWidgetManager.getInstance(EditPreferences.this);
manager.updateAppWidget(thisWidget, updateViews);

What if i am not using an imageview but setting the background of the relative layout?

     android:background="@drawable/blacktrans320x100"

Is it possible? I haven’t found anything on google.

Citing CommonsWare from another topic:

You cannot modify the background that way, due to limitations in the
RemoteViews API.

What you can do is choose a different layout — one with the
background you want — when you create your RemoteViews instance for
this particular update.
