You can only attach a widget to a view if you use the pick app widget
intent.
You can attach as many as you want, I didn't see a limit yet.
I can point you to a working sample I used:
http://www.anddev.org/advanced-tutorials-f21/appwidgethost-tutorial-t10329.html
Only thing you need to fix is this part:
1. protected void doWidgetPick() {
2.
3. int appWidgetId = WidgetScreen.this.mAppWidgetHost.
allocateAppWidgetId();
4.
5.
6.
7. Intent pickIntent = new Intent(AppWidgetManager.
ACTION_APPWIDGET_PICK);
8.
9. pickIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID,
appWidgetId);
10.
Remove WidgetScreen.
Should compile after that.
If you ever find a way to save the widgets and restore them, I would love to
hear your solution.
