Widget double click

Question

I have a widget (AppWidgetProvider) and i want to know if there is a way to support multiple clicks.Example:

1)If is the first click on the widget, then the ImageButton of the widget changes (for example, changes the color).

2)If is the second time, then open an Activity.

-- There is some way to handle click events inside AppWidgetProvider?

My code:

public class MyWidgetProvider extends AppWidgetProvider
{


    @Override
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
        final int N = appWidgetIds.length;

        for (int i=0; i<N; i++) {
            int appWidgetId = appWidgetIds[i];    

            Intent intent = new Intent(context, MyActivity.class);
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);


            RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.control_widget);

            views.setOnClickPendingIntent(R.id.asdf, pendingIntent);

             appWidgetManager.updateAppWidget(appWidgetId, views);
        }    
    }
}

My widget is working fine. When i click the ImageButton(R.id.asdf), it goes to the activity MyActivity.

Id like to know how can i handle click events on my widget to make a different action (example: change the color of the ImageButton) instead of go to some activity. Is there some other way to some click handle besides setOnClickPendingIntent()?

Maybe this could help. It works for me:

public class WidgetProvider extends AppWidgetProvider {

private static final int DOUBLE_CLICK_DELAY = 500;

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {


    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
    Intent intent = new Intent(context, getClass());
    intent.setAction("Click");
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
    views.setOnClickPendingIntent(R.id.image, pendingIntent);
    appWidgetManager.updateAppWidget(appWidgetIds, views);
    context.getSharedPreferences("widget", 0).edit().putInt("clicks", 0).commit();

}

@Override
public void onReceive(final Context context, Intent intent) {

    if (intent.getAction().equals("Click")) {

        int clickCount = context.getSharedPreferences("widget", Context.MODE_PRIVATE).getInt("clicks", 0);
        context.getSharedPreferences("widget", Context.MODE_PRIVATE).edit().putInt("clicks", ++clickCount).commit();

        final Handler handler = new Handler() {
            public void handleMessage(Message msg) {

                int clickCount = context.getSharedPreferences("widget", Context.MODE_PRIVATE).getInt("clicks", 0);

                if (clickCount > 1) Toast.makeText(context, "doubleClick", Toast.LENGTH_SHORT).show();
                else Toast.makeText(context, "singleClick", Toast.LENGTH_SHORT).show();

                context.getSharedPreferences("widget", Context.MODE_PRIVATE).edit().putInt("clicks", 0).commit();
            }
        };

        if (clickCount == 1) new Thread() {
            @Override
            public void run(){
                try {
                    synchronized(this) { wait(DOUBLE_CLICK_DELAY); }
                    handler.sendEmptyMessage(0);
                } catch(InterruptedException ex) {}
            }
        }.start();
    }

    super.onReceive(context, intent);

}

}
