How to forward click event to Launcher app?

I have a widget placed programatically on the Home screen, and I made it possible for the user to drag it to the place he wishes. I have added an OnTouchListener to the view to get motion events (so that I can remember view position on screen for next time), and it fires wherever I click on the Home screen, even when this is outside of my view.

What I would like to achieve is to forward the MotionEvent.ACTION_UP to the Launcher app so that, if user clicked on an app icon, that app will be launched. Or alternatively, NOT to receive this event when clicked outside of my view. Here's what I have done:

 LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 inflatedViewWidget = inflater.inflate(R.layout.mtc_appwidget, null);

WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                        WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
                        0,
                        PixelFormat.TRANSLUCENT);
final WindowManager wm = (WindowManager) context.getSystemService(WINDOW_SERVICE);
wm.addView(inflatedViewWidget, params);

OnTouchListener:

inflatedViewWidget.setClickable(true);
inflatedViewWidget.setOnTouchListener(new View.OnTouchListener() {
       public boolean onTouch(View v, MotionEvent event) {

                        int action = event.getAction();
                        switch (action) {
                            case MotionEvent.ACTION_UP:
                                //how to forward event to Launcher app?
                                break;
