Delegate touch event to another view

Question

I have list view with. User can open dialog on full screen Window.FEATURE_NO_TITLE) that overlay this list view. When user touches the background of this dialog it closes.

I need to delegate this touch event to list view. I mean, after MotionEvent.ACTION_DOWN on bg i need to close dialog (it works fine), and start MotionEvent.ACTION_DOWN on list view.

I tried something like this:

((LinearLayout) findViewById(R.id.dialog_bg)).setOnTouchListener(new    View.OnTouchListener() {

            @Override
            public boolean onTouch(View v, MotionEvent event) {
                switch (event.getAction()) {
                    case MotionEvent.ACTION_DOWN:
                        MotionEvent motionEvent = MotionEvent.obtain(event);                          
                        activity.findViewById(R.id.fr_projects_list).dispatchTouchEvent(motionEvent);
                        close();

                        break;

                    default:
                        break;
                }

                return false;
            }
        });

It starts ACTION_DOWN on list view. But thats all. ACTION_MOVE and others doesn't work =/

You are dispatching only ACTION_DOWN that's why you are not getting any other actions. Try dispatching all actions.

((LinearLayout) findViewById(R.id.dialog_bg)).setOnTouchListener(new    View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
                    MotionEvent motionEvent = MotionEvent.obtain(event);                          
                    activity.findViewById(R.id.fr_projects_list).dispatchTouchEvent(motionEvent);
                    if(event.getAtction==MotinEvent.ACTION_UP) close();
                    return false;
        }
    });

After i make touch event i close dialog. So after that there will no others events on dialog. And i should with events of list view. – Suvitruf - Andrei Apanasik Jan 30 '15 at 11:35
@Suvitruf I updated my answer. Just a try.. Call Close only when action is ACTION_UP – Praveena Jan 30 '15 at 14:38
Customer wants to close dialog on ACTION_DOWN, not ACTION_UP. It's not my choice )= – Suvitruf - Andrei Apanasik Jan 30 '15 at 14:56
Ok.. I guess if you close dialogue on ACTION_DOWN, theynother event should by default called on ListView. Try setting touchlistner to your listview. I am not 100% sure but you can try. – Praveena Jan 30 '15 at 15:12
This is helpfull, but it doesn't work in 100% if target view has margin then cloned touch will be dislocated a bit. Any help with this problem? – ElSajko Oct 04 '15 at 23:53
