Problem with the auto-dismiss of dialog in setOnLongClickListener

Question

I have problem with setOnLongClickListener. When I use this method I want the dialog, which will open, to automatically close by itself (which the method's return false should do) when I take my finger off the screen. Is it possible to do this with this method, or are there other suitable methods?

Create Dialog

protected void showDialogLongClick(final int position){

        final Dialog dialog = new Dialog(activity);
        dialog.setCancelable(true);

        View v  = activity.getLayoutInflater().inflate(R.layout.onlongclick_card_mygift,null);
        dialog.setContentView(v);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

        nameLong = v.findViewById(R.id.name_longclick);
        descriptionLong = v.findViewById(R.id.gift_description);
        addressLong = v.findViewById(R.id.gift_address);
        imageCategory = v.findViewById(R.id.small_category);

        nameLong.setText(myGift.get(position).getName());
        descriptionLong.setText(myGift.get(position).getDescription());
        addressLong.setText(myGift.get(position).getAddress());
        String cat = myGift.get(position).getCategory();
        changeCategoryImage(cat, imageCategory);

        dialog.show();

    }

Listener

holder.card.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {

                showDialogLongClick(position);

                return false;
            }
        });

Answer 1

view.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_UP) {
                //Dismiss the dialog
            }
            return false;
        }
    });

view.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            //Create the dialog
            return true;
        }
    });

Use setOnLongClickListener for creating the dialog and use setOnTouchListener for dismissing the dialog.

So you should add setOnTouchListener to the view. Call dialog.dismiss() when MotionEvent action is MotionEvent.ACTION_UP (user lifts his finger).

If the view is inside a scroll view the views onTouchListener does not get called. A simple solution is to add an onTouchListener to the scroll view and dismiss the dialog when user lifts his finger.

scrollView.setOnTouchListener( new View.OnTouchListener(){
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_UP) {
                //Dismiss the dialog
                return true;
            }
            return false;
        }
    });
