onTouchListener not accepting layout

Question

Code

private RelativeLayout mToolbar;
mToolbar = (RelativeLayout) myview.findViewById(R.id.toolbar);

mToolbar.setOnTouchListener(new View.OnTouchListener() {
        WindowManager.LayoutParams updatedParameters = finalParameters;
        double x;
        double y;
        double pressedX;
        double pressedY;

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN:

                    x = updatedParameters.x;
                    y = updatedParameters.y;

                    pressedX = event.getRawX();
                    pressedY = event.getRawY();

                    break;

                case MotionEvent.ACTION_MOVE:
                    updatedParameters.x = (int) (x + (event.getRawX() - pressedX));
                    updatedParameters.y = (int) (y + (event.getRawY() - pressedY));

                    wm.updateViewLayout(myview, updatedParameters);

                default:
                    break;
            }

            return false;
        }
    });

I have a service and this above code can move around that service in the screen... It worked before when i had to touch a button and move it around. I switched it to layout now and it does.t work anymore Why doesn't this work? The same code i used it with a button instead and it worked fine. Does onTouch always have to be button or can it be layouts or textviews as well?

Answer 1

You should return true from onTouch method

If you return false when you get MotionEvent.ACTION_DOWN , Android assumes that you're not interested in handling touch events and simply doesn't pass any other motion events to you (including MotionEvent.ACTION_MOVE that you're expecting)

Answer 2

You need to update the return part of onTouch Method

  public boolean onTouch(View v, MotionEvent event) {
    // if return is true means touch enabled
    // If return is false means touch is disabled
    return true;
    }
