Question

I am writing a Quiz. I have four buttons: answer options, and i am using Android multitouch! hack anyone? code snippet to disable multitouch.

But the buttons seem to work only if you tap on them very quickly.

If you slowly press the button and then release it, button only blinks, and nothing happens. Could someone help me figure out how to fix this?

Answer 1

I have used @JQCorreia hack and overrided his “onTouchEvent” like this:

        @Override
        public boolean onTouchEvent(MotionEvent event){
        int action = event.getAction() & MotionEvent.ACTION_MASK;

        switch (action) {
        case MotionEvent.ACTION_DOWN:
            for(View v: views){
                Rect r = new Rect();
                v.getGlobalVisibleRect(r);
                if (event.getX() > r.left && event.getX() < r.right
                        && event.getY() > r.top
                        && event.getY() < r.bottom) {
                    v.onTouchEvent(event);
                }
            }
            break;
        case MotionEvent.ACTION_UP:
            for(View v: views){
                Rect r = new Rect();
                v.getGlobalVisibleRect(r);
                if (event.getX() > r.left && event.getX() < r.right
                        && event.getY() > r.top
                        && event.getY() < r.bottom) {
                    v.onTouchEvent(event);
                }
            }
            break;
        case MotionEvent.ACTION_MOVE:
            for(View v: views){
                Rect r = new Rect();
                v.getGlobalVisibleRect(r);
                if (event.getX() > r.left && event.getX() < r.right
                        && event.getY() > r.top
                        && event.getY() < r.bottom) {
                }
                else{
                    v.onTouchEvent(event);
                }
            }
            break;
        }
        return true;
    }

That works for me.
