How to handle Touch Events on a Fragment?

Solution 1:

I'm not sure if I understood your problem, but I will try to answer this. So to get touch events on fragment I would do this:

-in your fragment onCreateView:

View view = inflater.inflate(R.layout.fragment_test, container, false);

    view.setOnTouchListener(new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {

                if(event.getAction() == MotionEvent.ACTION_MOVE){
                    //do something
                }
                return true;
            }
    });

//here the rest of your code

return view;

and you can check for different MotionEvents in onTouch, for example:

MotionEvent.ACTION_DOWN, MotionEvent.ACTION_UP,...

Solution 2:

In Kotlin:

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {

   val view =  inflater.inflate(R.layout.fragment_img_view, container, false)

    view.setOnTouchListener(object : View.OnTouchListener {
        override fun onTouch(v: View?, event: MotionEvent): Boolean {
            if (event.action == MotionEvent.ACTION_MOVE) {
                scaleGestureDetector.onTouchEvent(event)
            }
            return true
        }
    })
    return view
}
