It is interesting how Android view’s touch events are dispatched. Let’s explore it.
Firstly, write a custom view and override its onTouchEvent() method.
class TouchView @JvmOverloads constructor( context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0 ) : View(context, attrs, defStyleAttr) { override fun onTouchEvent(event: MotionEvent): Boolean { Log.d("TAG", "TouchView - onTouchEvent - ${event.action}") return super.onTouchEvent(event) } } Then, in MainActivity, on the view, call setOnTouchListener() and setOnClickListener().
