How to Stop Event's While Animation is in process?

Question

I am working on Animating my view where i animate the translation and scaling of View.

Problem:

If my animation duration is for 2000 ms (2 Sec) i don't want any user event's to interfere in between animation.

Example if Double Tap on View Trigger's the Scaling Animation and scrolling trigger's Translation Animation.Both animation duration is 2 seconds,But if i double tap and scroll one after another it create's weird result.

So i want to stop event's when animation is going on.

Is there any easy solution without maintaining the state of OnGoing animation and overriding the onTouchEvent to disable events?

Answer 1

Solution that i used:

• Created a State of Animation

   private var isAnimationOnGoing: Boolean = false
  

• Setting the State in Animation Listener

  translationAnimation.setAnimationListener(object : Animation.AnimationListener {
      override fun onAnimationRepeat(animation: Animation?) {
      }
  
      override fun onAnimationEnd(animation: Animation?) {
          isAnimationOnGoing = false
      }
  
      override fun onAnimationStart(animation: Animation?) {
          isAnimationOnGoing = true
      }
  })
  

• Use dispatchTouchEvent(ev: MotionEvent?) . to prevent event's to be received by the ViewGroup or by children's of ViewGroup

  override fun dispatchTouchEvent(ev: MotionEvent?): Boolean {
      val dispatchTouchEvent = super.dispatchTouchEvent(ev)
      if (isAnimationOnGoing) {
          return false
      }
      return dispatchTouchEvent
    }
