Kotlin OnTouchListener called but it does not override performClick

Question

How to override performClick in Kotlin to avoid warning?

next.setOnTouchListener(View.OnTouchListener { view, motionEvent ->
        when (motionEvent.action){
            MotionEvent.ACTION_DOWN -> {
                val icon: Drawable = ContextCompat.getDrawable(activity.applicationContext, R.drawable.layer_bt_next)
                icon.setColorFilter(Color.GRAY, PorterDuff.Mode.MULTIPLY)
                next.setImageDrawable(icon)
            }
            MotionEvent.ACTION_UP -> {
                //view.performClick()
                next.setImageResource(R.drawable.layer_bt_next)
            }
        }
        return@OnTouchListener true
    })

view.performClick does not work.

Answer 1

Okay, I solved my own problem by overriding the OnTouch listener.

override fun onTouch(view: View, motionEvent: MotionEvent): Boolean {
    when (view) {
        next -> {
            Log.d("next", "yeyy")
            when (motionEvent.action){
                MotionEvent.ACTION_DOWN -> {
                    val icon: Drawable = ContextCompat.getDrawable(activity.applicationContext, R.drawable.layer_bt_next)
                    icon.setColorFilter(Color.GRAY, PorterDuff.Mode.MULTIPLY)
                    next.setImageDrawable(icon)
                }
                MotionEvent.ACTION_UP -> {
                    view.performClick()
                    next.setImageResource(R.drawable.layer_bt_next)
                }
            }
        }
        previous -> {
            //ingredients here XD
        }
    }
    return true
}

And in that way, I can call single onTouch and implement it to many button and also can use the onClick by :

view.performClick()

Don't forget to implement :

View.OnTouchListener

And set the listener :

next.setOnTouchListener(this)
previous.setOnTouchListener(this)
