49.3 Implementing beginDelayedTransition Animation

The objective for the initial phase of this tutorial is to implement a touch handler so that when the user taps on the layout view the button view moves to the lower right-hand corner of the screen.

Open the MainActivity.kt file (located in the Project tool window under app -> java -> com.ebookfrenzy.transitiondemo) and modify the onCreate() method to implement the onTouch handler:

package com.ebookfrenzy.transitiondemo

 

import androidx.appcompat.app.AppCompatActivity

import android.os.Bundle

import android.view.MotionEvent

import android.view.View

import androidx.constraintlayout.widget.ConstraintSet

import kotlinx.android.synthetic.main.activity_main.*

        super.onCreate(savedInstanceState)
