50.6 Entering the First Scene

If the application were to be run now, only the blank layout represented by the activity_main.xml file would be displayed. Some code must, therefore, be added to the onCreate() method located in the MainActivity.kt file so that the first scene is presented when the activity is created. This can be achieved as follows:

package com.ebookfrenzy.scenetransitions

 

import androidx.appcompat.app.AppCompatActivity

import android.os.Bundle

import android.transition.Scene

import android.view.View

import android.transition.TransitionManager

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

class MainActivity : AppCompatActivity() {

 

    var scene1: Scene? = null

 

    override fun onCreate(savedInstanceState: Bundle?) {

        super.onCreate(savedInstanceState)

        setContentView...
