Fragment를 생성해보자

class Main2Activity : AppCompatActivity() {

    var first = firstFragment()
    var second = SecondFragment()


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main2)


        button2.setOnClickListener {
            finish()
        }

        button3.setOnClickListener {
            var temp = supportFragmentManager.beginTransaction()
            temp.replace(R.id.container, first)
            temp.addToBackStack(null)
            temp.commit()
        }

        button4.setOnClickListener {
            var temp = supportFragmentManager.beginTransaction()
            temp.replace(R.id.container, second)
            temp.addToBackStack(null)
            temp.commit()
        }


    }
}
