        button1.setOnClickListener {
            val intent = Intent(this@MainActivity, MainActivity2::class.java)
            startActivity(intent)
        }


        button2.setOnClickListener {
            val intent = Intent(this@MainActivity, MainActivity3::class.java)
            startActivity(intent)
        }

        android:layout_height="wrap_content"
        android:text="Activity1"
        android:textSize="100dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
