Class Bundlepublic MainActivity: AppCompatActivity () { override fun onCreate (savedInstanceState: Bundle ?) { super. onCreate(savedInstanceState)setContentView(R.layout.activity_main)}}Note: The main activity file setContentView(R.layout.activity_main) is called here to implement the design process. You can find the main activity layout file in the left menu Designing Activity_main. xml: These above encodings are used to design the layout. AppCompatTextView is used to display a text.
