10. Once completed, Add a button to the layout and arrange it within the layout file so that it is centered horizontally. 11. Change that button's click behavior to have it update the text attribute on the TextView object to read "You have clicked the button" package edu.temple.helloworld; import ... public class MainActivity extends AppCompatActivity ( NOCOWN @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); }
