Simulate the effect of pressing the HOME Key in Android Application Development

In Android Application Development, we do not want users to directly press the Back key to exit the Activity, but hide the application to the background, similar to pressing the Home Key.

The following provides sample code. For more information, see.

1 public boolean onKeyDown (int keyCode, KeyEvent event) {2 if (keyCode = KeyEvent. KEYCODE_BACK) {3 Intent intent = new Intent (Intent. ACTION_MAIN); 4 intent. setFlags (Intent. FLAG_ACTIVITY_NEW_TASK); 5 intent. addCategory (Intent. CATEGORY_HOME); 6 startActivity (intent); 7 return true; 8} 9 return super. onKeyDown (keyCode, event); 10}
