                if(keyCode == KeyEvent.KEYCODE_HOME)    
                {
                    todoItems.add(0, myEditText.getText().toString());
                    aa.notifyDataSetChanged();
                    return true;
                }
            } 

too with KEYCODE_DPAD_CENTER but no capture the centre button

anyone know the keycode for this button?

Thanks you very much

Answer 1

you can't catch whether the home button was pressed .Using KeyCodes doesn't seem to work for HOME Android has kept the functionality of home button separate from other keys. The preferred way is to deal with onStop() of your Activity being called when the user presses HOME.

@Override
protected void onStop() 
{
    super.onStop();
//put your logic here 
}
