   if (keyCode == KeyEvent.KEYCODE_BACK) {

Answer 1

public boolean onKeyDown(int keyCode, KeyEvent event)  
    {
         if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0)
         {
            this.moveTaskToBack(true);
            return true;
         }
        return super.onKeyDown(keyCode, event);
    }

这会将活动发送到后台.有关详细参考,请参阅文档
