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。请参阅文档以获取更多参考。
