解决办法，取消布局中的代码，使用 onKeyDown onKeyUp dispatchKeyEvent 其中任意一项事件替代。

 

 @Override
    public boolean onKeyDown(int keyCode, KeyEvent event){

        System.out.println("onKeyDown keyCode:"+keyCode +" onKeyDown:"+event.getKeyCode());
        if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0){

//这里写自己的操作，此方法兼容Android 1.0到Android 2.1

        }
        return false;
    }


    @Override
    public boolean onKeyUp(int keyCode, KeyEvent event){

        System.out.println("onKeyUp keyCode:"+keyCode +" onKeyDown:"+event.getKeyCode());
        if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0){

//这里写自己的操作，此方法兼容Android 1.0到Android 2.1

        }
        return false;
    }
