如何保存所選複選標記的狀態？

Question

我有我的代碼，其中，我有2個複選框。當其中一個被選中時，另一個未被選中，反之亦然。它工作正常，除了當我點擊這個片段上的後退按鈕時，它以某種方式保存了最後選中的複選框的狀態（不會像更新內容那樣按照預期完成，只有當我點擊完成按鈕時才能完成）。另外，當我提到我的頁面或更改我的平板電腦方向時，它會恢復爲默認頁面（在本例中爲個人列表）。我想讓它工作，不僅保存所選複選框的狀態，而且也保存相關的片段內容。另外，點擊後，它不應該保存任何東西，除非我點擊完成按鈕。我知道這是在共享管理者手中完成的，但我不知道如何去做，以及在哪裏打電話，有沒有人有線索？這裏是我的代碼相同：

謝謝！ P.S：如果你能解釋我的代碼，這將是非常好的。

可以放在你的onResume代碼，那麼你的應用程序會根據自己的需要

@Override 
public void onResume(){ 
    super.onResume(); 
    // put your code here... 

}
