我有我的代码，其中有2个复选框。当选择其中一个时，另一个未被选中，反之亦然。它运行正常，除了当我点击这个片段上的后退按钮时，它以某种方式保存了最后一个选中复选框的状态（不按预期更新内容，只有当我点击完成按钮时才应该这样做）。此外，当我引用我的页面或更改我的平板电脑方向时，它将恢复为默认页面（在这种情况下为个人列表）。我想让它工作，不仅保存所选复选框的状态，而且还保存相关的片段内容。此外，点击后，它不应该保存任何东西，除非我点击完成按钮。我知道要在sharepreferencesmanager中完成，但我不知道如何去做以及在哪里拨打电话，有没有人有线索？这是我的相同代码：

谢谢！ P.S：如果你可以解释一下我的代码，那将会很棒。

您可以将代码放在onResume中，这样您的应用就可以根据需要使用
@Override
public void onResume(){
super.onResume();
// put your code here...
}
