Android 如何在具有共享首选项的回收器视图上保存复选框

我有一个recycler视图，在recycler视图的行中，我有一个带有5个复选框的文本。 我的问题是每次我选中一个复选框时，共享首选项都会将所有复选框保存在同一位置

（编辑）示例：我选中第一行的复选框#2，并选中其他行的所有其他复选框#2。在我回到片段之后

这是我的适配器代码

public class HabitosAdapter extends RecyclerView.Adapter<HabitosAdapter.MyViewHolder> {
    private List<Habitos> mHabitosList;

如何仅保存选中的复选框？

我知道我只需要选中特定的复选框，而不是在所有复选框上设置一个侦听器2，但我不知道如何确切地做到这一点，我正在开发我的第一个应用程序，因此感谢您的耐心。
