我在 RecyclerView 項目中遇到 RadioButton 問題。根據“類型”，我更改了選中的 RadioButton。但是在加載所有數據之后，當我單擊未選中的單選按鈕時，它會被選中。但是在滾動我剛剛單擊的已選中單選按鈕后，該按鈕未被選中。我想要檢查我剛剛單擊的按鈕。但它不會被檢查。我怎樣才能得到我想要的？誰能幫幫我嗎?。。。。。?！這是我的適配器類：public class AttendanceAdapterLocal extends  RecyclerView.Adapter<AttendanceAdapterLocal.ViewHolder>{    private ArrayList<StudentAttendance> attendanceArrayList;    private Context context;    public AttendanceAdapterLocal(ArrayList<StudentAttendance> attendanceArrayList) {        this.attendanceArrayList = attendanceArrayList;    }    @NonNull    @Override    public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_item_mark_attendance, viewGroup, false);        context = viewGroup.getContext();        return new ViewHolder(view);    }    @Override    public void onBindViewHolder(@NonNull final ViewHolder viewHolder, int i) {        final String type = attendanceArrayList.get(i).getType();        final String id = attendanceArrayList.get(i).getId();        final String name = attendanceArrayList.get(i).getName();        final String roll = attendanceArrayList.get(i).getRoll();        viewHolder.setData(name, roll, type, id);        final DatabaseHelper databaseHelper = new DatabaseHelper(context);        final User user = new AccessStorage(context).getUserDetails();        final String userId = user.getUserId();        viewHolder.radioPresent.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                if (databaseHelper.updateStudentAttendanceData(id, userId, "P", "0") > 0) {                    Toast.makeText(context, "Marked successfully.", Toast.LENGTH_LONG).show();                    viewHolder.radioPresent.setChecked(true);                } else {                    Toast.makeText(context, "Unable to mark attendance.", Toast.LENGTH_LONG).show();                }            }        });
