Recycler View 不调用 onBindviewHolder

Question

OnBindViewHolder isn't called when I try to select an element inside the recycler view. I'm using a horizontal layout with all the elements not showing initially (4 out of 7 elements are showing and when user motions to right the 3 elements alternate). Usually, when the user clicks an element OnBindViewHolder is supposed to fire but it's not happening for me. The only time it fires is on initialization. Since it doesn't fire I can't click any of the elements inside the recycler view. Maybe it might have to do with my layouts? I'm not sure

MyAdapter

public MyAdapter(){
    this.setHasStableIds(true);
}


//Set Keys
public void setSelectionTracker(SelectionTracker<Long> selectionTracker) {
    this.mSelectionTracker = selectionTracker;
}

public static class MyViewHolder extends RecyclerView.ViewHolder{
    public TextView dayView, numberView;
    public View view;
    ScheduleDetails scheduleDetails = new ScheduleDetails();

    public MyViewHolder(View itemView){
        super(itemView);
        view = itemView;
        dayView = itemView.findViewById(R.id.day);
        numberView = itemView.findViewById(R.id.day_number);
    }

    void bind(int position, String dayInit, String numberInit, Boolean isSelected){
        scheduleDetails.position = position;
        System.out.println("Hit2: " + scheduleDetails.position);

        dayView.setText(dayInit);
        numberView.setText(numberInit);
        view.setSelected(isSelected);

    }

    public ItemDetailsLookup.ItemDetails<Long> getItemDetails(@NonNull MotionEvent motionEvent){
        return scheduleDetails;
    }
}

static class ScheduleDetails extends ItemDetailsLookup.ItemDetails<Long>{
    int position;
    Long identifier;

    @Override
    public int getPosition() {
        return position;
    }

    @Nullable
    @Override
    public Long getSelectionKey() {
        return identifier;
    }

    @Override
    public boolean inSelectionHotspot(@NonNull MotionEvent e){
        return true;
    }
}

public MyAdapter(String[] day, String[] number){
    days = day;
    numbers = number;
}


@Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.recycler_layout, parent, false);

    MyViewHolder vh = new MyViewHolder(view);
    return vh;
}


@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    String dayInit = days[position];
    String numberInit = numbers[position];
    Long positions = (long) position;

    System.out.println("Position: " + position);

    boolean isSelected = false;
    if(mSelectionTracker != null){
        if(mSelectionTracker.isSelected(positions)){
            isSelected = true;
        }
        holder.bind(position, dayInit, numberInit, isSelected);
    }
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    return days.length;
}

@Override
public long getItemId(int position) {
    return position;
}

SOLVED

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    String dayInit = days[position];
    String numberInit = numbers[position];
    Long id = getItemId(position);

    boolean isSelected = false;
    if(mSelectionTracker != null) {
        if (mSelectionTracker.isSelected(id)) {
            isSelected = true;
        }
    }

    System.out.println("Here: " + isSelected);
    holder.bind(position, id, dayInit, numberInit, isSelected);
}

@Override
public long getItemId(int position) {
    return position;
}

I retrieved position from getItemId and put that into my id variable (I used setHasStableIds). Click Listener isn't needed for this implementation. This is for the androidx recyclerview-selection library

Lastly I declared these in MyViewHolder:

scheduleDetails.position = position; scheduleDetails.identifier = key;
