Question

我正在使用回收站视图，并且根据项目要求实现了此功能。但是在我的情况下，项目已突出显示，但不再突出显示。我对在何处单击该项目以创建单击功能以及如何取消突出显示该项目感到困惑。请为我建议解决代码的正确方法

public class LoadVehicleTypeAdapter  extends RecyclerView.Adapter<LoadVehicleTypeAdapter.CarTypesHolder> {

private List<TaxiTypeResponse.Message> CarTypesModelsList;
private Context mContext;
VehicleTypeView vehicleTypeView;
setOnitemclick listener;
private SparseBooleanArray selectedItems = new SparseBooleanArray();
int I=-1;
public class CarTypesHolder extends RecyclerView.ViewHolder {
    public CustomTextView mCarType;
    public CircleImageView mCarTypeImage;
    LinearLayout llRoot;
    CardView cardView;
    private SparseBooleanArray selectedItems = new SparseBooleanArray();
    setOnitemclick listener;

    public CarTypesHolder(final View view) {
        super(view);
        mCarType = (CustomTextView) view.findViewById(R.id.frag_cartypes_inflated_name);
        mCarTypeImage = (CircleImageView) view.findViewById(R.id.frag_cartype_inflated_frameImage);
        llRoot = (LinearLayout)view.findViewById(R.id.root1);
        cardView=(CardView) view.findViewById(R.id.cardf);


    }

    public void setOnItemClickListner(setOnitemclick listener12) {
        listener=listener12;
    }

}
public void setOnItemClickListner(setOnitemclick listener12) {
    listener=listener12;
}


public LoadVehicleTypeAdapter(Context context, List<TaxiTypeResponse.Message> CarTypesModelsList, VehicleTypeView vehicleTypeView) {
    this.CarTypesModelsList = CarTypesModelsList;
    mContext = context;
    this.vehicleTypeView = vehicleTypeView;
}


@Override

    View itemView;
    itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.frag_cartype_inflated_view, parent, false);
    return new CarTypesHolder(itemView);
}

@SuppressLint("ResourceType")
@Override
public void onBindViewHolder(final CarTypesHolder holder, final int position) {

    TaxiTypeResponse.Message carTypesModel = CarTypesModelsList.get(position);
    I=CarTypesModelsList.get(position).getID();

    holder.setOnItemClickListner(listener);

    holder. llRoot.setOnClickListener(new View.OnClickListener() {

     }

     void ImageClickfade(int position, String Name,String Description,int id);

我将用来更新gradle

maven { url "https://maven.google.com" }

并更新代码

public class LoadVehicleTypeAdapter  extends RecyclerView.Adapter<LoadVehicleTypeAdapter.CarTypesHolder> {

private List<TaxiTypeResponse.Message> CarTypesModelsList;

    public void setOnItemClickListner(setOnitemclick listener)
    {
        this.listener=listener;
    }
