我将使用recyclerview，我在列表中有10多个项目，我必须改变一个项目的文本颜色和背景布局，否则所有的项目颜色不变。请给我建议解决这个问题的正确方法。我将尝试在bindviewholder、viewholder和适配器单击项中更改颜色，但我成功更改了颜色，但没有成功地将颜色更改回。
public class LoadVehicleTypeAdapter extends RecyclerView.Adapter<LoadVehicleTypeAdapter.CarTypesHolder> {
private List<TaxiTypeResponse.Message> CarTypesModelsList;
