RV点击条目改变字体颜色（数据驱动UI）

1对应集合实体类增加是否点击的属性

 public static class ChildrenListDTO {
    
    
            private boolean isClick = false;

            public boolean isClick() {
    
    
                return isClick;
            }

            public void setClick(boolean click) {
    
    
                isClick = click;
            }

2点击的时候改变标志位状态，此时唤醒适配器；注意 recyClassAdapter1.notifyDataSetChanged();

 childrenListThree.get(tag).setClick(true);
  recyClassAdapter1.notifyDataSetChanged();

3适配中添加控件颜色改变的判断；注意 holder.tv.setTextColor(context.getColor(R.color.blue));

  public void onBindViewHolder(ViewHolder holder, int position) {
    
    
//        int newPos=position%datas.size();


        holder.tv.setText(datas.get(position).getClassificationName());
        Log.e("wy", "73 onBindViewHolder  : " + datas.get(position).isClick());
        if (datas.get(position).isClick()) {
    
    
            datas.get(position).setClick(false);
            holder.tv.setTextColor(context.getColor(R.color.blue));
        } else {
    
    
            holder.tv.setTextColor(context.getColor(R.color.black));
        }
