1. 先看一下效果圖

2. 主要實現(xiàn)思路

2.1. 適配器定義全局變量(點擊的下標)

private int selectNum = -1;

2.2. 點擊事件得到條目的position

holder.llItem.setOnClickListener(new View.OnClickListener() {
            @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
            @Override
            public void onClick(View view) {
               if (listener != null) {
                    listener.onItemClickListener(position);
                }
                //點擊進行重新賦值
                selectNum = position;
                //刷新適配器
                notifyDataSetChanged();
            }
        });

2.3. 對全局定義的變量進行重新賦值 之后刷新適配器

3. 代碼部分

 @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position) {
        holder.mTvTese.setText("測試數(shù)據(jù)" + mTestBeans.get(position).getId());
        if (position == selectNum) {
            holder.mTvTese.setTextColor(context.getResources().getColor(R.color.colorTest));
            holder.mIvTest.setImageDrawable(context.getDrawable(R.drawable.image_select));
        } else {
            holder.mTvTese.setTextColor(context.getResources().getColor(R.color.color8888));
            holder.mIvTest.setImageDrawable(context.getDrawable(R.drawable.image_noselect));
        }

        holder.llItem.setOnClickListener(new View.OnClickListener() {
            @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
            @Override
            public void onClick(View view) {
               if (listener != null) {
                    listener.onItemClickListener(position);
                }
                selectNum = position;
                notifyDataSetChanged();
            }
        });
    }
