使用 AS 自带的依赖管理工具加入RecyclerView的依赖,注意和和编译版本号一致

布局管理器用于显示列表展示样式

         //找到这个Listview
        mRecyclerView = (RecyclerView) findViewById(R.id.main_recylist);
        //设置线性管理器
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));

        myAdapter = new MyAdapter(mDataList);
        mRecyclerView.setAdapter(myAdapter);

public class ViewHolder extends RecyclerView.ViewHolder {

        private TextView mTvTitle;

        public ViewHolder(View itemView) {
            super(itemView);
            mTvTitle = (TextView) itemView.findViewById(R.id.item_tv);

        }

    }

也就是每一项展示效果

 @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.main_listview, parent, false));
    }

根据 position 来定位列表项

public void onBindViewHolder(ViewHolder holder, int position) {

        //获取这个TextView

        TextView tv= holder.mTvTitle;

        tv.setText(mDataList.get(position));
    }

 @Override
    public int getItemCount() {
        // 返回数据集合大小
        return mDataList == null ? 0 : mDataList.size();
    }

private List mDataList;

    public MyAdapter(List list) {
        mDataList = list;
    }
