RecyclerView技术栈
Android RecyclerView 使用完全解析 体验艺术般的控件
[Android]使用RecyclerView替代ListView（一）

一、

RecyclerAdapter.java:

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import java.util.List;

    }

    public OnItemClickListener itemClickListener;

    public void setOnItemClickListener(
            OnItemClickListener itemClickListener) {
        this.itemClickListener = itemClickListener;
    }

    public interface OnItemClickListener {
        void onItemClick(View view, int position);
    }

    public class ViewHolder extends RecyclerView.ViewHolder
            implements View.OnClickListener {

        public TextView textView;

        public ViewHolder(View itemView) {
            super(itemView);
            textView = (TextView) itemView;
            textView.setOnClickListener(this);
        }

        // 通过接口回调来实现RecyclerView的点击事件
        @Override
        public void onClick(View v) {
            if (itemClickListener != null) {
                itemClickListener.onItemClick(v, getPosition());
            }
        }
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        // 将布局转化为View并传递给RecyclerView封装好的ViewHolder
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(
                R.layout.rc_item, viewGroup, false);
        return new ViewHolder(v);
    }

    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int i) {
        // 建立起ViewHolder中视图与数据的关联
        viewHolder.textView.setText(mData.get(i) + i);
    }

    @Override
    public int getItemCount() {
        return mData.size();
