RecyclerView

添加依赖：

compile 'com.android.support:recyclerview-v7:26.1.0'

MainActivity类：

package com.example.myapplication;

import android.graphics.drawable.Drawable;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.DividerItemDecoration;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.OrientationHelper;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.StaggeredGridLayoutManager;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
private RecyclerView recyclerView;
    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //查找组件
        recyclerView = (RecyclerView) findViewById(R.id.myrecy);
        final MyAdapter myAdapter=new MyAdapter(MainActivity.this);
        //设置条目点击
        myAdapter.setOnClickListener(new OnRecyclerClick() {
            //两个方法onItemClick、onItemLongClick实现点击和长点击两种状态
            @Override
            public void onItemClick(View itemView, int position) {
                Toast.makeText(MainActivity.this,position+"点击了",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onItemLongClick(View itemView, int position) {
                myAdapter.deleteItem(position);
                Toast.makeText(MainActivity.this,position+"长点击了--删除",Toast.LENGTH_SHORT).show();
            }
        });
        recyclerView.setAdapter(myAdapter);
        //设置布局管理器(LinearLayoutManager、GridLayoutManager、)，告诉recyclerview每一个item的位置怎么布局；
        //listview效果
        recyclerView.setLayoutManager(new LinearLayoutManager(MainActivity.this));
        //gridview效果,GridLayoutManager第二个参数代表多少列或行
        //recyclerView.setLayoutManager(new GridLayoutManager(MainActivity.this,6));
        //瀑布流效果，spancount代表几条瀑布流；第二个参数代表瀑布流的流向，水平和垂直两种方向
        //recyclerView.setLayoutManager(new StaggeredGridLayoutManager(6,OrientationHelper.HORIZONTAL));
        //设置VERTICAL分割线
        DividerItemDecoration decoration = new DividerItemDecoration(MainActivity.this, OrientationHelper.VERTICAL);
        //把分割线用张图来设置
       //Drawable drawable = getDrawable(R.mipmap.ic_launcher);
        //把分割线设置给recyclerView
        recyclerView.addItemDecoration(decoration);


    }
}

MyAdapter类：

package com.example.myapplication;

import android.content.Context;
import android.net.sip.SipSession;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import java.util.ArrayList;

/**
 * 
 */

public class MyAdapter extends RecyclerView.Adapter<MyViewHolder>{
    private Context context;
    private ArrayList<String> data=new ArrayList<String>();
    public MyAdapter(Context context){
        this.context=context;
        for (int i=0;i<20;i++){
            if (i%3==0){
                data.add("王屋山下的传说"+i);
            }else {
                data.add("南派三书"+i);
            }
        }
    }
    //删除对应位置的条目数据
    public  void deleteItem(int position){
        data.remove(position);
        //刷新全局
        //notifyDataSetChanged();
        //刷新删除的此条目
        notifyItemRemoved(position);

    }

    //三个重要的方法onCreateViewHolder、onBindViewHolder、getItemCount
    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //通过布局文件创建item的父view，返回viewholder
        View view= LayoutInflater.from(context).inflate(R.layout.item,parent,false);
        final MyViewHolder holder=new MyViewHolder(view);
        //条目点击事件设置
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //调用listener,点击条目
                listener.onItemClick(view,holder.getLayoutPosition());

            }
        });
        //条目长摁点击事件设置
        view.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View view) {
                //调用listener,长点击条目
                listener.onItemLongClick(view,holder.getLayoutPosition());
                //防止点击冲突（长点击时出现点击和长点击双重效果），把默认返回值false设置为true;
                return true;
            }
        });
        //返回holder
        return holder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        //给item赋值
        holder.textView.setText(data.get(position));
    }

    @Override
    public int getItemCount() {

        return data.size();
    }
    public OnRecyclerClick listener;
    //设置点击事件，在activity使用adapter调用
   public void setOnClickListener(OnRecyclerClick clickListener){
       //OnRecyclerClick的对象赋给listener
        this.listener=clickListener;
    }


}

MyViewHolder类：

package com.example.myapplication;

import android.support.v7.widget.RecyclerView;
import android.view.View;
import android.widget.TextView;

/**
 * 
 */

public class MyViewHolder extends RecyclerView.ViewHolder{
    public TextView textView;
    public MyViewHolder(View itemView) {
        super(itemView);
        //itemView代表布局文件的父view
        textView = (TextView) itemView.findViewById(R.id.tv);
    }
}


package com.example.myapplication;

import android.view.View;

/**
 * 
 */
//创建接口
public interface OnRecyclerClick {
    //条目点击方法
    void onItemClick(View itemView,int position);
    //条目长摁点击方法
    void onItemLongClick(View itemView,int position);
}

xml（设置recylerView的id）:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.myapplication.MainActivity">

    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/myrecy">

    </android.support.v7.widget.RecyclerView>
</android.support.constraint.ConstraintLayout>

xml(条目布局):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/tv"
    android:padding="10dp"/>
</LinearLayout>

style类（values里面的）：

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:listDivider">@mipmap/ic_launcher</item>

    </style>
