一、概述

在github中搜索recyclerview关键字，点赞最多的就是（BaseRecyclerViewAdapterHelper）这个库，所以抽空写了个demo看下效果！

二、普通列表

这里写图片描述

FirstActivity.java

package com.czhappy.brvahdemo.activity;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;

import com.chad.library.adapter.base.BaseQuickAdapter;
import com.czhappy.brvahdemo.model.FirstData;
import com.czhappy.brvahdemo.R;
import com.czhappy.brvahdemo.adapter.FirstAdapter;
import com.czhappy.brvahdemo.utils.Utils;
import com.czhappy.brvahdemo.view.ItemDivider;

import java.util.ArrayList;
import java.util.List;

public class FirstActivity extends AppCompatActivity {

    private List<FirstData> mDataList;
    private RecyclerView mRecyclerView;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first);
        initView();
        initData();
        initAdapter();
    }

    private void initView() {
        mRecyclerView = (RecyclerView) findViewById(R.id.rv_list);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
        //添加分割线
        mRecyclerView.addItemDecoration(new ItemDivider().setDividerWith(Utils.dip2px(this, 0.5f)).setDividerColor(0xffdddddd));

    }

    @SuppressWarnings("unchecked")
    private void initAdapter() {
        final BaseQuickAdapter firstAdapter = new FirstAdapter(R.layout.item_first_list, mDataList);
        //firstAdapter.openLoadAnimation();
        firstAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
                mDataList.get(position).name = "更新--"+position;
                firstAdapter.setNewData(mDataList);
            }
        });

        mRecyclerView.setAdapter(firstAdapter);
    }

    private void initData() {
        mDataList = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            FirstData item = new FirstData();
            item.drawable = R.mipmap.ic_launcher;
            item.name = "张珊珊所所所所aaaaa343543543"+i;
            mDataList.add(item);
        }
    }
}

FirstAdapter.java

package com.czhappy.brvahdemo.adapter;

import com.chad.library.adapter.base.BaseQuickAdapter;
import com.chad.library.adapter.base.BaseViewHolder;
import com.czhappy.brvahdemo.model.FirstData;
import com.czhappy.brvahdemo.R;

import java.util.List;

/**

public class FirstAdapter extends BaseQuickAdapter<FirstData, BaseViewHolder> {

    public FirstAdapter(int layoutResId, List<FirstData> list) {
        super(layoutResId, list);
    }

    @Override
    protected void convert(BaseViewHolder helper, FirstData item) {

        helper.setText(R.id.name_tv, item.name);
        helper.setImageResource(R.id.image_iv, item.drawable);
    }
}

activity_first.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fadingEdge="none"/>

</LinearLayout>

item_first_list.xml

<?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"
    android:orientation="horizontal"
    android:gravity="center_vertical"
    android:padding="10dp">


    <ImageView

        android:layout_marginLeft="10dp"
        android:textColor="#333333"
        android:textSize="16sp" />
</LinearLayout>

三、下拉刷新、上拉加载

这里写图片描述

SecondActivity.java

import java.util.ArrayList;
import java.util.List;

    private int page = 0;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {

    }

    private void initData() {

            FirstData item = new FirstData();

        }, 2000);
