介绍:
一个实现了下拉刷新,滚动到底部加载更多以及添加header功能的的RecyclerView。使用方式和RecyclerView完全一致,不需要额外的layout,不需要写特殊的adater。 加载效果内置了AVLoadingIndicatorView上的所有效果,可以根据需要指定。

项目地址:https://github.com/jianghejie/XRecyclerView

效果:


使用:

xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context=".MainActivity"><com.jcodecraeer.xrecyclerview.XRecyclerViewandroid:id="@+id/recyclerview"android:layout_width="fill_parent"android:layout_height="fill_parent" /></RelativeLayout>

2.MainActivity

package com.example.xrecyclerview; import android.os.Bundle;import android.os.Handler;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.LinearLayoutManager;import android.view.LayoutInflater;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.ViewGroup;import com.jcodecraeer.xrecyclerview.ProgressStyle;import com.jcodecraeer.xrecyclerview.XRecyclerView;import java.util.ArrayList; public class MainActivity extends AppCompatActivity {private XRecyclerView mRecyclerView;private MyAdapter mAdapter;private ArrayList<String> listData;private int refreshTime = 0;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);mRecyclerView = (XRecyclerView)this.findViewById(R.id.recyclerview);LinearLayoutManager layoutManager = new LinearLayoutManager(this);layoutManager.setOrientation(LinearLayoutManager.VERTICAL);mRecyclerView.setLayoutManager(layoutManager);mRecyclerView.setRefreshProgressStyle(ProgressStyle.BallSpinFadeLoader);mRecyclerView.setLaodingMoreProgressStyle(ProgressStyle.Pacman);mRecyclerView.setArrowImageView(R.drawable.iconfont_downgrey);View header = LayoutInflater.from(this).inflate(R.layout.recyclerview_header, (ViewGroup)findViewById(android.R.id.content),false);mRecyclerView.addHeaderView(header);mRecyclerView.setLoadingListener(new XRecyclerView.LoadingListener() {@Overridepublic void onRefresh() {refreshTime ++;new Handler().postDelayed(new Runnable(){public void run() {listData.clear();for(int i = 0; i < 15 ;i++){listData.add("item" + i + "after " + refreshTime + " times of refresh");}mAdapter.notifyDataSetChanged();mRecyclerView.refreshComplete();}}, 3000);   //refresh data here} @Overridepublic void onLoadMore() {new Handler().postDelayed(new Runnable(){public void run() {for(int i = 0; i < 15 ;i++){listData.add("item" + (i + listData.size()) );}mAdapter.notifyDataSetChanged();mRecyclerView.loadMoreComplete();}}, 3000); }}); listData = new ArrayList<String>();mAdapter = new MyAdapter(listData);for(int i = 0; i < 15 ;i++){listData.add("item" + i);}mRecyclerView.setAdapter(mAdapter);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.menu_main, menu);return true;} @Overridepublic boolean onOptionsItemSelected(MenuItem item) {// Handle action bar item clicks here. The action bar will// automatically handle clicks on the Home/Up button, so long// as you specify a parent activity in AndroidManifest.xml.int id = item.getItemId();//noinspection SimplifiableIfStatementif (id == R.id.action_settings) {return true;} return super.onOptionsItemSelected(item);}  }

3. adapter

package com.example.xrecyclerview;import android.support.v7.widget.RecyclerView;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;import java.util.ArrayList;/*** Created by jianghejie on 15/11/26.*/public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {public ArrayList<String> datas = null;public MyAdapter(ArrayList<String> datas) {this.datas = datas;}//创建新View,被LayoutManager所调用@Overridepublic ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.item,viewGroup,false);ViewHolder vh = new ViewHolder(view);return vh;}//将数据与界面进行绑定的操作@Overridepublic void onBindViewHolder(ViewHolder viewHolder, int position) {viewHolder.mTextView.setText(datas.get(position));}//获取数据的数量@Overridepublic int getItemCount() {return datas.size();}//自定义的ViewHolder,持有每个Item的的所有界面元素public static class ViewHolder extends RecyclerView.ViewHolder {public TextView mTextView;public ViewHolder(View view){super(view);mTextView = (TextView) view.findViewById(R.id.text);}}
