详细说明： 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 2.MainActivitypackage 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 listData; private int refreshTime = 0; Override protected 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() { Override public 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 } Override public 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(); mAdapter = new MyAdapter(listData); for(int i = 0; i < 15 ;i ){ listData.add("item" i); } mRecyclerView.setAdapter(mAdapter); } Override public 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; } Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.
