使用android自带的SwipeRefreshLayout实现下拉刷新

效果图：
MainActivity.java
<span style="font-family:Arial;">package com.hnpolice.luoxiaoke.swiperefreshlayout;import android.os.Bundle;import android.os.Handler;import android.support.v4.widget.SwipeRefreshLayout;import android.support.v7.app.AppCompatActivity;import android.widget.ArrayAdapter;import android.widget.ListView;import java.util.ArrayList;import java.util.List;import butterknife.ButterKnife;import butterknife.InjectView;public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {    @InjectView(R.id.list_view)    ListView listView;    @InjectView(R.id.refresh_layout)    SwipeRefreshLayout refreshLayout;    //下拉刷新状态    private static final int REFRESH_COMPLETE = 110;    private List<String> datas = new ArrayList<>();    private ArrayAdapter adapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.inject(this);        // Set the listener to be notified when a refresh is triggered via the swipe gesture.        refreshLayout.setOnRefreshListener(this);        // Set the colors used in the progress animation.        refreshLayout.setColorSchemeResources(R.color.color_blue, R.color.color_green, R.color.color_red);        for (int i = 0; i < 5; i++) {            datas.add("item" + i);        }        adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, datas);        listView.setAdapter(adapter);    }    @Override    public void onRefresh() {        //2000  ： 2s后执行        mHandler.sendEmptyMessageDelayed(REFRESH_COMPLETE, 2000);    }    private Handler mHandler = new Handler() {        public void handleMessage(android.os.Message msg) {            switch (msg.what) {                case REFRESH_COMPLETE:                    datas.add("added");                    adapter.notifyDataSetChanged();                    refreshLayout.setRefreshing(false);                    break;            }        }    };}</span><span style="font-family:Consolas;"></span>
