android中使用开源项目做出上拉、下拉刷新功能

在github网站，下载xlistview项目，导入Eclipse转成库文件，在新建项目里，添加此库。

在布局中使用自定义xlistview控件

<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" >    <me.maxwin.view.XListView        android:id="@+id/xListView"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:cacheColorHint="#00000000" >    </me.maxwin.view.XListView></RelativeLayout>

代码如下：

public class MainActivity extends Activity implements IXListViewListener{    private XListView mListview;    ArrayList<String> mlist = new ArrayList<String>();    private ArrayAdapter<String> mAdapter;    private Handler mhandler;    @Override    protected void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        mhandler = new Handler();        mListview = (XListView) findViewById(R.id.xListView);        mListview.setPullRefreshEnable(true);//设置下拉刷新        mListview.setXListViewListener(this);//设置监听事件，重写两个方法        mListview.setPullLoadEnable(true);//设置上拉刷新        mAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, mlist);        for (int i = 0; i < 20; i++)        {            mlist.add("data" + i);        }        mListview.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.main, menu);        return true;    }    @Override    public void onRefresh()    {        mhandler.postDelayed(new Runnable()        {                          @Override            public void run()            {                mlist.add(0, new Date().toString());                mAdapter.notifyDataSetChanged();                mListview.stopRefresh();//完成                              }        }, 2000);    }    @Override    public void onLoadMore()    {        mhandler.postDelayed(new Runnable()        {                          @Override            public void run()            {                mlist.add(new Date().toString());                mAdapter.notifyDataSetChanged();                mListview.stopLoadMore();            }        }, 2000);    }}
