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);
}
}
