直接上代码，代码有注释：
public class TestForListviewActivity extends Activity implements
OnScrollListener {
private ListView mListview = null;
private View mFooterView;
private PaginationAdapter mAdapter;
private Handler handler=new Handler();
private boolean isLoading;//表示是否正在加载
private final int MAX_COUNT=35;//表示服务器上总共有MAX_COUNT条数据
private final int EACH_COUNT=10;//表示每次加载的条数
@Override

mFooterView = getLayoutInflater().inflate(R.layout.loadmore, null);
mListview = (ListView) findViewById(R.id.listview);
mListview.addFooterView(mFooterView);// 设置列表底部视图
List news=new ArrayList();
mAdapter = new PaginationAdapter(news);;
mListview.setAdapter(mAdapter);
//设置setOnScrollListener会自动调用onscroll方法。
mListview.setOnScrollListener(this);
}
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if (firstVisibleItem+visibleItemCount==totalItemCount&&!isLoading) {
//isLoading = true 表示正在加载，加载完毕设置isLoading =false；
isLoading = true;
//如果服务端还有数据，则继续加载更多，否则隐藏底部的加载更多
