上拉加载下拉刷新

需要关联第三方包XListView

导入三个包

**

package com.example.xlistviewtest;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.List;
import org.com.cctest.view.XListView;
import org.com.cctest.view.XListView.IXListViewListener;
import android.app.Activity;
import android.os.Bundle;
import android.text.format.DateFormat;
import android.widget.ArrayAdapter;
public class MainActivity extends Activity {
private List<String> list;
int j;
private ArrayAdapter<String> arrayAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setData();
final XListView xListView = (XListView) findViewById(R.id.xListView);
属性：
// 激活加载更多
xListView.setPullLoadEnable(true);
// 激活下拉刷新
xListView.setPullRefreshEnable(true);
// 设置xlistView上拉加载下拉刷新的监听
xListView.setXListViewListener(new IXListViewListener() {
@Override
// 下拉刷新的回调方法
public void onRefresh() {
// 下拉刷新,应该展示最新数据,所以清空集合
list.clear();
arrayAdapter.notifyDataSetChanged();
//设置刷新时间
xListView.setRefreshTime(dateFormat());
//停止加载更多
xListView.stopLoadMore();
//停止刷新
xListView.stopRefresh();
}
@Override
// //上拉加载的回调方法
public void onLoadMore() {
arrayAdapter.notifyDataSetChanged();
//停止加载更多
xListView.stopLoadMore();
//停止刷新
xListView.stopRefresh();
}
});
arrayAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, list);
xListView.setAdapter(arrayAdapter);
}



/**
* 格式化毫秒值
*
* @return
*/
private String dateFormat() {
long currentTimeMillis = System.currentTimeMillis();
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
String format = dateFormat.format(currentTimeMillis);
return format;
}
