在主activity中,设置一些属性
package com.example.listviewshangxia;
import java.util.ArrayList;

import java.util.Map;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

import android.widget.AdapterView.OnItemClickListener;
import android.widget.Toast;
import com.example.listviewshangxia.XListView.IXListViewListener;
public class MainActivity extends Activity implements IXListViewListener {

/** 下拉刷新,上拉加载 */
dlist = new ArrayList<HashMap<String, Object>>();
mListView = (XListView) findViewById(R.id.techan_xListView);// 这个listview是在这个layout里面
mListView.setPullLoadEnable(true);// 设置让它上拉,FALSE为不让上拉,便不加载更多数据
mAdapter1 = new SimpleAdapter(MainActivity.this, getData(),

// 刷新

// 加载更多
@Override

}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if(keyCode==KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0){

}
return false;
}
}
设置xml
