此工程较BaiduLocationXML相比：
1.植入fragment，结合微信UI
2.在原本主界面的button textview textview 移植到Fragment1
3.增加网络判断，网络不通的情况下做另外处理
4.在网络通畅的情况下，将地址信息、天气信息存入xml(sharedpreferences)，
网络不通的情况下，将原先xml信息读出展现
fragment植入

weatherInfo = (TextView) rootView.findViewById(R.id.weather_info);
initializeListeners();
initialize();//注册广播
return rootView;
}

SharedPreferences:
//保存为xml部分
SharedPreferences perference =context.getSharedPreferences("result",context.MODE_WORLD_READABLE);//xml名为result
editor = perference.edit();
editor.putString("地址",addressStr);

//以上的put内容是保存在内容中，完成后利用commit提交
editor.commit();
//获取SharedPreferences
SharedPreferences perference = getActivity().getApplicationContext().getSharedPreferences("result",getActivity().getApplicationContext().MODE_PRIVATE);
//取得key为name的值，如果不存在，则返回空值
String addr = perference.getString("地址","");
//取得key为age的值，如果不存在，则返回0
String weather = perference.getString("天气信息","");
网络连通状态判断
//构造函数类型
public class NetworkStatus {
