基于百度定位及天气获取的DEMO +fragment+sharedpreference

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

public class Fragment1 extends Fragment {

        weatherInfo = (TextView) rootView.findViewById(R.id.weather_info);
        initializeListeners();
        initialize();//注册广播
        return rootView;
    }
     @Override
        public void onDestroyView() {
           getActivity().unregisterReceiver(broadcastReceiver);  //注销广播
           super.onDestroyView();
        }

public class MainActivity extends FragmentActivity {

                        .getLayoutParams();

                if (currentPage == 0 && arg0 == 0) { // 0->1移动(第一页到第二页)

    }

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);
        editor.putString("天气信息",result);
        //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 {
    public boolean netStatus = false;

    public NetworkStatus(Context context) {
        try {
            ConnectivityManager connectManager = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo activeNetworkInfo = connectManager
                    .getActiveNetworkInfo();
            if (activeNetworkInfo != null) {
                if (activeNetworkInfo.isAvailable()
                        && activeNetworkInfo.isConnected()) {
                    netStatus = true;
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

//boolean类型
public class NetworkStatus {
    public boolean netStatus = false;
    public NetworkStatus(Context context) {
   ConnectivityManager con=(ConnectivityManager)context.getSystemService   (Activity.CONNECTIVITY_SERVICE);
    boolean wifi=con.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnectedOrConnecting();
    boolean internet=con.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).isConnectedOrConnecting();
    if(internet){
        //执行相关操作
        netStatus=true;
        Toast.makeText(context,
                "当前移动网络已连接！", Toast.LENGTH_LONG)
                .show();
    }else if(wifi){
        netStatus=true;
        Toast.makeText(context,

                .show();
    } else
    {
        Toast.makeText(context,
                 "亲，网络连了么？", Toast.LENGTH_LONG)
