天气解析
前段时间做了一个天气类的解析，防止自己忘记了，特整理以下笔记。首先，接口用的是http://weather.51wnl.com/weatherinfo/GetMoreWeather?cityCode=101200105&weatherType=0 这个，需要更多的接口看这个http://www.eoeandroid.com/thread-333874-1-1.html，里面整理了几个Json数据的接口，很好用。是我百度得到的...。
其次，开始实施：
先看结构：
我这个解析是在我的一个应用里做的，解析的数据展示在fragment里面，所以用的是fragment。
继续：下面是贴代码
1、回调接口，好拿数据
package http;
public interface HttpCallbackListener {
void onFinish(String response);
void onError(Exception e);
}
2、网络请求类，返回json数据
package http;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import android.os.Looper;
import android.util.Log;
import android.widget.Toast;
public class HttpUtils {
public static void sendHttpRequest(final String address,
final HttpCallbackListener listener) {
new Thread(new Runnable() {
@Override
public void run() {
Looper.prepare();
HttpURLConnection connection = null;
try {
URL url = new URL(address);
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(8000);
connection.setReadTimeout(8000);
InputStream in = connection.getInputStream();
BufferedReader reader = new BufferedReader(
new InputStreamReader(in));
StringBuilder response = new StringBuilder();
String line;
while ((line = reader.readLine()) != null) {
response.append(line);
}
if (listener != null) {
// 回调onFinish()方法
listener.onFinish(response.toString());
Log.i("HttpUtils", "-----"+response.toString());
}
} catch (Exception e) {
if (listener != null) {
// 回调onError()方法
listener.onError(e);
}
} finally {
if (connection != null) {
connection.disconnect();
}
}
Looper.loop();
}
}).start();
}
}3、天气的实体类
package http;
public class Weather {
public String city;
public String tem;
public String wea;
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public String getTem() {
return tem;
}
public void setTem(String tem) {
this.tem = tem;
}
public String getWea() {
return wea;
}
public void setWea(String wea) {
this.wea = wea;
}
@Override
public String toString() {
return "Weather [city=" + city + ", tem=" + tem + ", wea=" + wea + "]";
}
}
4、json数据解析类，本次实现的的方式是把获取到的数据存入到本地，采用sharedpreference的存储方式。
package http;
import org.json.JSONException;
import org.json.JSONObject;
import android.content.Context;
import android.content.SharedPreferences;
import android.preference.PreferenceManager;
import android.util.Log;
public class Utility {
/**
* 解析服务器返回的json数据
* @param context
* @param response
*/
public static void handleWeatherResponse(Context context,String response){
Log.i("Utility", "-------handleWeatherResponse+运行到这里");
try {
JSONObject jsonObject =new JSONObject(response);
JSONObject weatherInfo =jsonObject.getJSONObject("weatherInfo");
String city =weatherInfo.getString("city");
String tem =weatherInfo.getString("temp1");
String weather =weatherInfo.getString("weather");
Log.i("Utility", "--------"+city+tem+weather);
SharedPreferences.Editor edit =PreferenceManager.getDefaultSharedPreferences(context).edit();
// SharedPreferences.Editor edit = getSharedPreferences("data",context.MODE_PRIVATE).edit();
edit.putString("city", city);
edit.putString("tem",tem);
edit.putString("weather", weather);
SharedPreferences pres =PreferenceManager.getDefaultSharedPreferences(context);
String city2 =pres.getString("city", "");
Log.i("MainActivity","-----------写入数据===此时获取到的city数据是："+city);
edit.commit();
} catch (Exception e) {
e.printStackTrace();
}
}
}
package http;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
