android 解析数据之Gson2
这篇文章主要的目的是补充上一篇文章的，这次解析的是更加复杂的数据
QIYBean（这是根据Json代码使用GsonFormat自动生成的类）很尴尬由于数据复杂所以生成的代码有点长

GsonUtil（用来解析Json数据）
package com.chuanxidemo.shaoxin.mymusic; import com.google.gson.Gson; import com.google.gson.reflect.TypeToken; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import java.util.ArrayList; import java.util.List; /** * Created by shaoxin on 2017/3/1. */ public class GsonUtil { public static BufferedReader bufferedReader; public static StringBuffer stringBuffer; // 将Json数据解析成相应的映射对象 public static <T> T parseJsonWithGson(String jsonData, Class<T> type) { Gson goson = new Gson(); T result = goson.fromJson(jsonData, type); return result; } // 将Json数组解析成相应的映射对象列表 public static <T> List<T> parseJsonArrayWithGson(String jsonData, Class<T> cls) { Gson gson = new Gson(); List<T> result = new ArrayList<>(); result = gson.fromJson(jsonData, new TypeToken<List<T>>() { }.getType()); return result; } // 根据json数据地址获取数据 public static String getData(String jsonURL) { try { stringBuffer = new StringBuffer(); URL url = new URL(jsonURL);//json地址 HttpURLConnection connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("GET");//使用get方法接收 InputStream inputStream = connection.getInputStream();//得到一个输入流 bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTf-8")); String sread = null; while ((sread = bufferedReader.readLine()) != null) { stringBuffer.append(sread); stringBuffer.append("\r\n"); } // Log.i("msg", "onClick: " + stringBuffer.toString()); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return stringBuffer.toString(); } }
GetGsonData（获取其中的数据）

showdata.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <TextView android:id="@+id/txt" android:layout_width="match_parent" android:layout_height="wrap_content" /> <Button android:id="@+id/get_data" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="获取数据"/> </LinearLayout>
以上是完整代码，记得添加Gson包和添加权限
