JSON 数据解析

json数据 http://emotionalronanyg.github.io/get_data.json

JSONObject 解析json数据

    //JSONObject  解析json数据    private void parseJsonWithJSONObject(String jsonData) {        try {            JSONArray jsonArray = new JSONArray(jsonData);            for (int i = 0;i<jsonArray.length();i++){                JSONObject jsonObject = jsonArray.getJSONObject(i);                String id = jsonObject.getString("id");                String name = jsonObject.getString("name");                String version = jsonObject.getString("version");                Log.d("MainActivity", "id :"+id+"\t\tname :"+name+"\t\tversion:"+version);            }        } catch (JSONException e) {            e.printStackTrace();        }    }

Gson 解析json数据

参考 https://github.com/EmotionalRonanyg/gson

依赖 compile ‘com.google.code.gson:gson:2.8.0’

    //Gson  解析json数据    private void parseJsonWithGson(String jsonData) {        Gson  gson = new Gson();        List<App> appList = gson.fromJson(jsonData,new TypeToken<List<App>>(){}.getType());        for (App app:appList){            Log.d("MainActivity---","id:"+app.getId()+"\t\tname:"+app.getName()+"\t\tversion: "+app.getVersion());        }    }

Http请求

参考 https://github.com/EmotionalRonanyg/okhttp

OkHttp 依赖 compile ‘com.squareup.okhttp3:okhttp:3.7.0’

   private void sendRequestWithOkHttp() {        //开启线程 发送网络请求        new Thread(new Runnable() {            @Override            public void run() {                try {                    OkHttpClient client = new OkHttpClient();                    Request request = new Request.Builder()                            //json数据                            .url("http://emotionalronanyg.github.io/get_data.json")                            .build();                    Response response = client.newCall(request).execute();                    String responseData = response.body().string();                    showResponse(responseData);                    //JSONObject 解析json                    parseJsonWithJSONObject(responseData);                    //Gson  解析json                    parseJsonWithGson(responseData);                } catch (IOException e) {                    e.printStackTrace();                }            }        }).start();//开启线程    }

APP 实体

public class App {    private String id;    private String name;    private String version;    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getVersion() {        return version;    }    public void setVersion(String version) {        this.version = version;    }}
