JSON格式解析

样例JSON格式

[
    {"id":"5", "version":"1", "name":"Clash of Clans"},
    {"id":"6", "version":"2", "name":"Boom Beach"},
    {"id":"5", "version":"1", "name":"Okey Google"}
]

1.使用JsonObject解析

还是以上文xml解析的activity为基础，将parseXml方法替换成parseJsonWithJSONObject方法

    private void parseJsonWithJSONObject(String responseString) {
        try {
            JSONArray array = new JSONArray(responseString);
            for (int i = 0; i < array.length(); i++) {
                JSONObject jObject = array.getJSONObject(i);
                String id = jObject.getString("id");
                String name = jObject.getString("name");
                String version = jObject.getString("version");
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

2.使用Gson解析

Gson是谷歌提供的用于解析Json数据的开源库，可以以十分简单的方式来解析Json数据

基本用法

        Gson gson = new Gson(); //create a new Gson object;
        AppBean apps = gson.fromJson(responseString, AppBean.class); //parse an Json Object
        List appList = gson.fromJson(responseString
                , new TypeToken>(){}.getType());  //parse an Json array

Sample Code

    private void parseJsonWithGson(String responseString) {
        Gson gson = new Gson();
        //parse an Json array
        List appList = gson.fromJson(responseString, new TypeToken>(){}.getType());
        for(AppBean app : appList) {
            //do whatever you want with data
            Log.i("lyh", app.toString());
        }
    }
