json文件如下:
将获取到的json数据转化为String形式
OkHttpClient client = new OkHttpClient(); Request request = new Request.Builder() .url("http://10.0.2.2/get_data.json") .build(); Response response =client.newCall(request).execute(); String responseData = response.body().string();
以JSONObject方式解析:将获取的字符串转化为json数组,然后循环遍历这个数组。
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 version = jsonObject.getString("version"); String name = jsonObject.getString("name"); Log.i("JSONObject", "id is: "+id); Log.i("JSONObject", "version is: "+version); Log.i("JSONObject", "name is: "+name); } }catch (Exception e){ e.printStackTrace(); } }
以GSON方式:
首先依据json文件的形式建相应的类:
public class App { private String id; private String version; private String name; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getVersion() { return version; } public void setVersion(String version) { this.version = version; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
然后,新建一个Gson对象,利用TypeToken的方式将Data转成一个List并把这个List传入fromJson方法
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.i("GSON", "id is: "+app.getId()); Log.i("GSON", "version is: "+app.getVersion()); Log.i("GSON", "name is: "+app.getName()); } }
