  }
}
]
 }
}

我需要获取“屏幕快照”标签数组。 这是我的代码

JSONArray responseArray = jsonObj.getJSONArray("body");
for (int i = 0; i < responseArray.length(); i++) {
JSONArray applicationsArray = c.getJSONArray("applications");
                for (int k = 0; k < applicationsArray.length(); k++) {
                    JSONObject e = applicationsArray.getJSONObject(k);

                    JSONArray playstore = e.getJSONArray("playstore");
                    for (int l = 0; l < playstore.length(); l++) {
                        JSONObject f = playstore.getJSONObject(l);
                        Log.e("scren ",""+f.getString("screenshots"));
                        JSONArray screenshotArray = f.getJSONArray("screenshots");
                        Log.e("scren ",""+screenshotArray);
                    }
                }

Answer 1

jsonObj包含json值

    JSONObject data = jsonObj.getJSONObject("data");
    JSONArray applications = data.getJSONArray("applications");

     for (int k = 0; k < applications.length(); k++) {
         JSONObject playstore = applications[k].getJSONObject("playstore");
         JSONArray screenshots = playstore.getJSONArray("screenshots");
         for (int i = 0; i < screenshots.length(); i++) {
            Log.e("screenshot  ",""+screenshots[i]);
         }
     }

你可以这样尝试

Answer 2

假设您已经设置了android中json解析的所有先决条件。

我将转向如何解析此数据

if(response!=null){
            try {

                JSONObject jsonObject = new JSONObject(response);
                JSONObject data = jsonObject.getJSONObject("data");
                JSONArray jsonArray = jsonObject.optJSONArray("applications");
                for(int i=0; i<jsonArray.length(); i++){
                    jsonObject= jsonArray.getJSONObject(i);



                    JSONObject c = jsonArray.getJSONObject(i);

                    String app_name = c.getString("application_name");
                    String app_os = c.getString("application_os");
                    String app_downloads = c.getString("app_downloads");
                    String bundle = c.getString("bundle_id");


                    // playstore node is JSON Object
                    JSONObject playstore = c.getJSONObject("playstore");
                    String downloads = phone.getString("downloads");
                    String rating = phone.getString("rating");
                    String developer = phone.getString("developer");

                    // screenshots node is JSON Array
                    JSONArray screenshots = jsonObject.optJSONArray("screenshots");
                    for(int j=0; j<screenshots.length(); j++){
                        Log.e("screenshot  ",""+screenshots[i]);

                    }

                }

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

        }
