Question

我有JSON响应，它在JSON数组中有JSON数组。请告诉我如何解析它。请告诉我它是多个JSON数组解析的最佳示例。我有所有的领域动态，所以开发人员给我这种回应。提前致谢。

    {
"products": [
    {
      "id": "14",
      "cat_id": [

Answer 1

如何解析JSON及其中的内容遵循here。

Answer 2

解析json：

JSONObject jsonObj = new JSONObject(jsonStr);// your string.
JSONArray jsonArray = jsonObj.getJSONArray("products");


for(int i=0; i < jsonArray.length(); i++){
       JSONObject prod = jsonArray.getJSONObject(i);
       String id = prod.getString("id");

       // and so on ...you can parse the entire json using either array or object

}

使用try catch环绕异常....

Answer 3

首先，如果您的JSON有效，您需要验证。 Json Validator

如果你发现这个有效，那么

try { JSONObject  jsonRootObject = new JSONObject(strJson);
         //Get the instance of JSONArray that contains JSONObjects
         JSONArray jsonArray = jsonRootObject.optJSONArray("products");   
         //Iterate the jsonArray and print the info of JSONObjects
         for(int i=0; i < jsonArray.length(); i++){
            JSONObject jsonObject = jsonArray.getJSONObject(i);
            int id = Integer.parseInt(jsonObject.optString("id").toString());
            String name = jsonObject.optString("name").toString();
            float product_image = Float.parseFloat(jsonObject.optString("product_image").toString());
         JSONArray cat_idArray = jsonRootObject.optJSONArray("cat_id");    
         for(int i=0; i < cat_idArray.length(); i++){
        //Here you can get other values
           }
            data += "Node"+i+" : \n id= "+ id +" \n Name= "+ name +" \n Salary= "+ salary +" \n ";
         }
         output.setText(data);
      } catch (JSONException e) {e.printStackTrace();}

Json解析就是要理解对象的层次结构＆＃39; {}＆＃39;和阵列＆＃39; []＆＃39; 。您可以查看以下链接以了解它。 How to parse this nested JSON array in android 或http://www.coderzheaven.com/2011/06/10/complex-json-string-parsing-in-android/
