Question

我有这样的json响应：

array (
  'status' => 'OK',
  'categories' => 
  array (
    'Sepeda' => 
    array (
      83 => 'Sepeda MTB',
      'Fullbike' => 
      array (
        370 => 'MTB',
        371 => 'Roadbike',
        374 => 'Fixie',
        375 => 'Sepeda Lipat',
        378 => 'City Bike',
        380 => 'BMX',
        382 => 'Onthel',
      ),
      84 => 'Sepeda Lipat',
      'Frame' => 
      array (
        372 => 'MTB',
        373 => 'Roadbike',
        376 => 'Fixie',
        384 => 'Sepeda Lipat',
        379 => 'City Bike',
        381 => 'BMX',
        383 => 'Onthel',
      ),

如何从阵列“Sepeda MTB”，“Sepeda Lipat”等获得阵列

如您所知，JSON没有像往常一样的“值”或“名称”等参数名称。老实说，我的JSON响应不是那么短，而是之后的其他值。

当我使用此代码时

JSONObject cate = json.getJSONObject("categories");
                JSONObject a = cate.getJSONObject(secid);
                Log.e("a", a.toString());

这个logcat显示了这个

我已经解决了，这是我的解决方案

JSONObject cate = json.getJSONObject("categories");
                JSONObject a = cate.getJSONObject(secid);

                //get list of keys
                Iterator<String> keys=a.keys();
                while(keys.hasNext()){
                    String key=keys.next();
                    String value=a.getString(key);
                    Log.e("key", key);
                    Log.e("value", value);
                }

Answer 1

尝试

//result from server
JSONObject obj=json object
//get list of keys
Iterator<String> keys=obj.keys();
while(keys.hasNext())
{
String key=keys.next();
String value=obj.getString(key);
}

Answer 2

你应该使用类似Gson的东西为你完成所有的工作，你只需要创建具有相同名称变量的类，如果它是一个数组，只需要生成List＆lt;您的对象名称＆gt;。

Answer 3

这是我的实现：

for(int i=0;i<JsonObject.length();i++)
    {
        try {
            Log.d(TAG2,"Data Value Name "+JsonObject.names().get(i));
        } catch (JSONException e)
        {
            e.printStackTrace();``
        }
    }
