Java 从JSONArray（PHP到ANDROID）获取多维数组

嗨，我的php文件的json_编码输出是：

[{"index":1,"questions":"If the number of berths in a train are 900 more than one-fifth of it, find the total berths in the train?","options":["1145","1130","1135","1125","1120"],"answers":"1125","useranswers":"1145"}]

在我的android代码中，我必须将选项存储在2D数组中

 JSONArray jArray = new JSONArray(result); 
            JSONObject json_data=null; 
            JSONArray options_array=null;
            JSONArray option_ids_array=null;
            no_of_questions=jArray.length();
            questions=new String[no_of_questions];
            question_id=new String[no_of_questions];
            options=new String[no_of_questions][];
            option_ids=new String[no_of_questions][];
            for(int i=0;i<no_of_questions;i++){
                json_data = jArray.getJSONObject(i); 
                questions[i] =json_data.getString("questions");
                question_id[i] =json_data.getString("question_ids");
                Log.i("Question ids",""+question_id[i]);
                options_array=json_data.getJSONArray("options");
                option_ids_array=json_data.getJSONArray("option_ids");
                options[i]=new String[options_array.length()];
                option_ids[i]=new String[options_array.length()];
                for(int j=0;j<options_array.length();j++){
                    options[i][j]=options_array.get(j).toString();
                    option_ids[i][j]=option_ids_array.get(j).toString();
                }
             } 

怎么做？

请帮帮我，我是ANDROID新手。

你试过什么？你在哪里找的？不熟悉Android并不是不做研究的借口这与Android无关，请查看org.json库。你需要操纵JSONArray。很抱歉，我的问题甚至不清楚，但马赫帮助了我。使用这个它可能会帮助你谢谢马赫。你帮了我很多

        String s = "[{\"index\":1,\"questions\":\"If the number of berths in a train are 900 more than one-fifth of it, find the total berths in the train?\",\"options\":[\"1145\",\"1130\",\"1135\",\"1125\",\"1120\"],\"answers\":\"1125\",\"useranswers\":\"1145\"}]";
        try {
            JSONArray a;
            a = new JSONArray(s);
            JSONObject o = (JSONObject) a.get(0);
            JSONArray options = o.getJSONArray("options");
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
