android解析嵌套的json对象 [英] android-parsing nested json Objects

问题描述

我必须在我的应用程序中实现json数据.但是我不知道如何从服务器获取数据.我正在使用ION库.

i have to implement json data in my application. but i can't get it how to fetch data from server. i am using ION library.

{
"search": [{
    "id": "5454003",
    "description": "Larger Than Life",
    "url": "http://audiojungle.net/item/larger-than-life/5454003",
    "type": "item",
    "sales": "1469",
    "rating": "5",
    "item_info": {
        "id": "5454003",
        "item": "Larger Than Life",
        "url": "http://audiojungle.net/item/larger-than-life/5454003",
        "user": "pinkzebra",
        "thumbnail": "https://0.s3.envato.com/files/67162834/upbeatsongwinner2.jpg",
        "sales": "1469",
        "rating": "5",
        "rating_decimal": "4.96",
        "cost": "18.00",
        "preview_type": "audio",
        "preview_url": "https://0.s3.envato.com/files/94250640/preview.mp3",
        "length": "2:35"
    }
} ] }

这是我的json数据.我想在我的应用程序中显示成本"，用户"等数据.但我不明白.离子代码在这里，

this is my json data. i want to display in my application data like "cost" , "user" ect. but i didn't get it. ion code is here,

Ion.with(this)
            .load("http://marketplace.envato.com/api/edge/search:audiojungle,,happy.json")
            .asJsonObject().setCallback(new FutureCallback<JsonObject>() {

                @Override
                public void onCompleted(Exception arg0, JsonObject data) {
                    // TODO Auto-generated method stub

                }
            });

所以，如果有人知道，请帮助我.预先谢谢你.

so if anybody knows then please help me. thank you in advance.

推荐答案

您发布的第一个信息是一些具有误导性的信息，我检查了您发布的答案并且工作正常代码给你，

The first info that you posted was has some misleading information, i checked the answer that you posted and i have a working code for you,

代码:

Ion.with(this)
        .load("http://marketplace.envato.com/api/edge/search:audiojungle,,happy.json")
        .asString().setCallback(new FutureCallback<String>() {
    @Override
    public void onCompleted(Exception e, String result) {
        try {
            parseJson(new JSONObject(result));
        } catch (JSONException e1) {
            e1.printStackTrace();
        }
    }
});

要解析响应数据:

private void parseJson(JSONObject result) {

    try {
        JSONArray jsonArray = result.getJSONArray("search");
        for(int a=0;a<jsonArray.length();a++){

            System.out.println(jsonArray.getJSONObject(a).getString("id"));
            System.out.println(jsonArray.getJSONObject(a).getString("description"));
            System.out.println(jsonArray.getJSONObject(a).getString("url"));
            System.out.println(jsonArray.getJSONObject(a).getString("type"));
            System.out.println(jsonArray.getJSONObject(a).getString("sales"));
            System.out.println(jsonArray.getJSONObject(a).getString("rating"));

            // JSON data with in JSONObject "item_info"
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("id"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("item"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("url"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("user"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("thumbnail"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("sales"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("rating"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("rating_decimal"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("cost"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("preview_type"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("preview_url"));
            System.out.println(jsonArray.getJSONObject(a).getJSONObject("item_info").getString("length"));

        }
    } catch (JSONException e) {
        e.printStackTrace();
    }

}

• 请记住，使用JSONArray(org.json.JSONArray)和JSONObject(org.json.JSONObject)构成org.json库，而不是JsonArray(com.google.gson.JsonArray;)或JsonObject(com.google.gson). com.google.gson库中的JsonObject)，它会使事情变得混乱；
• 为了使事情变得容易，请在此处粘贴响应 http://json.parser.online.fr/看看哪个是jsonobject或数组
• Remember to use JSONArray(org.json.JSONArray) and JSONObject(org.json.JSONObject) form the org.json libary not JsonArray(com.google.gson.JsonArray;) or JsonObject(com.google.gson.JsonObject) from the com.google.gson library, it get things mess up;
• To make things easy paste response here http://json.parser.online.fr/ to see which one is a jsonobject or array
