Parsing JSON data in Android/Java

Question

I am trying to get the URL from the following JSON response:

{
    "json": {
        "errors": [],
        "data": {
            "url": "urlIWant.com",
            "id": "asdklfjads",
            "name": "sdfjklsdf"
        }
    }
}

I have been banging my head against the wall trying to get the URL out of this response. What code do I need to access that url in Android?

Here is the latest few lines of code that I have tried to get the url.

 JSONObject json = new JSONObject(responseStr);
 json = json.getJSONObject("data"); //Get the "data" object out of the JSON
 url = json.getString("url"); //Grab the URL from the object
 Log.d("JSON URL", url); //url is null here

Answer 1

似乎您应该先尝试从“ json”字段中获取内容，然后再尝试访问“数据”。

Answer 2

You could use retrofit along with GSON to do the work for you. There are some tutorials out there teaching how to use them.

Answer 3

1个班轮：

new JSONObject(json).getJSONObject("json").getJSONObject("data").getString("url")
