Parsing Json Data Format

The text will not be transferred here. Click the link to see it later...
But there is a problem. The several formats he introduced are not what I want. The json format obtained from the server is as follows:
[{"Description": "\ u5e7f \ u544a3", "img": "http: \/clostyle2012.eicp.net \/images \/appimg \/ad \/3.jpg ", "link": "34" },{ "description": "\ u5e7f \ u544a2", "img": "http: \// clostyle2012.eicp.net \/images \/appimg \/ad \/2.jpg", "link": "33" },{ "description": "\ u5e7f \ u544a1 ", "img": "http: \/clostyle2012.eicp.net \/images \/appimg \/ad \/1.jpg"," link ":" 32 "}]
At first glance, we can see that the outside is a JSONArray, And the element is three JSONObject objects. However, if the array does not have a key, you cannot press the one mentioned in the previous article. I have been searching for it for a long time. I have tried it many times and finally got it done. But I don't know if it is the best.
The example format in his article is the same as what I want. I used a part of its code...
