JSONArray转化List

获取json数据后，往往要获取需要的数据自己存放，一下面例子为例，
(一)，假如返回的一个Json是这样的：

{"Success":true,"Data":[{"IID":10,"UID":"d4b8bb3577c24898982912d10a61f611","SchoolUid":"b715f6eeef0c4a6d82c0016557f61390","InformationType":3,"InformationTitle":"文本n","InformationContent":"测试文本！测试文本<br>测试文本文本！！！！","CreatedDate":"2016-12-22T00:20:22.297","UpdateDate":"2016-12-22T00:20:22.297","CreateUser":null,"UpdateUser":null,"IsRemove":0,"IsActive":1,"DeviceUID":"b763ec53f4b0411090885805b1edf9c1","DisplayOrder":2,"IntervalNum":1},{"IID":9,"InformationType":2,"InformationTitle":"视频","InformationContent":"http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.mp4",{"IID":3,"UID":"f819d9cc086a4b1baac68c62bffad203","InformationType":1,"InformationTitle":"图片","InformationContent":"http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.jpg,http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.jpg,http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.jpg","CreatedDate":"2016-12-22T00:18:55.557","UpdateDate":"2016-12-22T00:18:55.557","CreateUser":"79419a8ad46043e1a8820d28bbb5bf3e","UpdateUser":"79419a8ad46043e1a8820d28bbb5bf3e","DisplayOrder":1,"IntervalNum":2}]},

（二），用网上的在线解析工具，我用的这个：http://tool.oschina.net/codeformat/json

格式化后看到是这样的数据

{
    "Success": true,"Data": [
        {
            "IID": 10,"UID": "d4b8bb3577c24898982912d10a61f611","SchoolUid": "b715f6eeef0c4a6d82c0016557f61390","InformationType": 3,"InformationTitle": "文本n","InformationContent": "测试文本！测试文本<br>测试文本文本！！！！","CreatedDate": "2016-12-22T00:20:22.297","UpdateDate": "2016-12-22T00:20:22.297","CreateUser": null,"UpdateUser": null,"IsRemove": 0,"IsActive": 1,"DeviceUID": "b763ec53f4b0411090885805b1edf9c1","DisplayOrder": 2,"IntervalNum": 1
        },{
            "IID": 9,"InformationType": 2,"InformationTitle": "视频","InformationContent": "http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.mp4",{
            "IID": 3,"UID": "f819d9cc086a4b1baac68c62bffad203","InformationType": 1,"InformationTitle": "图片","InformationContent": "http://images.qipeilong.cn/oldupload/8ec03d31-e0b4-4c89-a002-9adf6af85496.jpg,"CreatedDate": "2016-12-22T00:18:55.557","UpdateDate": "2016-12-22T00:18:55.557","CreateUser": "79419a8ad46043e1a8820d28bbb5bf3e","UpdateUser": "79419a8ad46043e1a8820d28bbb5bf3e","DisplayOrder": 1,"IntervalNum": 2
        }
    ]
}

（三）

1，定义一个类，里面定义想要的数据，比如我想获取IID 和UID

public class Data {

	private int IID;
	private String UID;


	public int getIID() {
		return IID;
	}
	public void setIID(int iID) {
		IID = iID;
	}
	public String getUID() {
		return UID;
	}
	public void setUID(String uID) {
		UID = uID;
	}

2，在访问请求后，返回的json里面处理：

此处List<Data> dataList;是全局变量

import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;

OkHttpUtils.post()
		.url("http://139.224.197.151:8082/Cms/GetTopic")
		.params(para)
		.build()
		.execute(new StringCallback() {

			@Override
			public void onResponse(String arg0,int arg1) {
				// TODO Auto-generated method stub

				JSONObject json;
				try {
					json = new JSONObject(arg0);
					JSONArray FileInformationArray = json.getJSONArray("Data");
					Log.i("FileInformationArray",""+FileInformationArray.toString());
					Gson mGson = new Gson();
					Type lisType = new TypeToken<LinkedList<Data>>(){}.getType();
					LinkedList<Data> datas = mGson.fromJson(FileInformationArray.toString(),lisType);

					for (int i = 0; i < datas.size(); i++) {
						Log.i("datas",""+datas.get(i).getIID());
						Log.i("datas",""+datas.get(i).getUID());
					}
				} catch (JSONException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}

			}

我的Log：

到此结束了！！！
