使用RxJava从翻新响应中获取N数据

Question

My API is sending a response similar to the snippet below. The dataList contains 100 items. I want to load it 10 items at a time, instead of waiting for all the items to fetch. Can anyone help me out with this, How can i achieve this with RxJava. ( I am using Retrofit for Networking )

someresponse{ "status":true, "dataList":[ .....] }

You have misunderstanding how JSON schema work. To be able to parse JSON you SHOULD wait for the entire response body.

While that said, you still can override read method as described in the answer. You will need to parse JSON manually, putting in the stack curly braces until you meet dataList: { and the end of the item in it } , but there's no guaranty the JSON won't be malformed. At the end of the day, it's definitely not worth it.

Also, note that JSON data shouldn't be that heavy as files or smth. If you have 1Mb + of JSON it means you're doing something wrong and you need to redesign your backend API. Otherwise, you shouldn't be wasting time on this issue.
