Using JsonArray vs ArrayList as a data set to RecyclerView Adapter

Question

I have used both ArrayList<> and JsonArray as the data sets in the adapter. One of the major difference I found was that the data set changes for the local data in Adapter was not reflected back in the calling class for JsonArray.

I wanted to know using which one is better and is my observation correct.

Also if my data set involves extracting data from a webservice(that gives me Json form data) will my changing it to ArrayList<> be better.

Answer 1

JsonArray implemented by ArrayList under the hood. http://grepcode.com/file/repo1.maven.org/maven2/org.json/json/20080701/org/json/JSONArray.java

So its very similar variants for app performance. Use what you like =)

Answer 2

As far as I know JsonArray isn't much slower than ArrayList. So I believe that you should be ok using JsonArray. We would need to see some code to help out with the problem when using jsons.
