Dynamically Adding And Removing Tabs Using Arraypageradapter

This is a continuation from the question I 1st asked here, Creating a new ArrayPagerAdapter with variety of Fragments. You were dead on about me using the wrong ArrayAdapter I just

Solution 1:

One of the next blocks i'm getting stuck on right now is creating the PageDescriptor objects in the ArrayList passed into SimplePageAdapter

PageDescriptor is an interface. Create your own class (e.g., BlainePageDescriptor) that implements the interface. This is covered in the documentation.

I've tried copying and pasting the SimplePageDescriptor class used in the Demo into my code

That will not solve your problem.

Your problem, as I understand it, is that you want your ArrayPagerAdapter to be able to handle N different types of pages (JudgeMainFragment, JudgeClassifyFragment, etc.). That requires you to return the proper fragment from createFragment(), given the supplied PageDescriptor. Hence, you need to create your own PageDescriptor implementation (e.g., BlainePageDescriptor). That class needs to hold onto sufficient information to both satisfy the PageDescriptor interface and be able to tell createFragment() what sort of fragment to create.
