Android 中 ArrayList 的分页

Question

I have ArrayList in my Constant file like below

public static ArrayList<ItemCategory> arrayListCategories = new ArrayList<>();

I am looking for display result with pagination so as mentioned here

I have tried below code

ArrayList<ItemCategory> arraylistsub = (ArrayList<ItemCategory>) Constant.arrayListCategories.subList(0,10);
        adapterCat = new AdapterCat(arraylistsub);
        recyclerView.setAdapter(adapterCat);

But its getting error called

java.lang.ClassCastException: java.util.ArrayList$SubList cannot be cast to java.util.ArrayList

I am not getting idea, whats wrong with it and how I can resolve it. Let me know if someone here can help me for same.

Thanks!

尝试这个

ArrayList<ItemCategory> arraylistsub = new ArrayList<>(Constant.arrayListCategories.subList(0,10));
