plz help me out what's the error and how to handle two fragment with two recyclerview in one activity.
THANK YOU for your concern!
回答1:
android.support.v7.widget.RecyclerView
use this code in your xml file to create a listview. Simple!
回答2:
You probably want to use android.support.v7.widget.RecyclerView.
Additional info that you don't need to know
RecycleListView is a nested class of android.support.v7.app.AlertController. One would refer to it as android.support.v7.app.AlertController$RecycleListView (the dollar sign). This is why it crashed at this point.
RecycleListView extends ListView not RecyclerView. That's why it would later crash with ClassCastException when you would try to use it in Java.
RecycleListView is an internal class of appcompat-v7 not to be used in your project.
回答3:
I made the same mistake. Try to replace
android.support.v7.app.AlertController.RecycleListView
with
android.support.v7.widget.RecyclerView
