Question
Android Studio help with ViewPager and ListView. I created ViewPager and the ListView but I don't know how to put it together with Listview (After clicking quiz4 button in the WorkFragment) like the one in the Demo video. Link for Demo below. Thanks
https://www.youtube.com/watch?v=B7csDJQqte8
My code for the WorkFragment.java
My code for fragment_work.xml
My code for ViewPagerActivity.java
My code for UtilLog.java below
My code for BlueFragment.java below (GreenFragment.java and RedFragment.java similar as BlueFragment.java so I won't paste below)
My code for the listview AdvanceListViewActivity.java below
My code for the BaseActivity.java below
And my XML code for activity_advance.xml below

<!-- Id of a list view uniquely identify it-->
<ListView

<!--Divider code in ListView-->
<ListView
