problem
There's this suspicious line:
java.lang.ClassCastException: android.view.ViewGroup$LayoutParams
Have you tried to explicitly write:
LinearLayout.LayoutParams
instead of just
LayoutParams
whereever it appears?
(because each Layout has their own set of LayoutParams that are not
necessarily compatible with each other).
