Change the FrameLayout height to match_parent.

Just use android:layout_alignParentTop.

I looked into your code. Wrap your layout in relative. Layout below and above only works in relative not in linear, and remove the two linear layout below that is wrapping the adView.
This should work

RecyclerView Adapter in CardView display issue

I have made a RecyclerView Adapter inflated in a CardView as shown in the images below. The cards have hidden layouts which become visible after being clicked on.
I am having a problem that when I have many sets of data as cards, and expand one or more cards, some of the cards become abnormal and invisible indefinitely. The cards not in current screen appear to face this problem.
\
When I scroll through the cards the view becomes more complicated and some cards become smaller and leave white spaces between them while content being of same size.
Please anyone help me solve the problem..

The align_XXX properties are only applicable in a RelativeLayout. LinearLayouts only lay things out linearly.
