Consider this layout:

Top level: horizontal linearlayout (match_parent width/height, weightSum = 1)
Child CoordinatorLayout (weight 1, width 0 - as is standard practice)
As well as an appbarlayout, the coordinator layout has a framelayout child (this is necessary) which in turn has a recyclerview child. The recyclerview items are simple textviews using layout_width="match_parent".

However, for some reason, the text views are being laid out as if they have layout_width="wrap_content"

There are two ways to workaround this:

1. Change the coordinator layout_width = "0dp"

or

2. remove the app:layout_behavior="@string/appbar_scrolling_view_behavior" from the FrameLayout child of coordinator_layout
