Android Support Library rev 23.2 and RecyclerView

Question

Updated to Android Support Library rev 23.2 and it added full screen spaces to RecyclerView between each item. Has anybody experienced this issue?

Answer 1

This occurs when your RecyclerView rows have their size set to match_parent in the scrolling direction.

For example, if a RecyclerView with a vertical LinearLayoutManager has the following layout for each row, that row will now actually match the parent's height now. Before version 23.2.0 it would still simply wrap the content.

<View
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

In this case, changing the height to wrap_content will resolve the issue.

This issue is mentioned briefly in the announcement blog post:

Due to this change, make sure to double check the layout parameters of your item views: previously ignored layout parameters (such as MATCH_PARENT in the scroll direction) will now be fully respected.
