Android: last card of RecyclerView cut off. Can't scroll any further. Why would this happen?

Question

Here is a screenshot of what is happening:

For some reason, the last card of the RecyclerView is not showing up properly. This is a weird occurrence especially since the RecyclerView is just wrapping content.

<android.support.v7.widget.RecyclerView
    android:id="@+id/cardList"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="3dp"
    android:layout_marginLeft="8dp"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

Why might something like this occur? How can I make it so that the RecyclerView is not cut off?

Answer 1

choosing wrap_content as the attribute for layout_width and layout_height causes the cut-off on RecyclerViews

Answer 2

RecyclerView cannot have WRAP_CONTENT as layout_height. The solution is to set layout_height to a specific value like "100dp", like the following:

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="100dp"
    ...
/>

Now if the value in the xml is not what you want, you can set layout_height in the code using requestLayout();
