i had same issue and solved like this for my horizontal RecyclerView:

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="wrap_content"
        android:layout_height="68dp"
        android:layout_centerHorizontal="true"
        android:orientation="horizontal"
        app:layoutManager="android.support.v7.widget.LinearLayoutManager" />

Here the main part is android:layout_centerHorizontal="true" and layout_width="wrap_content"
