How to specify list item count in preview of recyclerview in Android Studio? : <p>The recyclerview layout is defined as </p>

<pre><code>     &lt;android.support.v7.widget.RecyclerView
            android:layout_marginTop="15dp"
            android:id="@+id/call_detail_list"
            android:scrollbars="vertical"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            tools:listitem="@layout/call_item"
            /&gt;
</code></pre>

<p>In the preview, I can see the list items from the specified layout,
but the number of item is 10. Is there any way that can be changed?</p>
