2. Enabling the fast scroll thumb. (fastScrollEnabled)

The scroll function is activated since several items have been added to the ListView, you can use it by moving up or down while pressing and holding your finger. By the way, if a very large amount of items are in the ListView, There is a discomfort to have to take action to move several times to move to the last item on the first item.

In this case, you can make quick positioning by enabling "fastScrollEnabled" attribute and moving the thumb.

  * android:fastScrollEnabled - Enabling the fast scroll thumb.
        > true or false.

If you do not use "fastScrollEnabled" or set it to "false", the thumb is not appeared.

    <ListView
        android:id="@+id/listview1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

If "fastScrollEnabled" is set to "true", you can see the thumb and make quick positioning by touch.

    <ListView
        android:id="@+id/listview1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fastScrollEnabled="true" />
