Android listview extra space at the end when scrolling

Question

I experienced weird behavior with smooth scrolling in the list. I have 30 items in the list. When I smooth the scroll through

listview.smoothScrollToPositionFromTop(29, 0);

additional space appears at the end of the screen. Actually the list is browsed a little. The image is attached below. But if I scroll manually, there will be no space. What can be done to allow this behavior?

Here is my layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/holo_orange_light">

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

</RelativeLayout>

I firmly believe that I will go to RecyclerView. If you do not want to move. Here is the work. Just add this method to your activity and name it.

private void smoothScrollToTop(final int pos) {
    listView.smoothScrollToPositionFromTop(pos, 0);
    listView.post(new Runnable() {
        @Override
        public void run() {
            listView.smoothScrollToPosition(pos);
        }
    });
}

This is well tested. and worked for me. And here it is deduced.

try this for your xml:

<ListView
android:id="@+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="0dp"
android:clipToPadding="false"/>
