Fix Android ListViewItem not highlighted when selecting programmatically

I have a ListView like this:

<ListView
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:choiceMode="singleChoice"
    android:listSelector="?attr/colorPrimarySurface" />

However, when I tried to highlight on the first item by default using the performItemClick method, it won't work.

listView.post {
    listView.performItemClick(
        listView.getChildAt(0),
        0,
        listView.adapter.getItemId(0)
    )
}

After searching on the internet, i found the solution, two lines needed to be added before calling the performItemClick method.

listView.requestFocusFromTouch();
listView.setSelection(0);

Now it works as expected.
