android – Nested scrollview automatically scrolls to bottom

I have a GridView within a NestedScrollView. I have used the code below to resize the GridView whenever the content of the GridView is changed. This works fine, however the NestedScrollView scrolls to the very bottom when I swipe from fragment 3 of the app back to fragment 2 (where the NestedScrollView resides). This doesn’t happen when swiping from fragment 1 to fragment 2, oddly. It also doesn’t happen directly after resizing the GridView.

How can I repress the NestedScrollView from scrolling to the bottom?

private static void resizeGridView(GridView gridView, int items, int columns) {
    ViewGroup.LayoutParams params = gridView.getLayoutParams();
    params.height = singleGridHeight * items;
    gridView.setLayoutParams(params);
    gridView.requestLayout();
}

The following system methods are called when swiping between fragments:
