How to force height of listView to be size so that every row is visible?

问题

I have nested listView. How to force height of listView to be size so that every row is visible ? ListView is nested inside ScrollView so scroll doesn't work for ListView so I need to make that all items are visible inside ListView which is nested ion ScrollView ( there is above and bellow more things).

To calculate hieght of listView

public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        // pre-condition
        return;
    }

    int totalHeight = 0;
    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(),
            MeasureSpec.AT_MOST);
    for (int i = 0; i < listAdapter.getCount(); i++) {
        View listItem = listAdapter.getView(i, null, listView);
        listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += listItem.getMeasuredHeight();
    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight
            + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}

Pass listview object to this methode.

 setListViewHeightBasedOnChildren(listView)
