Answer 1

Try this, it works for my same problem

public static boolean setListViewHeightBasedOnItems(ListView listView) {

ListAdapter listAdapter = listView.getAdapter();
if (listAdapter != null) {

    int numberOfItems = listAdapter.getCount();

    // Get total height of all items.
    int totalItemsHeight = 0;
    for (int itemPos = 0; itemPos < numberOfItems; itemPos++) {
        View item = listAdapter.getView(itemPos, null, listView);
        item.measure(0, 0);
        totalItemsHeight += item.getMeasuredHeight();
    }

    // Get total height of all item dividers.
    int totalDividersHeight = listView.getDividerHeight() * 
            (numberOfItems - 1);

    // Set list height.
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalItemsHeight + totalDividersHeight;
    listView.setLayoutParams(params);
    listView.requestLayout();

    return true;

} else {
    return false;
}}

requestLayout() method is called on the view because something has changed that invalidated its layout - forces redrawing.
