Try this answer,

public static void setListViewHeightBasedOnChildren(final ListView listView) {
    listView.post(new Runnable() {
        @Override
        public void run() {
            ListAdapter listAdapter = listView.getAdapter();
            if (listAdapter == null) {
                return;
            }
            int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
            int listWidth = listView.getMeasuredWidth();
            for (int i = 0; i < listAdapter.getCount(); i++) {
                View listItem = listAdapter.getView(i, null, listView);
                listItem.measure(
                        View.MeasureSpec.makeMeasureSpec(listWidth, View.MeasureSpec.EXACTLY),
                        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));


                totalHeight += listItem.getMeasuredHeight();
                Log.d("listItemHeight" + listItem.getMeasuredHeight(), "___________");
            }
            ViewGroup.LayoutParams params = listView.getLayoutParams();
            params.height = (int) ((totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1))));
            listView.setLayoutParams(params);
            listView.requestLayout();

        }
    });
   }
