you can try this function to update the height of listView

public static void updateListViewHeight(ListView myListView) {
    ListAdapter myListAdapter = myListView.getAdapter();
    if (myListAdapter == null) {
        return;
    }
    // get listview height
    int totalHeight = 0;
    int adapterCount = myListAdapter.getCount();
    for (int size = 0; size < adapterCount; size++) {
        View listItem = myListAdapter.getView(size, null, myListView);
        listItem.measure(0, 0);
        totalHeight += listItem.getMeasuredHeight();
    }
    // Change Height of ListView
    ViewGroup.LayoutParams params = myListView.getLayoutParams();
    params.height = (totalHeight
            + (myListView.getDividerHeight() * (adapterCount));
    myListView.setLayoutParams(params);
}
