public void centerTabItem(int position) {
    tabHost.setCurrentTab(position);
    final TabWidget tabWidget = tabHost.getTabWidget();
    final int screenWidth = getWindowManager().getDefaultDisplay().getWidth();
    final int leftX = tabWidget.getChildAt(position).getLeft();
    int newX = 0;

    newX = leftX + (tabWidget.getChildAt(position).getWidth() / 2) - (screenWidth / 2);
    if (newX < 0) {
        newX = 0;
    }
    horizontalScrollView.scrollTo(newX, 0);
}
