set Typeface to all TextViews in a ViewGroup for Android

gistfile1.java

    // recursively apply typeface to our textviews
    static final void setTypeface(ViewGroup viewGroup, Typeface typeface)
    {
        if (viewGroup == null) return;

        int children = viewGroup.getChildCount();
        Log.d(TAG, "setTypeface " + viewGroup + " : " + children);
        for (int i=0; i<children; i++)
        {
            View view = viewGroup.getChildAt(i);
            if (view instanceof ViewGroup) setTypeface((ViewGroup)view, typeface);
            if (view instanceof TextView)
            {
                TextView textView = (TextView) view;
                textView.setTypeface(typeface);
            }
        }
    }

thanks.
