From source file:cgeo.geocaching.CacheDetailActivity.java

private static void fixTextColor(final Spannable spannable, final int backgroundColor) {
    final ForegroundColorSpan[] spans = spannable.getSpans(0, spannable.length(), ForegroundColorSpan.class);

    for (final ForegroundColorSpan span : spans) {
        if (ColorUtils.getContrastRatio(span.getForegroundColor(), backgroundColor) < CONTRAST_THRESHOLD) {
            final int start = spannable.getSpanStart(span);
            final int end = spannable.getSpanEnd(span);

            //  Assuming that backgroundColor can be either white or black,
            // this will set opposite background color (white for black and black for white)
            spannable.setSpan(new BackgroundColorSpan(backgroundColor ^ 0x00ffffff), start, end,
                    Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
