You cannot set alignment in HTML text but you can use a SpannableStringBuilder instead. It's verbose but it gets the job done.

E.g.

private Spanned getFormattedLabelText(String text, String subText) {
    String fullText = String.format("%s\n%s", text, subText);

    int fullTextLength = fullText.length();
    int titleEnd = text.length();

    SpannableStringBuilder s = new SpannableStringBuilder(fullText);

    // Center align the text
    AlignmentSpan alignmentSpan = new AlignmentSpan.Standard(Layout.Alignment.ALIGN_CENTER);
    s.setSpan(alignmentSpan, 0, fullTextLength, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

    // Make the title bold
    s.setSpan(new StyleSpan(Typeface.BOLD), 0, titleEnd, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); //bold

    // Make the subtext small
    int smallTextSize = DisplayUtil.getPixels(TypedValue.COMPLEX_UNIT_SP, 10);
    s.setSpan(new AbsoluteSizeSpan(smallTextSize), titleEnd + 1, fullTextLength, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); //bold

    return s;
}

Then set the TextView text as usual:

myTextView.setText(getFormattedLabelText("Title", "Subtitle"));
