Trying to use this on anything gives me a java.lang.RuntimeException: PARAGRAPH span must start at paragraph boundary
I got the exception java.lang.RuntimeException: PARAGRAPH span must start at paragraph boundary as well.
I got the exception java.lang.RuntimeException: PARAGRAPH span must start at paragraph boundary.
I think its coming from this line
output.setSpan(new BulletSpan(15 * mListParents.size()), start, output.length(), 0);
and
output.setSpan(new LeadingMarginSpan.Standard(15 * mListParents.size()), start, output.length(), 0);
If you comment it and run it, it is working
can we make the bullet a bit larger ?
Hello, Is there any way I can handle <font> tag in HtmlTagHandler as it is already being handled by Html.fromHtml() ? I want to handle 'size' in <font> tag but I do not want to use <h1> or <big> tags.
Me too @tasneembohra, I need to manipulate font tags h1, h2, a, br.
I'm trying to manipulate a custom tag. I have <J> tag and I want to change the color of the text within the tag
