Paragraph Spacings Using SpannableStringBuilder In TextView

As the question indicates, I am working on a TextView which will show formatted text using SpannableStringBuilder. It has multiple paragraphs and I would like to know what would be

Solution 1:

Implement the LineHeightSpan and override chooseHeight method as follows

@Override
public void chooseHeight(CharSequence text, int start, int end,
        int spanstartv, int v, FontMetricsInt fm) {
    Spanned spanned = (Spanned) text;
    int st = spanned.getSpanStart(this);
    int en = spanned.getSpanEnd(this);
    if (start == st) {
        fm.ascent -= TOP_SPACING;
        fm.top -= TOP_SPACING;
    }
    if (end == en) {
        fm.descent += BOTTOM_SPACING;
        fm.bottom += BOTTOM_SPACING;
    }
}

Don't forget to add \n at the end of your each paragraph text.
