Android TextView making the font different size per line

I want to use a TextView

The first line, I want the font to be 24dp the second line, I want the font to be 16dp

Could this be done with 1 TextView or will I need to create 2 of them?

Solution

  • It can be done in 1 TextView with SpannableString

    From https://developer.android.com/reference/android/text/style/RelativeSizeSpan

    You can use:

    SpannableString string = new SpannableString("Text with relative size span");
string.setSpan(new RelativeSizeSpan(1.5f), 10, 24, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

    Where 1.5f would be an increase of 50%, 10 the starting index and 24 the end index

    public void setSpan (Object what, 
                int start, 
                int end, 
                int flags)
