DrawableMarginSpan

open class DrawableMarginSpan : LeadingMarginSpan, LineHeightSpan
kotlin.Any
   ↳ android.text.style.DrawableMarginSpan

A span which adds a drawable and a padding to the paragraph it's attached to.

If the height of the drawable is bigger than the height of the line it's attached to then the line height is increased to fit the drawable. DrawableMarginSpan allows setting a padding between the drawable and the text. The default value is 0. The span must be set from the beginning of the text, otherwise either the span won't be rendered or it will be rendered incorrectly.

For example, a drawable and a padding of 20px can be added like this: 

<code>SpannableString string = new SpannableString("Text with a drawable.");
  string.setSpan(new DrawableMarginSpan(drawable, 20), 0, string.length(),
  Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);</code>
 Text with a drawable and a padding.
