BulletSpan

open class BulletSpan : LeadingMarginSpan, ParcelableSpan

A span which styles paragraphs as bullet points (respecting layout direction).

BulletSpans must be attached from the first character to the last character of a single paragraph, otherwise the bullet point will not be displayed but the first paragraph encountered will have a leading margin.

BulletSpans allow configuring the following elements:

• gap width - the distance, in pixels, between the bullet point and the paragraph. Default value is 2px.
• color - the bullet point color. By default, the bullet point color is 0 - no color, so it uses the TextView's text color.
• bullet radius - the radius, in pixels, of the bullet point. Default value is 4px.

<code>SpannableString string = new SpannableString("Text with\nBullet point");
 string.setSpan(new BulletSpan(), 10, 22, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);</code>

To construct a BulletSpan with a gap width of 40px, green bullet point and bullet radius of 20px:

<code>SpannableString string = new SpannableString("Text with\nBullet point");
 string.setSpan(new BulletSpan(40, color, 20), 10, 22, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);</code>
