IconMarginSpan

Kotlin |Java

public class IconMarginSpan
extends Object implements LeadingMarginSpan, LineHeightSpan

java.lang.Object
↳	android.text.style.IconMarginSpan

Paragraph affecting span, that draws a bitmap at the beginning of a text. The span also allows setting a padding between the bitmap and the text. The default value of the padding is 0px. The span should be attached from the first character of the text.

For example, an IconMarginSpan with a bitmap and a padding of 30px can be set like this:

 SpannableString string = new SpannableString("Text with icon and padding");
 string.setSpan(new IconMarginSpan(bitmap, 30), 0, string.length(),
 Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

for working with a {@link android.graphics.drawable.Drawable} instead of a {@link android.graphics.Bitmap Bitmap}.
