MaskFilterSpan

Kotlin |Java

open class MaskFilterSpan : CharacterStyle, UpdateAppearance

kotlin.Any
↳	android.text.style.CharacterStyle
	↳	android.text.style.MaskFilterSpan

Span that allows setting a MaskFilter to the text it's attached to.

For example, to blur a text, a android.graphics.BlurMaskFilter can be used:

MaskFilter blurMask = new BlurMaskFilter(5f, BlurMaskFilter.Blur.NORMAL);
  SpannableString string = new SpannableString("Text with blur mask");
  string.setSpan(new MaskFilterSpan(blurMask), 10, 15, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Text blurred with the MaskFilterSpan.

From class CharacterStyle

CharacterStyle!

getUnderlying()

Returns "this" for most CharacterStyles, but for CharacterStyles that were generated by wrap, returns the underlying CharacterStyle.

CharacterStyle!

wrap(cs: CharacterStyle!)

A given CharacterStyle can only applied to a single region of a given Spanned. If you need to attach the same CharacterStyle to multiple regions, you can use this method to wrap it with a new object that will have the same effect but be a distinct object so that it can also be attached without conflict.
