MaskFilterSpan

Kotlin |Java

public class MaskFilterSpan
extends CharacterStyle implements UpdateAppearance

java.lang.Object
↳	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 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);
