ClickableSpan

Kotlin |Java

public abstract class ClickableSpan
extends CharacterStyle implements UpdateAppearance

java.lang.Object
↳	android.text.style.CharacterStyle
	↳	android.text.style.ClickableSpan

Known direct subclasses

TextLinks.TextLinkSpan, URLSpan

TextLinks.TextLinkSpan	A ClickableSpan for a TextLink.
URLSpan	Implementation of the `ClickableSpan` that allows setting a url string.

If an object of this type is attached to the text of a TextView with a movement method of LinkMovementMethod, the affected spans of text can be selected. If selected and clicked, the onClick(View) method will be called.

The text with a ClickableSpan attached will be underlined and the link color will be used as a text color. The default link color is the theme's accent color or android:textColorLink if this attribute is defined in the theme. For example, considering that we have a CustomClickableSpan that extends ClickableSpan, it can be used like this:

SpannableString string = new SpannableString("Text with clickable text");
string.setSpan(new CustomClickableSpan(), 10, 19, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Text with ClickableSpan.
