ClickableSpan

Kotlin |Java

abstract class ClickableSpan : CharacterStyle, UpdateAppearance

kotlin.Any
↳	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 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:

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

Text with ClickableSpan.

Inherited functions

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.
