Package icyllis.modernui.text.style

Class ClickableSpan

java.lang.Object

icyllis.modernui.text.style.CharacterStyle

icyllis.modernui.text.style.ClickableSpan

All Implemented Interfaces:

UpdateAppearance, Cloneable

Direct Known Subclasses:

URLSpan

public abstract class ClickableSpan
extends CharacterStyle
implements UpdateAppearance

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(icyllis.modernui.view.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.
