ClickableSpan

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(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
.
