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.

Remarks

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);}

Constructors

ClickableSpan()
ClickableSpan(IntPtr, JniHandleOwnership)	A constructor used when creating managed representations of JNI objects; called by the runtime.

Properties

Class	Returns the runtime class of this `Object`. (Inherited from Object)
Handle	The handle to the underlying Android instance. (Inherited from Object)
JniIdentityHashCode	(Inherited from Object)
JniPeerMembers
PeerReference	(Inherited from Object)
ThresholdClass	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
ThresholdType	This API supports the Mono for Android infrastructure and is not intended to be used directly from your code.
Underlying	Returns "this" for most CharacterStyles, but for CharacterStyles that were generated by `#wrap`, returns the underlying CharacterStyle. (Inherited from CharacterStyle)

Methods

Clone()	Creates and returns a copy of this object. (Inherited from Object)
Dispose()	(Inherited from Object)
Dispose(Boolean)	(Inherited from Object)
Equals(Object)	Indicates whether some other object is "equal to" this one. (Inherited from Object)
GetHashCode()	Returns a hash code value for the object. (Inherited from Object)
JavaFinalize()	Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object)
Notify()	Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object)
NotifyAll()	Wakes up all threads that are waiting on this object's monitor. (Inherited from Object)
OnClick(View)	Performs the click action associated with this span.
SetHandle(IntPtr, JniHandleOwnership)	Sets the Handle property. (Inherited from Object)
ToArray<T>()	(Inherited from Object)
ToString()	Returns a string representation of the object. (Inherited from Object)
UnregisterFromRuntime()	(Inherited from Object)
UpdateDrawState(TextPaint)	Makes the text underlined and in the link color.
Wait()	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object)
Wait(Int64)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
Wait(Int64, Int32)	Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object)
