Public Constructors

public AbstractDraweeController(DeferredReleaser deferredReleaser, Executor uiThreadImmediateExecutor, String id, Object callerContext)

Public Methods

public void addControllerListener(ControllerListener<? super INFO> controllerListener)

Adds controller listener.

public void addControllerListener2(ControllerListener2<INFO> controllerListener2)

public Animatable getAnimatable()

For an animated image, returns an Animatable that lets clients control the animation.

Returns

• animatable, or null if the image is not animated or not loaded yet

public Object getCallerContext()

Gets the analytic tag & caller context

public String getContentDescription()

Gets accessibility content description.

Returns

• content description, or null if the image has no content description

public DraweeHierarchy getHierarchy()

Gets the hierarchy

public String getId()

Gets the controller id.

public abstract Map<String, Object> obtainExtrasFromImage(INFO info)

public void onAttach()

Called when the view containing the hierarchy is attached to a window (either temporarily or permanently).

public boolean onClick()

public void onDetach()

Called when the view containing the hierarchy is detached from a window (either temporarily or permanently).

public boolean onTouchEvent(MotionEvent event)

Called when the view containing the hierarchy receives a touch event.

Returns

• true if the event was handled by the controller, false otherwise

public void onViewportVisibilityHint(boolean isVisibleInViewportHint)

An optional hint whether the view containing the hierarchy is currently within the visible viewport or not.

public void release()

public void removeControllerListener(ControllerListener<? super INFO> controllerListener)

Removes controller listener.

public void removeControllerListener2(ControllerListener2<INFO> controllerListener2)

public void setContentDescription(String contentDescription)

Sets accessibility content description.

public void setControllerViewportVisibilityListener(ControllerViewportVisibilityListener controllerViewportVisibilityListener)

Sets the controller viewport visibility listener

public void setHierarchy(DraweeHierarchy hierarchy)

Sets the hierarchy.

The controller should be detached when this method is called.

Parameters

| hierarchy | This must be an instance of SettableDraweeHierarchy |
