public ViewPropertyAnimatorCompat setDuration (long value)

Sets the duration for the underlying animator that animates the requested properties. By default, the animator uses the default value for ValueAnimator. Calling this method will cause the declared value to be used instead.

Parameters
value The TimeInterpolator to be used for ensuing property animations.
Returns

Parameters
listener The listener to be called with AnimatorListener events. A value of null removes any existing listener.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat setStartDelay (long value)

Sets the startDelay for the underlying animator that animates the requested properties. By default, the animator uses the default value for ValueAnimator. Calling this method will cause the declared value to be used instead.

Prior to API 14, this method will do nothing.

Parameters
value The delay of ensuing property animations, in milliseconds. The value cannot be negative.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat setUpdateListener (ViewPropertyAnimatorUpdateListener listener)

Sets a listener for update events in the underlying Animator that runs the property animations.

Prior to API 19, this method will do nothing.

Parameters
listener The listener to be called with update events. A value of null removes any existing listener.
Returns
  • This object, allowing calls to methods in this class to be chained.

public void start ()

Starts the currently pending property animations immediately. Calling start() is optional because all animations start automatically at the next opportunity. However, if the animations are needed to start immediately and synchronously (not at the time when the next event is processed by the hierarchy, which is when the animations would begin otherwise), then this method can be used.

Prior to API 14, this method will do nothing.

public ViewPropertyAnimatorCompat translationX (float value)

This method will cause the View's translationX property to be animated to the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The value to be animated to.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat translationXBy (float value)

This method will cause the View's translationX property to be animated by the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The amount to be animated by, as an offset from the current value.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat translationY (float value)

This method will cause the View's translationY property to be animated to the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The value to be animated to.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat translationYBy (float value)

This method will cause the View's translationY property to be animated by the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The amount to be animated by, as an offset from the current value.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat withEndAction (Runnable runnable)

Specifies an action to take place when the next animation ends. The action is only run if the animation ends normally; if the ViewPropertyAnimator is canceled during that animation, the runnable will not run. This method, along with withStartAction(Runnable), is intended to help facilitate choreographing ViewPropertyAnimator animations with other animations or actions in the application.

For example, the following code animates a view to x=200 and then back to 0:

     Runnable endAction = new Runnable() {
         public void run() {
             view.animate().x(0);
         }
     };
     view.animate().x(200).withEndAction(endAction);

Prior to API 14, this method will run the action immediately.

For API 14 and 15, this method will run by setting a listener on the ViewPropertyAnimatorCompat object and running the action in that listener's onAnimationEnd(View) method.

Parameters
runnable The action to run when the next animation ends.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat withLayer ()

The View associated with this ViewPropertyAnimator will have its layer type set to LAYER_TYPE_HARDWARE for the duration of the next animation. As stated in the documentation for LAYER_TYPE_HARDWARE, the actual type of layer used internally depends on the runtime situation of the view. If the activity and this view are hardware-accelerated, then the layer will be accelerated as well. If the activity or the view is not accelerated, then the layer will effectively be the same as LAYER_TYPE_SOFTWARE.

This state is not persistent, either on the View or on this ViewPropertyAnimator: the layer type of the View will be restored when the animation ends to what it was when this method was called, and this setting on ViewPropertyAnimator is only valid for the next animation. Note that calling this method and then independently setting the layer type of the View (by a direct call to setLayerType(View, int, android.graphics.Paint)) will result in some inconsistency, including having the layer type restored to its pre-withLayer() value when the animation ends.

Prior to API 14, this method will do nothing.

For API 14 and 15, this method will run by setting a listener on the ViewPropertyAnimatorCompat object, setting a hardware layer in the listener's onAnimationStart(View) method, and then restoring the orignal layer type in the listener's onAnimationEnd(View) method.

Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat withStartAction (Runnable runnable)

Specifies an action to take place when the next animation runs. If there is a startDelay set on this ViewPropertyAnimator, then the action will run after that startDelay expires, when the actual animation begins. This method, along with withEndAction(Runnable), is intended to help facilitate choreographing ViewPropertyAnimator animations with other animations or actions in the application.

Prior to API 14, this method will run the action immediately.

For API 14 and 15, this method will run by setting a listener on the ViewPropertyAnimatorCompat object and running the action in that listener's onAnimationStart(View) method.

Parameters
runnable The action to run when the next animation starts.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat x (float value)

This method will cause the View's x property to be animated to the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The value to be animated to.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat xBy (float value)

This method will cause the View's x property to be animated by the specified value. Animations already running on the property will be canceled.

Prior to API 14, this method will do nothing.

Parameters
value The amount to be animated by, as an offset from the current value.
Returns
  • This object, allowing calls to methods in this class to be chained.

public ViewPropertyAnimatorCompat y (float value)

value The value to be animated to.
Returns
  • This object, allowing calls to methods in this class to be chained.
