| ↳ | android.view.ViewPropertyAnimator |
This class enables automatic and optimized animation of select properties on View objects. If only one or two properties on a View object are being animated, then using an ObjectAnimator is fine; the property setters called by ObjectAnimator are well equipped to do the right thing to set the property and invalidate the view appropriately. But if several properties are animated simultaneously, or if you just want a more convenient syntax to animate a specific property, then ViewPropertyAnimator might be more well-suited to the task.
This class may provide better performance for several simultaneous animations, because it will optimize invalidate calls to take place only once for several properties instead of each animated property independently causing its own invalidation. Also, the syntax of using this class could be easier to use because the caller need only tell the View object which property to animate, and the value to animate either to or by, and this class handles the details of configuring the underlying Animator class and starting it.
This class is not constructed by the caller, but rather by the View whose properties it will animate. Calls to animate() will return a reference to the appropriate ViewPropertyAnimator object for that View.

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.

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.

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);
| runnable | The action to run when the next animation ends. |
|---|
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(int, android.graphics.Paint)) will result in some inconsistency, including having the layer type restored to its pre-withLayer() value when the animation ends.
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.
