| 28 | * This class enables automatic and optimized animation of select properties on View objects. |
| 29 | * If only one or two properties on a View object are being animated, then using an |
| 30 | * {@link android.animation.ObjectAnimator} is fine; the property setters called by ObjectAnimator |
| 31 | * are well equipped to do the right thing to set the property and invalidate the view |
| 32 | * appropriately. But if several properties are animated simultaneously, or if you just want a |
| 33 | * more convenient syntax to animate a specific property, then ViewPropertyAnimator might be |
| 34 | * more well-suited to the task. |

Chet Haase | d666cf3 | 2011-03-01 07:31:30 -0800 | [diff] [blame] | 36 | * <p>This class may provide better performance for several simultaneous animations, because |
| 37 | * it will optimize invalidate calls to take place only once for several properties instead of each |
| 38 | * animated property independently causing its own invalidation. Also, the syntax of using this |
Chet Haase | a00f386 | 2011-02-22 06:34:40 -0800 | [diff] [blame] | 39 | * class could be easier to use because the caller need only tell the View object which |
