| 29 | * Represents a group of Animations that should be played together. |
| 30 | * The transformation of each individual animation are composed |
| 31 | * together into a single transform. |
| 32 | * If AnimationSet sets any properties that its children also set |
| 33 | * (for example, duration or fillBefore), the values of AnimationSet |
| 34 | * override the child values. |
Chet Haase | c861bd7 | 2011-09-06 07:12:44 -0700 | [diff] [blame] | 35 | * |
| 36 | * <p>The way that AnimationSet inherits behavior from Animation is important to |
| 37 | * understand. Some of the Animation attributes applied to AnimationSet affect the |
| 38 | * AnimationSet itself, some are pushed down to the children, and some are ignored, |
| 39 | * as follows: |
| 40 | * <ul> |
| 41 | * <li>duration, repeatMode, fillBefore, fillAfter: These properties, when set |
| 42 | * on an AnimationSet object, will be pushed down to all child animations.</li> |
| 43 | * <li>repeatCount, fillEnabled: These properties are ignored for AnimationSet.</li> |
| 44 | * <li>startOffset, shareInterpolator: These properties apply to the AnimationSet itself.</li> |
| 45 | * </ul> |
| 46 | * Starting with {@link android.os.Build.VERSION_CODES#ICE_CREAM_SANDWICH}, |
| 47 | * the behavior of these properties is the same in XML resources and at runtime (prior to that |
| 48 | * release, the values set in XML were ignored for AnimationSet). That is, calling |
| 49 | * <code>setDuration(500)</code> on an AnimationSet has the same effect as declaring |
| 50 | * <code>android:duration="500"</code> in an XML resource for an AnimationSet object.</p> |
