public AnimationUtils()

方法详细信息

currentAnimationTimeMillis

public static long currentAnimationTimeMillis()

Returns the current animation time in milliseconds. This time should be used when invoking Animation.setStartTime(long). Refer to SystemClock for more information about the different available clocks. The clock used by this method is not the "wall" clock (it
is not System.currentTimeMillis()).

返回：the current animation time in milliseconds另请参见：SystemClock

loadAnimation

public static Animation loadAnimation(Context context,
int id)
throws Resources.NotFoundException

Loads an Animation object from a resource

参数：

context

 - Application context used to access resources

id

 - The resource id of the animation to load返回：The animation object reference by the specified id抛出：

Resources.NotFoundException

 - when the animation cannot be loaded

loadLayoutAnimation

public static LayoutAnimationController loadLayoutAnimation(Context context,
int id)
throws Resources.NotFoundException

抛出：

Resources.NotFoundException

makeInAnimation

public static Animation makeInAnimation(Context c,
boolean fromLeft)

Make an animation for objects becoming visible. Uses a slide and fade effect.

参数：

c

 - Context for loading resources

fromLeft

 - is the object to be animated coming from the left返回：The new animation

makeOutAnimation

public static Animation makeOutAnimation(Context c,
boolean toRight)

Make an animation for objects becoming invisible. Uses a slide and fade effect.

参数：

c

 - Context for loading resources

toRight

 - is the object to be animated exiting to the right返回：The new animation

makeInChildBottomAnimation

public static Animation makeInChildBottomAnimation(Context c)

Make an animation for objects becoming visible. Uses a slide up and fade effect.

参数：

c

 - Context for loading resources返回：The new animation

loadInterpolator

public static Interpolator loadInterpolator(Context context,
int id)
throws Resources.NotFoundException

Loads an Interpolator object from a resource

参数：

context

 - Application context used to access resources

id

 - The resource id of the animation to load返回：The animation object reference by the specified id抛出：

Resources.NotFoundException
