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

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

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)
