Method Detail

currentAnimationTimeMillis

public static long currentAnimationTimeMillis()

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

Loads an Animation object from a resource

Parameters:

context - Application context used to access resources

id - The resource id of the animation to load

Returns:

The animation object reference by the specified id

Throws:

Resources.NotFoundException - when the animation cannot be loaded

loadLayoutAnimation

public static LayoutAnimationController loadLayoutAnimation(Context context,
                                                            int id)

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

Parameters:

c - Context for loading resources

fromLeft - is the object to be animated coming from the left

Returns:

The new animation

makeOutAnimation

public static Animation makeOutAnimation(Context c,
                                         boolean toRight)

c - Context for loading resources

toRight - is the object to be animated exiting to the right

Returns:

The new animation

makeInChildBottomAnimation

public static Animation makeInChildBottomAnimation(Context c)

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

Parameters:

c - Context for loading resources

Returns:

The new animation

loadInterpolator
