Public Constructors

public TranslateAnimation (Context context, AttributeSet attrs)

Since: API Level 1

Constructor used when a TranslateAnimation is loaded from a resource.

Parameters

context	Application context to use
attrs	Attribute set from which to read values

public TranslateAnimation (float fromXDelta, float toXDelta, float fromYDelta, float toYDelta)

Since: API Level 1

Constructor to use when building a TranslateAnimation from code

Parameters

fromXDelta	Change in X coordinate to apply at the start of the animation
toXDelta	Change in X coordinate to apply at the end of the animation
fromYDelta	Change in Y coordinate to apply at the start of the animation
toYDelta	Change in Y coordinate to apply at the end of the animation

public TranslateAnimation (int fromXType, float fromXValue, int toXType, float toXValue, int fromYType, float fromYValue, int toYType, float toYValue)

Since: API Level 1

Constructor to use when building a TranslateAnimation from code

Parameters

fromXType	Specifies how fromXValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT.
fromXValue	Change in X coordinate to apply at the start of the animation. This value can either be an absolute number if fromXType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise.
toXType	Specifies how toXValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT.
toXValue	Change in X coordinate to apply at the end of the animation. This value can either be an absolute number if toXType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise.
fromYType	Specifies how fromYValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT.
fromYValue	Change in Y coordinate to apply at the start of the animation. This value can either be an absolute number if fromYType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise.
toYType	Specifies how toYValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT.
toYValue	Change in Y coordinate to apply at the end of the animation. This value can either be an absolute number if toYType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise.

Public Methods

public void initialize (int width, int height, int parentWidth, int parentHeight)

Since: API Level 1

Initialize this animation with the dimensions of the object being animated as well as the objects parents. (This is to support animation sizes being specifed relative to these dimensions.)

Objects that interpret Animations should call this method when the sizes of the object being animated and its parent are known, and before calling getTransformation(long, Transformation).

Parameters

width	Width of the object being animated
height	Height of the object being animated
parentWidth	Width of the animated object's parent
parentHeight	Height of the animated object's parent

Protected Methods

protected void applyTransformation (float interpolatedTime, Transformation t)

Since: API Level 1

Helper for getTransformation. Subclasses should implement this to apply their transforms given an interpolation value. Implementations of this method should always replace the specified Transformation or document they are doing otherwise.

Parameters

interpolatedTime	The value of the normalized time (0.0 to 1.0) after it has been run through the interpolation function.
t	The Transformation object to fill in with the current transforms.
