Constructor used when a ScaleAnimation is loaded from a resource.
context | Application context to use |
---|---|
attrs | Attribute set from which to read values |

fromX | Horizontal scaling factor to apply at the start of the animation |
---|---|
toX | Horizontal scaling factor to apply at the end of the animation |
fromY | Vertical scaling factor to apply at the start of the animation |
toY | Vertical scaling factor to apply at the end of the animation |

---|---|
toX | Horizontal scaling factor to apply at the end of the animation |
fromY | Vertical scaling factor to apply at the start of the animation |
toY | Vertical scaling factor to apply at the end of the animation |
pivotX | The X coordinate of the point about which the object is being scaled, specified as an absolute number where 0 is the left edge. (This point remains fixed while the object changes size.) |
pivotY | The Y coordinate of the point about which the object is being scaled, specified as an absolute number where 0 is the top edge. (This point remains fixed while the object changes size.) |

pivotXType | Specifies how pivotXValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT. |
pivotXValue | The X coordinate of the point about which the object is being scaled, specified as an absolute number where 0 is the left edge. (This point remains fixed while the object changes size.) This value can either be an absolute number if pivotXType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise. |
pivotYType | Specifies how pivotYValue should be interpreted. One of Animation.ABSOLUTE, Animation.RELATIVE_TO_SELF, or Animation.RELATIVE_TO_PARENT. |
pivotYValue | The Y coordinate of the point about which the object is being scaled, specified as an absolute number where 0 is the top edge. (This point remains fixed while the object changes size.) This value can either be an absolute number if pivotYType is ABSOLUTE, or a percentage (where 1.0 is 100%) otherwise. |
Initialize this animation with the dimensions of the object being animated as well as the objects parents. (This is to support animation sizes being specified 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)
.
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 |
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.
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. |
