↳ | android.view.animation.RotateAnimation |
An animation that controls the rotation of an object. This rotation takes place int the X-Y plane. You can specify the point to use for the center of the rotation, where (0,0) is the top left point. If not specified, (0,0) is the default rotation point.

Constructor used when a RotateAnimation is loaded from a resource.
context | Application context to use |
---|---|
attrs | Attribute set from which to read values |
Constructor to use when building a RotateAnimation from code. Default pivotX/pivotY point is (0,0).
fromDegrees | Rotation offset to apply at the start of the animation. |
---|---|
toDegrees | Rotation offset to apply at the end of the animation. |
Constructor to use when building a RotateAnimation from code
fromDegrees | Rotation offset to apply at the start of the animation. |
---|---|
toDegrees | Rotation offset to apply at the end of the animation. |
pivotX | The X coordinate of the point about which the object is being rotated, specified as an absolute number where 0 is the left edge. |
pivotY | The Y coordinate of the point about which the object is being rotated, specified as an absolute number where 0 is the top edge. |

fromDegrees | Rotation offset to apply at the start of the animation. |
---|---|
toDegrees | Rotation offset to apply at the end of the animation. |
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 rotated, specified as an absolute number where 0 is the left edge. 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 rotated, specified as an absolute number where 0 is the top edge. 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 specifed relative to these dimensions.)
Objects that interpret a 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 Transofrmation object to fill in with the current transforms. |
