      extended by android.view.animation.RotateAnimation

public class RotateAnimation
extends Animation

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 Detail

RotateAnimation

public RotateAnimation(Context context,
                       AttributeSet attrs)
Constructor used whan an RotateAnimation is loaded from a resource.

Parameters:
context - Application context to use
attrs - Attribute set from which to read values

RotateAnimation

public RotateAnimation(float fromDegrees,
                       float toDegrees)
Constructor to use when building a RotateAnimation from code. Default pivotX/pivotY point is (0,0).

Parameters:
fromDegrees - Rotation offset to apply at the start of the animation.
toDegrees - Rotation offset to apply at the end of the animation.

RotateAnimation

public RotateAnimation(float fromDegrees,
                       float toDegrees,
                       float pivotX,
                       float pivotY)
Constructor to use when building a RotateAnimation from code

Parameters:
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.

RotateAnimation

public RotateAnimation(float fromDegrees,
                       float toDegrees,
                       int pivotXType,
                       float pivotXValue,
                       int pivotYType,
                       float pivotYValue)
Constructor to use when building a RotateAnimation from code

Parameters:
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.
Method Detail

applyTransformation

protected void applyTransformation(float interpolatedTime,
                                   Transformation t)
Description copied from class: Animation
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.

Overrides:
applyTransformation in class Animation
Parameters:
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.

initialize

public void initialize(int width,
                       int height,
                       int parentWidth,
                       int parentHeight)
Description copied from class: Animation
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 Animation.getTransformation(long, android.view.animation.Transformation).

Overrides:
initialize in class Animation
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
