Custom Controls-rotation animation, custom controls Rotation

Custom Controls-rotation animation, custom controls Rotation

RotateAnimation (float fromDegrees, float toDegrees, int limit txtype, float limit txvalue, int limit tytype, float limit tyvalue)
Parameter description:
Float fromDegrees: the starting angle of rotation.
Float toDegrees: the end angle of the rotation.
Int limit txtype: The scaling mode of the X axis. values include ABSOLUTE, RELATIVE_TO_SELF, and RELATIVE_TO_PARENT.
Float limit txvalue: The scaling value of X coordinates.
Int equaltytype: The scaling mode of the Y axis. values include ABSOLUTE, RELATIVE_TO_SELF, and RELATIVE_TO_PARENT.
Float tytyvalue: The scaling value of Y coordinates.

 

// Animation. setRepeatCount (int repeatCount); // you can specify the number of repetitions.
// Animation. setFillAfter (boolean); // whether the animation is in the running state after execution
// Animation. setStartOffset (long startOffset); // the waiting time before execution
