android控件旋转一圈动画封装

简单的封装，从fromDegrees 转toDegrees 延续时间durationMillis

mIv_logo.startAnimation(getRotateAnimation(0, 360, 500));

public static Animation getRotateAnimation(float fromDegrees,
float toDegrees, int durationMillis) {
RotateAnimation rotate = new RotateAnimation(fromDegrees, toDegrees,
Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
0.5f);
rotate.setDuration(durationMillis);
rotate.setFillAfter(true);
return rotate;
}
