旋转180度

 

Animation anim =new RotateAnimation(0f, 180f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
anim.setFillAfter(true); // 设置保持动画最后的状态
anim.setDuration(500); // 设置动画时间
anim.setInterpolator(new AccelerateInterpolator()); // 设置插入器
anim.setAnimationListener(new Animation.AnimationListener() {@Overridepublic void onAnimationStart(Animation animation) {Log.i("lgq", "re==logtest===onAnimationStart==");}@Overridepublic void onAnimationEnd(Animation animation) {Log.i("lgq", "re==logtest===onAnimationEnd==" );}@Overridepublic void onAnimationRepeat(Animation animation) {Log.i("lgq", "re==logtest===onAnimationRepeat==");}
});
localstatusfreeview.startAnimation(anim);

 

反转180度

 

Animation anim =new RotateAnimation(180f, 0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
anim.setFillAfter(true); // 设置保持动画最后的状态
anim.setDuration(500); // 设置动画时间
anim.setInterpolator(new AccelerateInterpolator()); // 设置插入器
localstatusfreeview.startAnimation(anim);

 

2、 圆形图片循环旋转动画

private ObjectAnimator mObjectAnimator;
private long mCurrentPlayTime;
private boolean ifop=true;
public static  int rotationTime = 20000;

/*** 设置旋转的动画*/
public void setAnimation() {if (mObjectAnimator == null) {mObjectAnimator = ObjectAnimator.ofFloat(tvHobby, "rotation", 0, 360);mObjectAnimator.setDuration(rotationTime);mObjectAnimator.setInterpolator(new LinearInterpolator());mObjectAnimator.setRepeatCount(ValueAnimator.INFINITE);}startAnimation();
}

 

/*** 暂停旋转*/
private void stopAnimation() {mCurrentPlayTime = mObjectAnimator.getCurrentPlayTime();mObjectAnimator.cancel();
}/*** 开始旋转*/
private void startAnimation() {mObjectAnimator.start();mObjectAnimator.setCurrentPlayTime(mCurrentPlayTime);
}

附：开启暂停

if (ifop) {stopAnimation();ifop = !ifop;
} else {startAnimation();ifop = !ifop;
}
