android - 动画期间的高 CPU 负载

Question

在动画期间 cpu 负载非常高(高达 75%)

是否有优化代码以降低 CPU 负载的方法？

我的代码:

ImageView myImageView = (ImageView)findViewById(R.id.ImageView02);

    animSet = new AnimationSet(true);

    animSet.setInterpolator(new LinearInterpolator());
    animSet.setFillAfter(true);
    animSet.setFillEnabled(true);

    final RotateAnimation animRotate = new RotateAnimation(0.0f, 360.0f,
            RotateAnimation.RELATIVE_TO_SELF, 0.5f,
            RotateAnimation.RELATIVE_TO_SELF, 0.5f);
    animRotate.setRepeatCount(Animation.INFINITE);
    animRotate.setDuration(rotor_duration());
    animRotate.setFillAfter(true);
    animSet.addAnimation(animRotate);

    myImageView.startAnimation(animSet);

Answer 1

有没有办法设置旋转之间的延迟？通过设置延迟并设置更大的角度值(以保持旋转速度恒定)应该会有所帮助。
