我加入一个发光的动画效果，以一个标志。到目前为止，我已经设法获得辉光图像背后的标志，使用LayeredDrawable，但我无法弄清楚如何制作动画。我发现，AlphaAnimation会达到预期的效果，但遗憾的是我只能把它应用在看法，并不可绘制。我怎样才能达到这种效果呢？

I am adding a glow animation effect to a logo. So far, I have managed to get the glow image behind the logo, using a LayeredDrawable, but I can't figure out how to animate it. I have found that AlphaAnimation would achieve the desired effect, but unfortunately I can only apply it on Views, not Drawables. How can I achieve this effect?

推荐答案

的Andr​​oid 3.0推出的属性动画。

Android 3.0 introduced Property Animations.

不幸的是，这仅限于安卓3.0及以上，这将不会在手机上得到任何时间很快。

Unfortunately, this is limited to Android 3.0 and up which won't get on phones any time soon.
