Android的AnimationDrawable并知道何时动画结束 [英] Android AnimationDrawable and knowing when animation ends

问题描述

我想要做一个动画的几个图像文件，这样做的AnimationDrawable工作得非常好。不过，我需要的时候动画开始就知道它结束时（即添加像Animation.AnimationListener侦听器）。有寻找答案之后，我有一种不好的预感在AnimationDrawable不支持的听众。

I want to do an animation with several image-files, and for this the AnimationDrawable works very well. However, I need to know when the animation starts and when it ends (i.e add a listener like the Animation.AnimationListener). After having searched for answers, I'm having a bad feeling the AnimationDrawable does not support listeners..

有谁知道怎么做帧一帧图像动画在Android？

Does anyone know how to do frame-by-frame image animation on Android?

推荐答案

您应该知道在启动时，因为你是一个开始吧。而且，由于你知道的持续时间（因为你指定它），你应该知道它何时结束。

You should know when it starts, as you're the one starting it. And, since you know the duration (since you specify it), you should know when it ends.

您也可以遍历所有的帧（ getNumberOfFrames（）），并总结了各（的持续时间getDuration（）），如果您不想硬线在Java code的持续时间。

You can also iterate over all of the frames (getNumberOfFrames()) and sum up the durations of each (getDuration()), if you do not want to hard-wire a duration in your Java code.
