推荐答案

首先确保您打包PIL /抱枕[只需将其添加到在构建APK的要求之一]为GIF加载，否则纯Python加载器Android游戏很慢的会被使用，其次请详细说明您的方盒子是什么意思？

First make sure that you package pil/pillow [just add it to one of the requirements while building the apk] for gif loading, otherwise a pure python loader that is very slow for android would be used, Second please elaborate what you mean by the square box?

更新：更新后的例子表明，你正在使用AsyncImage与本地源，异步图像是彪与您可以只使用一个图片类。

Update: your updated example shows that you are using AsyncImage with a local source, Async Image is ment to be used with a remote url for local sources you can just use a Image class.

第二：如果你得到一个白色的背景，而不是像你给它在错误的道路。确保你的图片是在目录或目录是在发射正确的地方present present。

Second: If you are getting a white background instead of a image you gave it the wrong path. Make sure your image is present in the directory or that your directory is present in the right place on the launcher.

更新3：如前所述的问题是使用PIL GIF图像加载器。并非所有的图像使用它。它可以在你的桌面原因PIL未安装和纯Python GIF加载器来代替。该装载机将不会对速度问题的android事业使用。

Update 3: The issue as stated earlier is with gif image loader using pil. Not all images work with it. It works on your desktop cause pil isn't installed and a pure python gif loader is used instead. This loader would not be usable on android cause of speed issues.

一个解决方法是使用GIMP打开和保存图像。它应该正常工作即可。
另一种方式是促进和修复：使用PIL为GIF装载机...（我必须提醒有网络上这么多不同的GIF每个都有自己的略有变化，确保一件作品，会导致人越来越破。）

One workaround is to use gimp to open and save the image. It should work properly then. One other way is to contribute and fix: the loader using pil for gif...(I must warn there are so many different gifs on web each with their own slightly changes. Making sure one works would lead to others getting broken.)

要重现您的问题在桌面上只安装枕头。

To reproduce your issue on desktop just install pillow.

有能够拿出在使用的GIF动画许多文物，我建议你在使用图片（PNG / JPG ...）一个 .zip文件和设置到源。你摆脱文物的方式。

There are many artifacts that can come up while using gifs for animation, I'd recommend you use images(png/jpg...) in a .zip and set that to the source. That way you get rid of the artifacts.

请确保GIF或由Image类提供的.zip文件的动画，只用于在您不需要控制动画很多的情况。像静态动画不改变

Please make sure that gif or .zip animation provided by the Image class, is only used for situations where you don't need to control the animation a lot. Like for static animations that don't change.

如果您的动画需要超越这个，那么你应该通过手动加载精灵表在阿特拉斯管理您的动画。

If your animations needs go beyond this then you should manage your animation manually by loading a sprite sheet in a Atlas.
