有没有办法对一个家庭的Widget动画？ [英] Is there a way to animate on a Home Widget?

问题描述

我想在主页窗口小部件，即一个AppWidgetProvider上使用的动画。我希望用帧动画技术：

I want to use an animation on a Home page Widget, i.e. an AppWidgetProvider. I was hoping to use the "Frame Animation" technique:

<一个href="http://developer.android.com/guide/topics/graphics/2d-graphics.html#frame-animation">http://developer.android.com/guide/topics/graphics/2d-graphics.html#frame-animation

我在一个活动成功地使用过。但我不能把这种code到AppWidgetProvider。

which I've used successfully in an activity. But I can't translate that code to an AppWidgetProvider.

基本上，在AppWidgetProvider，创建工作与RemoteViews对象，其中AFAIK不为我提供一个方法来获得引用到的ImageView的布局我打电话启动（）的动画。还有没有处理程序或回调，当插件播放这样我就可以做的start（）调用的。

Basically, in an AppWidgetProvider, I create and work with a RemoteViews object, which AFAIK doesn't provide me with a method to get a reference to an ImageView in the layout for me to call start() on the animation. There is also not a handler or a callback for when the widget displays so I can make the start() call.

有另一种方法可以做到这一点？我想，我也许可以做我自己的动画非常快的OnUpdate（）调用上的小部件，但似乎非常昂贵的。

Is there another way this can be done? I suppose that I can probably do the animation on my own with very fast onUpdate() calls on the widget, but that seems awfully expensive.

推荐答案

我目前正在创建一个窗口小部件需要精灵动画，我已经把如何的动画家里部件。是的，它是昂贵的事，所以我只在需要的部件。顺便说一句，原生Android的动画没有在远程视图支持。

I am currently creating an widget that "need" sprite animation, and I have put a blog post on how to animate home widget. Yes, it is expensive to do, so I do it only when the widget is needed. BTW, original android animation is not supported in remote views.
