如何为 UI 创建手势控制的旋转图像
我正在尝试找出使图像旋转的最佳方法 用户用手指向左或向右拖动它。我想尝试 将用户手指移动的速率与图像移动的速率相匹配 旋转。
我已经完成了应用程序的基本设置，包括菜单和 我想要什么，这一切都在模拟器上运行得很好， 我只是不确定如何处理这部分。
我可以编写应用程序所需的所有逻辑，但我只是做得不好 设计UI时，我脑子里有一张图片，我实际上做了一个 几个模拟图像，我只是不知道如何让它继续下去 在 Android 中，任何帮助将不胜感激。
I'm trying to figure out the best way to make an image rotate along
with a user's finger dragging it left or right. I want to try and
match the rate a user's finger is moving with the rate the image is
rotating.
I've got the basic setup for my application going, with the menus and
whatnot I want to have, and that's all running great on the emulator,
I'm just not sure how to approach this part.
I can code all the logic I need for my app, I'm just not doing to well
designing the UI, I have a picture in mind, I've actually made a
couple mock images of it, I just can't figure out how to get it going
in Android, and any help would be appreciated.

我建议您首先查看：

我不太确定如何解决现实生活中的旋转问题，但似乎 OpenGL 可能会帮助你。

或者也许可以通过自定义动画解决方案？

告诉我们，你是如何解决的！

I am not really sure how to solve the problem with the real-life rotation but it seems OpenGL might help you.
http://developer.android.com/guide/topics/graphics/opengl.html
or maybe a solution through custom animations is possible?
