很多时候，利用触摸屏的Fling、Scroll等Gesture（手势）操作来操作会使得应用程序的用户体验大大提升，比如用Scroll手势在 浏览器中滚屏，用Fling在阅读器中翻页等。在Android系统中，手势的识别是通过 .OnGestureListener接口来实现的，不过William翻遍了Android的官方文档也没有找到一个相 关的例子，API Demo中的TouchPaint也仅仅是提到了onTouch事件的处理，没有涉及到手势。Android Developer讨论组里也有不少人有和我类似的问题，结合他们提到的方法和我所做的实验，我将给大家简单讲述一下Android中手势识别的实现。-In many cases, the use of the touch screen Fling, Scroll, etc. Gesture (gesture) operation allows the user to operate will greatly enhance the experience of the application, such as scrolling in the browser with Scroll gesture, flip with Fling in Reader and so on. In the Android system, gesture recognition is through. OnGestureListener interface to achieve, but William rummaged official Android documentation but could not find a relevant example, the API Demo TouchPaint is only mentioned onTouch event handling, no involves gestures. Android Developer discussion groups where there are a lot of people and I have a similar problem, combined with their methods and experiments mentioned I did, I will give you a brief talk about Android in gesture recognition is achieved.
