Android supports the Gesture API since version 1.6. 从1.6版开始，Android就支持Gesture API。 The API can be located in the package android.gesture , and lets you store, load, draw and recognize gestures. 该API可位于包android.gesture ，并允许您存储，加载，绘制和识别手势。 The below tutorial will show you a proof-of-concept application how you can make use of Gesture API. 以下教程将向您展示概念验证应用程序，如何使用Gesture API。
