Android Gusture 手势识别小案例

Step1: 生成一个Android Gusture Builder程序用于画Gusture然后存储起来用于其它的项目

首先导入 android SDK \android-sdk-windows\samples\android-8\ 目录下的GestureBuilder项目，用于生成Gusture类库

导入过程中要加入几个文件才能导入到Eclipse中，如下图所示：这几个文件可以从任意android项目中copy

.classpath .project default.properties 3个文件

导入之后生成项目如下图所示：将该项目安装到模拟器中，如下图所示：

然后会在sdcard

step2:应用此程序生成我们需要的手势，点击 Add gesture按钮添加手势，随便添加几个手势之后

然后会在sdcard中生成一个gusture文件如图所示

step2:将此gusture文件导出到桌面，然后再复制到新建的项目中去

step3:新建项目Gusture,并将刚才的gusture文件导入到/res/raw目录下，如下图所示

step4: 设计应用的UI界面，main.xml
