1) 定义手势
导入并运行GestureBuilder
导出mnt/sdcard/gestures
2) 识别手势
a) gestures文件拷贝到res\raw\
b) layout 新增GestureOverlayView，用来做布局
c) 加载手势库
final GestureLibrary library = GestureLibraries.fromRawResource(this, R.raw.gestures);
library.load();
d) 识别手势
GestureOverlayView OverlayView = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);
OnGesturePerformedListener listener = new OnGesturePerformedListener()
{
@Override
public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture)
