n建立手勢資料庫

n在模擬器上執行Gestures Builder應用程式

n建立手勢並命名會產生手勢資料庫檔案（檔名為gestures），儲存在SD卡內

n使用DDMS將手勢資料庫檔案拷貝至指定應用程式的res/raw目錄即可用來比對使用者手勢

n新增GestureOverlayView元件，之後使用者會在其上畫出手勢

nGestureOverlayView元件呼叫addOnGesturePerformedListener()向OnGesturePerformedListener註冊並實作onGesturePerformed()

n當使用者畫出手勢時， onGesturePerformed()會自動被呼叫並執行
