使用下面的code找到touchGESTURE。

use the below code to find the touchGESTURE.

protected boolean touchEvent(TouchEvent message) 
{
   switch(message.getEvent()) 
   {
      case TouchEvent.GESTURE:
         TouchGesture gesture = message.getGesture();
         switch(gesture.getEvent()) 
         {
           case TouchGesture.NAVIGATION_SWIPE:
             Dialog.alert("Swipe direction: " + gesture.getSwipeDirection()  
             +            ", "
             +            "\nMagnitude: " + gesture.getSwipeMagnitude());
             return true;
         }
   }
   return false;
}
