SwipeGesture Class |
滑动手势。你可以通过onBegin+onMove+onEnd关心整个滑动过程，也可以只使用onAction关注最后的滑动结果。滑动结果包括方向和加速度，可以从position和velocity获得。
注意onAction仅当滑动超过一定距离(actionDistance)时才触发。

Fields| Name | Description | |
|---|---|---|
  | ACTION_DISTANCE | |
| actionDistance |
The min distance to fire onAction event
派发onAction事件的最小距离。如果手指扫过的距离少于此值，onAction不会触发（但onEnd仍然会派发）
|
| delta |
移动的变化值
|
| position |
你可以在onBegin事件中设置这个值，那个后续将根据手指移动的距离修改这个值。如果不设置，那position初始为(0,0)，反映手指扫过的距离。
|
| snapping |
是否把变化量强制为整数。默认true。
|
| velocity |
手指离开时的加速度
