Scroller startScroll() fling() 参数详解

fling()

/**
     * Start scrolling based on a fling gesture. The distance travelled will
     * depend on the initial velocity of the fling.
     * 
     * @param startX Starting point of the scroll (X)
     * @param startY Starting point of the scroll (Y)
     * @param velocityX Initial velocity of the fling (X) measured in pixels per
     *        second.
     * @param velocityY Initial velocity of the fling (Y) measured in pixels per
     *        second
     * @param minX Minimum X value. The scroller will not scroll past this
     *        point.
     * @param maxX Maximum X value. The scroller will not scroll past this
     *        point.
     * @param minY Minimum Y value. The scroller will not scroll past this
     *        point.
     * @param maxY Maximum Y value. The scroller will not scroll past this
     *        point.

public void fling(int startX, int startY, int velocityX, int velocityY,
int minX, int maxX, int minY, int maxY

翻译过来：开始滚动基于一个抛掷手势，距离的移动取决于你抛掷的初始速度。

startX：开始滑动的X scroll的距离 X为正 表示在左边
startY：开始滑动的Y scroll的距离 Y为正 表示在上边
velocityX：X 正数 朝左 负数 朝右
velocityY：Y 正数 朝上 负数 朝下
minX：最小的X值 如果velocityX为负 则朝右方向移动minX
maxX 最大的X值 如果velocityX为正 朝左移动maxX
minY 最小的Y值 如果velocityY为负 则朝上方向移动minY
maxY
