[补充]可以在主线程控制,特别注意

scrollView3.postDelayed(new Runnable() {                @Override                public void run() {                    scrollView3.scrollTo(0, num * scrollItemHeight);                }            }, 500);  if (mScrollX != x || mScrollY != y) 这个判断语句有没有通过是关键所在. 这也间接说明了, 在Activity 没初始化完成, ScrollView 对象获取的一些信息是不准确的, 直接导致了scrollTo() 方法无效.

ScrollView 用的是scroller做的滑动, 但是 scroller 被scrollView隐藏了 你无法调用   你可以直接自己写个Scrollview 代码完全copy 自带的scrollView 然后把scroller暴露出来!

可以派生的。如果(mScroller.computeScrollOffset()返回false则表示滚动结束了。
