Research direction
Start by reproducing the ViewPager/ListView behavior with a data source of size 3, then inspect the shown scrollTo override and the isTopHidden condition. Verify the header, adjacent item counts, and bottom ListView respond correctly to an upward fling after the header hides.

Description
bug : listview in viewpager 有问题当数据源的size=3,切换的时候数据源左边和右边的个数会改变
question:当头部可见时，用力向上滑，当头部隐藏后，底部的ListView中的类容不会通过惯性自动向上滑动，但我见过的其他应用是可以惯性滑动的，例如QQ音乐，魅族应用中心详情
看了代码是吧height的大小限制，要实现例如新浪微博的评论效果，要怎么做呢
@Override
public void scrollTo(int x, int y) {
if (y < 0) {
y = 0;
}
Log.e("scrollTo", "y======" + y);
if (y > mTopViewHeight) {
y = mTopViewHeight;
}
if (y != getScrollY()) {
super.scrollTo(x, y);
}
isTopHidden = getScrollY() == mTopViewHeight;
}
