如果不需要监听，则和使用一个RelativeLayout一样简单。


如果是对自定义的View做OverScroll的话需要设置OvserScrollCheckListener.
 overScrollLayout.setOverScrollCheckListener(OverScrollCheckListener l)
 在OverScrollCheckListener中
 public int getContentViewScrollDirection() ；用于指定overscroll的方向，
 包括横向和纵向：OverScrollLayout.SCROLL_VERTICAL，OverScrollLayout.SCROLL_HORIZONTAL。
  public boolean canOverScroll(float dealtX, float dealtY, View contentView)；用于判断是否可以OverScroll.
  public boolean canScrollUp();用于判断是否到达顶部，用于检查垂直Overscroll;
  public boolean canScrollDown();用于判断是否到达底部，用于检查垂直OverScroll；
  public boolean canScrollLeft()；用于判断是否到达左边界,用于检查水平OverScroll；
  public boolean canScrollRight() ；用于判断是否已到达右边界,用于检查水平OverScroll。
  
  以为StaggeredGridView为例子，要实现它的OverScroll  那么OverScrollCheckListener 可以这么实现：
         overScrollLayout.setOverScrollCheckListener(new OverScrollCheckListener() {
            @Override
            public int getContentViewScrollDirection() {
                return OverScrollLayout.SCROLL_VERTICAL;
            }
            @Override
            public boolean canOverScroll(float dealtX, float dealtY, View contentView) {
                if (dealtY < 0 && !canScrollUp()) {
                    return true;
                }
                if (dealtY > 0 && !canScrollDown()) {
                    return true;
                }
                return false;
            }
            @Override
            public boolean canScrollUp() {
                int fp = staggeredGridView.getFirstPosition();
                if (fp == 0) {
                    View child = staggeredGridView.getChildAt(0);
                    if (child.getTop() >= staggeredGridView.getPaddingTop()) {
                        return false;
                    }
                }
                return true;
            }
            @Override
            public boolean canScrollDown() {
                int fp = staggeredGridView.getFirstPosition();
                int lp = staggeredGridView.getChildCount() + fp - 1;
                if (lp == staggeredGridView.getAdapter().getCount() - 1) {
                    int numClos = staggeredGridView.getColumnCount();
                    int childCount = staggeredGridView.getChildCount();
                    for (int i = 1; i <= numClos; i++) {
                        View view = staggeredGridView.getChildAt(childCount - i);
                        if (view.getBottom() <= staggeredGridView.getHeight() + staggeredGridView.getPaddingBottom()) {
                            return false;
                        }
                    }
                }
                return true;
            }
            @Override
            public boolean canScrollLeft() {
                return false;
            }
            @Override
            public boolean canScrollRight() {
                return false;
            }
        });
