swiperefresh 嵌套头布局为viewpager的listview时候的问题

Question

在我用swiperefresh嵌套头布局为viewpager的listview时候，刷新的逻辑是清空listview填充布局的集合，viewpager的集合，然后重新请求数据请求完以后布局就乱套了，我重写了listview的onscrolllistener中的

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
                     int visibleItemCount, int totalItemCount) {
    boolean enable = false;
    if(listView != null && listView.getChildCount() > 0){
        // check if the first item of the list is visible
        boolean firstItemVisible = listView.getFirstVisiblePosition() == 0;
        // check if the top of the first item is visible
        boolean topOfFirstItemVisible = listView.getChildAt(0).getTop() == 0;
        // enabling or disabling the refresh layout
        enable = firstItemVisible && topOfFirstItemVisible;
    }
    swipe.setEnabled(enable);
};


    重写了这个为了解决listview和swiperefreshlayout的冲突。我也重写了swiperefresh'layout的
    @Override
public boolean canChildScrollUp() {
    if (view != null && view instanceof AbsListView) {
        final AbsListView absListView = (AbsListView) view;
        return absListView.getChildCount() > 0
                && (absListView.getFirstVisiblePosition() > 0 || absListView.getChildAt(0)
                .getTop() < absListView.getPaddingTop());
    }
    return super.canChildScrollUp();
}

    可是刷新完换是有问题
    布局上面的viewpager乱套了

viewpager不在顶部啊

下拉刷新你直接加载第一页的数据，然后刷新Adapter不需要将集合中的数据都清除掉
