Question

我使用https://github.com/bulletnoid/StaggeredGridView这个库来制作一个pinterest样式布局，并在此布局上使用pulltorefresh。此外，还有一个幻灯片菜单，可以选择不同的类别，并根据用户选择的类别，刷新并再次填充。

Pulltorefresh工作正常。

如果用户位于布局顶部并在幻灯片菜单上选择一个类别，则它可以正常工作。但是，如果用户在布局底部并在幻灯片菜单上选择一个类别，则其工作不正确。

场景，布局顶部并在slidemenu上选择类别并重新填充交错布局。它正常工作

我想我和你一样使用相同的pinterest样式库也有同样的问题。我把这个问题解决了我的问题

@Override
public void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
    mAdapter = new SearchSTGVAdapter(getActivity(), adsList, (Fragment)this);       
    ptrstgv.setAdapter(mAdapter);

}

之前我把它放在onCreate方法中为了您的信息，我在视图分页器中实现了这种pinterest样式而不是滑动菜单

StaggeredGridView只能正确刷新顶部
