The gridView doesn`t adjust its height,when I set the footerView gone

[NiaNingXue]

I make the footerView as a loadmore view , When I set the footerView visable or gone ,the GridView cann`t adjust its height to match the screen .here is the code:

        mGridView = (GridViewWithHeaderAndFooter)inflater.inflate(R.layout.fragment_category_detail, container, false);
        mFooterView = new LoadMoreFooterView(mContext);
        mGridView.addFooterView(mFooterView);
        mGridView.setOnScrollListener(mFooterView);
        `mFooterView.setOnLoadMoreListener(this);`

   @Override
    public void onLoadMore() {
        mFooterView.setStatus(LoadMoreFooterView.Status.LOADING);
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                mFooterView.setStatus(LoadMoreFooterView.Status.GONE);
            }
        },3500);
    }
