java - SwipeRefreshLayout-未将RecyclerView下拉

我有一个RecyclerView和GridLayoutManager，当使用SwipeRefreshLayout时，RecyclerView未被下拉。刷新时如何在工具栏和recyclerview之间产生间隙？

XML：
    
    

    <ProgressBar
        android:id="@+id/progressBar"
        style="?android:attr/progressBarStyleLarge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" />

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <RecyclerView
            android:id="@+id/gridView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

    </android.support.v4.widget.SwipeRefreshLayout>

</FrameLayout>

码：

swipeLayout = (SwipeRefreshLayout) view.findViewById(R.id.swipe_container);
swipeLayout.setOnRefreshListener(this);
swipeLayout.setColorScheme(android.R.color.holo_blue_bright, android.R.color.holo_green_light, android.R.color.holo_orange_light, android.R.color.holo_red_light);

gridView = (RecyclerView) getActivity().findViewById(R.id.gridView);
gridLayoutManager = new GridLayoutManager(getActivity(), 4, GridLayoutManager.VERTICAL, false);
gridView.setLayoutManager(gridLayoutManager);
gridView.setVisibility(View.GONE);
gridView.setHasFixedSize(false);
gridView.setItemAnimator(new DefaultItemAnimator());

最佳答案

您的代码还可以，但是swipeRefreshLayout不会下拉网格视图，而只能下拉自身，对于演示，请检查此video。但是，您可以使用Ulta-Pull-to-Refresh之类的其他库来实现所需的效果！
