android - SwipeRefreshLayout setRefreshing() 最初不显示指示器

Question

我有一个非常简单的布局，但是当我在 fragment 的 onActivityCreated() 中调用 setRefreshing(true) 时，它最初不会显示。

它只在我拉动刷新时显示。任何想法为什么它最初没有出现？

fragment xml:

<android.support.v4.widget.SwipeRefreshLayout
    android:id="@+id/swipe_container"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

        </RelativeLayout>


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

fragment 代码:

public static class LinkDetailsFragment extends BaseFragment implements SwipeRefreshLayout.OnRefreshListener {

    @InjectView(R.id.swipe_container)
    SwipeRefreshLayout mSwipeContainer;

    public static LinkDetailsFragment newInstance(String subreddit, String linkId) {
        Bundle args = new Bundle();
        args.putString(EXTRA_SUBREDDIT, subreddit);
        args.putString(EXTRA_LINK_ID, linkId);

        LinkDetailsFragment fragment = new LinkDetailsFragment();
        fragment.setArguments(args);

        return fragment;
    }

    public LinkDetailsFragment() {
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        mSwipeContainer.setOnRefreshListener(this);
        mSwipeContainer.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);
        mSwipeContainer.setRefreshing(true);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        final View rootView = inflater.inflate(R.layout.fragment_link_details, container, false);
        ButterKnife.inject(this, rootView);
        return rootView;
    }

    @Override
    public void onRefresh() {
        // refresh
    }
}

面临同样的问题。我的解决方案 -

mSwipeRefreshLayout.post(new Runnable() {
    @Override
    public void run() {
        mSwipeRefreshLayout.setRefreshing(true);
    }
});
