나는 아주 간단한 레이아웃을 가지고 있지만 내가 전화 할 때 setRefreshing(true)에 onActivityCreated()내 조각, 그것은 처음에 표시되지 않습니다.

새로 고치기 위해 풀을 할 때만 표시됩니다. 왜 처음에 나타나지 않는지 아는 아이디어가 있습니까?

조각 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>

조각 코드 :

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
    }
}
