当列表为空时,ActionBarPullToRefresh不起作用

我在我的ListFragment上使用Chris Banes ActionBar-PullToRefresh

除ListView为空外,一切正常。当ListView为空(并且空文本可见)时,拉动刷新功能不起作用,尽管我在getListView().getEmptyView()中设置了theseChildrenArePullable()

我也试过了allChildrenArePullable()但没有效果。

我的 ListFragment

中的代码
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    listAdapter = new ListsAdapter(getActivity(), items);
    setListAdapter(listAdapter);

    Cursor cursor = ListProvider.getInstance().selectAll();
    ArrayList<BaseModel> cursorItems = ListProvider.getInstance().rowsToArrayList(cursor);
    for(BaseModel cursorItem : cursorItems) {
        items.add((ListModel) cursorItem);
    }
}

public void onActivityCreated(Bundle savedState) {
    super.onActivityCreated(savedState);
    registerForContextMenu(getListView());
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View layout = inflater.inflate(R.layout.adapter_lists, container, false);
    return layout;
}

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    getListView().setOnItemLongClickListener(this);

    mPullToRefreshLayout = new PullToRefreshLayout(getActivity());

    ActionBarPullToRefresh.from(getActivity())
            .insertLayoutInto((ViewGroup) view)
            .theseChildrenArePullable(getListView(), getListView().getEmptyView())
            .listener(this)
            .setup(mPullToRefreshLayout);
}

我的 adapter_lists .xml:

中的代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView android:id="@id/android:list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:drawSelectorOnTop="false"/>

    <TextView android:id="@id/android:empty"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:gravity="center"
        android:text="@string/message_my_lists_empty"/>

</LinearLayout>

所以我通过使用原生的SwipeRefreshLayout来解决这个问题。

要实现这一目标,您需要提供自己的观点:

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

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

        <TextView
            android:text="@string/hello_world"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:gravity="center"/>

    </ScrollView>

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

onViewCreated函数中的一些代码:

swipeLayout = (SwipeRefreshLayout) 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);
