当列表为空时,ActionBarPullToRefresh 不起作用
ActionBarPullToRefresh doesn't work when list is empty
我在我的 ListFragment 上使用 Chris Banes ActionBar-PullToRefresh。
一切正常,但 ListView 为空时除外。当 ListView 为空(并且空文本可见)时,虽然我在 theseChildrenArePullable()
.
中设置了 getListView().getEmptyView()
,但下拉刷新功能不起作用
我也试过 allChildrenArePullable()
没用。
来自我的 ListFragment 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);
}
代码来自我的 adapter_lists.xml:
<?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>
所以我使用原生的 SwipeRefreshLayout 解决了这个问题。
要使这项工作正常进行,您需要有自己的看法:
<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>
以及您的 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);
