我一直试图将页脚视图添加到MvxExpandableListView的每个组列表中，但未成功。
AddFooterView方法只是添加到整个列表的底部。
我一直在尝试创建一个继承自MvxExpandableListAdapter的自定义适配器，以便我可以尝试自己添加它。 但是，我得到＆＃34; Android.Content.Res.Resources + NotFoundException：资源ID＃0x0＆＃34;当列表加载时，堆栈跟踪看起来好像是使用原始的MvxExpandableListAdapter而不是我创建的新的。
我的活动OnCreate
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.WorkOrderListing);
SetupToolbar();
SetupNavigationMenu(Resource.Id.nav_work_orders);
_listView = FindViewById<MvxExpandableListView>(Resource.Id.listing_workorders);
var adapter = new LoadMoreExpandableListAdapter(this, BindingContext as IMvxAndroidBindingContext);
_listView.SetAdapter(adapter);
}
我的布局文件中的列表视图
<Mvx.MvxExpandableListView
android:id="@+id/listing_workorders"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:dividerHeight="@dimen/expandablelist_divider_height"
android:childDivider="@color/line_grey"
android:contentDescription="WorkOrderListing_ExpandableList"
android:groupIndicator="@null"
local:MvxGroupItemTemplate="@layout/workorderlisting_header"
local:MvxItemTemplate="@layout/workorderlisting_detail"
local:MvxBind="ItemsSource WorkOrderLists; GroupClick GroupClickCommand; ItemClick ItemClickCommand" />
我的适配器，（在尝试添加页脚之前，只是尝试使用最少的代码才能使其正常工作）
public class LoadMoreExpandableListAdapter : MvxExpandableListAdapter
{
#region Constructors
public LoadMoreExpandableListAdapter(Context context) : base(context)
{
}
public LoadMoreExpandableListAdapter(Context context, IMvxAndroidBindingContext bindingContext) : base(context, bindingContext)
{
}
protected LoadMoreExpandableListAdapter(IntPtr javaReference, JniHandleOwnership transfer) : base(javaReference, transfer)
{
}
#endregion
public new View GetChildView(int groupPosition, int childPosition, bool isLastChild, View convertView, ViewGroup parent)
{
object rawItem = this.GetRawItem(groupPosition, childPosition);
return this.GetBindableView(convertView, rawItem, this.ItemTemplateId);
}
public new View GetGroupView(int groupPosition, bool isExpanded, View convertView, ViewGroup parent)
{
object rawGroup = this.GetRawGroup(groupPosition);
return this.GetBindableView(convertView, rawGroup, this.GroupTemplateId);
}
}
我认为问题出现在MvxExpandableListView
的代码块中protected MvxExpandableListAdapter ThisAdapter {
get {
return this.ExpandableListAdapter as MvxExpandableListAdapter;
}
}
