Android RecylerView按钮不会触发

我的回收卡上有一个按钮，用于显示

弹出菜单

但是，每当用户单击此按钮时，

popupMenu

不会出现。甚至我在

菜单选项按钮中也放置了一个断点。单击
操作，它不会命中

XML格式的ImageButton

<ImageButton
    android:id="@+id/MoreSettings"
    android:layout_width="40dp"
    android:layout_height="40dp"
    android:layout_alignParentRight="true"
    android:src="@drawable/ic_more_black_24dp" /> 

更新：

活动.cs

public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    var ignored = base.OnCreateView(inflater, container, savedInstanceState);
    var view = this.BindingInflate(Resource.Layout.AView, null);   
    HasOptionsMenu = true;
    toolbar = ((MainView)Activity).SupportActionBar;   
    var recyclerView = view.FindViewById<MvxRecyclerView>(Resource.Id.ARecyclerView);
    if (recyclerView != null)
    {
        recyclerView.HasFixedSize = true;
        recyclerView.Adapter = new RecyclerAdapter((IMvxAndroidBindingContext)BindingContext, Activity);
        var layoutManager = new LinearLayoutManager(Activity);
        recyclerView.SetLayoutManager(layoutManager);
      }
    return view;
}

public override视图OnCreateView（布局、充气机、视图组容器、Bundle savedInstanceState）
{
忽略变量=base.OnCreateView（充气机、容器、savedInstanceState）；
var view=this.BindingInflate（Resource.Layout.AView，null）；
HasOptions菜单=true；
工具栏=（（主视图）活动）；
var recyclerView=view.findviewbyd（Resource.Id.ARecyclerView）；
如果（recyclerView！=null）
{
recyclerView.HasFixedSize=true；
Adapter=new RecyclerAdapter（（IMvxAndroidBindingContext）BindingContext，Activity）；
var layoutManager=新的LinearLayoutManager（活动）；
recyclerView.SetLayoutManager（layoutManager）；
}
返回视图；
}
在您的RecyclerView.Adapter代码中，在OnBindViewHolder方法中添加单击委托时应小心。如果添加为C#匿名函数，则每次视图显示新委托时，都将添加而不是设置

首先，应将此行放置在ViewHolder构造函数方法中：

this.menuOptionsButton = view.FindViewById<ImageButton>(Resource.Id.MoreSettings);

id不同于
MoreOptions
vs
MoreSettings
对不起，是打字错误，我已修复并向我的问题中添加了其他信息。您是否将链接器设置为仅
Sdk程序集
或
Sdk和用户程序集
？链接器属性为
none
@hotstring是否有
RecyclerView.ViewHolder
子类？你能添加你的
RecyclerAdapter.OnCreateViewHolder
override。。。。
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
    var ignored = base.OnCreateView(inflater, container, savedInstanceState);
    var view = this.BindingInflate(Resource.Layout.AView, null);   
    HasOptionsMenu = true;
    toolbar = ((MainView)Activity).SupportActionBar;   
    var recyclerView = view.FindViewById<MvxRecyclerView>(Resource.Id.ARecyclerView);
    if (recyclerView != null)
    {
        recyclerView.HasFixedSize = true;
        recyclerView.Adapter = new RecyclerAdapter((IMvxAndroidBindingContext)BindingContext, Activity);
        var layoutManager = new LinearLayoutManager(Activity);
        recyclerView.SetLayoutManager(layoutManager);
      }
    return view;
}

this.menuOptionsButton = view.FindViewById<ImageButton>(Resource.Id.MoreSettings);

public override void OnBindViewHolder(RecyclerView.ViewHolder holder, int position)
{
    base.OnBindViewHolder(holder, position);
    var optionsButton = ((YourHolder)holder).menuOptionsButton;

    // This avoids adding a Click event more than once
    optionsButton.Click -= this.PopupShow;
    optionsButton.Click += this.PopupShow;
}

private void PopupShow(object sender, EventArgs e)
{
    Toast.MakeText(this.context, "Button clicked", ToastLength.Short).Show();
    var popup = new PopupMenu(_activity, menuOptionsButton );
    popup.MenuInflater.Inflate(Resource.Menu.menu,popup.Menu);
    popup.Show();
}
