自定义菜单项单击后如何关闭Android菜单？

Question

单击Xamarin Forms Android自定义菜单项后出现问题。

在我的MainActivity类中，我有：

public override void OnActionModeStarted(ActionMode mode)
{
    IMenu menu = mode.Menu;
    menu.Add("To Notes");
    menu.GetItem(0).SetOnMenuItemClickListener(new MyMenuItemOnMenuItemClickListener(this));

    base.OnActionModeStarted(mode);
}

我的处理程序如下：

public class MyMenuItemOnMenuItemClickListener : Java.Lang.Object, IMenuItemOnMenuItemClickListener
{
    private MainActivity mContext;
    public Func<string, Task<string>> EvaluateJavascript { get; set; }

    public MyMenuItemOnMenuItemClickListener(MainActivity activity)
    {
        this.mContext = activity;
    }

    public bool OnMenuItemClick(IMenuItem item)
    {
        //Web is a static class declared elsewhere
        Web.CopyToMainNotes();

        return true;
    }
}

单击“ To Notes”菜单项时，无论OnMenuItemClick处理程序中的菜单如何，菜单都不会消失。

有什么想法吗？预先感谢。

尝试以下代码：（使用ActionMode.finish()）

public override void OnActionModeStarted(ActionMode mode)
{
    IMenu menu = mode.Menu;
    menu.Add("To Notes");
    menu.GetItem(0).SetOnMenuItemClickListener(new MyMenuItemOnMenuItemClickListener(this,mode));

    base.OnActionModeStarted(mode);
}

处理程序

public class MyMenuItemOnMenuItemClickListener : Java.Lang.Object, IMenuItemOnMenuItemClickListener
{
    private MainActivity mContext;
    public Func<string, Task<string>> EvaluateJavascript { get; set; }
    private ActionMode actionMode;

    public MyMenuItemOnMenuItemClickListener(MainActivity activity,ActionMode mode)
    {
        this.mContext = activity;
        this.actionMode=mode;
    }

    public bool OnMenuItemClick(IMenuItem item)
    {
        //Web is a static class declared elsewhere
        Web.CopyToMainNotes();
        //close menu if menu item is clicked
        if(actionMode!=null){
        actionMode.finish()
        }
        return true;
    }
}
