我在弹出窗口中填充了一个列表视图。 我正在使用

在选择列表项时，我正在打电话
Rg.plugins.popup.
关闭弹出窗口。
但是有时候我会崩溃：
PopupNavigation.PopAsync(true);
我认为崩溃是因为我的某些用户双击了列表项。 在调用
之前，我是否需要始终检查弹出堆栈计数吗？Android.Runtime.JavaProxyThrowable: Exception of type 'Android.Runtime.JavaProxyThrowable' was thrown. --- End of managed Android.Runtime.JavaProxyThrowable stack trace --- android.runtime.JavaProxyThrowable: System.IndexOutOfRangeException: There is not page in PopupStack at Rg.Plugins.Popup.Services.PopupNavigation.PopAsync (System.Boolean animate) [0x0000c] in :0 at TCRMobile.ViewModels.TicketsListGenericViewModel.OpenTicketTabsPage (TCRMobile.DataObjects.Ticket selectedTicket, System.Int32 mobileID, System.Nullable`1[T] laborMiscTimeMobileID) [0x00000] in :0 at TCRMobile.ViewModels.TicketsListGenericViewModel+<>c__DisplayClass13_0.b__0 () [0x00055] in :0 at TCRMobile.Droid.Services.DialogService+<>c__DisplayClass5_0.b__1 (System.Object sender, Android.Content.DialogClickEventArgs e) [0x0001d] in <5c6ae91b284846f5995b4e735df62b69>:0 at Android.Content.IDialogInterfaceOnClickListenerImplementor.OnClick (Android.Content.IDialogInterface dialog, System.Int32 which) [0x00012] in <1ccf2ea9504d42c08b47c05ee0c5e9f7>:0 at Android.Content.IDialogInterfaceOnClickListenerInvoker.n_OnClick_Landroid_content_DialogInterface_I (System.IntPtr jnienv, System.IntPtr native__this, System.IntPtr native_dialog, System.Int32 which) [0x0000f] in <1ccf2ea9504d42c08b47c05ee0c5e9f7>:0 at (wrapper dynamic-method) System.Object:d515a9d0-d793-4191-a5c6-5e450c1fd743 (intptr,intptr,intptr,int) at mono.android.content.DialogInterface_OnClickListenerImplementor.n_onClick(Native Method) at mono.android.content.DialogInterface_OnClickListenerImplementor.onClick(DialogInterface_OnClickListenerImplementor.java:30) at com.android.internal.app.AlertController$ButtonHandler.handleMessage(AlertController.java:175) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6682) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1534) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1424)
如果更新上述弹出库可以解决此问题？
请说明崩溃的原因和解决方法。
谢谢

尝试此弹出式ViewPage。

这是导航部分。
protected override void OnAppearing()
{
base.OnAppearing();
ImageClose.GestureRecognizers.Add(new TapGestureRecognizer
{
Command = new Command(_ =>
{
PopupNavigation.Instance.PopAsync();
})
});
}
Android
在MainActivity.cs文件中。
Rg.Plugins.Popup.Popup.Init(this, bundle);
IOS
在AppDelegate.cs文件中。
Rg.Plugins.Popup.Popup.Init();
尝试使用此代码。
并且在项目 Rg.Plugins.Popup 1.1.4.158-pre 软件包中已安装。

可能这不是明智的选择。
称呼
await PopUpService.PopUpAll();
服务
public static class PopUpService
{
public static async Task PopUpAll()
{
if (Rg.Plugins.Popup.Services.PopupNavigation.Instance.PopupStack.Any())
{
await Rg.Plugins.Popup.Services.PopupNavigation.Instance.PopAllAsync();
}
}
}
