Xamrin.Forms Navigation.PopAsync不更改Android上的页面

Question

I have a login button, which when clicked triggers this method:

async void OnLoginButtonClicked(object sender, EventArgs e)
    {
        Navigation.InsertPageBefore(new SiteSelectionPage(), this);
        await Navigation.PopAsync();
    }

On iOS it works fine and the new page and title appear. On Android the title of the page changes from "Login" to "Site Selection" (which is what I want), but the content does not change at all (the username and password Entry boxes are still on the page).

Does anyone know why this is happening specifically on Android?

Answer 1

I can see in your code that you are trying to login the user, so what you can try is changing the App.MainPage in stead of doing that:

Application.Current.MainPage = new NavigationPage(new SiteSelectionPage());

Then if you want to remember if the user is already logged in you can try storing a Setting with this NuGet Package:
