Xamarin表单：选择特定标签时如何显示全屏页面

Question

I have a tabbed main application with Xamarin Forms.

I am looking to open a Content page in full screen (without tabs and titles) when switching to a specific tab. I am able to obtain the desired behaviour when I press a button like this:

await Navigation.PushModalAsync(new DashboardPage());

Though i'm not sure how to make it to automatically open when switching to that specific tab.

Any help will be so much appreciated,

Thanks!

Answer 1

I managed to obtain it by adding the following to the tab page class:

    protected override void OnAppearing()
    {
        base.OnAppearing();
        Navigation.PushModalAsync(new DashboardPage());
    }

    protected override void OnDisappearing()
    {
        base.OnDisappearing();
        // move on a different tab to avoid infinite loop when back button is pressed
        var masterPage = this.Parent as TabbedPage;
        masterPage.CurrentPage = masterPage.Children[0];
    }

Probably not the most elegant way but it does the job
