I'm making an app in Xamarin Forms and when I deploy it to Android, I get a weird problem. It appears that I have two toolbar items when I only declared one in XAML. Also, I believe this is proper behaviour, but I was wondering if it's possible to not display the navbar title on a lower line and rather display it upper center. Thanks!

In your pages Xaml.cs file:
NavigationPage.SetHasNavigationBar(this, false);

I'm working on Xamarin Project and I don't need navigation bur, I switched it off but now I cant move app content of page
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:prism="http://prismlibrary.com"
prism:ViewModelLocator.AutowireViewModel="True"
xmlns:imgExt="clr-namespace:GulfStar.Xamarin.Extensions"
x:Class="GulfStar.Xamarin.Views.StatusPickerPage"
NavigationPage.HasNavigationBar="False">
<StackLayout>
<StackLayout Orientation="Horizontal" VerticalOptions="Start" >
<Image Source="{imgExt:ImageResource GulfStar.Xamarin.Images.Icon.png}" WidthRequest="70" HeightRequest="70"/>
<Label HorizontalOptions="Center" Margin="0,17,0,0" FontSize="Title">GSI Accountability</Label>
</StackLayout>
</StackLayout>
</ContentPage>
I figured out who it happen
How to remove blue section
Use NavigationPage.SetHasNavigationBar(this, false); to hide the navigation bar.
I figured out how to make that thing disappears
when you navigation to some page does not use Navigation page NavigationService.NavigateAsync("NavigationPage/StatusPickerPage");
Use
NavigationService.NavigateAsync("StatusPickerPage");
And it would not track navigation and its not needed if you have only two pages
The font that I have is too big for the amount of words that I would like to display. Does anyone have any suggestions as to how I can change the font size. I would prefer to be able to do it in the shared code but if it needs a custom renderer then can someone show me how this can be done?
So, if you are using Xamarin.Forms 3.2.0 or above, you can use TitleView property like this:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Xamarin.Forms.Controls.GalleryPages.TitleView">
<NavigationPage.TitleView>
<Label Text="This is my Title" FontSize="12" TextColor="White" />
</NavigationPage.TitleView>
<!-- YOUR CONTENT HERE-->
</ContentPage>
In my xamarin app,I want to add a search bar on top of the page in my tabbed page.
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="Sample.Mobile.Test">
<StackLayout>
<SearchBar></SearchBar>
</StackLayout>
<TabbedPage.Children>
<ContentPage x:Name="tab1" Title="Home">
</ContentPage>
</TabbedPage.Children>
</TabbedPage>
You can use follow this link for the Search bar Implementation

I've inherited a Xamarin project and am not sure why I'm seeing this behavior when trying to work with a CarouselPage.
Using the Prism NavigationService, if I navigate to the carousel page as the "base page", it shows fine, but if I navigate to it as a "sub page" (to push it on the navigation stack?) it doesn't show, though I get no errors.
The problem is that using the navigation method that works doesn't provide me with a back button.
Example:
// this works, but no back button
await _navigationService.NavigateAsync("file:///MenuMasterDetailPage/MenuNavigationPage/MyCarouselPage");
// this doesn't, have back button but no content is shown
await _navigationService.NavigateAsync("MyCarouselPage");
I'm unsure how the master/detail/navigation stuff really works: not sure if my issue is there or if there's something special about a CarouselPage that prevents it from being rendered in the second case.
The MyCarouselPage is as simple as can be while I try to get this to work:
<?xml version="1.0" encoding="utf-8" ?>
<CarouselPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:prism="clr-namespace:Prism.Mvvm;assembly=Prism.Forms"
x:Class="Views.ImageCarouselPage"
effects:BackgroundImageEffect.BackgroundImage="Resources.SignInBackground.png">
<ContentPage>
<StackLayout VerticalOptions="FillAndExpand">
<Image Source="https://s3.amazonaws.com/blah.jpg" Aspect="AspectFit" VerticalOptions="FillAndExpand" />
</StackLayout>
</ContentPage>
<ContentPage>
<StackLayout VerticalOptions="FillAndExpand">
<Image Source="https://s3.amazonaws.com/blah.jpg" Aspect="AspectFit" VerticalOptions="FillAndExpand" />
</StackLayout>
</ContentPage>
</CarouselPage>
(I should note that the background image does display, but the contents of the carousel does not).
Any ideas? Thanks.
Is anyone having trouble with the CalendarView component from XLabs? I have written the XAML code below, tried to run it on my Android device, and it displays just fine, only there's no way to change the current month (I'm expecting a swipe should work), nor can I see any navigation arrows.
Anyone got any idea what's going on?
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:controls="clr-namespace:XLabs.Forms.Controls;assembly=XLabs.Forms"
xmlns:local="clr-namespace:TestXAML"
x:Class="TestXAML.MainPage"
Padding="10">
<controls:CalendarView
x:Name="calendarioConsultas"
HorizontalOptions="Fill"
ShowNavigationArrows="True"
BackgroundColor="Transparent"
NavigationArrowsColor="Black"
/>
</ContentPage>
Ok, I solved it by setting MinDate parameter to 01/01/1970. Turns out that navigation doesn't work unless you specify MinDate or MaxDate.
