How can I make my app responsive with this "NEW FEATURE" . I want to have an only light mode for now.
I saw this
UIUserInterfaceStyle style = UIUserInterfaceStyle.Light;
How to activate this on my Xamarin Forms app
You can react to changes in the user interface style by creating two resources: LightTheme and DarkTheme (they will be ResourceDictionaries). Inside them, you can add custom colors. For example:
LightTheme.xaml:
<ResourceDictionary
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="DarkMode.Styles.LightTheme">
<Color x:Key="background">#FFFFFF</Color>
<Color x:Key="mainLabel">#000000</Color>
</ResourceDictionary>
DarkTheme.xaml:
<ResourceDictionary
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="DarkMode.Styles.DarkTheme">
<Color x:Key="background">#000000</Color>
<Color x:Key="mainLabel">#FFFFFF</Color>
</ResourceDictionary>
Then, you have to create a CustomRenderer for the ContentPage element (of course, only for iOS):
[assembly: ExportRenderer(typeof(ContentPage), typeof([YOUR_NAMESPACE].iOS.Renderers.PageRenderer))]
namespace [YOUR_NAMESPACE].iOS.Renderers
{
public class PageRenderer : Xamarin.Forms.Platform.iOS.PageRenderer
{
protected override void OnElementChanged(VisualElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (e.OldElement != null || Element == null)
return;
try
{
SetTheme();
}
catch(Exception ex)
{
}
}
public override void TraitCollectionDidChange(UITraitCollection previousTraitCollection)
{
base.TraitCollectionDidChange(previousTraitCollection);
if (TraitCollection.UserInterfaceStyle != previousTraitCollection.UserInterfaceStyle)
SetTheme();
}
private void SetTheme()
{
if (TraitCollection.UserInterfaceStyle == UIUserInterfaceStyle.Dark)
App.Current.Resources = new DarkTheme();
else
App.Current.Resources = new LightTheme();
}
}
}
More information.
You can react to mode changes by following the previous comment. If you want to set the mode inside your app, you can do so by setting Window.OverrideUserInterfaceStyle in your AppDelegate.cs for instance,
Window.OverrideUserInterfaceStyle = UIUserInterfaceStyle.Dark;

I'm trying to implement Darkmode for Android by using the new AppThemeBinding. It works fine for Android and iOS but i do not have a clue on how to implement it for custom renderers or custom styles.
For example i got a custom Stepper renderer which looks something like this:
protected override void OnElementChanged(ElementChangedEventArgs<Stepper> e)
{
base.OnElementChanged(e);
if (Control != null)
{
Android.Widget.Button buttonDown = (Android.Widget.Button)Control.GetChildAt(0);
Android.Widget.Button buttonUp = (Android.Widget.Button)Control.GetChildAt(1);
if(e.NewElement != null)
{
//Button Down
buttonDown.SetBackgroundResource(Resource.Drawable.button_bg_left);
buttonDown.LayoutParameters = new LinearLayout.LayoutParams(DpToPixel(50), DpToPixel(33));
buttonDown.SetPadding(0,0,0,0);
buttonDown.SetTextColor(Android.Graphics.Color.ParseColor("#007bff"));
//Button Up
buttonUp.SetBackgroundResource(Resource.Drawable.button_bg_right);
buttonUp.LayoutParameters = new LinearLayout.LayoutParams(DpToPixel(50), DpToPixel(33));
buttonUp.SetPadding(0, 0, 0, 0);
buttonUp.SetTextColor(Android.Graphics.Color.ParseColor("#007bff"));
}
}
}
I'm setting a background resource which is a .xml file and looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#FFFFFF"/>
<stroke android:width="1dp" android:color="#007bff" />
<corners
android:topLeftRadius="5dp"
android:bottomLeftRadius="5dp"/>
</shape>
Since the AppThemeBinding is a Markup Extension and works inside .xaml files, i have no clue how i could implement color changes for my android specific renderers?
How could i go about changing the color of my custom shape for Light/Darkmode?
You can Detect the current system theme in the renderer and then set the corresponding color:
class MyStepperRenderer : StepperRenderer
{
public MyStepperRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs<Stepper> e)
{
base.OnElementChanged(e);
OSAppTheme currentTheme = Xamarin.Forms.Application.Current.RequestedTheme;
if (currentTheme == OSAppTheme.Light)
{
//
}
else
{
//
}
}
}
So I have a WebView in my Xamarin Forms application, but I want to make changes to my iOS WebView by creating a custom renderer like recommended here: https://forums.xamarin.com/discussion/129626/how-does-one-implement-wkwebview-ios-in-a-cross-platform-application
I'm not sure how to alter my XAML file though, to call my custom renderer for iOS, and the normal WebView for Android. Currently my XAML file looks like this:
<WebView Source="{Binding StartUrl}"
Navigated="OnBrowserNavigated"
Navigating="OnBrowserNavigating"
AbsoluteLayout.LayoutFlags="All"
AbsoluteLayout.LayoutBounds="0.5, 0.5, 1, 1"/>
Which is using the keyword WebView (Xamarin.Forms.WebView). But if I create a custom renderer for iOS using this method:
// Create a new class:
public class MyWebView : WebView
{
public static readonly BindableProperty UrlProperty = BindableProperty.Create(...);
...
}
// Create custom renderer:
[assembly: ExportRenderer(typeof(MyWebView), typeof(MyWebViewRenderer))]
namespace WKWebViewDemo.iOS
{
...
}
How am I supposed to call this renderer like the page says to
<StackLayout>
<local:MyWebView Url="https://www.microsoft.com" VerticalOptions="FillAndExpand"/>
</StackLayout>
AND still call the Xamarin.Forms.WebView for android like my XAML page is doing right now?
As the Url property is which you defined in your MyWebView ,if you delete the MyWebView class,it will throw not defined error.
if you want to use Source property both in Android and ios,you could not defined a custom webview,and use the WebView in the renderer directly in ios like :
// Create custom renderer:
[assembly: ExportRenderer(typeof(WebView), typeof(MyWebViewRenderer))]
namespace WKWebViewDemo.iOS
{
public class MyWebViewRenderer : ViewRenderer<WebView, WKWebView>
{
WKWebView _wkWebView;
protected override void OnElementChanged(ElementChangedEventArgs<WebView> e)
{
base.OnElementChanged(e);
if (Control == null)
{
var config = new WKWebViewConfiguration();
_wkWebView = new WKWebView(Frame, config);
SetNativeControl(_wkWebView);
}
if (e.NewElement != null)
{
Control.LoadRequest(new NSUrlRequest(new NSUrl(((UrlWebViewSource)Element.Source).Url)));
}
}
}
}
<WebView Source="{Binding StartUrl}"
Url="{Binding StartUrl}"
...>
So this actually did work, the iOS WebView worked well, but the way I want to remove the Url and use "Source" for both is this.
namespace Apm.Mobile.Core.Controls
{
public class BetterWebView : WebView
{
public static readonly BindableProperty UrlProperty = BindableProperty.Create(
propertyName: "Source", // This is now source instead of Url
returnType: typeof(string),
declaringType: typeof(BetterWebView),
defaultValue: default(string));
public new string Source // This string is now Source instead of Url
{
get { return (string)GetValue(UrlProperty); }
set { SetValue(UrlProperty, value); }
}
}
}
I implement TabbedPage with 3 tabs like the following picture.
On top of these 3 tabs, I am trying to set a title, which will be common for all the 3 tabs. Tried title property of tabbedpage, but not worked.
MyTabbedpage.xaml
<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:Myapp;assembly=Myapp"
BarBackgroundColor="#1C7DB4"
BarTextColor="White"
x:Class="Myapp.MyTabbedPage">
</TabbedPage>
MyTabbedpage.xaml.cs
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
namespace Myapp
{
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MyTabbedPage : TabbedPage
{
public MyTabbedPage(bool value)
{
InitializeComponent();
Children.Add(new Topics());
Children.Add(new Group());
Children.Add(new Menu());
}
protected override bool OnBackButtonPressed()
{
return false;
}
}
}
Please suggest a solution.
I don't think you can do it without a custom renderer.
You may try this prebuilt form control - TabView - found at:
https://github.com/gruan01/XFControls
You can find it also on NuGet.
You can set image onto the tabs and other enhancements.
But I strongly recommend a custom renderer as a final solution.
public class MainPageCS : TabbedPage
{
public MainPageCS ()
{
var navigationPage = new NavigationPage (new SchedulePageCS ());
navigationPage.Icon = "schedule.png";
navigationPage.Title = "Schedule";
Children.Add (new TodayPageCS ());
Children.Add (navigationPage);
}
}
This is the code snippet from the official documentation. On line number 7 you can see how the title is set.
After you edited your question, it seems that you want to wrap your TabbedPage by a NavigationPage and set a Title for the NavigationPage. Example:
new NavigationPage(new MyTabbedPage()) { Title = "Common Title" };
Alternatively, one of your TabbedPage children can be a NavigationPage as well, depends on your needs.
I am using masterdetail page within this page i am using tabbed page now i want to show toolbar icon and search bar on the top of page.i am able to place toolbar icon but struggling with search bar.how to place it at the top its behavior should match with the search bar in whatsapp app and in youtube app
The WhatsApp search bar is just that, a SearchBar control which you can add to your XAML layout as follows:
<StackLayout>
<SearchBar Placeholder="Search" Text="{Binding Filter}" />
<ListView ItemSource="{Binding Items}">
...
</ListView>
</StackLayout>
Ensure you have a backing property for the filter. You can use the setter of this property to intercept people filtering the data and filter the Items property accordingly.
The YouTube search behaves a bit differently. The toolbar item pops a new screen modally where the search is handled similar to a UISearchController (on iOS). There is no Xamarin Forms drop-in control (that I'm aware of) that does this for you so you'll probably have to roll your own.
We can create a custom renderer on both Xamarin.iOS and Xamarin.Android to accomplish it.
Here's a sample application for reference:
https://github.com/brminnick/GitTrends
And here's a blog post that shows how to add a search bar to a Xamarin.Forms app for both Xamarin.iOS & Xamarin.Android: https://www.codetraveler.io/2019/08/10/adding-a-search-bar-to-xamarin-forms-navigationpage/
App.cs
Use a Xamarin.Forms Platform-Specific to use LargeTitles on the Xamarin.iOS app.
using Xamarin.Forms.PlatformConfiguration;
using Xamarin.Forms.PlatformConfiguration.iOSSpecific;
public class App : Xamarin.Forms.Application
{
public App()
{
var navigationPage = new Xamarin.Forms.NavigationPage(new MyContentPage());
navigationPage.On<iOS>().SetPrefersLargeTitles(true);
MainPage = navigationPage;
}
}
ISearchPage Interface
Create an Interface that can be used across the Xamarin.Forms, Xamarin.Android and Xamarin.iOS projects.
public interface ISearchPage
{
void OnSearchBarTextChanged(in string text);
event EventHandler<string> SearchBarTextChanged;
}
Xamarin.Forms Page
public class MyContentPage : ContentPage, ISearchPage
{
public MyContentPage()
{
SearchBarTextChanged += HandleSearchBarTextChanged
}
public event EventHandler<string> SearchBarTextChanged;
public void OnSearchBarTextChanged(in string text) => SearchBarTextChanged?.Invoke(this, text);
void HandleSearchBarTextChanged(object sender, string searchBarText)
{
//Logic to handle updated search bar text
}
}
iOS Custom Renderer
using System.Collections;
using System.Collections.Generic;
using System.Linq;
using UIKit;
using MyNamespace;
using MyNamespace.iOS;
using Xamarin.Forms;
using Xamarin.Forms.Platform.iOS;
[assembly: ExportRenderer(typeof(MyContentPage), typeof(SearchPageRenderer))]
namespace MyNamespace.iOS
{
public class SearchPageRenderer : PageRenderer, IUISearchResultsUpdating
{
readonly UISearchController _searchController;
public SearchPageRenderer()
{
_searchController = new UISearchController(searchResultsController: null)
{
SearchResultsUpdater = this,
DimsBackgroundDuringPresentation = false,
HidesNavigationBarDuringPresentation = false,
HidesBottomBarWhenPushed = true
};
_searchController.SearchBar.Placeholder = string.Empty;
}
public override void ViewDidAppear(bool animated)
{
base.ViewDidAppear(animated);
if (ParentViewController.NavigationItem.SearchController is null)
{
ParentViewController.NavigationItem.SearchController = _searchController;
DefinesPresentationContext = true;
//Work-around to ensure the SearchController appears when the page first appears https://stackoverflow.com/a/46313164/5953643
ParentViewController.NavigationItem.SearchController.Active = true;
ParentViewController.NavigationItem.SearchController.Active = false;
}
}
public override void ViewWillDisappear(bool animated)
{
base.ViewWillDisappear(animated);
ParentViewController.NavigationItem.SearchController = null;
}
public void UpdateSearchResultsForSearchController(UISearchController searchController)
{
if (Element is ISearchPage searchPage)
searchPage.OnSearchBarTextChanged(searchController.SearchBar.Text);
}
}
}
Xamarin.Android Menu XML
In the Xamarin.Android project, in the Resources folder, create a new folder called menu (if one doesn't already exist).
Note: the folder, menu, has a lowercase 'm'
In the Resources > menu folder, create a new file called MainMenu.xml.
Open Resources > menu > MainMenu.xml
In MainMenu.xml add the following code:
<?xml version="1.0" encoding="utf-8" ?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/ActionSearch"
android:title="Filter"
android:icon="#android:drawable/ic_menu_search"
app:showAsAction="always|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>
Xamarin.Android CustomRenderer
Uses the Plugin.CurrentActivity NuGet Package.
using Android.Content;
using Android.Runtime;
using Android.Support.V7.Widget;
using Android.Text;
using Android.Views.InputMethods;
using Plugin.CurrentActivity;

{
}
protected override void OnAttachedToWindow()
{
base.OnAttachedToWindow();
if (Element is ISearchPage && Element is Page page && page.Parent is NavigationPage navigationPage)
{
//Workaround to re-add the SearchView when navigating back to an ISearchPage, because Xamarin.Forms automatically removes it
navigationPage.Popped += HandleNavigationPagePopped;

}
}
//Adding the SearchBar in OnSizeChanged ensures the SearchBar is re-added after the device is rotated, because Xamarin.Forms automatically removes it

{
base.OnSizeChanged(w, h, oldw, oldh);
if (Element is ISearchPage && Element is Page page && page.Parent is NavigationPage navigationPage && navigationPage.CurrentPage is ISearchPage)
{
AddSearchToToolbar(page.Title);
}
}
protected override void Dispose(bool disposing)
{
if (GetToolbar() is Toolbar toolBar)
toolBar.Menu?.RemoveItem(Resource.Menu.MainMenu);
base.Dispose(disposing);
}
//Workaround to re-add the SearchView when navigating back to an ISearchPage, because Xamarin.Forms automatically removes it
void HandleNavigationPagePopped(object sender, NavigationEventArgs e)
{
if (sender is NavigationPage navigationPage
&& navigationPage.CurrentPage is ISearchPage)
{
AddSearchToToolbar(navigationPage.CurrentPage.Title);
}
}
void AddSearchToToolbar(string pageTitle)
{
if (GetToolbar() is Toolbar toolBar
&& toolBar.Menu?.FindItem(Resource.Id.ActionSearch)?.ActionView?.JavaCast<SearchView>().GetType() != typeof(SearchView))
{
toolBar.Title = pageTitle;
toolBar.InflateMenu(Resource.Menu.MainMenu);
if (toolBar.Menu?.FindItem(Resource.Id.ActionSearch)?.ActionView?.JavaCast<SearchView>() is SearchView searchView)
{
searchView.QueryTextChange += HandleQueryTextChange;
searchView.ImeOptions = (int)ImeAction.Search;
searchView.InputType = (int)InputTypes.TextVariationFilter;
searchView.MaxWidth = int.MaxValue; //Set to full width - http://stackoverflow.com/questions/31456102/searchview-doesnt-expand-full-width
}
}
}
void HandleQueryTextChange(object sender, SearchView.QueryTextChangeEventArgs e)
{
if (Element is ISearchPage searchPage)
searchPage.OnSearchBarTextChanged(e.NewText);
}
Toolbar GetToolbar() => CrossCurrentActivity.Current.Activity.FindViewById<Toolbar>(Resource.Id.toolbar);
}
}

How to include view in NavigationBar of Xamarin Forms?
install or update Android support repository, google play service and Google USB driver
if you'r using shell app you can use Shell.TitleView instead of Navigation.TitleView as the following :
<Shell.TitleView>
<SearchBar x:Name="search" Margin="10,10,10,10"
HorizontalOptions="FillAndExpand"/>
</Shell.TitleView>
There are a few good examples already of how to create a "custom control" by -
Deriving a Class from View or an existing built-in control and then creating a custom renderer for it per platform.
http://blog.xamarin.com/using-custom-controls-in-xamarin.forms-on-android/
http://developer.xamarin.com/guides/cross-platform/xamarin-forms/custom-renderer/
I want to create a "compound custom control OR usercontrol" which contains multiple elements which are defined in XAML (in the shared code), and then customised with a renderer (to say tweak the styling per platform).
Does anyone have an example of doing this please? A simple example with a view that has a bindable label and an entry box should be enough to show the main principles.
Here is what I have so far -
Defined a ContentView to represent our usercontrols layout and contents.
<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="News.Forms.VisualNewsContentView">
<ContentView.Content>
<StackLayout>
<Label x:Name="MyLabel" Text="Label"></Label>
<Entry x:Name="MyEntry" Text="Entry"></Entry>
</StackLayout>
</ContentView.Content>
</ContentView>
with codebehind -
public partial class VisualNewsContentView : ContentView
{
public VisualNewsContentView ()
{
InitializeComponent ();
}
// Not sure if I need this to access Entry ...
public Entry GetEntry ()
{
return MyEntry;
}
}
Add an Android Custom Renderer for that ContentView, how do I access and customise natively parts / controls of the ContentView?
[assembly:ExportRenderer (typeof(VisualNewsContentView), typeof(VisualNewsRenderer))]
namespace News.Forms.Android
{
public class VisualNewsRenderer: ViewRenderer
{
public VisualNewsRenderer () { }
protected override void OnModelChanged (VisualElement oldModel, VisualElement newModel)
{
base.OnModelChanged (oldModel, newModel);
if (newModel != null) {
VisualNewsContentView newsContentView = newModel as VisualNewsContentView;
// i.e. How could I get hold of EditText etc so I could natively customise its appearance? When you use a built in renderer like EntryRenderer you can use Control to access native control.
Console.WriteLine (newsContentView.GetLabel ().Text);
EditText ed = (EditText)newsContentView.GetEntry ().???
}
}
}
}
Just can't quite get the pieces together to work, the ContentView seems to render fine on page but cannot work out how to access its Child Native controls in the viewrenderer.
Be nice to also show how you can use Binding for the Label and Entry Text values.
I do not want to have to define a custom renderer for each single label / entry etc of the usercontrol.
Is this what you meant?
Some properties to access the Xamarin.Forms controls:
public partial class VisualNewsContentView : ContentView
{
public VisualNewsContentView()
{
InitializeComponent();
}
public Label Label
{
get
{
return MyLabel;
}
set
{
MyLabel = value;
}
}
public Entry Entry
{
get
{
return MyEntry;
}
set
{
MyEntry = value;
}
}
}
Some magic inside the Renderer to customize the controls on the page:
[assembly:ExportRenderer (typeof(VisualNewsContentView), typeof(VisualNewsRenderer))]
namespace News.Forms.Android
{
public class VisualNewsRenderer: ViewRenderer
{
public VisualNewsRenderer () { }
protected override void OnModelChanged (VisualElement oldModel, VisualElement newModel)
{
base.OnModelChanged (oldModel, newModel);
if (newModel != null) {
VisualNewsContentView newsContentView = newModel as VisualNewsContentView;
newsContentView.Label.Text = "It´s some kind of..";
newsContentView.Entry.Text = "MAGIC!";
newsContentView.Entry.BackgroundColor = Color.Blue;
newsContentView.Entry.RotationX = 180;
newsContentView.Entry.Focus();
}
}
}
}
EDIT:
I don't know if it's possible to map your controls from the XAML-page to native controls. You could add the controls which you want to customize natively # the renderer.
[assembly:ExportRenderer (typeof(VisualNewsContentView), typeof(VisualNewsRenderer))]
namespace News.Forms.Android
{
public class VisualNewsRenderer: NativeRenderer
{
public VisualNewsRenderer () { }
protected override void OnModelChanged (VisualElement oldModel, VisualElement newModel)
{
base.OnModelChanged (oldModel, newModel);
if (newModel != null) {
LinearLayout layout = new LinearLayout (Application.Context);
layout.Orientation = Orientation.Vertical;
TextView tv = new TextView (Application.Context);
tv.Ellipsize = TextUtils.TruncateAt.Middle;
tv.Text = "It´s some kind of..";
EditText et = new EditText (Application.Context);
et.SetTextColor (Graphics.Color.Chocolate);
et.Text = "MAGIC!";
layout.AddView (tv);
layout.AddView (et);
SetNativeControl (layout);
}
}
}
}
But like this you won't be using your ContentView.. I'm sorry, I have nothing better than this..
My solution for customizing compound user control is make a custom control for each control used in compound user control.
For example, which this control:
<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" x:Class="News.Forms.VisualNewsContentView">
<ContentView.Content>
<StackLayout>
<Label x:Name="MyLabel" Text="Label"></Label>
<Entry x:Name="MyEntry" Text="Entry"></Entry>
</StackLayout>
</ContentView.Content>
</ContentView>
I will do something like this:
<ContentView xmlns="http://xamarin.com/schemas/2014/forms" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:CustomControls="clr-namespace:App.CustomControls;assembly=App" x:Class="News.Forms.VisualNewsContentView">
<ContentView.Content>
<CustomControls:StackLayout>
<CustomControls:Label x:Name="MyLabel" Text="Label"></CustomControls:Label>
<CustomControls:Entry x:Name="MyEntry" Text="Entry"></CustomControls:Entry>
</CustomControls:StackLayout>
</ContentView.Content>
</ContentView>
Example class for CustomControls:StackLayout is:
(in StackLayout.cs)
using Xamarin.Forms;
namespace App.CustomControls
{
public class StackLayout : Xamarin.Forms.StackLayout
{
}
}
(in StackLayoutRenderer.cs for android project)
[assembly: ExportRenderer(typeof(App.CustomControls.StackLayout), typeof(App.Droid.CustomRenderers.StackLayoutRenderer))]
namespace App.Droid.CustomRenderers.MapView
{
public class StackLayoutRenderer : ViewRenderer<StackLayout, Android.Widget.LinearLayout>
{
protected override void OnElementChanged(ElementChangedEventArgs<StackLayout> e)
{
base.OnElementChanged(e);
}
}
}
