- Creating the master-detail page:
Add a content page and change the code as follows :
RootPage.xaml
<?xml version="1.0" encoding="utf-8"?>
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace: your_NameSpace"
x:Class="your_NameSpace.RootPage">
</MasterDetailPage>
RootPage.xaml.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class RootPage : MasterDetailPage
{
public RootPage()
{
InitializeComponent();
}
}
Add another content page and change the code as follows :
MenuPage.xaml (Design of the actual hamburger menu)
<?xml version="1.0" encoding="UTF-8"?>
<ContentPage BackgroundColor="White"
xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="your_NameSpace.MenuPage">
<ContentPage.Padding >
<OnPlatform x:TypeArguments="Thickness" iOS=" 0 , 20 , 0 , 0" />
</ContentPage.Padding>
<ContentPage.Content>
<StackLayout BackgroundColor="White" Padding ="10 , 30 , 10, 10">
<Button Text="Login" BackgroundColor="White" TextColor="DarkGray" HorizontalOptions="StartAndExpand" Command="{Binding GoHomeCommand}" />
<BoxView HeightRequest="0.5" HorizontalOptions="FillAndExpand" BackgroundColor="Gray"/>
<Button Text="Search" BackgroundColor="White" TextColor="DarkGray" HorizontalOptions="StartAndExpand" Command="{Binding GoSecondCommand}" />
<BoxView HeightRequest="0.5" HorizontalOptions="FillAndExpand" BackgroundColor="Gray"/>
<Button Text="Browse" TextColor="DarkGray" BackgroundColor="White" HorizontalOptions="StartAndExpand" Command="{Binding GoThirdCommand}"/>
<BoxView HeightRequest="0.5" HorizontalOptions="FillAndExpand" BackgroundColor="Gray"/>
</StackLayout>
</ContentPage.Content>
MenuPage.xaml.cs
[XamlCompilation(XamlCompilationOptions.Compile)]
public partial class MenuPage : ContentPage
{
public MenuPage()
{
BindingContext = new MenuPageViewModel();
this.Icon = "yourHamburgerIcon.png"; //only neeeded for ios
InitializeComponent();
}
}
This is where the button click commands of the menu page are bound in
MenuPageViewModel.cs
public class MenuPageViewModel
{
public ICommand GoHomeCommand { get; set; }
public ICommand GoSecondCommand { get; set; }
public ICommand GoThirdCommand { get; set; }
public MenuPageViewModel()
{
GoHomeCommand = new Command(GoHome);
GoSecondCommand = new Command(GoSecond);
GoThirdCommand = new Command(GoThird);
}
void GoHome(object obj)
{
App.NavigationPage.Navigation.PopToRootAsync();
App.MenuIsPresented = false;
}
void GoSecond(object obj)
{
App.NavigationPage.Navigation.PushAsync(new Home()); //the content page you wanna load on this click event
App.MenuIsPresented = false;
}
void GoThird(object obj)
{
App.NavigationPage.Navigation.PushAsync(new ClinicInformation());
App.MenuIsPresented = false;
}
}
- Add the following properties in your application class usually, the name for your application class is App.xaml and App.xaml.cs
Add the following to your App.xaml.cs:
public static NavigationPage NavigationPage { get; private set; }
public static RootPage RootPage;
public static bool MenuIsPresented
{
get
{
return RootPage.IsPresented;
}
set
{
RootPage.IsPresented = value;
}
}
Here RootPage is a static instance of your master-detail page,
NavigationPage is your detail page that you change to change your detail page,
IsMenuPresentend is the bool than when true keeps the MenuPage open and when false closes the same.
After doing all this add this function in your application class and call it in its constructor of your App.Xaml.cs
private void CallMain()
{
var menuPage = new MenuPage();
NavigationPage = new NavigationPage(new Home());
RootPage = new RootPage();
RootPage.Master = menuPage;
RootPage.Detail = NavigationPage;
MainPage = RootPage;
}
In your Android project add the following theme:
values/styles.xml
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MyTheme" parent="MyTheme.Base">
</style>
<style name="DrawerArrowStyle"
parent="@style/Widget.AppCompat.DrawerArrowToggle">
<item name="spinBars">true</item>
<item name="color">#FFFFFF</item>
</style>
<style name="MyTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="colorPrimary">#003399</item>
<item name="colorPrimaryDark">#003399</item>
<item name="colorControlHighlight">#003399</item>
<item name="colorAccent">#012348</item>
<item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>
</resources>
Create a folder named values-v21 and add an XML named styles.xml and add the following code to it :
<?xml version="1.0" encoding="utf-8" ?>
<resources>
<style name="MyTheme" parent="MyTheme.Base">
<item name="android:windowContentTransitions">true</item>
<item name="android:windowAllowEnterTransitionOverlap">true</item>
<item name="android:textAllCaps">false</item>
<item name="android:windowAllowReturnTransitionOverlap">true</item>
<item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
<item name="android:windowSharedElementExitTransition">@android:transition/move</item>
</style>
</resources>
And use the name myTheme as the app theme in all your Android activities.
There you go your hamburger menu is complete in case you have any queries feel free to comment.
Good luck!
Happy Coding.
