This is my 3rd day in Xamarin classes and I am really struggling with setting a responsive app background. I am trying to have this structure:
I finally achieve to set a responsive background with AspectFill property which is standing between <RelativeLayout> tags.
But now, I am unable to have the label on the top center of the app due to the <RelativeLayout> tags. The label which I have created for the logo stands on the left side.
I tried to add HorizontalOptions property, but unfortunately, it hasn't affected.
Here are the related xaml codes:
<RelativeLayout Padding="0">
<Image Aspect="AspectFill" Source="background.png" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}" RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Height}">
</Image>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*">
</ColumnDefinition>
<ColumnDefinition Width="*">
</ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*">
</RowDefinition>
<RowDefinition Height="*">
</RowDefinition>
</Grid.RowDefinitions>
<StackLayout Grid.Column="0" Grid.Row="0" HorizontalOptions="">
<Label Text="MENU">
</Label>
</StackLayout>
<StackLayout Grid.Column="1" Grid.Row="0">
<Label Text="LOGO" FontSize="28">
</Label>
</StackLayout>
</Grid>
</RelativeLayout>
My failed result:
Do we have any other alternatives for the <RelativeLayout> which causes a lot of UI problems?
Many thanks to #Jason
The problem has been fixed by adding a new column grid. In other words, there should be 3 columns in total. But, I had added only 2 columns.
Here are my updated xaml codes:
<RelativeLayout Padding="0">
<!-- Background -->
<Image Aspect="AspectFill" Source="background.png" RelativeLayout.WidthConstraint="{ConstraintExpression Type=RelativeToParent, Property=Width}" RelativeLayout.HeightConstraint="{ConstraintExpression Type=RelativeToParent, Property=Height}">
</Image>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*">
</ColumnDefinition>
<ColumnDefinition Width="*">
</ColumnDefinition>
<ColumnDefinition Width="*">
</ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*">
</RowDefinition>
<RowDefinition Height="*">
</RowDefinition>
</Grid.RowDefinitions>
<StackLayout Grid.Column="0" Grid.Row="0" HorizontalOptions="Start">
<Label Text="MENU">
</Label>
</StackLayout>
<StackLayout Grid.Column="1" Grid.Row="0">
<Label Text="LOGO" FontSize="28">
</Label>
</StackLayout>
<StackLayout Grid.Column="2" Grid.Row="0">
</StackLayout>
</Grid>
</RelativeLayout>

I want to make a UI like this:
This UI should correspond to different phone screen sizes.
I started to write this XAML code:
<StackLayout>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Frame BackgroundColor="Transparent"/>
</Grid>
<Grid Margin="20">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid Grid.Row="0">
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10"/>
</Grid>
<Grid Grid.Row="1" Padding="0,40,0,0">
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10"/>
</Grid>
</Grid>
<Entry Grid.Row="0" Grid.Column="1" MaxLength="30" Placeholder="User Name:" ClearButtonVisibility="WhileEditing"/>
<Entry Grid.Row="1" Grid.Column="1" MaxLength="30" Placeholder="Password:" ClearButtonVisibility="WhileEditing" IsPassword="True"/>
<Image Source="User.png" Scale="0.6"/>
<Image Source="Lock.png" Scale="0.6"/>
<Button Text="Login"/>
</StackLayout>
I know that Those images must be in the Grid node above. But I cannot set those Entry and user/pass logos correctly. Those buttons are images in the resource folder.
Please help me to set a UI similar to this image.
One grid is enough, you can remove one.
You can refer to the following code:
<StackLayout BackgroundColor="#1E90FF" Orientation="Vertical">
<Grid Margin="20" >
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10" Grid.Row="0" Grid.ColumnSpan="2" />
<Entry Grid.Row="0" Grid.Column="0" MaxLength="30" Placeholder="User Name:" ClearButtonVisibility="WhileEditing" />
<Image Source="head.png" Scale="0.6" Grid.Row="0" Grid.Column="1"/>
<Frame HeightRequest="30" BackgroundColor="White" CornerRadius="10" Grid.Row="1" Grid.ColumnSpan="2"/>
<Entry Grid.Row="1" Grid.Column="0" MaxLength="30" Placeholder="Password:" ClearButtonVisibility="WhileEditing" IsPassword="True"/>
<Image Source="Lock.png" Scale="0.6" Grid.Row="1" Grid.Column="1"/>
</Grid>
<Button Text="Login"/>
</StackLayout>
The result is:
I have a situation where I need to "overlay" a grouped set of information, presented by way of a Card (inplemented as a ContentView) on top of a portion of the page header, which is defined in a Grid inside of a FlexLayout. The output should resemble something like the following where the header is the portion in red:
The code for the header is as follows:
<!-- Header -->
<FlexLayout
HeightRequest="108"
AlignItems="Center"
Direction="Column"
BackgroundColor="#D92732">
<Grid VerticalOptions="Center" Margin="0, 30, 0, 0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="20"></ColumnDefinition>
<ColumnDefinition Width="40*"></ColumnDefinition>
<ColumnDefinition Width="80*"></ColumnDefinition>
<ColumnDefinition Width="300*"></ColumnDefinition>
<ColumnDefinition Width="80*"></ColumnDefinition>
<ColumnDefinition Width="40*"></ColumnDefinition>
<ColumnDefinition Width="20"></ColumnDefinition>
</Grid.ColumnDefinitions>
<ImageButton Source="Bell.png" Grid.Column="1" BackgroundColor="Transparent"
WidthRequest="37"
HeightRequest="40"
Aspect="AspectFit">
</ImageButton>
<Label
Grid.Column="3"
Text="Payments"
TextColor="#F9F8FA"
FontSize="20"
HeightRequest="40"
HorizontalOptions="Center"
VerticalOptions="Center" VerticalTextAlignment="End">
</Label>
<ImageButton Source="Bell.png" Grid.Column="5" BackgroundColor="Transparent"
WidthRequest="37"
HeightRequest="40"
Aspect="AspectFit">
</ImageButton>
</Grid>
</FlexLayout>
The method I used to solve the problem of having a visual element overlay a portion of another visual element, in this case a Grid overlay a portion of another Grid, is to set the position of the overlay Grid to a specific row and column of the first Grid and then set the Bottom value of the overlay Grid's Margin to a negative number that represents the desired height of the overlay Grid, as seen in the following code and screenshot. Note that I enclosed the overlaid Grid in a Frame which is where I set the negative Bottom Margin value.
<Frame Grid.Row="2" Grid.ColumnSpan="3" Grid.Column="0"
Margin="16,30,16,-310" WidthRequest="343" HeightRequest="300">
<StackLayout HeightRequest="350">

<RowDefinition Height="44*" />

<RowDefinition Height="40*" />
<RowDefinition Height="20*" />
<RowDefinition Height="96*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Label Grid.Row="0"

I have the following image below which I have tried to design in XAML- Xamarin forms.
The xaml code is as follows:
<ListView x:Name="myList" HasUnevenRows="true" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Frame Padding="0,0,0,8" BackgroundColor="#edeeef" BorderColor="#edeeef">
<Frame.Content>
<Frame OutlineColor="Transparent" BackgroundColor="White">
<Frame.Content>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="7*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>
<StackLayout Orientation="Vertical" Grid.Row="0" Grid.Column="0">
<Label Text="{Binding ItemName}"
TextColor="Black"
FontFamily="OpenSans-Light"
FontSize="16"
HorizontalOptions="FillAndExpand"/>
<Label Text="Engine coolant temperature sesnor 1 circuit intermittent (DTC Confirmed)" FontSize="11" HorizontalOptions="StartAndExpand"/>
<StackLayout Orientation="Horizontal">
<Button Text="OBD" />
<Button Text="CUS" />
</StackLayout>
</StackLayout>
<BoxView
VerticalOptions="Fill"
HorizontalOptions="End"
WidthRequest="1"
HeightRequest="5"
Color="Blue"
Grid.Row="0"
Grid.Column="1"/>
<ffsvg:SvgCachedImage
Aspect="AspectFit"
VerticalOptions="Center"
Source="Bin.png"
Grid.Column="2"
Grid.Row="0"
/>
</Grid>
</Frame.Content>
</Frame>
</Frame.Content>
</Frame>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
The issue that I am having is that I am unable to draw the vertical right line separating the content and the square red box on the right.
When I am adding the image, it is adding extra padding on the bottom.
Can someone please help me to align the components properly as in the image above in XamarinForms? Thanks.
Your design is quite messed up and should be cleaned up
Within the ViewCell, you have two nested Frames, which causes the main issue: There is a padding on the inner Frame that and on the outer one, which prevent the separator to take the full height
A nested Grid and StackLayout is most likely not necessary and definitely detrimental for your performance
Suggestions:
Remove the outer Frame and add a Margin to the inner one
Set the Padding of the inner frame to 0
Remove the StackLayout wrapped in the Grid and add the controls to the Grid
Add the Grid.RowSpan and Grid.ColumnSpan for controls that take more height/width in the Grid
Your XAML within the ViewCell will look like this:
<Frame Padding="0"
Margin="5"
BorderColor="Transparent"
BackgroundColor="White"
CornerRadius="10">
<Grid ColumnSpacing="0" RowSpacing="5" Padding="0">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<ColumnDefinition Width="Auto" />
</Grid.ColumnDefinitions>
<Label Text="ItemName"
TextColor="Black"
FontFamily="OpenSans-Light"
FontSize="16"
HorizontalOptions="FillAndExpand"
VerticalOptions="End"
Grid.Column="0"
Grid.Row="0"
Grid.ColumnSpan="2"
Margin="10,10,10,0" />
<Label Grid.Column="0"
Grid.Row="1"
Grid.ColumnSpan="2"
Text="Engine coolant temperature sesnor 1 circuit intermittent (DTC Confirmed)"
FontSize="11"
HorizontalOptions="StartAndExpand"
Margin="10,0,0,0" />
<Button Text="OBD"
VerticalOptions="End"
HorizontalOptions="Start"
Grid.Row="2"
Grid.Column="0"
Margin="10,0,5,10" />
<Button Text="CUS"
VerticalOptions="End"
HorizontalOptions="Start"
Grid.Row="2"
Grid.Column="1"
Margin="0,0,10,10" />
<BoxView VerticalOptions="Fill"
HorizontalOptions="End"
WidthRequest="1"
Color="LightPink"
Margin="0"
Grid.Row="0"
Grid.Column="2"
Grid.RowSpan="3" />
<Image Aspect="AspectFit"
VerticalOptions="Center"
HorizontalOptions="End"
Source="http://lorempixel.com/output/abstract-q-c-200-200.jpg"
Grid.Column="3"
Grid.Row="0"
Grid.RowSpan="3"
Margin="10"/>
</Grid>
</Frame>
And eventually the design looks like that (There is still space for tweaking, but basically that's it. I've changed the colors a bit for better visibility):
Follow this Code.
<Grid Grid.Row="3" Padding="{StaticResource Padding15050}">
<ListView x:Name="ListViewFood" ItemsSource="{Binding FoodList}" HasUnevenRows="True" ItemSelected="OnSelection" >
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Padding="{StaticResource Padding510}">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="0.5*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Controls:Label x:Name="LabelName" Grid.Row="0" Text = "{Binding Name}" Font="17" TextColor="{StaticResource Black}"/>
<Controls:Label x:Name="LabelDescription" Grid.Row="1" Text = "{Binding Description}" Font="15" />
<Controls:Label x:Name="LabelPrice" Grid.Row="2" Text = "{Binding Price}" Font="15" TextColor="{StaticResource YetiBlue}"/>
</Grid>
<Grid Grid.Column="1">
<Controls:RectangleButton Text="Add" Font="Bold,15" VerticalOptions="Start" HorizontalOptions="EndAndExpand" CommandParameter="{Binding Id}" Clicked="RectangleButton_Clicked"/>
</Grid>
</Grid>
</ViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
Design like this.
If you want to add a separate line, you just need to add a BoxView in your xaml with WidthRequest=1.
I always use this solution for separating content.
In your case I would suggest to delete HeightRequest in your BoxView.
I have a grid view and I want to add a button in bottom of my screen
I have used following code:
[![enter image description here][1]][1]
<Grid>[![enter image description here][2]][2]
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="88*"/>
<RowDefinition Height="12*"/>
</Grid.RowDefinitions>
<Grid Grid.Column="0" Grid.Row="0" BackgroundColor="White">
<Grid Grid.Column="1" Grid.Row="0" BackgroundColor="White">
<Grid Grid.Row="1" BackgroundColor="#f24245" HorizontalOptions="FillAndExpand">
<Button Text="Lookupjshgkdfjghkdjfghdkjfhgdlfkjghfk" HorizontalOptions="FillAndExpand" TextColor="White" FontSize="Large" BackgroundColor="#f24245"/>
</Grid>
</Grid>
[1]: https://i.stack.imgur.com/vsEn9.png
[2]: https://i.stack.imgur.com/TazCg.png
Please Add Grid.ColumnSpan="2" Like,
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="88*"/>
<RowDefinition Height="12*"/>
</Grid.RowDefinitions>
<Grid Grid.Column="0" Grid.Row="0" BackgroundColor="White">
<!--Place you code Here-->
</Grid>
<Grid Grid.Column="1" Grid.Row="0" BackgroundColor="White">
<!--Place you code Here-->
</Grid>
<Grid Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" BackgroundColor="#f24245" HorizontalOptions="FillAndExpand">
<Button Text="Lookupjshgkdfjghkdjfghdkjfhgdlfkjghfk" HorizontalOptions="FillAndExpand" TextColor="White" FontSize="Large" BackgroundColor="#f24245"/>
</Grid>
</Grid>
Use VerticalOptions="End"
Example:
<Grid Padding="20" RowSpacing="0">
<Grid.RowDefinitions>
<RowDefinition Height="0.7*" />
<RowDefinition Height="0.3*" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<!-- row 0 -->
<Image Grid.Row="0" Source="icon-76.png" WidthRequest="150" HeightRequest="150" />
<!-- row 1 -->
<StackLayout Grid.Row="2" VerticalOptions="End">
<Button Margin="0,5,0,5" Text="Button at the bottom" BackgroundColor="#4a4acd" TextColor="White" FontAttributes="Bold" />
</StackLayout>
</Grid>
This will give you the following view:
I want to create two buttons in the bottom of the screen using Xamarin.Forms and XAML like the image below:
I've tried to use a GridView but it's getting padding and space from two buttons.
This is how I've tried so far:
<Grid RowSpacing="0"
ColumnSpacing="0"
VerticalOptions="FillAndExpand"
HorizontalOptions="FillAndExpand">
<Grid.RowDefinitions>
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="50*"/>
<ColumnDefinition Width="50*"/>
</Grid.ColumnDefinitions>
<Button Grid.Row="1" Grid.Column="0"
Text="SignUp"
FontSize="Large"/>
<Button Grid.Row="1" Grid.Column="1"
Text="LogIn"
FontSize="Large"/>
</Grid>
Try setting the Padding and Margin properties on the Gridview and Padding on the Buttons to 0. IE,
<GridView Padding="0" Margin="0" ... >
...
<Button Margin="0" ... />
I believe that buttons will not provide the desired design, once it has an inner padding, rounded corners and a mandatory uppercase on text (On Android, at least) that you can't change.
Maybe using expanded labels and gesture Recognizers give you a better fit.
Try this:
<Grid ColumnSpacing="0">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
</Grid.RowDefinitions>
<Label Grid.Column="0" Grid.Row="0"
Text="Signup"
TextColor="White"
FontSize="22"
BackgroundColor="Red"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand"
HorizontalTextAlignment="Center"
VerticalTextAlignment="Center">
<Label.GestureRecognizers>
<TapGestureRecognizer Command="{Binding SignupCommand}"/>
</Label.GestureRecognizers>
</Label>
<Label Grid.Column="1" Grid.Row="0"
Text="Login"
TextColor="White"
FontSize="22"
BackgroundColor="Green"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand"
HorizontalTextAlignment="Center"
VerticalTextAlignment="Center">
<Label.GestureRecognizers>
<TapGestureRecognizer Command="{Binding LoginCommand}"/>
</Label.GestureRecognizers>
</Label>
</Grid>
