How to make the table view scrollable in the following xaml code - xamarin

Question

I want to design a ui page in xaml wherein i want to keep the image ballotInfo.png at the top of the page and the button Next at the bottom. The user should be able to scroll through the rest of the contents. I have tried making the table view scrollable by using scrollview but it ain't working as expected. Kindly help.
Following is the XAML code that am working on.
<AbsoluteLayout>
<RelativeLayout>
<Image Source = "ballotInfo.png" Aspect="Fill" x:Name="headerImage"
RelativeLayout.WidthConstraint = "{ConstraintExpression
Type=RelativeToParent,
Property=Width,
Factor = 1}"
RelativeLayout.HeightConstraint = "{ConstraintExpression
Type = RelativeToParent,
Property=Height,
Factor=0.35}"/>
<StackLayout x:Name="entryLayout" VerticalOptions="FillAndExpand" Padding="0"
RelativeLayout.YConstraint = "{ConstraintExpression
Type=RelativeToView,
ElementName=headerImage,
Property=Height,
Factor=1}">
<TableView Intent="Form" HasUnevenRows = "true" >
<TableView.Root>
<TableSection Title="Local Admin: Ajay" >
<ViewCell>
<StackLayout Orientation="Horizontal" Padding="10,0,10,0" >
<Label Text="Ballot Title" VerticalOptions="Center" TextColor="#a2a1b8" />
<Entry HorizontalOptions="FillAndExpand" FontAttributes="Bold" HorizontalTextAlignment="End" TextColor="#151431" />
</StackLayout>
</ViewCell>
<ViewCell Height="200" >
<StackLayout Orientation="Horizontal" Padding="10,0,10,0">
<Label Text="Ballot Description" VerticalOptions="Center" TextColor="#a2a1b8"/>
<Editor VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" FontSize="Small" TextColor="#151431" />
</StackLayout>
</ViewCell>
<ViewCell>
<StackLayout Orientation="Horizontal" Padding="10,0,10,0">
<Label Text = "Ballot End Date" HorizontalOptions="Center" VerticalOptions="Center" TextColor="#a2a1b8" />
<StackLayout HorizontalOptions="EndAndExpand" >
<DatePicker Date="{x:Static sys:DateTime.Today}" TextColor="#151431" />
</StackLayout>
</StackLayout>
</ViewCell>
<ViewCell >
<StackLayout Orientation="Horizontal" VerticalOptions="Fill" Padding="10,0,10,0" >
<Label Text="No. of Candidates" VerticalOptions="Center" TextColor="#a2a1b8" />
<Entry HorizontalOptions="FillAndExpand" Keyboard="Numeric" HorizontalTextAlignment="End" TextColor="#151431" />
</StackLayout>
</ViewCell>
</TableSection>
</TableView.Root>
</TableView>
</StackLayout>
</RelativeLayout>
<Grid
AbsoluteLayout.LayoutBounds="0.5, 1, 1,AutoSize"
AbsoluteLayout.LayoutFlags="PositionProportional,WidthProportional">
<Button Text="Next"
VerticalOptions="End"
TextColor="White"
FontSize="15"
BackgroundColor="#ff2d55"/>
</Grid>
</AbsoluteLayout>

Answer 1

Replacing the AbsoluteLayout/RelativeLayout for a Grid is a cleaner solution. Here's a template for you:
<Grid
ColumnSpacing="0"
RowSpacing="0">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Grid.Row="0" />
<ScrollView Grid.Row="1">
<StackLayout
Padding="0"
x:Name="entryLayout">
</StackLayout>
</ScrollView>
<Button
Grid.Row="2"
HorizontalOptions="Center"
Text="Next"
/>
</Grid>

I am new to xaml but it seems that ScrollView is not available in xaml, but is available in xamarin. I tried this solution with no success. However, I used ScrollViewer instead which did the job.
