Answer 1

You can add a HeightRequest in your code like that:

XAML

<StackLayout Orientation="Vertical"  HorizontalOptions="FillAndExpand">
                <Button Name="imageBtn" Text="Has Image" Image="drawable/fb_btn.png" 
                  HeightRequest="56"/>
 </StackLayout>

More info:

1,Your code contain StackLayout ,it also can modify the result.

2,If you want more control over the image size and placement,you can add a tap gesture recognizer to it.

.CS

TapGestureRecognizer tapEvent = new TapGestureRecognizer();
tapEvent.Tapped += Button_Clicked;
imageBtn.GestureRecognizers.Add(tapEvent);

Answer 2

workaround

1.You can use Image control with a tapgesture:

XAML

<Image x:Name="myImage" Source="myPicture.png" HeightRequest="150" WidthRequest="60" BackgroundColor="Red" HorizontalOptions="Center"/>

XAML.CS

TapGestureRecognizer tapEvent = new TapGestureRecognizer();
tapEvent.Tapped += clickedEvent;
myImage.GestureRecognizers.Add(tapEvent);
