ViewCell - image fill, text on bottom - xamarin

Question

The layout i want is like this: http://imgur.com/etb9ZKZ
I want the image (illustrated with the color green) to fill the entire layoutcontol. On top of image positioned at the bottom with full width i want a textbox/label to put a title. The title view should have a black semi-transparent background.
This is the best i've got (the code below), but it has a few issues:
#1 - The text doesnt wrap like it is suppose to. It just cuts the sentence, like the rest is going off screen.
#2 - The image doesnt scale to the width of the container.
Label lblTitle = new Label()
{
BackgroundColor = new Color(0, 0, 0, 0.8),
LineBreakMode = LineBreakMode.WordWrap,
FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label))
};
lblTitle.SetBinding(Label.TextProperty, "headline");
Image imgBanner = new Image()
{
/*
HorizontalOptions = LayoutOptions.Fill,
VerticalOptions = LayoutOptions.End,
Aspect = Aspect.Fill
*/
};
imgBanner.SetBinding(Image.SourceProperty, "ImageUrlSource");
AbsoluteLayout.SetLayoutFlags(lblTitle, AbsoluteLayoutFlags.PositionProportional | AbsoluteLayoutFlags.WidthProportional);
AbsoluteLayout.SetLayoutBounds(lblTitle, new Rectangle(0, 1, 1, AbsoluteLayout.AutoSize));
AbsoluteLayout.SetLayoutFlags(imgBanner, AbsoluteLayoutFlags.SizeProportional);
AbsoluteLayout.SetLayoutBounds(imgBanner, new Rectangle(0, 0, 1, 1));
AbsoluteLayout layout = new AbsoluteLayout()
{
HorizontalOptions = LayoutOptions.Fill,
Children =
{
imgBanner,
lblTitle
}
};
View = layout;

You should use Grid instead.
Label lblTitle = new Label()
{
BackgroundColor = new Color(0, 0, 0, 0.8),
LineBreakMode = LineBreakMode.WordWrap,
FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label))
};
lblTitle.SetBinding(Label.TextProperty, "headline");
Image imgBanner = new Image()
{
/*
HorizontalOptions = LayoutOptions.Fill,
VerticalOptions = LayoutOptions.End,
Aspect = Aspect.Fill
*/
};
imgBanner.SetBinding(Image.SourceProperty, "ImageUrlSource");
//=========== Addition Start Here ============//
Grid grid = new Grid();
grid.RowDefinitions =
{
new RowDefinition{ Height=new GridLength(200,GridUnitType.Absolute) },
new RowDefinition{ Height=new GridLength(30,GridUnitType.Absolute},
}
grid.Children.Add(imgBanner,0,1,0,2); //two rowspan
// == .Add(imgBanner,column,column+columnspan,row,row+rowspan)
grid.Children.Add(lblTitle,0,1,1,2); //one rowspan
View = grid;
