Answer 1

in your portable project add this control

 public class PlaceholderEditor : Editor
{
    public static readonly BindableProperty PlaceholderProperty =
        BindableProperty.Create("Placeholder", typeof(string), typeof(string), "");

    public PlaceholderEditor()
    {
    }

    public string Placeholder
    {
        get
        {
            return (string)GetValue(PlaceholderProperty);
        }

        set
        {
            SetValue(PlaceholderProperty, value);
        }
    }       
}

in your android project add this renderer:

[assembly: ExportRenderer(typeof(PlaceholderEditor), typeof(PlaceholderEditorRenderer))]
namespace Tevel.Mobile.Packages.Droid
{


public class PlaceholderEditorRenderer : EditorRenderer
{ 

public PlaceholderEditorRenderer() {  }

    protected override void OnElementChanged(ElementChangedEventArgs e)
    {
        base.OnElementChanged(e);

        if (e.NewElement != null)
        {
            var element = e.NewElement as PlaceholderEditor;

            this.Control.Background = Resources.GetDrawable(Resource.Drawable.borderEditText);

            this.Control.Hint = element.Placeholder;
        }
    }

    protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        base.OnElementPropertyChanged(sender, e);

        if (e.PropertyName == PlaceholderEditor.PlaceholderProperty.PropertyName)
        {
            var element = this.Element as PlaceholderEditor;
            this.Control.Hint = element.Placeholder;
        }
    }
}
}

in your Resources > drawable add an XML file borderEditText.xml

Xaml: Header - xmlns:ctrls="clr-namespace:my control namespace;assembly= my assembly" control:
