Xamarin Forms Custom View Renderer for TextView Height issue - xamarin.forms

Question

I want to render xamarin forms view control into android textview.
Below customrenderer renders Android TextView on Android device with initial default text.
Now, If I add more text into it, this control would not grow in height but instead becomes scrollable to see the text not visible on screen.
On other way around, if I reduce text content, this control would not reduce in height and occupy the same space and show reduced text content on scree.
Issue : In this case of text change, this label should increase or reduce height on screen for Android. It is working fine on IOS as expected.
BindingText is bindable property to set text for this control.
CopyableLabelRenderer is my custom renderer class for Xamarin Forms
view.
Here is a sample code.
class CopyableLabelRenderer : ViewRenderer
{
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.View> e)
{
base.OnElementChanged(e);
try
{
var label = new TextView(MainApplication.Context);
label.SetTextIsSelectable(true);
label.LinksClickable = true;
label.Text = (e.NewElement as CopyableLabel).BindingText; // this line sets text into this label
SetNativeControl(label);
}
catch (Exception ex)
{
var msg = ex.Message;
}
}
protected override void OnElementPropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
base.OnElementPropertyChanged(sender, e);
if (e.PropertyName.Equals("BindingText"))
{
TextView textView = this.Control as TextView;
textView.Text = (Element as CopyableLabel).BindingText;
}
}
}
Here is a base class,
public class CustomLabel : View
{
public static readonly BindableProperty BindingTextProperty = BindableProperty.Create("BindingText", typeof(string),typeof(View),
string.Empty
);
public string BindingText
{
get
{
return (string)GetValue(BindingTextProperty);
}
set
{
SetValue(BindingTextProperty, value);
}
}
}
