Strange issue with xamarin.forms

Question

The entry field from the view is being populated on the content page. And in the view it is set as IsEnabled=false;. Whenever it is set as disabled the value of the entry is not getting set.

Please take a look at the code below:

    public class DetailsView : ContentView
    {
        public static Entry txtdetailsName;
        public DetailsView()
        { 
            Label lbldetailsName = new Label { Text = Resource.detailsName, FontAttributes = FontAttributes.Bold, Style = (Style)Application.Current.Resources["LabelStyle"] };
            txtdetailsName = new Entry { Style = (Style)Application.Current.Resources["entryStyle"], IsEnabled = false  };


            StackLayout stDetailsName = new StackLayout
            {
                Padding = new Thickness(10, 0, 10, 0),
                Children ={ 
                    lbldetailsName,
                    txtdetailsName
                }
            };
            Content = new StackLayout
            {
                Padding = new Thickness(0, 0, 0, 20),
                Children = {stDetailsName}
            };
        }
    }

In content page:

public TestDetailsPage()
{
    getDetailsData();
}

private async void getDetailsData()
{
    Test test = new Test();
    test = await getTestDetails();
    loadView(test);
}

public async Task<Test> getTestDetails() 
{
    //...
    return Test;
}

public void loadView(Test test)
{
    DetailsView = new DetailsView();
    //DetailsView.txtdetailsName.Text = Test.Name;
    DetailsView.txtdetailsName.Text = "Some Text";
}

But it doesn't seem to set the value. Not sure what is causing the issue.

Edit

I tested the app on three android devices Micromax Canvas (Android version 6.0.1), Asus Zenfone(Android version 4.4.2) and Samsung Galaxy Tab 2 (Android version 4.1.2). On Asus zenfone and Samasung galaxy tab 2, the value for the disabled field is displayed as expected while on Micromax canvas the disabled text-boxes are empty.

Android version could be the issue?

Looks like loadView is possibly not creating DetailsView on the main thread. Can you check to make sure it is? The async void might be swallowing that Exception.

It does create DetailsView. I tested the app on 3 devices(Micromax Canvas (Android version 6.0.1), Asus Zenfone(Android version 4.4.2) and Samsung Galaxy Tab 2 (Android version 4.1.2)) and strangely it worked on two devices(Asus zenfone and Samasung galaxy tab 2). The android version could be the issue? – Arti Apr 28 '16 at 04:58
It certainly could be the Android version. Is your app using the FormsAppCompatActivity? – joe Apr 28 '16 at 13:12
No, MainActivity.cs is inheriting from FormsApplicationActivity – Arti Apr 29 '16 at 04:27
Would you please tell me which field I will have to set to make my pages full screen? – Arti Apr 29 '16 at 12:46
Could you try to inherit from FormsAppCompatActivity to see if that works? Full screen should be [here](http://stackoverflow.com/questions/2868047/fullscreen-activity-in-android). – joe Apr 29 '16 at 18:03
