reaching a page from xamarin.forms inside android project - xamarin

Question

I'm working on an android app with xamarin. I made tabbed pages. For the second page, i want to show the camerastream from my android camera. For that, some sample code said me I need to use a textureView inside the android part of the app, but that textureview needs to be putted on that second page. Whenever I try to reach a Stacklayout inside that Page, the following error shows up: 'Page1.camera' is inaccessible due to its protection level.
Using x:FieldModifier="public" inside that stacklayout doesn't work either.
Here is the structure of my code to make it more clear
Here I make the tabbed pages:
MainPage = new TabbedPage
{
Children = {
new MainPage(),
new Page1(),
new Page2()
}
};
Inside that Page1 i have this:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="App4.Page1"
Title="Licht">
<StackLayout x:Name="camera" x:FieldModifier="public" Orientation="Vertical">
</StackLayout>
</ContentPage>
And inside the MainActivity.cs i have this where i have to access the camera.
_textureView = new TextureView(Page1.camera);
And this is the structure of my app
And this is the structure of my app

Using x:FieldModifier="public" inside that stacklayout doesn't work either.
I have tried x:FieldModifier="public"in xamarin form, even though I use x:FieldModifier="public", the "camera" property is still private. This feature is not useful.
As far as I know there is no way to access "camera" inside MainActivity.cs in Xamarin form.
As a workaround you can design a page render for android platform and create a TextureView in your page render code.
how to create a page render
_textureView = new TextureView(Page1.camera);
BTW to initialize TextureView you need the object that implements the ISurfaceTextureListener interface at android platform.
public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity,ISurfaceTextureListener
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
global::Xamarin.Forms.Forms.Init(this, bundle);
TextureView textureView = new TextureView(this);
textureView.SurfaceTextureListener = this;
LoadApplication(new App());
}
public void OnSurfaceTextureAvailable(SurfaceTexture surface, int width, int height)
{
//start
}
public bool OnSurfaceTextureDestroyed(SurfaceTexture surface)
{
//stop
}
public void OnSurfaceTextureSizeChanged(SurfaceTexture surface, int width, int height)
{
throw new NotImplementedException();
}
public void OnSurfaceTextureUpdated(SurfaceTexture surface)
{
throw new NotImplementedException();
}
}
Please follow the TextureView guide for Android.
