Custom Android Renderer not fully "working" in SfTabView

Hello SyncFusion,

I'm currently facing an issue on Xamarin.Forms, especially on Xamarin.Android when rendering a CustomView.

I'm using Shimmer from NAXAM (iOS and Android).
Both are working well (Shimmer effect OK), but when I put them in SfTabView (Only in Android),
my CustomView is rendering OK, but shimmering effect does not work.

See screenshot in attachment (my layout WITHOUT SfTabView and WITH SfTabView).

So, is there a way to render my customview correctly in a SfTabView ?

Best regards,

Up please.
Is there a way to call Renderer correctly ?

I already got problem with renderer, that you fixed,
Is there any workaround or anything else that could help me to fix it ?

Hi Cyril, 
Greetings from Syncfusion 
We have checked the Shimmer effect on Xamarin platforms. Shimmer from NAXAM is only available for Xamarin.Android and Xamarin.iOS platforms. But you have mentioned that you are using it on Xamarin.Forms platforms. Could you let us know whether you are using our SfTabView control on Native Android/iOS platform or on Xamarin.Forms platform. 
If Xamarin.Forms platform, have you used Renderer to achieve the Shimmer effect on respective platforms. Could you please provide us the above details along with the sample project or code snippet which you have used on the Renderer. This will be helpful for us to provide better solution on this.

Thanks for this first answer,

I implemented Shimmer effect thanks to Renderer.
I created a ShimmerView (Forms), with a ContentView bindable property.

In each renderer, I created native view associated to CustomView (Forms) content.
Set this native view as Content in the ShimmerView (the NAXAM one, for both platforms).

As you can see in screenshot in attachment,
my renderer is working fine.

As soon as I try to use my view (and so associated renderers) in SfTabView.
Renderer is called, but NEVER shimmered. (Second screenshot where there is no shimmering effect).

What in your SfTabView rendering might cause this problem ?
I ONLY have this problem for Android,
iOS is working well WITH or WITHOUT SfTabView.

Hi Cyril, 
Thanks for the update. 
We have tried to implement the shimmer effect on Xamarin.Forms, while rendering the shimmer on Xamarin.Forms.Android platform we have faced some error on it. Could you please provide us with the issue reproducing sample, it would be helpful for us to provide better solution on this and will save time taken to replicate since we have not tried using Shimmer yet.

I will need to rewrite some part.
I cannot share some code.

I'll let you know soon.
