Xamarin Forms thread background

Question

Xamarin Forms thread background

Nort ⠀ 671

When I click on the button, my interface is blocked because the page is loading. How do I prevent my interface from blocking and loading in the background?

I tried to do this with streams and async methods.

I mainly used:
Activity.RunOnUiThread
A task

I couldn't solve it, but I know that the solution is near, you just need to choose the right path.

I need to implement for Android and iOS.

Your help is very important to me, because any answer can help me.

The way I see the result:

Pressing a button (navigate to another page)
Opening this page without blocking the interface
Loading information in the background
Automatic output of the loaded information to the page, without blocking the interface
Loading in real time or download indexer (ActivityIndicator), and then display the complete loaded information.

Did you place the long running tasks into async methods ?

Something like this

protected override void OnAppearing() { base.OnAppearing(); ActivityIndicator.IsRunning = true; //long task ActivityIndicator.IsRunning = false; }

In this way the interface would not be blocked .

For me it don't help =(
I think, my issue in ItemsSource="{Binding BigDataFromApi}).
When I open the page with a big ItemsSource, I have to wait close to 10 seconds.
