SfBusyIndicator in a Fragment

[Vince]

Hello,

In my project I have five Fragment layouts and when the user chooses the last Fragment the SfBusyIndicator must be shown. I tried it with the next code in MainActivity.cs but the app crashes without an error and without showing the SfBusyIndicator:

private async void ShowBusyIndicator(Android.Views.View viewTabLayout4)

        {

            var busyIndicator = new SfBusyIndicator(viewTabLayout4.Context);

            busyIndicator.IsBusy = true;

            busyIndicator.ViewBoxHeight = 100;

            busyIndicator.ViewBoxWidth = 100;

            busyIndicator.AnimationType = AnimationTypes.SingleCircle;

            busyIndicator.Title = "Laden...";

            busyIndicator.TextSize = 50;

            var layout = viewTabLayout4.FindViewById<ScrollView>(Resource.Id.ScrollView4);

            layout.AddView(busyIndicator);

            await Task.Delay(5000);

            busyIndicator.IsBusy = false;

            busyIndicator.Visibility = Android.Views.ViewStates.Invisible;

        }

Do you have a sample implementing the SfBusyIndicator in Fragments?

Hi Vince,

We have checked your requirement "SfBusyIndicator in a Fragment" from our side and we have created a sample based on your requirement.

Please find the sample from the below link.

Sample: http://www.syncfusion.com/downloads/support/forum/135477/ze/BusyIndicatorSample-488383939

 

So, Could you please provide the modified sample which replicates the reported issue "App crashes without an error and without showing the SfBusyIndicator".

It will help us to provide appropriate solution on this.

Hi Vinnalan,

I found my error. After adding the code "layout.RemoveAllViews();" it worked because the View in my Fragment was occupied by another Syncfusion control.

So I changed my code in:

private async void ShowBusyIndicator(Android.Views.View viewTabLayout4)

        {

            var busyIndicator = new SfBusyIndicator(viewTabLayout4.Context);

            busyIndicator.IsBusy = true;

            busyIndicator.ViewBoxHeight = 100;

            busyIndicator.ViewBoxWidth = 100;

            busyIndicator.AnimationType = AnimationTypes.SingleCircle;

            busyIndicator.Title = "Laden...";

            busyIndicator.TextSize = 50;

            var layout = viewTabLayout4.FindViewById<ScrollView>(Resource.Id.ScrollView4);

            layout.RemoveAllViews();

            layout.AddView(busyIndicator);

            await Task.Delay(5000);

            busyIndicator.IsBusy = false;

            busyIndicator.Visibility = Android.Views.ViewStates.Invisible;

        }

Thanks for your support.
