How to make ProgressBar progress in alertDialog?(Xamarin.Android) - xamarin.android

Question

I have the following code in alertDialog.SetPositiveButton
alertConfirmTransfer.SetPositiveButton("ДА", delegate
{
ProgressBar progressBar = FindViewById<ProgressBar>(Resource.Id.progressBar);
alertConfirmTransfer.Cancel();
MobileSellReference.Service1 service = new
MobileSellReference.Service1();
progressBar.IncrementProgressBy(10);
service.Url = settings.Synchronization.Msellurl;
progressBar.IncrementProgressBy(10);
byte[][] resultFromService = service.ToPPC(basedataZipName, objectId);
progressBar.IncrementProgressBy(10);
byte[] basedataZipFile = resultFromService[0];
byte[] dutybasedataZipFile = resultFromService[3];
byte[] tranbasedataZipFile = resultFromService[2];
byte[] vendbasedataZipFile = resultFromService[1];
progressBar.IncrementProgressBy(10);
string basedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + basedataZipName;
string dutybasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + dutybasedataZipName;
string tranbasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + tranbasedataZipName;
string vendbasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + vendbasedataZipName;
Helper.DeleteAllFromFolders(GlobalVariables.fromserverFolderPath, GlobalVariables.vendingFolderPath, GlobalVariables.tranFolderPath, GlobalVariables.debtFolderPath);
progressBar.IncrementProgressBy(10);
Helper.EmptyMobileSellDB();
progressBar.IncrementProgressBy(10);
System.IO.File.WriteAllBytes(basedataZipFullPath, basedataZipFile);
progressBar.IncrementProgressBy(10);
System.IO.File.WriteAllBytes(dutybasedataZipFullPath, dutybasedataZipFile);
progressBar.IncrementProgressBy(10);
System.IO.File.WriteAllBytes(tranbasedataZipFullPath, tranbasedataZipFile);
progressBar.IncrementProgressBy(10);
System.IO.File.WriteAllBytes(vendbasedataZipFullPath, vendbasedataZipFile);
progressBar.IncrementProgressBy(10);
}
I want the progress bar to increment in the places I specified . But when I run the app I have only progress bar circulating infinetly. I want to increase by and by. And After reaching 100 to dissapear. I've found too little information how to do that in Xamarin.Android and none of it helped me.

Answer 1

After the line where you findviewbyreference :
ProgressBar progressBar = FindViewById<ProgressBar>(Resource.Id.progressBar);
Set the max progress to 100 and then set the current progress to 0.
progressBar.Max = 100;
progressBar.Progress = 0;
Then incrementing the progress should work.
progressBar.IncrementProgressBy(10);
// Try adding delay after/before you set the progress.
// You can put the below code in a method and call that method after updating the progress bar.
try
{
Thread.Sleep(2000);
}
catch (Exception exception)
{
Android.Util.Log.Error("Error",exception.Message);
}

cs file
MobileSellReference.Service1 service = new MobileSellReference.Service1();
service.Url = settings.Synchronization.Msellurl;
progressBar.IncrementProgressBy(10);
Thread.Sleep(2000);
byte[][] resultFromService = service.ToPPC(basedataZipName, objectId);
progressBar.IncrementProgressBy(50);
Thread.Sleep(2000);
byte[] basedataZipFile = resultFromService[0];
byte[] dutybasedataZipFile = resultFromService[3];
byte[] tranbasedataZipFile = resultFromService[2];
byte[] vendbasedataZipFile = resultFromService[1];
string basedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + basedataZipName;
string dutybasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + dutybasedataZipName;
string tranbasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + tranbasedataZipName;
string vendbasedataZipFullPath = GlobalVariables.fromserverFolderPath + "/" + vendbasedataZipName;
Helper.DeleteAllFromFolders(GlobalVariables.fromserverFolderPath, GlobalVariables.vendingFolderPath, GlobalVariables.tranFolderPath, GlobalVariables.debtFolderPath);
progressBar.IncrementProgressBy(5);
Thread.Sleep(2000);
Helper.EmptyMobileSellDB();
progressBar.IncrementProgressBy(5);
Thread.Sleep(2000);
System.IO.File.WriteAllBytes(basedataZipFullPath, basedataZipFile);
progressBar.IncrementProgressBy(10);
Thread.Sleep(2000);
System.IO.File.WriteAllBytes(dutybasedataZipFullPath, dutybasedataZipFile);
progressBar.IncrementProgressBy(10);
Thread.Sleep(2000);
System.IO.File.WriteAllBytes(tranbasedataZipFullPath, tranbasedataZipFile);
progressBar.IncrementProgressBy(10);
Thread.Sleep(2000);
System.IO.File.WriteAllBytes(vendbasedataZipFullPath, vendbasedataZipFile);
The code above is in alert.SetPositiveButton("Yes" ....) method
