C#, Android: Build own event listener

Question

here is the problem. I am using a custom component from someone else called a "Fancy showcase view". It focuses on buttons in my activity on highlights them with a text as a tutorial through the app. I am starting the first message, and when the user dissmises this by clicking anywhere in the activity, the next button is supposed to be highlighted. Unfortunately, the component, which otherwise is perfect, doesnt have a listener implemented like "OnDismis" of the first tutorial view so the next could start. Just putting both into code one after the other skips the second one. It also tried working with lifecycle methods, such as OnFocuseChanged() but even after the tutorial gets dismissed, this method isnt called a second time. What would you guys say is the best way to handle this? Here is what is NOT working:

            try
            {
                new FancyShowCaseView.Builder(this) // if this crashes, we need clean rebuild
                    .Title(title1)
                    .TitleStyle(0, (int)GravityFlags.Center | (int)GravityFlags.Center)
                    .Build()                      
                    .Show();
            }
            catch (Exception e)
            {
                Toast.MakeText(this, "There was an error ... " + e, ToastLength.Short).Show();
            }

            try
            {
                new FancyShowCaseView.Builder(this) // if this crashes, we need clean rebuild
                    .Title("TEST")
                    //.TitleStyle(0, (int)GravityFlags.Center | (int)GravityFlags.Center)
                    .FocusOn(txtL)
                    .Build()
                    .Show();
            }
            catch (Exception e)
            {
                Toast.MakeText(this, "There was an error ... " + e, ToastLength.Short).Show();
            }

The second one doesnt show up. There are no event handlers and I cannot make use of lifecycle methods. Click counting wouldnt work either, since the user might click on the activity while it is loading so hard coded values arent a good option either. Any ideas?

Thanks:)

Use the FancyShowCaseQueue to control the sequence.

You add individual FancyShowCaseViews to it and when you "Show()" the queue, each FancyShowCaseView happens in the order in-which you added them to the queue.

Example:

var fancyView1 = new FancyShowCaseView.Builder(this)
                  .Title("StackOverflow 1")
                  .FocusOn(button1)
                  .Build();
var fancyView2 = new FancyShowCaseView.Builder(this)
                  .Title("StackOverflow 2")
                  .FocusOn(button1)
                  .Build();

var fancyQueue = new FancyShowCaseQueue()
                      .Add(fancyView1)
                      .Add(fancyView2);
fancyQueue.Show();

I am using a Xamarin.Android binding library of FancyShowCaseView, but you can review the Java-based examples are in the sample app in the repo, ie:AnimatedActivity.java

Also you can implement the ME.Toptas.Fancyshowcase.IDismissListener interface:

public void OnDismiss(string p0)
{
    // 
}

public void OnSkipped(string p0)
{
    //
}

And use that implementation on each of your FancyShowCaseViews:

var fancyView2 = new FancyShowCaseView.Builder(this)
                        .Title("StackOverflow 2")
                        .FocusOn(button2)
                        .DismissListener(this)
                        .Build();
