title: Showing a loading screen during fragment switching
body: <p>I'm trying to show a loading screen (ACR.Dialogs) while showing a new fragment, tried the following code however, the loading popup doesnt show; i know that i should be using threading however this is a click event, `        </p>
  
  <pre><code>private void buttonloginClick(object sender, EventArgs e)
      {
          UserDialogs.Instance.ShowLoading("Wait Please");
          FragmentTransaction ft = FragmentManager.BeginTransaction();
          ActiveJobs activeJobs = new ActiveJobs();
          ft.Replace(Resource.Id.ll_frameLayout, activeJobs, "activeJobs");
          FragmentManager.PopBackStack();
          ft.AddToBackStack(null);
          ft.Commit();
      }`
  </code></pre>
