I'm a volunteer with very limited Java/Android Studio experience. This UpdateView.java has two "toggle" buttons. When one of these buttons is first pressed, a status and datetime is saved for that participant. If pressed again, the same button allows clearing of these values (in case a mistake was made). I would like to insert a Y/N confirmation but only before clearing the values. I read a lot of posts on AlertDialog and tried my best to implement this. However, when I press the button a second time to clear, I can see briefly the Yes/No dialog but it doesn't wait for keypress and performs the clear immediately. Any help would be greatly appreciated.

Those 3 lines need to go into the click listener of your yes/no dialog:
my_db = new DBHelper(context);
my_db.updateCoureurs(model.getDossard(), null);
showMessage("Temps de passage EFFACÉ pour ce coureur");
