I created an Android application with a Spinner and a TextView. I want to display the selected item from the Spinner's drop down list in the TextView. I implemented the Spinner in the onCreate method so when I'm running the program, it shows a value in the TextView before selecting an item from the drop down list.

This enables one set of methods in the superclass and supports multiple AdapterViews and therefor multiple spinners. I have 2 spinners and I update them during init and during interactions with other controls or after getting data from the server. When the class is initiating use setSpinnersListeners instead of directly setting the listener. The Runnable will prevent the spinner from firing onItemSelected right after the you set their values.

If you need to update the spinner after a server call etc. Android spinner onitemselected will prevent onItemSelected from firing after the update. Learn more. First 10 Free.
