    I’m trying to get a text box that looks like a spinner to activate a date picker dialog. This is done in both the Google Calendar app and the Contacts app (for birthdate) on ICS. Do I need to use a spinner, and if so how do I change it’s input view to be a date picker? Or if not, how do I get a text view to have the little triangle that usually indicates a spinner?

    I’m creating an Android app that takes in basic user input (from keyboard) via an EditText widget. I’m getting some stubborn behavior from a line I call within the OnItemSelected function for my Activity’s Spinners. I am gathering the double value from my EditText (doing appropriate type conversions), and the app crashes. My logcat’s report that the error is that “” is not an appropriate double value, which means that this function is being called while the EditText is still empty (I’m guessing

I’m trying to create a very basic program with a Spinner box that gives output on the selection Ive made via an TextView or System.Out.printIn.
