I m all new to Android and I m trying to create a spinner programmatically and feeding it with data from an array  but Eclipse gives me a warning that I can t handle   Here s what I got      This ArrayList holds the elements that should be in the spinner  gets   filled from a file later on        ArrayList lt String gt  spinnerArray   new ArrayList lt String gt       This is code I found on a site which should create the spinner   Spinner spinner   new Spinner this   ArrayAdapter spinnerArrayAdapter   new ArrayAdapter this                  android R layout simple spinner dropdown item                  spinnerArray   spinner setAdapter spinnerArrayAdapter     Now the second line  ArrayAdapter     gives me a warning in Eclipse saying  ArrayAdapter is a raw type    References to generic type ArrayAdapter lt T gt  should be parameterized   I have no idea how to fix this  or what that means in the first place        It s just a warning and the App seems to run alright  but I d still like to understand what s wrong and fix it  Any hint is appreciated   Greetings  Select0r
