I am using the following code to set the adapter (SimpleCursorAdapter) for an AutoCompleteTextView
mComment = (AutoCompleteTextView) findViewById(R.id.comment);
When I make a selection from the list I get a sqlite object ('android.database.sqlite.SQLiteCursor@'... ) in the textview.
You do not say what this "textview" is or how it relates to the Spinner.
I am going to take an educated guess and assume that you are simply assigning the selected item out of the Spinner into the TextView.
The selected item from a Spinner using a SimpleCursorAdapter is a Cursor, pointing at the row the user selected. The toString() implementation of Cursor will give you something akin to android.database.sqlite.SQLiteCursor@ depending on where the Cursor came from.
More likely, you are going to want to call getString() on that Cursor, to retrieve some column value, and assign it to the TextView in question.
