Adding rows to an ArrayAdapter is a pain. A better solution is found at: http://code.google.com/android/reference/android/widget/CursorAdapter.html which points out that a CursorAdapter (and thus a SimpleCursorAdapter) must be given a cursor with a column named "_id" or it will fail (specifically, it will produce the error: "java.lang.IllegalStateException Unable to get field slot").
I am an amature programmer who relies on people posting answers to discussion groups, and am thrilled that I *finally* figured something out so that I can make a contribution.
Have a good day! Dr. S

Well, I ended using a work arround.
I add each row of the cursor into an ArrayAdapter. I then use the the ArrayAdapter to populate the View(.setAdapter() ).
Hope that helps somone.

similar problem but with AutoCompleteTextView- so I
reduced it down to something along the lines of the list2 sample code by using some built in android.R view Ids, and I get the same exact error.
AutoCompleteTextView textView = (AutoCompleteTextView) findViewById(R.id.item_name); Cursor cur = dbHelper.getItemsListCursor(); SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_1, cur, new String[] {"name"} , new int[] {android.R.id.text1}); textView.setAdapter(adapter);
the cursor has a single column called "name". What are we doing wrong?

OK I think you need more details. I am just trying to set the Spinner (mRouteTypeSpin) with data from my local SQLite database (in the mCursor object).
//here are the variable definitions private Cursor mCursor;
//here is a snipit form the onCreate method: setContentView(R.layout.transit); Log.d(TAG,"INFLATE XML!!!"); mRouteTypeSpin = (Spinner) findViewById(R.id.routeTypeSpinner); ContentURI curi = ContentURI.create("content://time_table/ route_type"); mCursor = managedQuery(curi, new String[] {"route_type"}, null, null); //this returns a Cursor(mCursor) with one column and three rows in it SpinnerAdapter adapter = new SimpleCursorAdapter(this,android.R.layout.simple_spinner_item_big, mCursor, new String[] {"route_type"}, new int[] {android.R.id.text1});
mRouteTypeSpin.setAdapter(adapter); //this statement causes the IllegalStateException

Let me know if I can provide any information. Am I applying the results of my query to the Spinner widget correctly?- Hide quoted text -
