In Android how to pass ListAdapter values to onItemClick?

I've got a functioning search interface on my app. Now I'm trying to make each search result list item clickable and display in a new activity. I've got them clickable, but I can't figure out how to pass the ListAdapter values (records) into the onItemClick method.

Here's my code so far:

private void showResults(String query) {
    Cursor cursor = DBHelper.searchDB(query);
    startManagingCursor(cursor);
    String[] searchFrom = new String[] { DBAdapter.KEY_MAKE,
            DBAdapter.KEY_YEAR, DBAdapter.KEY_MAKE,
            DBAdapter.KEY_MODEL };
    int[] displayHere = new int[] { R.id.rDateTV, R.id.rYearTV,
            R.id.rMakeTV, R.id.rModelTV };

    final SimpleCursorAdapter records = new SimpleCursorAdapter(this,
            R.layout.record_2, cursor, searchFrom, displayHere);

    setListAdapter(records);
    DBHelper.close();

    // --- Click on list item ---


    ListView clickList = getListView(); 
    clickList.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
        @Override 
        public void onItemClick(AdapterView<?> parent, View view, int position, long id)        {
            //--- here's the problem: how do I pass the ListAdapter values into onItemClick. the below doesn't like .getText()
            String sYear = (view.findViewById(R.id.rYearTV)).getText().toString();
            String sMake = (view.findViewById(R.id.rMakeTV)).getText().toString();
            String sModel = (view.findViewById(R.id.rModelTV)).getText().toString();

            // -- then pass these strings to an intent to launch a new activity




        } 
    });


    // --- END click on list item ----

}

Any ideas? I'm a rookie here, so if you could show me the code, that would be AWSOME!

In OnItemClickListener.onItemClick call parent.getItemAtPosition(position). That method returns cursor which is set to the given position. Then get your data from that cursor. Don't close cursor inside OnItemClickListener.onItemClick.

for example:

ListView clickList = getListView(); 
    clickList.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
        @Override 
        public void onItemClick(AdapterView<?> parent, View view, int position, long id)        {
            Cursor c = (Cursor)parent.getItemAtPosition(position)
            String sMake = c.getString(c.getColumnIndexOrThrow(DBAdapter.KEY_MAKE));//get data from cursor

           ...
        } 
    });
