How would I add an onClickListener to this?

I have a database that I am displaying through a listview type thing, How would I add on OnClickListener?
Here's the code:

public void DisplayRecord(Cursor c) {
    Cursor c1 = DBAdapter.getAllRecords();
    startManagingCursor(c1);

    String[] from = new String[] { DBAdapter.KEY_ITEM };
    int[] to = new int[] { R.id.text1 };

    SimpleCursorAdapter notes = new SimpleCursorAdapter(this, R.layout.row,
            c1, from, to);
    setListAdapter(notes);
}

Or is it even possible?

And how would I sort this list alphabetically?

You want to use an OnItemClickListener with a ListView, or since you are using a ListActivity or ListFragment you can override OnListItemClick.

@Override
public void onListItemClick(ListView l, View v, int position, long id) {
    // Do something
}

And how would I sort this list alphabetically?

Use the Order By clause when you query your database in DBAdapter.getAllRecords();

You need to add a onItemClickListener to the listview. 

yourListVeiw.setOnItemClickListener(new AdapterView.OnItemClickListener() {
     public void onItemClick(AdapterView<?> parent, View view,
            int position, long id) {
 // id is the clicked item id
     Cursor clickedItem = DBAdapter.getRecord(id);
     // DO what you need to do

}

In order to have the list ordered you should implement a getSortedRecords() in your DBAdapter, adding an order by clause.

You certainly can, but you should set your listener on your ListView, not the adapter that provides its data.
Take a look at setOnItemClickListener on Android
