Retrieve data from parse.com and populate a textfield

This is doing my head in. I got this working in iOS in about 10 mins. Clearly I'm missing something. I'm simply trying to pull data out of parse.com into a textfield. I have found lots of examples but none explaining why it's not working correctly. Below is the code pulled from parse.com site and jiggyed with. Incidentally it's wigging out on totemList.getString particularly the "getString" part.

 ParseQuery<ParseObject> query = ParseQuery.getQuery("Birds");
           query.whereEqualTo("totemName", "Pigeon");
           query.findInBackground(new FindCallback<ParseObject>() {
               public void done(List<ParseObject> totemList, ParseException e) {
                   if (e == null) {
                       Log.d("score", "Retrieved " + totemList.size() + " scores");
                       String totemDesc = totemList.getString("totemDesc");
                       //Get the Totems Description
                       TotemDescription = (TextView)findViewById(R.id.animalDesc);
                       TotemDescription.setText(totemDesc);
                   } else {
                       Log.d("score", "Error: " + e.getMessage());
                       // something went wrong
                       TotemDescription = (TextView)findViewById(R.id.animalDesc);
                       TotemDescription.setText("not bob");
                   }
               }
           });

List<> does not have a getString() method.

List<ParseObject> totemList

Perhaps what you wanted to do was to iterate over your list of ParseObject get all the descriptions:

String descriptions = null;
for (ParseObject totem : totemList) {
    if (descriptions == null) {
        descriptions = totem.getString("totemDesc");
    } else {
        descriptions = descriptions + ", " + totem.getString("totemDesc");
    }
}

Something like that. Then set the resulting string as text of your text field

TotemDescription.setText(descriptions);

If you have more than one ParseObject in your List<> your text will be something like: 

Pigeon Totem, Another Pigeon Totem
