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
