Android: Updating a ListView when the content of a SearchView is changed with results from Google Places API

Question

I am trying to update a ListView with Google Places API when the value of the SearchView is changed. There is a problem when the list view gets updated.

Here is my class, SearchFragment. https://gist.github.com/anonymous/d5fc885cca8426736888

onListItemClick gets the latitude and longitude of the item clicked by the user, and using a public interface of the fragment, it's passed to the activity.

The problem is that the ListView contains items that aren't in the list of predictions, even though I'm using the list of predictions that gets returned to update the ListView each time. If I click on something other than the first one, it will return the wrong coordinates, or the index will be out of range of the list of predictions, causing a null pointer exception on the first line of onListItemClick.

It doesn't seem like I'm going about this in the cleanest way. Could somebody please point in the right direction?

You should cancel the previous request when "onQueryTextChange" is called again.
