Update ListView in the main thread from another thread

Question

I have a separate thread running to get data from the internet. After that, I would like to update the ListView in the main thread by calling adapter.notifyDataSetChanged().

Answer 1

Use AsyncTask ( http://developer.android.com/reference/android/os/AsyncTask.html ).

Invoke adapter.notifyDataSetChanged() in onPostExecute(...) method.
