If you read closely the getItemViewType method documentation, it says :

Integers must be in the range 0 to getViewTypeCount() - 1

In your case, in the range [0, 1]

Answer 2

You have-

if (info.getPhraseID() > 0)
  return 2;
else
  return 1;

Shouldn't it be-

if (info.getPhraseID() > 0)
  return 1;
else
  return 0;
