You have to instantiate the inflater. Try to fit this line at the beginning of the method getView():

inflater = activity.getLayoutInflater();

You will need to find a replacement for the variable activity that effectively brings Activity, perhaps passing as an argument in your adapter’s constructor. Unfortunately I do not remember how to do it right on Android. Good luck.
