Try using Dialog dialog = new Dialog(MainActivity.this); instead of Dialog dialog = new Dialog(context); — Rehan

you should pass Activity reference to Dialog. see here stackoverflow.com/questions/20779377/… — Gopal Gopi

Suppose you are passing context from your Activity ActivityABC to your Adapter. Then create following variable in your adapter

Activity mActivity = null;

and pass context like this ActivityABC.this to variable mActivity in our adapter and then display dialog using:

Dialog dialog = new Dialog(mActivity);

Hope this trick works for you

actually just specifying getActivity() worked fine
