For starting an activity from baseadpater you have to do like this :

 Intent callIntent = new Intent(Intent.ACTION_CALL);  
                    callIntent.setData(Uri.parse("tel:"+number));  
                            in.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

                            context.startActivity(callIntent );
