            builder1.setPositiveButton(
                    "Yes",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, final int id) {

                            ref.child("recipe").addListenerForSingleValueEvent(new ValueEventListener() {
                                @Override
                                public void onDataChange(DataSnapshot dataSnapshot) {
                                    for(DataSnapshot uniqueKeySnapshot : dataSnapshot.getChildren()){
                                        String skey = uniqueKeySnapshot.getKey();
                                        uniqueKeySnapshot.child(String.valueOf(id)).child(skey).getRef().removeValue();                           //ref.child("recipe").child(skey).setValue(null);
                                    dialog.cancel();

                                    }
                                }
                                @Override
                                public void onCancelled(DatabaseError databaseError) {
                                    Toast.makeText(mContext, "error !"+databaseError.getMessage(), Toast.LENGTH_SHORT).show();
                                }
                            });



                            dialog.cancel();
                        }
                    });

            builder1.setNegativeButton(
                    "No",
                    new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                    });
