            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(getContext());
            alertDialogBuilder.setTitle("Title");
            alertDialogBuilder.setMessage("Message");
            alertDialogBuilder.setCancelable(true);
            alertDialogBuilder.setPositiveButton("yes", (dialog, id) ->
                    {

                    }
            );
            alertDialogBuilder.setNegativeButton("no", (dialog, id) -> dialog.cancel());
