                  LayoutInflater inflater =getLayoutInflater();
                  View layout = inflater.inflate(R.layout.alert_dialog_content, null);
                  AlertDialog musicDialog = new AlertDialog.Builder(this, AlertDialog.THEME_HOLO_LIGHT).create();
                  musicDialog.setView(layout);
                  TextView textView = (TextView)layout.findViewById(R.id.message);
                  textView.setText(mDialogDesc);
                  musicDialog.setTitle(R.string.delete_item);
                  musicDialog.setButton(DialogInterface.BUTTON_POSITIVE, getResources().getString(R.string.delete_confirm_button_text), mButtonClicked);
                  musicDialog.setButton(DialogInterface.BUTTON_NEUTRAL, getResources().getString(R.string.cancel), mButtonClicked);
                  musicDialog.setCanceledOnTouchOutside(true);
                  musicDialog.setCancelable(true);
                  musicDialog.setOnKeyListener(mSearchKeyListener);
                  musicDialog.setIcon(android.R.drawable.ic_dialog_alert);
                  return musicDialog;
