mDialog = new Dialog(this, R.style.chooseUserDialogTheme);
mDialog.setTitle(R.string.choose_user);
View rootView = LayoutInflater.from(this).inflate(
    R.layout.view_simple_choose_user, null);
mDialog.setContentView(rootView);
mLinearLayoutUserList = (LinearLayout) rootView
    .findViewById(R.id.linearLayout_user_list);
mDialog.show();
mIsUserListShown = true;
DialogInterface.OnDismissListener listener = new DialogInterface.OnDismissListener() {
  @Override
  public void onDismiss(DialogInterface dialog) {
    timer.cancel();
    mIsUserListShown = false;
