android DatePickerDialog 只显示一个按钮

Question

我知道 DatePickerDialog 有很多问题，如这篇文章所述 Jelly Bean DatePickerDialog --- is there a way to cancel?但我的问题是我想只显示确认按钮而不是两个按钮。我在 DialogFragment 中使用 DatePickerDialog，如下所示:

public class DateDialog extends DialogFragment implements DatePickerDialog.OnDateSetListener {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the picker
    final Calendar c = Calendar.getInstance();
    int year = c.get(Calendar.YEAR);
    int month = c.get(Calendar.MONTH);
    int day = c.get(Calendar.DAY_OF_MONTH);

    // set up mindate
    minYear = year;
    minMonth = month;
    minDay = day;

    // Create a new custom instance of DatePickerDialog and return it
    return new CustomDatePickerDialog(getActivity(), this, year, month, day);
}
}

我终于找到了一个更简单的解决方案。这是我的 CustomDatePickerDialog 中的工作区，它扩展了 DatePickerDialog

public CustomDatePickerDialog(Context context, OnDateSetListener callBack, int year, int monthOfYear,int dayOfMonth) {
    super(context, callBack, year, monthOfYear, dayOfMonth);
    this.setButton(DatePickerDialog.BUTTON_POSITIVE, "OK",this);
    this.setButton(DatePickerDialog.BUTTON_NEGATIVE, "",this);  // hide cancel button

}
