给你个小例子，你可以去尝试一下哦，手动设置确定和取消按钮。
public void pickDate(View view) {
Calendar cal = Calendar.getInstance();
final DatePickerDialog mDialog = new DatePickerDialog(this, null,
cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH));
//手动设置按钮
mDialog.setButton(DialogInterface.BUTTON_POSITIVE, "完成", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
//通过mDialog.getDatePicker()获得dialog上的DatePicker组件，然后可以获取日期信息
DatePicker datePicker = mDialog.getDatePicker();
int year = datePicker.getYear();
int month = datePicker.getMonth();
int day = datePicker.getDayOfMonth();
System.out.println(year + "," + month + "," + day);
}
});
//取消按钮，如果不需要直接不设置即可
mDialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
System.out.println("BUTTON_NEGATIVE~~");
}
});
mDialog.show();
}
