【问题描述】：

在这里我为日期选择器制作了一个简单的代码，它适用于当前日期、年份和日期，它不适用于片段

   public class Activity extends Sherlockfragment {

    EditText  dob;
    public static final int DATE_DIALOG_ID = 1009;
    String dob_string;
    int year = 2013, month = 10, day = 1, dayofmonth = 1;

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
view = inflater.inflate(R.layout.update_profile, container, false);

            mdob = (EditText)view. findViewById(R.id.dob);
          mdob.setOnClickListener(new View.OnClickListener() {

        @SuppressWarnings("deprecation")
        public void onClick(View v) {
            // TODO Auto-generated method stub
            showDialog(DATE_DIALOG_ID);
        }});
return view;
}

// ****************************#DATE PICKER DIALOG# **************************
@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        // set date picker as current date
        return new DatePickerDialog(this, datePickerListener, year, month,
                day);
    }
    return null;
}

 private DatePickerDialog.OnDateSetListener datePickerListener = new   DatePickerDialog.OnDateSetListener() {
    // when dialog box is closed, below method will be called.
    public void onDateSet(DatePicker view, int selectedYear,
            int selectedMonth, int selectedDay) {
        year = selectedYear;
        month = selectedMonth + 1;
        day = selectedDay;
        Calendar cal = Calendar.getInstance();
        cal.set(selectedYear, selectedMonth, selectedDay);
        DateFormatSymbols dfs = new DateFormatSymbols(Locale.getDefault());
        String weekdays[] = dfs.getWeekdays();
        int daykk = cal.get(Calendar.DAY_OF_WEEK);
        String dayof = weekdays[daykk];
        mdob.setText(day + "-" + month + "-" + year + dayof);
        mdob_string = day + "-" + month + "-" + year;
    }};
    }

【问题讨论】：

到底发生了什么？你到底想要什么？
你有问题要问吗？
不工作意味着什么..
public final boolean showDialog (int id, Bundle args) 在 API 级别 8 中添加此方法在 API 级别 13 中已弃用。将新的 DialogFragment 类与 FragmentManager 一起使用；这也可以通过 Android 兼容性包在旧平台上使用。
@PiyushGupta 它不工作所以你能提供我任何参考

public class Activity extends Sherlockfragment {

    static EditText  mdob;

    static String dob_string;


@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
view = inflater.inflate(R.layout.update_profile, container, false);

            mdob = (EditText)view. findViewById(R.id.dob);
          mdob.setOnClickListener(new View.OnClickListener() {

        @SuppressWarnings("deprecation")
        public void onClick(View v) {
            // TODO Auto-generated method stub
DialogFragment newFragment = new DatePickerFragment();

                        newFragment.show(getActivity().getSupportFragmentManager(), "datePicker");

        }});
return view;
}
    // *********************************CLASS****************************************************************************



public static class DatePickerFragment extends DialogFragment implements
            DatePickerDialog.OnDateSetListener {

        int year = 2013, month = 10, day = 1, dayofmonth = 1;


        public Dialog onCreateDialog(Bundle savedInstanceState) {
            // Use the current date as the default date in the picker

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

        public void onDateSet(DatePicker view, int selectedYear,
                int selectedMonth, int selectedDay) {
            // Do something with the date chosen by the user

            year = selectedYear;
            month = selectedMonth + 1;
            day = selectedDay;
            Calendar cal = Calendar.getInstance();
            cal.set(selectedYear, selectedMonth, selectedDay);
            DateFormatSymbols dfs = new DateFormatSymbols(Locale.getDefault());
            String weekdays[] = dfs.getWeekdays();
            int daykk = cal.get(Calendar.DAY_OF_WEEK);
            String dayof = weekdays[daykk];

 Activity.mdob.setText(day + "-" + month + "-" +        year + dayof);
 Activity.mdob_string = day + "-" + month + "-" + year;

        }
    }

    }

它工作正常......

【解决方案2】：

您可以为此创建一个自定义类，如下所示：

public static class DatePickerFragment 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);

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

    public void onDateSet(DatePicker view, int year, int month, int day) {
        // Do something with the date chosen by the user
    }
}
