Question

用户在UI上的EditText行输入日期。我将Bundle中的日期传递给DatePickerDialog片段。我希望DatePicker对话框显示用户的日期而非今天的日期，但今天的日期仍在继续显示。我在这里缺少什么？

活动文件：

...
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.cardviewinput);

    fListenerEditText = (ListenerEditText) findViewById(R.id.FEditText);

    fListenerEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {

        if (hasFocus && (fListenerEditText.getText().length() == 0)) {

              DatePickerFragment newFragment = new DatePickerFragment();
              newFragment.show(getSupportFragmentManager(), "datePicker");
           }
           else {
               Bundle bundle = new Bundle();
               Calendar c = Calendar.getInstance();
               bundle.putInt("year", c.get(Calendar.YEAR));
               bundle.putInt("month", c.get(Calendar.MONTH));
               bundle.putInt("day", c.get(Calendar.DAY_OF_MONTH));
               DatePickerFragment newFragment = new DatePickerFragment();
               newFragment.setArguments(bundle);
               newFragment.show(getSupportFragmentManager(), null);
           }
        }
    });

片段文件：

...
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

Calendar c;
int year = 0, month = 0, day = 0;

public DatePickerFragment() {
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    if (getArguments() != null) {
        c =  Calendar.getInstance();
        year = getArguments().getInt("year");
        month = getArguments().getInt("month");
        day = getArguments().getInt("day");
        c.set(year, month, day);
    }
    else {
        c = Calendar.getInstance();
        year = c.get(Calendar.YEAR);
        month = c.get(Calendar.MONTH);
        day = c.get(Calendar.DAY_OF_MONTH);
    }

    DatePickerDialog picker = new DatePickerDialog(getActivity(),
            this, year, month, day);
    picker.getDatePicker().setCalendarViewShown(true);
    picker.getDatePicker().setSpinnersShown(false);
    picker.setTitle("Select a Due Date");
    return picker;
}

public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
     EditText txtDate = (EditText) getActivity().getWindow().getDecorView().getRootView().findViewById(R.id.FEditText);
     txtDate.setText((monthOfYear + 1) + "/" + dayOfMonth + "/" + year + " ");
     txtDate.setSelection(txtDate.getText().length());
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current date as the default date in the picker
    final Calendar c = Calendar.getInstance();
    year_p = c.get(Calendar.YEAR);
     month_p = c.get(Calendar.MONTH);
     day_p = c.get(Calendar.DAY_OF_MONTH);

    // Create a new instance of DatePickerDialog and return it
    return new DatePickerDialog(getActivity(), this, year_p, month_p, day_p
            );
}
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
    Calendar c = Calendar.getInstance();
    c.set(year, month, day);

     if (year < year_p)
     {
       //  view.updateDate(year_p, month_p, day_p);
        custom_dialog(getActivity());
     }

     else if (month < month_p && year == year_p)
     {
       //  view.updateDate(year_p, month_p, day_p);
        custom_dialog(getActivity());
     }
     else  if (day < day_p && year == year_p && month == month_p)
     {
        // view.updateDate(year_p, month_p, day_p);
        custom_dialog(getActivity());

     }
     else   if(day<day_p && year<year_p && month<month_p)
     {
        custom_dialog(getActivity());

     }

     else if(day>=day_p && year>=year_p && month>=month_p)
     {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
    String formattedDate = sdf.format(c.getTime());
     if(CommonCode.isPastDate(formattedDate, "yyyy-MM-dd")==false)
     {
        // Toast.makeText(getActivity(), "passssst", Toast.LENGTH_SHORT).show();
    DialogFragment newFragment = new TimePickerFragment();
    newFragment.show(getFragmentManager(), "timePicker");
    str_setdate=formattedDate;
     }
     }
}

如何将Fragment的包参数传入DatePicker？
