Answer 1

尝试这样的希望工作

private void displayDate() {

    Calendar mCalendar = Calendar.getInstance();
    new DatePickerDialog(getActivity(), (OnDateSetListener) new OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
    int dayOfMonth) {
    // TODO Auto-generated method stub
       PickDate.append(monthOfYear + 1).append("-").append(
           .append("-").append(year));

    }
    }, mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH),
    mCalendar.get(Calendar.DATE));
    }

Answer 2

在您的按钮中，点击这样的DateFragment

yourButton.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {

        DialogFragment newFragment = new DateFragment();
        newFragment.show(getFragmentManager(), "DatePicker");

    }
});

for DateFragment

public class DateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
    final Calendar calendar = Calendar.getInstance();
    int yy = calendar.get(Calendar.YEAR);
    int mm = calendar.get(Calendar.MONTH);
    int dd = calendar.get(Calendar.DAY_OF_MONTH);
    return new DatePickerDialog(getActivity(), this, yy, mm, dd);
    }

    public void onDateSet(DatePicker view, int yy, int mm, int dd) {
        populateSetDate(yy, mm+1, dd);
    }
    public void populateSetDate(int year, int month, int day) {
        dob.setText(month+"/"+day+"/"+year);
        }

}
