Question

我试图在用户点击edittext时在我的片段中显示一个DatePickerDialog

//initialise
Calendar newCalendar = Calendar.getInstance();
    datePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int month, int day) {

            etDate.setText(day + "/" + month + "/" + year);
        }

    },newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));

//show on click
datePickerDialog.show();

问题是最终：

我试图将DatePickerDialog设为一个单独的类，但它显示的是类似/相同的错误。

初始化应该触发datepicker的edittext：

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.host_activity, container, false);

    View footer = inflater.inflate(R.layout.footer_host, container, false);


    init(view, footer);




    return view;
}


private void init(View view, View footer) {
    etDate = (EditText) footer.findViewById(R.id.etDate);
    etDate.setOnClickListener(this);
    ....
}

我建议您使用第三方库。因为在本地日期选择器中，您在某些API中遇到了一些错误。

  compile 'com.wdullaer:materialdatetimepicker:2.4.0'

你可以像下面这样使用它：

    Calendar cal = Calendar.getInstance();
            int  byear = cal.get(Calendar.YEAR);
            int bmonth = cal.get(Calendar.MONTH);
            int bday = cal.get(Calendar.DAY_OF_MONTH);

            com.wdullaer.materialdatetimepicker.date.DatePickerDialog dialog= com.wdullaer.materialdatetimepicker.date.DatePickerDialog.newInstance(new com.wdullaer.materialdatetimepicker.date.DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(com.wdullaer.materialdatetimepicker.date.DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
                    etDob.setText(new StringBuilder().append(dayOfMonth)
                            .append("/").append(monthOfYear + 1).append("/").append(year));
                    if (etDob.getText().toString().length() == 0) {
                        etDob.setError("select Date");

                    } else {
                        etDob.setError(null);

                    }
                }
            }, byear, bmonth, bday);
            dialog.setMaxDate(cal);
            dialog.show(getActivity().getFragmentManager(),"DatePicker");

如果您不想使用第三方库。然后你可以实现如下。：

    private void setOnDateSet() {
    date = new DatePickerFragment();
    ondate = new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int myear, int monthOfYear,
                              int dayOfMonth) {


            etDob.setText(new StringBuilder().append(dayOfMonth)
                    .append("/").append(monthOfYear + 1).append("/").append(myear));
            if (etDob.getText().toString().length() == 0) {
                etDob.setError("select Date");

            } else {
                etDob.setError(null);

            }

        }

    };
}


public class DatePickerFragment extends android.app.DialogFragment {
    DatePickerDialog.OnDateSetListener ondateSet;
    int byear, bmonth, bday;


    public DatePickerFragment() {
    }

    public void setCallBack(DatePickerDialog.OnDateSetListener ondate) {
        ondateSet = ondate;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {


        Calendar cal = Calendar.getInstance();
        byear = cal.get(Calendar.YEAR);
        bmonth = cal.get(Calendar.MONTH);
        bday = cal.get(Calendar.DAY_OF_MONTH);


        DatePickerDialog _date = new DatePickerDialog(getActivity(), ondateSet, byear, bmonth, bday);
        _date.getDatePicker().setMaxDate(System.currentTimeMillis());
        return _date;
    }


}

你可以在edittext click listner上调用它：

       setOnDateSet(); // **** Set date on Button text
           date.setCallBack(ondate);
           date.show(getActivity().getFragmentManager(), "DatePicker");

公开定义：

  private DatePickerFragment date;


 private DatePickerDialog.OnDateSetListener ondate;

InflateException DatePicker
