如何从日期选择器对话框中获取值

Question

如何获取我们在日期选择器对话框中按下的值

public void showDateTimePicker4(){
    final Calendar currentdate = Calendar.getInstance();
    date = Calendar.getInstance();

    DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker datePicker, int year, int month, int day) {
            year = datePicker.getYear();
            month = datePicker.getMonth();
            day = datePicker.getDayOfMonth();
            date.set(year, month, day);
        }
    };
    DatePickerDialog datePickerDialog = new DatePickerDialog(this, dateSetListener, date.get(Calendar.YEAR), date.get(Calendar.MONTH), date.get(Calendar.DAY_OF_MONTH));
    datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() -1000);
    datePickerDialog.show();
}

这是我的语法

jadwal4.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            showDateTimePicker4();
            currentDateString4 = date.getTime().toString();
            jadwalpilih4.setText(currentDateString4);



        }
    });

无法获取自定义值，只能获取当前时间值

请使用这个

  public void selectDate(View view) {
        final Calendar myCalendar = Calendar.getInstance();
        DatePickerDialog mDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, month);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

                SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT_ENGLISH, Locale.US);
              String mDate = sdf.format(myCalendar.getTime());
               jadwalpilih4.setText(mDate);


            }
        }, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));
        mDatePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        mDatePickerDialog.show();
    }

这条路

String selectedDate = ""; // decleare it in global scope
public void showDateTimePicker4(){
    final Calendar currentdate = Calendar.getInstance();
    date = Calendar.getInstance();

    DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener() {
        @Override
        public void onDateSet(DatePicker datePicker, int year, int month, int day) {
            selectedDate = new StringBuilder().append(month + 1)
               .append("-").append(day).append("-").append(year)
               .append(" ");

            // set selected date into textview
            jadwalpilih4.setText(selectedDate);
        }
    };
    DatePickerDialog datePickerDialog = new DatePickerDialog(this, dateSetListener, date.get(Calendar.YEAR), date.get(Calendar.MONTH), date.get(Calendar.DAY_OF_MONTH));
    datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() -1000);
    datePickerDialog.show();
}
