Question

我尝试将date设置为datepicker，它会显示错误...

我使用意图发送日期，它将在下一页设置... 那是我的问题...

我的代码是

声明datepicker对象，

 RewriteCond %{REQUEST_URI} !(.*)/$
 RewriteRule ^(.*)$ http://www.example.com/$1/ [L,R=301]

并在创建fn，

DatePicker datePicker;
String mydate="2016-12-07";

我尝试使用updateDate fn设置日期，

datePicker = (DatePicker) findViewById(R.id.schedule_datePicker);
String[] dateParts = mydate.split("-");

请帮助我如何解决这个问题..

Answer 1

考虑以下几点。

updateDate需要整数参数。
由于您使用预填充字符串作为日期，为什么不考虑将该方法添加为datePicker.updateDate(2016, 12, 7);？

试试这段代码，我希望能帮到你..

     final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                                  int dayOfMonth) {
                // TODO Auto-generated method stub

                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                updateLabel();
                //pick_date.setText(year+"-"+monthOfYear+1+"-"+dayOfMonth);
               // pick_date1 = year+"-"+monthOfYear+1+"-"+dayOfMonth;
            }
        };

 Calendar mcurrentTime = Calendar.getInstance();
                int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
                int minute = mcurrentTime.get(Calendar.MINUTE);
                TimePickerDialog mTimePicker;
                mTimePicker = new TimePickerDialog(BookNow.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                        String pick_times=selectedHour+":"+selectedMinute;
                        String converted_time=LibraryHelper.ChangeDateFormat(pick_times,"HH:mm","hh:mm a");
                        pick_time.setText( converted_time);
                    }
                }, hour, minute, false);//Yes 24 hour time
                mTimePicker.setTitle("Select Time");
                mTimePicker.show();

private void updateLabel() {

    String myFormat = "yyyy-MM-dd"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
}

是的，我试过这种方式来获得ans，

datePicker.updateDate(Integer.parseInt(dateParts[0]), Integer.parseInt(dateParts[1]), Integer.parseInt(dateParts[2]));

DatePicker中的更新日期无法应用于显示的android错误
