我在代码中使用 DatePickerDialog 。我想知道,如何以 dd mm yyyy 格式更改 DatePickerDialog 日历的日期格式。
我的代码是:-
public static class DatePickerDialogTheme5 extends DialogFragment implements DatePickerDialog.OnDateSetListener{
@Override
public Dialog onCreateDialog(Bundle savedInstanceState){
SimpleDateFormat sdf=new SimpleDateFormat("dd MM yyyy");
Date d=new Date();
sdf.format(d);
final Calendar calendar = Calendar.getInstance();
calendar.setTime(d);
calendar.set(calendar.YEAR,d.getYear());
calendar.set(calendar.MONTH,d.getMonth());
calendar.set(calendar.DAY_OF_MONTH,d.getDay());
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int day = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datepickerdialog = new DatePickerDialog(getActivity(),
//AlertDialog.THEME_TRADITIONAL,this,day,month,year);
AlertDialog.THEME_DEVICE_DEFAULT_DARK,this,year,month,day);
return datepickerdialog;
}
public void onDateSet(DatePicker view, int year, int month, int day){
TextView textview = (TextView)getActivity().findViewById(R.id.textView1);
textview.setText(day + ":" + (month+1) + ":" + year);
}
}
我想像这样显示日期选择器对话框 https://i.stack.imgur.com/1EU89.png
不确定你想实现什么,但你可以使用Calendar
实例与SimpleDateFormat
格式化你的Date
根据您的需要。
例如:
public void onDateSet(DatePicker view, int year, int month, int day) {
Calendar calendar = Calendar.getInstance();
calendar.set(year, month, day);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd:MM:yyyy");
String dateString = dateFormat.format(calendar.getTime());
TextView textview = (TextView)getActivity().findViewById(R.id.textView1);
textview.setText(dateString);
}
