如何在android中以"YYYY-MM-DD"格式获取Date对象

Date date = new Date();

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date date = sdf.parse(date.toString());

String dateString = sdf.format(date);

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Main {
    public static void main(String[] args) {
        Date date = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
        try {
            Date dateFormatted = sdf.parse(date.toString());
            String dateString = sdf.format(dateFormatted);
            System.out.println(dateString);
        } catch (ParseException e) {
            e.printStackTrace();
        }
    }
}
