Calendar cal = Calendar.getInstance();      
Calendar dt = Calendar.getInstance(); 
dt.clear();
dt.set(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH),cal.get(Calendar.DATE)); 
return dt.getTime();        

 String date = new SimpleDateFormat("yyyy-MM-dd").format(new Date());

//导入Date类为java.util

在当前地区(设备地区!)中获取当前日期的最简单方法:

String currentDate = DateFormat.getDateInstance().format(Calendar.getInstance().getTime());

如果你想拥有不同风格的日期，请使用getDateInstance(int style):

DateFormat.getDateInstance(DateFormat.FULL).format(Calendar.getInstance().getTime());

其他样式:DateFormat。长,DateFormat。DATE_FIELD DateFormat。DAY_OF_YEAR_FIELD等(使用CTRL+空格可以看到所有这些)

如果你也需要时间:

String currentDateTime = DateFormat.getDateTimeInstance(DateFormat.DEFAULT,DateFormat.LONG).format(Calendar.getInstance().getTime());

 public static String getcurrentDateAndTime(){

        Date c = Calendar.getInstance().getTime();
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");
        String formattedDate = simpleDateFormat.format(c);
        return formattedDate;
    }

// String currentdate=  getcurrentDateAndTime();

这是我使用的代码:

final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);

// Set current date into textview
tvDisplayDate.setText(new StringBuilder()
    .append(month + 1).append("-") // Month is 0 based, add 1
    .append(day).append("-")
    .append(year).append("   Today is :" + thursday ) );

// Set current date into datepicker
dpResult.init(year, month, day, null);

  public static String getDateTime() {
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MMMM dd, yyyy HH:mm:ss", Locale.getDefault());
        Date date = new Date();
        return simpleDateFormat.format(date);
    }
