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();

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());

您可以使用以下代码获得所需格式的日期。

String date = String.valueOf(android.text.format.DateFormat.format("dd-MM-yyyy", new java.util.Date()));

In Kotlin you can use this code : - 

Simple only need to change date format to this "dd-MM-yyyy" 
val d = Date()
val str: CharSequence = DateFormat.format("dd-MM-yyyy", d.getTime())
Log.e("", str.toString())
    
In Java You use this code: - 
    
Date date = new Date();
CharSequence str  = DateFormat.format("dd-MM-yyyy", date.getTime());
Log.e("Date", str.toString())

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

Calendar c = Calendar.getInstance();
int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + (month + 1) + "/" + year;

Log.i("TAG", "--->" + date);
