如果你只想获取日期，就像这样输入代码

Calendar.getInstance().getTime();

 public String giveDate() {
    Calendar cal = Calendar.getInstance();
    SimpleDateFormat sdf = new SimpleDateFormat("EEE, MMM d, yyyy");
    return sdf.format(cal.getTime());
 }

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);

CharSequence s  = DateFormat.getDateInstance().format("MMMM d, yyyy ");

首先需要一个实例

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();
