Android日期格式和字符串格式相互转换

1  Date转成String

/*** 日期转换成字符串* @param date* @return str*/public static String DateToStr(Date date) {SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");String str = format.format(date);return str;}

2 String转成Data

public static Date StrToDate(String str) {SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");Date date = null;try {date = format.parse(str);} catch (ParseException e) {e.printStackTrace();}return date;}
