可變時(shí)間格式："yyyy-MM-dd HH:mm:ss"

保存鬧鐘時(shí)間：

• SimpleDateFormat df = new SimpleDateFormat("HH:mm");//設(shè)置日期格式

• String thistime = df.format(new Date());

• SharedPreferences sharedPreferences = getSharedPreferences("industryInfo", Context.MODE_PRIVATE); //私有數(shù)據(jù)

• SharedPreferences.Editor editor = sharedPreferences.edit();//獲取編輯器

• editor.putString(“retime”, thistime);//名稱 id

• editor.commit();//提交
