最近寫了個鬧鐘的程序，看到SharedPreferences在一個程序中可以共享數(shù)據(jù)，SharedPreferences是一個輕量級的鍵值存儲機制，只可以存儲基本數(shù)據(jù)類型。我就拿來用用，沒想到SharedPreferences太好了，真是輕量級的保存數(shù)據(jù)的好的工具，比sqlite好用多了！以后我又多了一種編程思想了，呵呵，所以現(xiàn)在分享給大家，特別注意這點：這個無法直接在多個程序間共享Preferences數(shù)據(jù)。程序關(guān)閉再打開時間仍然保留你上次設(shè)置的時間。這就是Preferences的作用！特別聲明：想要源碼的請在博客的留言版中留下郵箱。轉(zhuǎn)載請標(biāo)明出處： http://blog.csdn.net/wdaming1986/article/details/6705902

程序歡迎界面：點擊設(shè)置鬧鐘界面：

點擊鬧鐘設(shè)置中的設(shè)置后的界面：鬧鐘時間到了彈出dialog：

設(shè)置重復(fù)想起鬧鐘后的界面：點擊返回鍵彈出的提示：

下面請看代碼：
