用藥提醒程序設計（原創）（定時、定時3次、按用戶定時，前半小時2分鍾提醒一次，後一個半小時10分鍾提醒一次）
思路大致是這樣的：
1.用戶手動輸入（模擬服務器發來的消息），將用藥提醒時間存入SQLITE數據庫，同時，每隔2分鍾的間隔錄入一個時間點，持續錄入15個（即30分鍾），每隔10分鍾的間隔錄入一個時間點，持續錄入9個（即90分鍾），共計2小時，24個標記位狀態都列為0；
2.如果到了時間點，響起鬧鈴，用戶取消，所有的標誌位都重新置為1；
3.如果到了SQLITE錄入時間點3小時以後的時間，所有的標誌位重新置為0；
4.監聽進程一直獲取當前的時間，如果當前的時間到了數據庫記錄的時間點，並且標誌位是0，則會響起鬧鈴。
將來的擴展：
1.數據庫要增加用戶字段，因為一個報警設備有多個用戶，並且每個用戶最多可以設置三個時間點，入庫過程之中是這樣的存儲結構。
id time user
0 13:43 zzk
1 13;45 tom
2 20:00 tom
3 21:00 tom
2.時間點存儲如下所示，根據不同的用戶，分別新建不一樣的文件：
<?xml version='1.0' encoding='utf-8' standalone='yes' ?> <map> <string name="10:01">1</string> <string name="10:03">1</string> <string name="10:23">1</string> <string name="09:53">1</string> <string name="09:51">1</string> <string name="10:13">1</string> <string name="09:41">1</string> <string name="11:13">1</string> <string name="11:23">1</string> <string name="11:33">1</string> <string name="10:53">1</string> <string name="11:03">1</string> <string name="10:33">1</string> <string name="10:43">1</string> <string name="09:39">1</string> <string name="09:37">1</string> <string name="09:35">1</string> <string name="09:33">1</string> <string name="09:43">1</string> <string name="09:57">1</string> <string name="09:45">1</string> <string name="09:55">1</string> <string name="09:47">1</string> <string name="09:49">1</string> <string name="09:59">1</string> </map>
