本文所講的內容是在Android系統中如何寫程序進行電話攔截,並發出攔截提示音提醒用戶,可以說此功能還是比較實用的。
1、電話攔截
這個功能大家可能都知道了,就是利用反射原理調用ITelephony的隱藏方法來實現。
2、攔截後提示忙音/空號/已關機/已停機
這個功能其實是要用到MMI指令,具體如何設置呼叫轉移的指定可以參考這裡 http://baike.baidu.com/view/206402.html?fromTaglist。
在本文中我們會用到“遇忙轉移”的功能。中國移動的設置方式是 **67#電話號碼#,取消方式為 ##67#。”無條件轉移“用21代替67即可。這兩個指令可以直接在手機的撥號界面輸入並撥號測試。ITelephony的endcall方法掛斷電話後,會提示電話忙。如果事前設置好了忙時轉移到一個空號/已關機/已停機的電話號碼,就會提示您撥的電話號碼是空號/已關機/已停機。
其實大家可以下載 xxx衛士看下,它設置來電拒接模式後,都是會啟動設置MMI指令的界面。然後再去“設置->通話設置->來電轉接”,看看 “占線時轉接” 設置好的電話號碼,就可以知道空號/已關機/已停機對應的電話號碼是什麼了。
1、修改一下BLOCKED_NUMBER這個變量值,把它設置為你要測試攔截的電話號碼。
2、全部功能是在一個Activity裡實現的,所以大家要先運行這個Activity,然後點擊“設置呼叫轉移”,設置好呼叫轉移後,不要關閉這個Activity,關了就攔截不了電話了。有心的朋友可以自己去寫一個Service在後台運行攔截功能。
