android 如何判断去电或来电已经接通

1、在CallNotifier.java (packages\apps\Phone\src\com\android\phone)中定义一个成员变量private Call.State mLastCallState = Call.State.IDLE;

2、在函数onPhoneStateChanged的开始添加代码

Call.State ringCallState = mCM.getFirstActiveRingingCall().getState();

Call.State fgCallState = mCM.getActiveFgCallState();

if ((mLastCallState.isRinging() && ringCallState == Call.State.IDLE) || //MT

(mLastCallState.isDialing() && fgCallState == Call.State.ACTIVE)) //MO

{

// 进入这里意味着电话已经接通，sergeycao一些操作

}

mLastCallState = ringCallState.isRinging() ringCallState:fgCallState;
