android 实现监听电话

//先取得服务
TelephonyManager telManage = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);

//设置监听
telManage.listen(new phoneListen(),PhoneStateListener.LISTEN_CALL_STATE);

//实现监听
class phoneListen extends PhoneStateListener{
//每次状态变化时将会调用一次
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch(state){
case TelephonyManager.CALL_STATE_IDLE:			//闲着
break;
case TelephonyManager.CALL_STATE_OFFHOOK:		//接听时
break;
case TelephonyManager.CALL_STATE_RINGING:		//有来电时
break;
}
super.onCallStateChanged(state, incomingNumber);
}
}
