思路：

对来电进行监控

1）对于通讯录的电话来电不做监控

2）对于通讯录里没有的电话号码进行监控

监控规则：

1）正则匹配如：杭州的本地号码需要接听其他地区来电拒接

2）如果一些确认需要来电的号码但又不想加入黑名单的号码加入白名单管理列表；

3）如果是手机来电，拒接的发送一条短信（询问是何人找我干什么事情？避免误伤），如果是座机就误伤吧！

下面是收集的一些代码片段：

public class PhoneStatReceiver extends BroadcastReceiver{

        private static final String TAG = "PhoneStatReceiver";

//        private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();

        private static boolean incomingFlag = false;

        private static String incoming_number = null;

        @Override
        public void onReceive(Context context, Intent intent) {
                //如果是拨打电话
                if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
                        incomingFlag = false;
                        String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
                        Log.i(TAG, "call OUT:"+phoneNumber);
                }else{     //action.equals(MyBroadcastReceiver.B_PHONE_STATE)
                        //如果是来电
                        TelephonyManager tm =
                            (TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);

                        switch (tm.getCallState()) {
                            case TelephonyManager.CALL_STATE_RINGING:
                                incomingFlag = true;//标识当前是来电
                                incoming_number = intent.getStringExtra("incoming_number");

                                if (isBlock(incoming_number)) {
                                    try {
                                        Method method = Class.forName(
                                                "android.os.ServiceManager").getMethod(
                                                "getService", String.class);
                                        // 获取远程TELEPHONY_SERVICE的IBinder对象的代理
                                        IBinder binder = (IBinder) method.invoke(null,
                                                new Object[] { TELEPHONY_SERVICE });
                                        // 将IBinder对象的代理转换为ITelephony对象
                                        ITelephony telephony = ITelephony.Stub
                                                .asInterface(binder);
                                        // 挂断电话
                                        telephony.endCall();
                                    } catch (Exception e) {
                                        e.printStackTrace();
                                    }
                                }


                                Log.i(TAG, "RINGING :"+ incoming_number);
                                break;
                        case TelephonyManager.CALL_STATE_OFFHOOK:
                                if(incomingFlag){
                                        Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
                                }
                                break;

                        case TelephonyManager.CALL_STATE_IDLE:
                                if(incomingFlag){
                                        Log.i(TAG, "incoming IDLE");
                                }
                                break;
                        }
                }
        }
}
在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，
另外注意加上相应的权限。
<receiver android:name=".filter.PhoneStatReceiver">
            <intent-filter>
                 <action android:name="android.intent.action.PHONE_STATE"/>
                 <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
            </intent-filter>
</receiver>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
        来电分三种状态：
CALL_STATE_RINGING：来电响铃
CALL_STATE_OFFHOOK：摘机
CALL_STATE_IDLE：挂机
