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
