电话拦截以及电话拦截后的提示音
1. 电话拦截
这个功能大家可能都知道了，就是利用反射原理调用ITelephony的隐藏方法来实现。这个就不说了，在附件的代码里有。
2.拦截后提示忙音/空号/已关机/已停机
这个功能其实是要用到MMI指令，具体如何设置呼叫转移的指定可以参考这里 http://baike.baidu.com/view/206402.html?fromTaglist 。
在 本文中我们会用到“遇忙转移”转移的功能。中国移动的设置方式是 **67#电话号码#，取消方式为 ##67#。”无条件转移“用21代替67即可。这两个指令可以直接在手机的拨号界面输入并拨号测试。ITelephony的endcall方法挂断电话 后，会提示电话忙。如果事前设置好了忙时转移到一个空号/已关机/已停机的电话号码，就会提示您拨的电话号码是空号/已关机/已停机。
其实大家可以下载 xxx卫士看下，它设置来电拒接模式后，都是会启动设置MMI指令的界面。然后再去“设置》通话设置》来电转接”，看看 “占线时转接” 设置好的电话号码，就可以知道空号/已关机/已停机对应的电话号码是什么了。
附件是演示工程文件，有几点要说明下：
1. 修改一下BLOCKED_NUMBER这个变量值，把它设置为你要测试拦截的电话号码。
2. 全部功能是在一个Activity里实现的，所以大家要先运行这个Activity，然后点击“设置呼叫转移”，设置好呼叫转移后，不要关闭这个Activity，关了就拦截不了电话了。有心的朋友可以自己去写一个Service在后台运行拦截功能。
实现方式1：
代码如下：
package net.toeach.android.callforwarding;
import java.lang.reflect.Method;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.media.AudioManager;
import android.net.Uri;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.os.RemoteException;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import com.android.internal.telephony.ITelephony;
