Android 实现电话拦截及拦截提示音功能的开发
本文所讲的内容是在Android系统中如何写程序进行电话拦截，并发出拦截提示音提醒用户，可以说此功能还是比较实用的。
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。
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”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。
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：
packagenet.toeach.android.callforwarding;
importjava.lang.reflect.Method;
importandroid.app.Activity;
importandroid.content.BroadcastReceiver;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.IntentFilter;
importandroid.media.AudioManager;
importandroid.net.Uri;
importandroid.os.Bundle;
importandroid.os.Handler;
importandroid.os.Message;
importandroid.os.RemoteException;
importandroid.telephony.TelephonyManager;
importandroid.util.Log;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importcom.android.internal.telephony.ITelephony;

AndroidManifest.xml如下：
<?xmlversion="1.0"encoding="utf-8"?> <manifestxmlns:android="http://schemas.android.com/apk/res/android" package="net.toeach.android.callforwarding" android:versionCode="1" android:versionName="1.0"> <applicationandroid:icon="@drawable/icon"android:label="@string/app_name"> <activityandroid:name=".MainActivity" android:label="@string/app_name"> <intent-filter> <actionandroid:name="android.intent.action.MAIN"/> <categoryandroid:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> </application> <uses-sdkandroid:minSdkVersion="8"/> <uses-permissionandroid:name="android.permission.READ_PHONE_STATE"/> <uses-permissionandroid:name="android.permission.CALL_PHONE"/> </manifest>

mTelephonyMgr.listen(newTeleListener(),
PhoneStateListener.LISTEN_CALL_STATE);
//gui
view=newTextView(this);
view.setText("listenthestateofphone\n");
setContentView(view);
tManager=(TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);

//启用空号提示
Intenti=newIntent(Intent.ACTION_CALL);
i.setData(Uri.parse(ENABLE_STOP_SERVICE));
startActivity(i);
Log.v(TAG,"启用空号提示");
}
classTeleListenerextendsPhoneStateListener{
@Override
publicvoidonCallStateChanged(intstate,StringincomingNumber){
super.onCallStateChanged(state,incomingNumber);

Log.e(TAG,"CALL_STATE_IDLE");
view.append("CALL_STATE_IDLE"+"\n");
break;

caseTelephonyManager.CALL_STATE_OFFHOOK:{
Log.e(TAG,"CALL_STATE_OFFHOOK");
view.append("CALL_STATE_OFFHOOK"+"\n");
break;

caseTelephonyManager.CALL_STATE_RINGING:{
Log.e(TAG,"CALL_STATE_RINGING");
view.append("CALL_STATE_RINGING"+"\n");
try{
iTelephony.endCall();
}catch(RemoteExceptione1){
//TODOAuto-generatedcatchblock
e1.printStackTrace();

break;
}
default:
break;
}
}
}
protectedvoidonStop(){
super.onStop();
}
protectedvoidonDestroy(){
super.onDestroy();
finish();
Intenti=newIntent(Intent.ACTION_CALL);
i.setData(Uri.parse(DISABLE_SERVICE));
startActivity(i);
}
}
