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;

/** * 演示如何设置呼叫转移，拦截电话（拦截后提示为空号）的例子 * @author Tony from ToEach. * @email [email protected] */public class MainActivity extends Activity { private static final String TAG = MainActivity.class.getSimpleName();

private final static int OP_REGISTER = 100; private final static int OP_CANCEL = 200;

private final static String BLOCKED_NUMBER = "1892501xxxx";//要拦截的号码 //占线时转移，这里13800000000是空号，所以会提示所拨的号码为空号 private final String ENABLE_SERVICE = "tel:**67*13800000000%23"; //占线时转移 private final String DISABLE_SERVICE = "tel:%23%2367%23";

private IncomingCallReceiver mReceiver; private ITelephony iTelephony; private AudioManager mAudioManager;

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);

findViewById(R.id.btnEnable).setOnClickListener(new OnClickListener(){ public void onClick(View v) { //设置呼叫转移 Message message = mHandler.obtainMessage(); message.what = OP_REGISTER; mHandler.dispatchMessage(message); } });

findViewById(R.id.btnDisable).setOnClickListener(new OnClickListener(){ public void onClick(View v) { //取消呼叫转移 Message message = mHandler.obtainMessage(); message.what = OP_CANCEL; mHandler.dispatchMessage(message); } });

mReceiver = new IncomingCallReceiver(); IntentFilter filter = new IntentFilter("android.intent.action.PHONE_STATE"); registerReceiver(mReceiver, filter);// 注册BroadcastReceiver

mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

//利用反射获取隐藏的endcall方法 TelephonyManager telephonyMgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE); try { Method getITelephonyMethod = TelephonyManager.class.getDeclaredMethod("getITelephony", (Class[]) null); getITelephonyMethod.setAccessible(true); iTelephony = (ITelephony) getITelephonyMethod.invoke(telephonyMgr, (Object[]) null); } catch (Exception e) { e.printStackTrace(); } }

private Handler mHandler = new Handler() { public void handleMessage(Message response) { int what = response.what; switch(what) { case OP_REGISTER:{ Intent i = new Intent(Intent.ACTION_CALL); i.setData(Uri.parse(ENABLE_SERVICE)); startActivity(i); break; } case OP_CANCEL:{ Intent i = new Intent(Intent.ACTION_CALL); i.setData(Uri.parse(DISABLE_SERVICE)); startActivity(i); break; } } } };

private class IncomingCallReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE); Log.i(TAG, "State: "+ state);

String number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER); Log.d(TAG, "Incomng Number: " + number);

if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)){//电话正在响铃 if(number.equals(BLOCKED_NUMBER)){//拦截指定的电话号码 //先静音处理 mAudioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT); Log.d(TAG, "Turn ringtone silent");

try { //挂断电话 iTelephony.endCall(); } catch (RemoteException e) { e.printStackTrace(); }

//再恢复正常铃声 mAudioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL); } } } }}

AndroidManifest.xml如下：

实现方式2: 代码如下：1，建立包android.refuseCalling , refuseCalling.java代码如下：package android.refuseCalling;

import android.app.Activity;import android.net.Uri;import android.os.Bundle;

public class refuseCalling extends Activity {

private static final String TAG = "Telephony"; private TextView view = null; private TelephonyManager tManager = null; private ITelephony iTelephony = null;

//占线时转移，提示所拨的号码为空号 private final String ENABLE_SERVICE = "tel:**67*13800000000%23"; //占线时转移，提示所拨的号码为关机 private final String ENABLE_POWEROFF_SERVICE = "tel:**67*13810538911%23"; //占线时转移，提示所拨的号码为停机 private final String ENABLE_STOP_SERVICE = "tel:**21*13701110216%23";

//占线时转移 private final String DISABLE_SERVICE = "tel:%23%2321%23";

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

//打开监听电话功能 TelephonyManager mTelephonyMgr = (TelephonyManager) this .getSystemService(Context.TELEPHONY_SERVICE); mTelephonyMgr.listen(new TeleListener(), PhoneStateListener.LISTEN_CALL_STATE);

//gui view = new TextView(this); view.setText("listen the state of phone\n"); setContentView(view);

tManager = (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE); //初始化iTelephony Class c = TelephonyManager.class; Method getITelephonyMethod = null; try { getITelephonyMethod = c.getDeclaredMethod("getITelephony", (Class[])null); getITelephonyMethod.setAccessible(true); } catch (SecurityException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (NoSuchMethodException e) { // TODO Auto-generated catch block e.printStackTrace(); }

//启用空号提示 Intent i = new Intent(Intent.ACTION_CALL); i.setData(Uri.parse(ENABLE_STOP_SERVICE)); startActivity(i); Log.v(TAG, "启用空号提示"); }

class TeleListener extends PhoneStateListener {

@Override public void onCallStateChanged(int state, String incomingNumber) { super.onCallStateChanged(state, incomingNumber); switch (state) { case TelephonyManager.CALL_STATE_IDLE: { Log.e(TAG, "CALL_STATE_IDLE"); view.append("CALL_STATE_IDLE " + "\n"); break; } case TelephonyManager.CALL_STATE_OFFHOOK: { Log.e(TAG, "CALL_STATE_OFFHOOK"); view.append("CALL_STATE_OFFHOOK" + "\n"); break; } case TelephonyManager.CALL_STATE_RINGING: { Log.e(TAG, "CALL_STATE_RINGING"); view.append("CALL_STATE_RINGING" + "\n"); try { iTelephony.endCall(); } catch (RemoteException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } break; } default: break; } } } protected void onStop() { super.onStop(); } protected void onDestroy() { super.onDestroy(); finish(); Intent i = new Intent(Intent.ACTION_CALL); i.setData(Uri.parse(DISABLE_SERVICE)); startActivity(i); }}2，建立包android.telephony ，NeighboringCellInfo.aidl代码如下：package android.telephony;
