需要用Aidl，來與系統(tǒng)進程進行交互

（關(guān)于aidl的介紹：

http://chenfeng0104.iteye.com/blog/1255302

http://www.cnblogs.com/mydomainlistentome/p/4687173.html）

首先在src下建立這樣的包：

　　com.android.internal.telephony

然后在這個包下建立這樣的aidl文件：

　　ITelephony.aidl

package com.android.internal.telephony ;
interface ITelephony {
    boolean endCall() ;    // 掛斷電話
    void answerRingingCall() ;    // 撥打電話
}

利用反射，在后臺打印出隱藏的可以掛斷電話的private類型的方法

private ITelephony getITelephony() {
    ITelephony iTelephony=null;
    Class<TelephonyManager> cls=TelephonyManager.class;
    Method [] method= cls.getDeclaredMethods();
    for(int i=0;i<method.length;i++){
        System.out.println("方法："+method[i]);
    }

找到這個方法：

I/System.out(1406): 方法：private com.android.internal.telephony.ITelephony android.telephony.TelephonyManager.getITelephony()
07-31 21:59:27.522: I/System.out(1406): 方法：public static int android.telephony.TelephonyManager.getLteOnCdmaModeStatic()
07-31 21:59:27.522: I/System.out(1406): 方法：public static int android.telephony.TelephonyManager.getNetworkClass(int)
07-31 21:59:27.522: I/System.out(1406): 方法：public static java.lang.String android.telephony.TelephonyManager.getNetworkTypeName(int)
07-31 21:59:27.522: I/System.out(1406): 方法：public static int android.telephony.TelephonyManager.getPhoneType(int)
07-31 21:59:27.522: I/System.out(1406): 方法：private int android.telephony.TelephonyManager.getPhoneTypeFromNetworkType()

然后將這個方法解封，調(diào)用

private ITelephony getITelephony() {
        ITelephony iTelephony = null;
        Class<TelephonyManager> cls = TelephonyManager.class;
        Method method = null;
        // Method [] method= cls.getDeclaredMethods();
        // for(int i=0;i<method.length;i++){
        // System.out.println("方法："+method[i]);
        // }
        try {
            method = cls.getDeclaredMethod("getITelephony");
            // 取消封裝
            method.setAccessible(true);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        try {
            // 使用invoke來執(zhí)行這個私有方法
            iTelephony = (ITelephony) method.invoke(telephone);
            return iTelephony;
        } catch (Exception e) {
            e.printStackTrace();
        }

        return iTelephony;
    }

解決以上的問題就可以實現(xiàn)電話攔截了，下面是全部代碼：

service實現(xiàn)掛斷：

package com.example.phonelistendemo;

import java.lang.reflect.Method;

import com.android.internal.telephony.ITelephony;

import android.content.Intent;

public class ServicePhone extends Service {
    private TelephonyManager telephone = null;
    private AudioManager audio = null;
    private IBinder mbinder = new BinderImpl();
    private String num = null;

    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onDestroy() {
        mbinder = null;
        num = null;
        super.onDestroy();
    }

    public class BinderImpl extends Binder implements IService {
        @Override
        public String getInterfaceDescriptor() {
            return "過濾電話：“" + ServicePhone.this.num + "”設置成功！";
        }
    }

    public IBinder onBind(Intent arg0) {
        audio = (AudioManager) getSystemService(AUDIO_SERVICE);
        num = arg0.getStringExtra("Nums");
        telephone = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
        backGroundExecution();
        return mbinder;
    }

    // 啟動子線程
    public void backGroundExecution() {
        Thread thread = new Thread(null, backGroundProgress, "phoneListener");
        thread.start();
    }

    // 實例化子線程
    private Runnable backGroundProgress = new Runnable() {
        public void run() {
            telephone.listen(new PhoneStateListenerImpl(),
                    PhoneStateListener.LISTEN_CALL_STATE);
        }
    };

    private class PhoneStateListenerImpl extends PhoneStateListener {
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                if (incomingNumber.equals(num)) {
                    ITelephony iTelephony=getITelephony();
                    if(iTelephony!=null){
                        try {
                            //掛斷電話
                            iTelephony.endCall();
                        } catch (RemoteException e) {
                            e.printStackTrace();
                        }
                    }
                }
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                break;
            case TelephonyManager.CALL_STATE_IDLE:

　　　　　　　　　　//掛斷提示音開啟
　　　　　　　　　　//audio.setRingerMode(AudioManager.RINGER_MODE_NORMAL);

　　　　　　　　　　　break;

            }
        }
    }

    private ITelephony getITelephony() {
        ITelephony iTelephony = null;
        Class<TelephonyManager> cls = TelephonyManager.class;
        Method method = null;
        // Method [] method= cls.getDeclaredMethods();
        // for(int i=0;i<method.length;i++){
        // System.out.println("方法："+method[i]);
        // }
        try {
            method = cls.getDeclaredMethod("getITelephony");
            // 取消封裝
            method.setAccessible(true);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
        try {
            // 使用invoke來執(zhí)行這個私有方法
            iTelephony = (ITelephony) method.invoke(telephone);
            return iTelephony;
        } catch (Exception e) {
            e.printStackTrace();
        }

        return iTelephony;
    }

}

broadcastReceive 接收電話狀態(tài)

package com.example.phonelistendemo; 


import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class ReceivePhone extends BroadcastReceiver { 
    public void onReceive(Context content, Intent intent) {
        // 撥打電話
        if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) {
            Intent in=new Intent(content,ServicePhone.class);
            content.startService(in);

        } else{
            Intent in=new Intent(content, ServicePhone.class);
            content.startService(in);
        }
    }

}

定義IService接口 標記綁定狀態(tài)

package com.example.phonelistendemo;

public interface IService {

<uses-permission android:name="android.permission.CALL_PHONE"/>

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
