我觉得写文章就得写得有用一些的，必须要有自己的思想，关于来电去电监听将按照下面三个问题展开 1、监听来电去电有什么用？ 2、怎么监听，来电去电监听方式一样吗？ 3、实战，有什么需要特别注意地方？一、监听来电去电能干什么 1、能够对监听到的电话做个标识，告诉用户这个电话是诈骗、推销、广告什么的 2、能够针对那些特殊的电话进行自动挂断，避免打扰到用户二、来电去电的监听方式（不一样的方式） 2.1 来去电监听方式一（PhoneStateListener）　　来电监听是使用PhoneStateListener类，使用方式是，将PhoneStateListener对象（一般是自己继承PhoneStateListener类完成一些封装）注册到系统电话管理服务中去（TelephonyManager）　　然后通过PhoneStateListener的回调方法onCallStateChanged(int state, String incomingNumber) 实现来电的监听（详细实现可以参考后面给出的拓展阅读部分） 注册监听

private void registerPhoneStateListener() {
    CustomPhoneStateListener customPhoneStateListener = new CustomPhoneStateListener(this);
    TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
    if (telephonyManager != null) {
        telephonyManager.listen(customPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
    }
}

PhoneStateListener的onCallStateChanged方法监听来电状态

package com.phone.listen;

import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.ServiceState;
import android.telephony.TelephonyManager;
import android.util.Log;

/**
 * 来去电监听
 */
public class CustomPhoneStateListener extends PhoneStateListener {

    private Context mContext;

    public CustomPhoneStateListener(Context context) {
        mContext = context;
    }

    @Override
    public void onServiceStateChanged(ServiceState serviceState) {
        super.onServiceStateChanged(serviceState);
        Log.d(PhoneListenService.TAG, "CustomPhoneStateListener onServiceStateChanged: " + serviceState);
    }

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
        Log.d(PhoneListenService.TAG, "CustomPhoneStateListener state: " 
              + state + " incomingNumber: " + incomingNumber);
        switch (state) {
            case TelephonyManager.CALL_STATE_IDLE:      // 电话挂断
                break;
            case TelephonyManager.CALL_STATE_RINGING:   // 电话响铃
                Log.d(PhoneListenService.TAG, "CustomPhoneStateListener onCallStateChanged endCall");
                HangUpTelephonyUtil.endCall(mContext);
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:   // 来电接通 或者 去电，去电接通  但是没法区分
                break;
        }
    }
}

三种状态源码解释

/** Device call state: No activity. */
public static final int CALL_STATE_IDLE = 0;    // 电话挂断
/** Device call state: Ringing. A new call arrived and is
 *  ringing or waiting. In the latter case, another call is
 *  already active. */
public static final int CALL_STATE_RINGING = 1;    // 来电响铃
/** Device call state: Off-hook. At least one call exists
  * that is dialing, active, or on hold, and no calls are ringing
  * or waiting. */
public static final int CALL_STATE_OFFHOOK = 2;    // 来电接通 或者 去电拨号 但是没法区分出来

2.2 来去电方式二（广播监听）

<receiver android:name=".PhoneStateReceiver"
    android:enabled="true"
    android:process=":PhoneListenService">
    <intent-filter>
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        <action android:name="android.intent.action.PHONE_STATE" />
    intent-filter>
receiver>

package com.phone.listen;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;
import android.util.Log;

/**
 * Created by popfisher on 2017/11/6.
 */

public class PhoneStateReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        Log.d(PhoneListenService.TAG, "PhoneStateReceiver action: " + action);

        String resultData = this.getResultData();
        Log.d(PhoneListenService.TAG, "PhoneStateReceiver getResultData: " + resultData);

        if (action.equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
            // 去电，可以用定时挂断
            // 双卡的手机可能不走这个Action
            String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            Log.d(PhoneListenService.TAG, "PhoneStateReceiver EXTRA_PHONE_NUMBER: " + phoneNumber);
        } else {
            // 来电去电都会走
            // 获取当前电话状态
            String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
            Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive state: " + state);

            // 获取电话号码
            String extraIncomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
            Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive extraIncomingNumber: " + extraIncomingNumber);

            if (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING)) {
                Log.d(PhoneListenService.TAG, "PhoneStateReceiver onReceive endCall");
                HangUpTelephonyUtil.endCall(context);
            }
        }
    }
}

三、实战，有什么需要特别注意地方 3.1 双卡双待的手机怎么获取　　对于双卡手机，每张卡都对应一个Service和一个PhoneStateListener，需要给每个服务注册自己的PhoneStateListener，服务的名称还会有点变化，厂商可能会修改
　　

public ArrayList<String> getMultSimCardInfo() {
    // 获取双卡的信息，这个也是经验尝试出来的，不知道其他厂商有什么坑
    ArrayList<String> phoneServerList = new ArrayList<String>();
    for(int i = 1; i < 3; i++) {
        try {
            String phoneServiceName;
            if (MiuiUtils.isMiuiV6()) {
                phoneServiceName = "phone." + String.valueOf(i-1);
            } else {
                phoneServiceName = "phone" + String.valueOf(i);
            }

            // 尝试获取服务看是否能获取到
            IBinder iBinder = ServiceManager.getService(phoneServiceName);
            if(iBinder == null) continue;

            ITelephony iTelephony = ITelephony.Stub.asInterface(iBinder);
            if(iTelephony == null) continue;

            phoneServerList.add(phoneServiceName);
        } catch(Exception e) {
            e.printStackTrace();
        }
    }
    // 这个是默认的
    phoneServerList.add(Context.TELEPHONY_SERVICE);
    return phoneServerList;
}

3.2 挂断电话　　挂断电话使用系统服务提供的接口去挂断，但是挂断电话是个并不能保证成功的方法，所以会有多种方式挂断同时使用，下面提供
　　

package com.phone.listen;

import android.content.Context;
import android.os.RemoteException;
import android.telephony.TelephonyManager;

import com.android.internal.telephony.ITelephony;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.concurrent.Executor;
import java.util.concurrent.Executors;

/**
 * 封装挂断电话接口
 */
public class HangUpTelephonyUtil {
    public static boolean endCall(Context context) {
        boolean callSuccess = false;
        ITelephony telephonyService = getTelephonyService(context);
        try {
            if (telephonyService != null) {
                callSuccess = telephonyService.endCall();
            }
        } catch (RemoteException e) {
            e.printStackTrace();
        } catch (Exception e){
            e.printStackTrace();
        }
        if (callSuccess == false) {
            Executor eS = Executors.newSingleThreadExecutor();
            eS.execute(new Runnable() {
                @Override
                public void run() {
                    disconnectCall();
                }
            });
            callSuccess = true;
        }
        return callSuccess;
    }

    private static ITelephony getTelephonyService(Context context) {
        TelephonyManager telephonyManager = (TelephonyManager) 
　　　　　　　　　　　　　　context.getSystemService(Context.TELEPHONY_SERVICE);
        Class clazz;
        try {
            clazz = Class.forName(telephonyManager.getClass().getName());
            Method method = clazz.getDeclaredMethod("getITelephony");
            method.setAccessible(true);
            return (ITelephony) method.invoke(telephonyManager);
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
        return null;
    }

    private static boolean disconnectCall() {
        Runtime runtime = Runtime.getRuntime();
        try {
            runtime.exec("service call phone 5 
");
        } catch (Exception exc) {
            exc.printStackTrace();
            return false;
        }
        return true;
    }

    // 使用endCall挂断不了，再使用killCall反射调用再挂一次
    public static boolean killCall(Context context) {
        try {
            // Get the boring old TelephonyManager
            TelephonyManager telephonyManager = (TelephonyManager) 
　　　　　　　　　　　　context.getSystemService(Context.TELEPHONY_SERVICE);

            // Get the getITelephony() method
            Class classTelephony = Class.forName(telephonyManager.getClass().getName());
            Method methodGetITelephony = classTelephony.getDeclaredMethod("getITelephony");

            // Ignore that the method is supposed to be private
            methodGetITelephony.setAccessible(true);

            // Invoke getITelephony() to get the ITelephony interface
            Object telephonyInterface = methodGetITelephony.invoke(telephonyManager);

            // Get the endCall method from ITelephony
            Class telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
            Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("endCall");

            // Invoke endCall()
            methodEndCall.invoke(telephonyInterface);
        } catch (Exception ex) { // Many things can go wrong with reflection calls
            return false;
        }
        return true;
    }
}

　ITelephony接口在layoutlib.jar包中，需要导入 android sdk目录platformsandroid-8datalayoutlib.jar 挂断电话需要权限 <uses-permission android:name="android.permission.CALL_PHONE" /> 3.3 监听来去电状态放到后台服务（独立进程）

".PhoneListenService"
            android:label="Android来电监听"
            android:process=":PhoneListenService"/>

来去电监听Service

package com.phone.listen;

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;

/**
 * 来去电监听服务
 */
public class PhoneListenService extends Service {

    public static final String TAG = PhoneListenService.class.getSimpleName();

    public static final String ACTION_REGISTER_LISTENER = "action_register_listener";

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d(TAG, "onCreate");
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d(TAG, "onStartCommand action: " + intent.getAction() + 
　　　　　　　　　　" flags: " + flags + " startId: " + startId);
        String action = intent.getAction();
        if (action.equals(ACTION_REGISTER_LISTENER)) {
            registerPhoneStateListener();
        }
        return super.onStartCommand(intent, flags, startId);
    }

    private void registerPhoneStateListener() {
        CustomPhoneStateListener customPhoneStateListener = new CustomPhoneStateListener(this);
        TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        if (telephonyManager != null) {
            telephonyManager.listen(customPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
        }
    }
}

3.4 整体配置文件


<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.phone.listen">
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
