我们在使用Android手机打电话时,有时可能会需要对来去电通话自动录音,本文就详细讲解实现Android来去电通话自动录音的方法,大家按照文中的方法编写程序就可以完成此功能。
来去电自动录音的关键在于如何监听手机电话状态的转变:
1)来电的状态的转换如下(红色标记是我们要用到的状态)
空闲(IDEL)——> 响铃(RINGING)——> 接听(ACTIVE)——> 挂断(经历DISCONNECTING——DISCONNECTED)——> 空闲(IDEL)
或者 空闲(IDEL)——> 响铃(RINGING)——> 拒接 ——> 空闲(IDEL)
2)去电状态的转换如下
空闲(IDEL)——> 拨号 (DIALING)——> (对方)响铃(ALERTING) ——> 建立连接(ACTIVE)—— 挂断(经历DISCONNECTING——DISCONNECTED)——> 空闲(IDEL)
或者 空闲(IDEL)——> 拨号 (DIALING)——> (对方)响铃(ALERTING)——> 挂断/对方拒接 ——> 空闲(IDEL)
下面就分别就来电和去电这两种状态分析并实现。
1、先进行来电的分析和实现。
相对去电来说,来电状态的转换检测要简单些。android api 中的PhoneStateListener 类提供了相应的方法,但我们需要覆盖其中的 onCallStateChanged(int state, String incomingNumber) 方法即可实现来电状态的检测,并在此基础上添加录音功能即可。其中 state 参数就是各种电话状态,到时我们将它跟下面我们要用到的状态进行比较,若是电话处在我们想要的状态上,则进行一系列操作,否则就不管他。想要获取这些状态,还需要另一个电话相关类,那就是 TelephonyManager, 该类 提供了一些电话状态,其中我们要用到的是:TelephonyManager.CALL_STATE_IDLE(空闲)、TelephonyManager.CALL_STATE_OFFHOOK(摘机)和 TelephonyManager.CALL_STATE_RINGING(来电响铃)这三个状态。判别这三种状态,可以继承 android.telephony.PhoneStateListener 类,实现上面提到的 onCallStateChanged(int state, String incomingNumber) 方法,请看如下代码:
Java代码
- public class TelListener extends PhoneStateListener {
-
- @Override
- public void onCallStateChanged(int state, String incomingNumber) {
- super.onCallStateChanged(state, incomingNumber);
-
- switch (state) {
- case TelephonyManager.CALL_STATE_IDLE:
- Log.i("TelephoneState", "IDLE");
-
- break;
- case TelephonyManager.CALL_STATE_RINGING:
- Log.i("TelephoneState", "RINGING");
-
- break;
- case TelephonyManager.CALL_STATE_OFFHOOK:
- Log.i("TelephoneState", "OFFHOOK");
-
- break;
- }
-
- Log.i("TelephoneState", String.valueOf(incomingNumber));
- }
-
- }
有了以上来电状态监听代码还不足以实现监听功能,还需要在我们的一个Activity或者Service中实现监听,方法很简单,代码如下:
Java代码
- TelephonyManager telMgr = (TelephonyManager)context.getSystemService(
- Context.TELEPHONY_SERVICE);
- telMgr.listen(new TelListener(), PhoneStateListener.LISTEN_CALL_STATE);
这样就实现了来电状态监听功能,但要能够在设备中跑起来,这还不够,它还需要两个获取手机电话状态的权限:
XML/HTML代码
- <uses-permission android:name="android.permission.READ_PHONE_STATE" />
- <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
这样的话就可以跑起来了。
说到这,我想如果你可以实现录音功能的话,在此基础上实现来电自动录音就应该没什么问题了,不过请容我简单罗嗦几句。既然是来电,那么要想录音的话,那么应该就是在监听到 TelephonyManager.CALL_STATE_OFFHOOK 的状态时开启录音机开始录音, 在监听到TelephonyManager.CALL_STATE_IDLE 的状态时关闭录音机停止录音。这样,来电录音功能就完成了,不要忘记录音功能同样需要权限:
XML/HTML代码
- <uses-permission android:name="android.permission.RECORD_AUDIO"/>
-
- <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
- <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
2、介绍完了来电自动录音,下面就来介绍去电自动录音的实现方法。
上面说过,相比来电状态的监听,去电的要麻烦些,甚至这种方法不是通用的,这个主要是因为android api 中没有提供去电状态监听的相应类和方法(也许我刚接触,没有找到)。刚开始网上搜索了一通也没有找到对应的解决方法,大多是 来电监听的,也就是上面的方法。不过中途发现一篇博文(后来就搜不到了),记得是查询系统日志的方式,从中找到去电过程中的各个状态的关键词。无奈之中,最终妥协了此方法。
我的(联想A65上的)去电日志内容如下:

从上面的日志可以看到,每一行的末尾的大写英文词就是去电的状态,状态说明如下:
DIALING 拨号,对方还未响铃
ACTIVE 对方接通,通话建立
DISCONNECTING 通话断开时
DISCONNECTED 通话已断开,可以认为是挂机了
由于我拨打的是10010,没有响铃过程(电脑自动接通的够快),还少了一个状态,状态是ALERTING ,这个就是对方正在响铃的状态。
有了这几个去电状态就好办了,现在我们要做的就是读取系统日志,然后找到这些状态,提取的关键词就是上面提到的 mforeground(前台通话状态) 和 mbackground (后台通话状态)(可能不一样的设备生成的不一样,根据自己具体设备设置,这里只提取前台的),如果读取的这一行日志中 包含 mforground ,再看看是否包含上面的状态的单词。既然说的如此,那么看看读取系统日志的代码吧。

-
-
-

-

- }
- }
- }
以上代码中,之所以用线程,是为了防止读取日志过程中阻滞主方法的其他方法的执行,影响到程序捕捉对应的电话状态。
好了,捕捉到了去电过程中各个状态的转变,那么,如何通知给程序呢,我采用的方法是捕获后立马给系统发送广播,然后程序进行广播接收,接收后再处理录音事件。要发送广播,就要发送一个唯一的广播,为此,建立如下类:
Java代码
- package com.sdvdxl.outgoingcall;
-
- import com.sdvdxl.phonerecorder.ReadLog;
-
- import android.content.Context;
- import android.util.Log;
-
- public class OutgoingCallState {
- Context ctx;
- public OutgoingCallState(Context ctx) {
- this.ctx = ctx;
- }
-
-
- public static final class ForeGroundCallState {
- public static final String DIALING =
- "com.sdvdxl.phonerecorder.FORE_GROUND_DIALING";
- public static final String ALERTING =
- "com.sdvdxl.phonerecorder.FORE_GROUND_ALERTING";
- public static final String ACTIVE =
- "com.sdvdxl.phonerecorder.FORE_GROUND_ACTIVE";
- public static final String IDLE =
- "com.sdvdxl.phonerecorder.FORE_GROUND_IDLE";
- public static final String DISCONNECTED =
- "com.sdvdxl.phonerecorder.FORE_GROUND_DISCONNECTED";
- }
-
-
- public void startListen() {
- new ReadLog(ctx).start();
- Log.d("Recorder", "开始监听呼出状态的转变,并在对应状态发送广播");
- }
-
- }
程序需要读取系统日志权限:
XML/HTML代码
- <uses-permission android:name="android.permission.READ_LOGS"/>
然后,在读取日志的类中检测到去电各个状态的地方发送一个广播,那么,读取日志的完整代码如下:
Java代码
- package com.sdvdxl.phonerecorder;
-
- import java.io.BufferedReader;
- import java.io.IOException;
- import java.io.InputStream;
- import java.io.InputStreamReader;
-
- import com.sdvdxl.outgoingcall.OutgoingCallState;
-
- import android.content.Context;
- import android.content.Intent;
- import android.util.Log;
-
- public class ReadLog extends Thread {
- private Context ctx;
- private int logCount;
-
- private static final String TAG = "LogInfo OutGoing Call";
-
-
- private static class CallViewState {
- public static final String FORE_GROUND_CALL_STATE = "mForeground";
- }
-
-
- private static class CallState {
- public static final String DIALING = "DIALING";
- public static final String ALERTING = "ALERTING";
- public static final String ACTIVE = "ACTIVE";
- public static final String IDLE = "IDLE";
- public static final String DISCONNECTED = "DISCONNECTED";
- }
-
- public ReadLog(Context ctx) {
- this.ctx = ctx;
- }
-
-
- @Override
- public void run() {
- Log.d(TAG, "开始读取日志记录");
-
- String[] catchParams = {"logcat", "InCallScreen *:s"};
- String[] clearParams = {"logcat", "-c"};
-
- try {
- Process process=Runtime.getRuntime().exec(catchParams);
- InputStream is = process.getInputStream();
- BufferedReader reader = new BufferedReader(new InputStreamReader(is));
-
- String line = null;
- while ((line=reader.readLine())!=null) {
- logCount++;
-
- Log.v(TAG, line);
-
-
- if (logCount>512) {
-
- Runtime.getRuntime().exec(clearParams)
- .destroy();
- logCount = 0;
- Log.v(TAG, "-----------清理日志---------------");
- }
-
-
-
- if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE)
- && line.contains(ReadLog.CallState.IDLE)) {
- Log.d(TAG, ReadLog.CallState.IDLE);
- }
-
-
- if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE)
- && line.contains(ReadLog.CallState.DIALING)) {
-
- Intent dialingIntent = new Intent();
- dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.DIALING);
- ctx.sendBroadcast(dialingIntent);
-
- Log.d(TAG, ReadLog.CallState.DIALING);
- }
-
-
- if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE)
- && line.contains(ReadLog.CallState.ALERTING)) {
-
- Intent dialingIntent = new Intent();
- dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.ALERTING);
- ctx.sendBroadcast(dialingIntent);
-
- Log.d(TAG, ReadLog.CallState.ALERTING);
- }
-
-
- if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE)
- && line.contains(ReadLog.CallState.ACTIVE)) {
-
- Intent dialingIntent = new Intent();
- dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.ACTIVE);
- ctx.sendBroadcast(dialingIntent);
-
- Log.d(TAG, ReadLog.CallState.ACTIVE);
- }
-
-
- if (line.contains(ReadLog.CallViewState.FORE_GROUND_CALL_STATE)
- && line.contains(ReadLog.CallState.DISCONNECTED)) {
-
- Intent dialingIntent = new Intent();
- dialingIntent.setAction(OutgoingCallState.ForeGroundCallState.DISCONNECTED);
- ctx.sendBroadcast(dialingIntent);
-
- Log.d(TAG, ReadLog.CallState.DISCONNECTED);
- }
-
- }
-
- } catch (IOException e) {
- e.printStackTrace();
- }
- }
- }
发送了广播,那么就要有接收者,定义接收者如下(关于录音机的代码可以先忽略):
Java代码
- package com.sdvdxl.phonerecorder;
-
- import android.content.BroadcastReceiver;
- import android.content.Context;
- import android.content.Intent;
- import android.util.Log;
-
- import com.sdvdxl.outgoingcall.OutgoingCallState;
-
- public class OutgoingCallReciver extends BroadcastReceiver {
- static final String TAG = "Recorder";
- private MyRecorder recorder;
-
- public OutgoingCallReciver() {
- recorder = new MyRecorder();
- }
-
- public OutgoingCallReciver (MyRecorder recorder) {
- this.recorder = recorder;
- }
-
- @Override
- public void onReceive(Context ctx, Intent intent) {
- String phoneState = intent.getAction();
-
- if (phoneState.equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
- String phoneNum = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
- recorder.setPhoneNumber(phoneNum);
- recorder.setIsCommingNumber(false);
- Log.d(TAG, "设置为去电状态");
- Log.d(TAG, "去电状态 呼叫:" + phoneNum);
- }
-
- if (phoneState.equals(OutgoingCallState.ForeGroundCallState.DIALING)) {
- Log.d(TAG, "正在拨号...");
- }
-
- if (phoneState.equals(OutgoingCallState.ForeGroundCallState.ALERTING)) {
- Log.d(TAG, "正在呼叫...");
- }
-
- if (phoneState.equals(OutgoingCallState.ForeGroundCallState.ACTIVE)) {
- if (!recorder.isCommingNumber() && !recorder.isStarted()) {
- Log.d(TAG, "去电已接通 启动录音机");
- recorder.start();
-
- }
- }
-
- if (phoneState.equals(OutgoingCallState.ForeGroundCallState.DISCONNECTED)) {
- if (!recorder.isCommingNumber() && recorder.isStarted()) {
- Log.d(TAG, "已挂断 关闭录音机");
- recorder.stop();
- }
- }
- }
-
- }
其中有这么一段代码:
Java代码
- String phoneState = intent.getAction();
-
- if (phoneState.equals(Intent.ACTION_NEW_OUTGOING_CALL)) {
- String phoneNum = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
- recorder.setPhoneNumber(phoneNum);
- recorder.setIsCommingNumber(false);
- Log.d(TAG, "设置为去电状态");
- Log.d(TAG, "去电状态 呼叫:" + phoneNum);
- }
这里是接收系统发出的广播,用于接收去电广播。这样,就获得了去电状态。
3、有了以上主要代码,可以说,来去电监听功能算是完成了,下面创建一个service来运行监听:
Java代码
- package com.sdvdxl.service;
-
- import android.app.Service;
- import android.content.Context;
- import android.content.Intent;
- import android.content.IntentFilter;
- import android.os.IBinder;
- import android.telephony.PhoneStateListener;
- import android.telephony.TelephonyManager;
- import android.util.Log;
- import android.widget.Toast;
-
- import com.sdvdxl.outgoingcall.OutgoingCallState;
- import com.sdvdxl.phonerecorder.MyRecorder;
- import com.sdvdxl.phonerecorder.OutgoingCallReciver;
- import com.sdvdxl.phonerecorder.TelListener;
-
- public class PhoneCallStateService extends Service {
- private OutgoingCallState outgoingCallState;
- private OutgoingCallReciver outgoingCallReciver;
- private MyRecorder recorder;
-
- @Override
- public void onCreate() {
- super.onCreate();
-
-
-
-
- Log.d("Recorder", "正在监听中...");
- recorder = new MyRecorder();
- outgoingCallState = new OutgoingCallState(this);
- outgoingCallReciver = new OutgoingCallReciver(recorder);
- outgoingCallState.startListen();
- Toast.makeText(this, "服务已启动", Toast.LENGTH_LONG).show();
-
-
- IntentFilter outgoingCallFilter = new IntentFilter();
- outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.IDLE);
- outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.DIALING);
- outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.ALERTING);
- outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.ACTIVE);
- outgoingCallFilter.addAction(OutgoingCallState.ForeGroundCallState.DISCONNECTED);
-
- outgoingCallFilter.addAction("android.intent.action.PHONE_STATE");
- outgoingCallFilter.addAction("android.intent.action.NEW_OUTGOING_CALL");
-
-
- registerReceiver(outgoingCallReciver, outgoingCallFilter);
-
-
- TelephonyManager telmgr = (TelephonyManager)getSystemService(
- Context.TELEPHONY_SERVICE);
- telmgr.listen(new TelListener(recorder), PhoneStateListener.LISTEN_CALL_STATE);
-
-
- }
-
- @Override
- public IBinder onBind(Intent intent) {
-
- return null;
- }
-
- @Override
- public void onDestroy() {
- super.onDestroy();
- unregisterReceiver(outgoingCallReciver);
- Toast.makeText(
- this, "已关闭电话监听服务", Toast.LENGTH_LONG)
- .show();
- Log.d("Recorder", "已关闭电话监听服务");
- }
-
- @Override
- public int onStartCommand(Intent intent, int flags, int startId) {
-
- return START_STICKY;
- }
-
- }
注册以下service:
XML/HTML代码
- <service android:name="com.sdvdxl.service.PhoneCallStateService" />
到此为止,来去电状态的监听功能算是完成了,剩下一个录音机,附上录音机代码如下:
到此,来去电通话自动录音的所有功能就完成了,大家可以自己试着编写并实现。
