本文介绍了如何在Android中实现通话录音，包括注册通话状态广播接收器、处理通话录音的代码逻辑，以及启动和停止录音服务的方法。通过监听电话状态，使用MediaRecorder进行录音，并在通话结束后保存录音文件。

一：通话录音状态广播注册

二：通话录音代码

public class PhoneReceiver extends BroadcastReceiver {
   public static final String INTENT_PHONE_STR = "phone";
   public static final String INTENT_STATE_BOOL = "state";
   //手机号
   private static String phone;
   //是否拨打电话
   private static boolean isDial;

   @Override
   public void onReceive(Context context, Intent intent) {
       // 数据为空处理
       if (intent == null) {
           intent = new Intent();
       }

       if (Intent.ACTION_NEW_OUTGOING_CALL.equals(intent.getAction())) {// 打出号码
           String curPhone = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
           phone = curPhone;
           isDial = true;
           return;
       }

       // 电话监听
       TelephonyManager telMgr = (TelephonyManager) context
               .getSystemService(Service.TELEPHONY_SERVICE);
       switch (telMgr.getCallState()) {
       case TelephonyManager.CALL_STATE_RINGING:// 打进号码
           String number = intent
                   .getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
           LogUtil.e("TelephonyManager.CALL_STATE_RINGING" + number);
           phone = number;
           isDial = false;
           break;
       case TelephonyManager.CALL_STATE_OFFHOOK:
           LogUtil.e("TelephonyManager.CALL_STATE_OFFHOOK");
           Intent i = new Intent(context, RecorderService.class);
           i.putExtra(INTENT_PHONE_STR, phone);
           i.putExtra(INTENT_STATE_BOOL, isDial);
           context.startService(i);
           break;
       case TelephonyManager.CALL_STATE_IDLE:
           LogUtil.e("TelephonyManager.CALL_STATE_IDLE");
           context.stopService(new Intent(context, RecorderService.class));
           break;
       }
   }

三：通话录音服务

public class RecorderService extends Service {
   public static final String INTENT_PATH = "path";
   /**
   */
   private String currentFile = "";
   /**
   *
   * @param incomingNumber
   */
   private MediaRecorder recorder;

   @Override
   public boolean onUnbind(Intent intent) {
       return super.onUnbind(intent);
   }

   @Override
   public void onCreate() {
       super.onCreate();

}

   @Override
   public int onStartCommand(Intent intent, int flags, int startId) {
       String phone = intent.getStringExtra(PhoneReceiver.INTENT_PHONE_STR);
       boolean isDial = intent.getBooleanExtra(
               PhoneReceiver.INTENT_STATE_BOOL, true);
       // 创建文件
       String dirPath = FileUtil.getBasePath(getApplicationContext());
       File ff = new File(dirPath);
       if (!ff.exists()) {
           ff.mkdirs();
       }
       currentFile = dirPath + File.separator + getFileName(phone, isDial);
       setMaxStreamVolume();
       iniRecord(1);
       return super.onStartCommand(intent, flags, startId);
   }

   /**
   * 设置最大的通话音量。
   */
   private void setMaxStreamVolume() {
       AudioManager mAudioManager = ((AudioManager) getSystemService(Context.AUDIO_SERVICE));
       int maxVolume = mAudioManager
               .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
       mAudioManager.setStreamVolume(AudioManager.STREAM_VOICE_CALL,
               maxVolume, 0);
       mAudioManager.setStreamVolume(AudioManager.STREAM_MUSIC, maxVolume, 0);
   }

   /**
   * 初始化录音
   */
   private void iniRecord(int type) {
       try {
           recorder = new MediaRecorder();
           if (type == 1) {
               recorder.setAudioSource(MediaRecorder.AudioSource.VOICE_CALL);// 通话双向录音
           } else if (type == 2) {
               recorder.setAudioSource(MediaRecorder.AudioSource.MIC);// 麦克风
           } else if (type == 3) {
               recorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);// 耳机录音
           } else if (type == 4) {
               recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
           } else if (type == 5) {
               recorder.setAudioSource(MediaRecorder.AudioSource.REMOTE_SUBMIX);
           }
           recorder.setOutputFormat(MediaRecorder.OutputFormat.AMR_NB);
           recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
           recorder.setMaxDuration(1000 * 60 * 60 * 24);
           recorder.setMaxFileSize(1024 * 1024 * 1024 * 1024);
           recorder.setOutputFile(currentFile);
           Thread.sleep(2000);
           recorder.prepare();
           recorder.start();
           Log.e("phoneNumber", "录音开始" + currentFile);
       } catch (Throwable e) {
           Log.e("phoneNumber", "录音error");
           e.printStackTrace();
           if (type <= 4) {
               iniRecord(type + 1);
           } else {
               iniRecord(1);
           }
       }
   }

   /**
   * 停止录音
   */
   private void stopRecording() {
       if (recorder != null) {
           try {
               recorder.stop();
               recorder.reset();
               recorder.release();
               recorder = null;
           } catch (Exception e) {
           }
           Intent i = new Intent(ListActivity.RECORDER_DATA);
           i.putExtra(INTENT_PATH, currentFile);
           getApplication().sendBroadcast(i);
       }
   }

   /**
   * 获取名称
   *
   * @param incomingNumber
   * @return
   */
   private String getFileName(String incomingNumber, boolean isDial) {
       Date date = new Date(System.currentTimeMillis());
       String name;
       if (isDial) {
           name = incomingNumber + "_" + DateUtil.format(date) + "_" + "1";
       } else {
           name = incomingNumber + "_" + DateUtil.format(date) + "_" + "2";
       }
       return name;
   }
