Question

我使用下面的代码记录Android手机中的来电和去电通话此代码仅在麦克风或扬声器打开且用户禁用扬声器电话时才有效，我的代码将无法记录来电我想录制来电和去电通话，而无需激活电话扬声器。

    class MyPhoneStateListener extends PhoneStateListener implements SensorEventListener {
            Context context;
            AudioManager audioManager;
            MediaRecorder recorder;
            private SensorManager mSensorManager;
            private Sensor myLightSensor;
            private boolean CallState;
            private float sensorState;

            public MyPhoneStateListener(Context context) {
                this.context = context;
                mSensorManager = (SensorManager) this.context.getSystemService(Context.SENSOR_SERVICE);
                myLightSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_PROXIMITY);
                audioManager = (AudioManager) this.context.getSystemService(Context.AUDIO_SERVICE);
                if (myLightSensor == null){
                    Log.i("On Receive", "Not Support");
                }else{
                    mSensorManager.registerListener(this,myLightSensor,SensorManager.SENSOR_DELAY_NORMAL);
                }
            }

                    StartAudioSpeacker();

Answer 1

我想录制来电和去电通话而不激活手机扬声器。

很抱歉，但Android上一般不支持此功能。

Android接听拨出电话录音
