如何在2个线程中使用麦克风？

Question

我正在使用语音识别创建应用程序并将其输出到TextView。 为了可视化此过程，我使用the example implementation。在出口处，我们大致可视化语音 -

实施如下：

 // The sampling rate for the audio recorder.
private static final int SAMPLING_RATE = 44100;

private WaveformView mWaveformView;
private TextView mDecibelView;

private RecordingThread mRecordingThread;
private int mBufferSize;
private short[] mAudioBuffer;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.layout_waveform);

    mWaveformView = (WaveformView) findViewById(R.id.waveform_view);

    // Compute the minimum required audio buffer size and allocate the buffer.
    mBufferSize = AudioRecord.getMinBufferSize(SAMPLING_RATE, AudioFormat.CHANNEL_IN_MONO,
            AudioFormat.ENCODING_PCM_16BIT);
    mAudioBuffer = new short[mBufferSize / 2];

}

@Override
protected void onResume() {
    super.onResume();

    mRecordingThread = new RecordingThread();
    mRecordingThread.start();
}

本身就是记录的背景线程：

/**
 * A background thread that receives audio from the microphone and sends it to the waveform
 * visualizing view.
 */
private class RecordingThread extends Thread {

    private boolean mShouldContinue = true;

    @Override
    public void run() {
        android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_AUDIO);

        AudioRecord record = new AudioRecord(AudioSource.MIC, SAMPLING_RATE,
                AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, mBufferSize);
        record.startRecording();

        while (shouldContinue()) {
            record.read(mAudioBuffer, 0, mBufferSize / 2);
            mWaveformView.updateAudioData(mAudioBuffer);
            updateDecibelLevel();
        }

        record.stop();
        record.release();
    }

    /**
     * Gets a value indicating whether the thread should continue running.
     *
     * @return true if the thread should continue running or false if it should stop
     */
    private synchronized boolean shouldContinue() {
        return mShouldContinue;
    }

    /** Notifies the thread that it should stop running at the next opportunity. */
    public synchronized void stopRunning() {
        mShouldContinue = false;
    }

语音识别的实现是标准方法，因此我认为这可能不会......

  

问题的实质

当我打开程序工作或可视化工具或识别而不是两者时，如何同时运行两者？
