我的OnCreate（）代码

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //Audio, mic to speaker
    setVolumeControlStream(AudioManager.STREAM_MUSIC);
    initControls();
    mAudioThread = new AudioThread();
    mAudioThread.start();

    //end

    //Equalizer
    enabled = (CheckBox)findViewById(R.id.enabled);
    enabled.setOnCheckedChangeListener (this);

    flat = (Button)findViewById(R.id.flat);
    flat.setOnClickListener(this);

    bass_boost = (SeekBar)findViewById(R.id.bass_boost);
    bass_boost.setOnSeekBarChangeListener(this);
    bass_boost_label = (TextView) findViewById (R.id.bass_boost_label);

    sliders[0] = (SeekBar)findViewById(R.id.slider_1);
    slider_labels[0] = (TextView)findViewById(R.id.slider_label_1);
    //more sliders till [4]

    mEqualizer = new Equalizer(0, mAudioTrack.getAudioSessionId());
    mEqualizer.setEnabled(true);

    eq = new Equalizer (0, 0);
    if (eq != null)
      {
      eq.setEnabled (true);
      int num_bands = eq.getNumberOfBands();
      num_sliders = num_bands;
      short r[] = eq.getBandLevelRange();
      min_level = r[0];
      max_level = r[1];
      for (int i = 0; i < num_sliders && i < MAX_SLIDERS; i++)

updateUI();
         }

对于我的AudioThread：

    public class AudioThread extends Thread {

    // Handler message constants
    public static final int PLAY = 0;
    public static final int STOP = 1;

    // Class variables
    private boolean mRunning = false;
    private boolean mPlayAudio = false;



    private static class AudioThreadHandler extends Handler {
        private final WeakReference<AudioThread> mThread;

        public AudioThreadHandler(AudioThread thread) {
            mThread = new WeakReference<AudioThread>(thread);
        }

        @Override
        public  void handleMessage(Message msg) {
            AudioThread thread = mThread.get();
            if (thread != null) {
                switch(msg.what) {
                case PLAY:
                    thread.mPlayAudio = true;
                    break;
                case STOP:
                    thread.mPlayAudio = false;
                    break;
                }
            }
        }
    };
    static final int bufferSize = 320000;
    final short[] buffer = new short[bufferSize];
    short[] readBuffer = new short[bufferSize];
    private final AudioThreadHandler mAudioThreadHandler = new AudioThreadHandler(this);


    @Override
    public void run() {
        try {
            int buffersize = AudioRecord.getMinBufferSize(11025, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT);
            AudioRecord arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 11025, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize);
            AudioTrack atrack = new AudioTrack(AudioManager.STREAM_MUSIC, 11025, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize, AudioTrack.MODE_STREAM);
            atrack.setPlaybackRate(11025);
            byte[] buffer = new byte[buffersize];
            arec.startRecording();
            atrack.play();
            mRunning = true;
            while(mRunning) { 
                if (mPlayAudio) {
                arec.read(buffer, 0, buffersize);
                atrack.write(buffer, 0, buffer.length);
                 }else {
                    }
                }

        } catch (Exception e) {
            Log.e("AudioThread", "Thread Loop Exception: " + e);
        }
    }

    public void close() {
        mRunning = false;
    }

    public Handler getHandler() {
        return mAudioThreadHandler;
    }
}

抱歉，一切似乎都很混乱。但是这个错误已经困扰了我很长时间了。希望你们真的能帮上忙。如果您愿意，请看一下我的项目，并向我提供有关我做错了事情的说明。
