我发现使用audioTrack.setNotificationMarkerPosition(audioLength)和audioTrack.setPlaybackPositionUpdateListener对我有用.请参阅以下代码：

// Get the length of the audio stored in the file (16 bit so 2 bytes per short)

// and create a short array to store the recorded audio.

int audioLength = (int) (pcmFile.length() / 2);

short[] audioData = new short[audioLength];

DataInputStream dis = null;

try {

// Create a DataInputStream to read the audio data back from the saved file.

InputStream is = new FileInputStream(pcmFile);

BufferedInputStream bis = new BufferedInputStream(is);

dis = new DataInputStream(bis);

// Read the file into the music array.

int i = 0;

while (dis.available() > 0) {

audioData[i] = dis.readShort();

i++;

}

// Create a new AudioTrack using the same parameters as the AudioRecord.

audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, RECORDER_SAMPLE_RATE, RECORDER_CHANNEL_OUT,

RECORDER_AUDIO_ENCODING, audioLength, AudioTrack.MODE_STREAM);

audioTrack.setNotificationMarkerPosition(audioLength);

audioTrack.setPlaybackPositionUpdateListener(new OnPlaybackPositionUpdateListener() {

@Override

public void onPeriodicNotification(AudioTrack track) {

// nothing to do

}

@Override

public void onMarkerReached(AudioTrack track) {

Log.d(LOG_TAG, "Audio track end of file reached...");

messageHandler.sendMessage(messageHandler.obtainMessage(PLAYBACK_END_REACHED));

}

});

// Start playback

audioTrack.play();

// Write the music buffer to the AudioTrack object

audioTrack.write(audioData, 0, audioLength);

} catch (Exception e) {

Log.e(LOG_TAG, "Error playing audio.", e);

} finally {

if (dis != null) {

try {

dis.close();

} catch (IOException e) {

// don't care

}

}

}
