如何用AudioTrack循环播放音频？

int streamType = AudioManager.STREAM_MUSIC;
int sampleRateInHz = 44100;
int channelConfig = AudioFormat.CHANNEL_OUT_MONO;
int audioFormat = AudioFormat.ENCODING_PCM_16BIT;
int bufferSizeInBytes = AudioTrack.getMinBufferSize(sampleRateInHz, channelConfig, audioFormat);
AudioTrack audioTrack = new AudioTrack(streamType, sampleRateInHz, channelConfig, audioFormat, bufferSizeInBytes, AudioTrack.MODE_STREAM);

byte[] audioData = // 从音频文件或其他来源获取音频数据
audioTrack.write(audioData, 0, audioData.length);

audioTrack.setLoopPoints(0, audioData.length / 2, -1);

audioTrack.play();

audioTrack.stop();
