AudioTrack Android从原始文件夹播放声音

Question

是否可以播放原始资源文件夹中的AudioTrack的wav文件？它尝试了很多方法来引用我的Android项目中的原始文件，但我有很多例外。

这是我现在拥有的，但是当我按下按钮时，没有声音播放。

public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    Button buttonPlayAudioTrack = (Button) findViewById(R.id.buttonPlayAudioTrack); 
    buttonPlayAudioTrack.setOnClickListener(this); 

    int minBufferSize = AudioTrack.getMinBufferSize(44100, AudioFormat.CHANNEL_CONFIGURATION_MONO, 
         AudioFormat.ENCODING_PCM_16BIT); 

    audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 44100, AudioFormat.CHANNEL_CONFIGURATION_MONO, 
        AudioFormat.ENCODING_PCM_16BIT, minBufferSize, AudioTrack.MODE_STREAM); 
} 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    if(v.getId() == R.id.buttonPlayAudioTrack) 
     playSound(); 
} 

private void playSound() { 
    audioTrack.play(); 
    int i = 0; 
    int bufferSize = 512; 
    byte [] buffer = new byte[bufferSize]; 
    InputStream inputStream = getResources().openRawResource(R.raw.piano12); 
    try { 
     while((i = inputStream.read()) != -1) 
      audioTrack.write(buffer, 0, i); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    try { 
     inputStream.close(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
}

一切都很好，你的代码，你只需要改变

while((i = inputStream.read()) != -1) 

到

while((i = inputStream.read(buffer)) != -1)
