怎样在android中实现和java me中playTone一样的功能

[一口三个汉堡]

如题，就是在android实现可以自己设定他播放的音调，如音乐中do，rui，mi，fa，so，la，xi，dou。
搜了很久没看到，发现ToneGenerator有类似功能，但不能实现自定义相应的音调。

	    private final int    duration    = 1; // seconds
	    private final int    sampleRate  = 8000;
	    private final int    numSamples  = duration * sampleRate;
	    private final double sample[] = new double[numSamples];
	    private final double freqOfTone[] ={262, 294,330,349,392,440,494,524}; // do，rui，mi，fa，so，la，xi，dou的频率
	    private final byte   generatedSnd[] = new byte[2 * numSamples];
            private int          freqCnt=0;

  
  class PlayThread extends Thread
  {
    private int  playfreq;//播放频率 
	 public PlayThread(int cnt)
	 {
		playfreq=cnt%8;
	 }
	
	
	@Override
	public void run() {
		// TODO Auto-generated method stub

	      for (int i = 0; i < numSamples; ++i) {
	          sample[i] = Math.sin(2 * Math.PI * i / (sampleRate/freqOfTone[playfreq]));
	      }
	      int idx = 0;
	      for (final double dVal : sample) {
	          // scale to maximum amplitude
	          final short val = (short) ((dVal * 32767));
	          // in 16 bit wav PCM, first byte is the low order byte
	          generatedSnd[idx++] = (byte) (val & 0x00ff);
	          generatedSnd[idx++] = (byte) ((val & 0xff00) >>> 8);
	      }
	    
	    
	     final AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC,
	              sampleRate, AudioFormat.CHANNEL_CONFIGURATION_MONO,
	              AudioFormat.ENCODING_PCM_16BIT, numSamples,
	              AudioTrack.MODE_STATIC);
	     audioTrack.write(generatedSnd, 0, generatedSnd.length);
	     audioTrack.play();
		  super.run();
	}	  
  }  

调用

   new PlayThread(0).start();  //0播发duo  1播放rui 2播放mi ......

我试过了 可以
