这是对我有用的简短示例：
public class Internal extends Activity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public void onPlayClicked(View v) { start(); } public void onStopClicked(View v) { stop(); } boolean m_stop = false; AudioTrack m_audioTrack; Thread m_noiseThread; Runnable m_noiseGenerator = new Runnable() { public void run() { Thread.currentThread().setPriority(Thread.MIN_PRIORITY); byte [] noiseData = new byte[1000]; Random rnd = new Random(); while(!m_stop) { rnd.nextBytes(noiseData); m_audioTrack.write(noiseData, 0, noiseData.length); } } }; void start() { m_stop = false; m_audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 8000, AudioFormat.CHANNEL_OUT_MONO, AudioFormat.ENCODING_PCM_8BIT, 8000 , AudioTrack.MODE_STREAM); m_audioTrack.play(); m_noiseThread = new Thread(m_noiseGenerator); m_noiseThread.start(); } void stop() { m_stop = true; m_audioTrack.stop(); } }
