使用此代码播放音频。

mp = MediaPlayer.create(yourclassname.this, R.raw.mysound);
                        mp.setOnCompletionListener(new OnCompletionListener() {

                            @Override
                            public void onCompletion(MediaPlayer mp) {
                                // TODO Auto-generated method stub
                                mp.release();
                            }

                        });   
                        mp.start();
