试试这个方法就可以了

  public class DB_Parse extends Activity {

private static final String TAG = "MyActivity";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Log.v(TAG, "Initializing sounds...");

    final MediaPlayer mp = MediaPlayer.create(this, R.raw.youraudio);

    Button play_button = (Button)this.findViewById(R.id.play_button);
    play_button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            Log.v(TAG, "Playing sound...");
            mp.start();
        }
    });
    Log.v(TAG, "Sounds initialized.");
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}

}
