SoundPool的使用以及登录密码

float j = 1.0f; 
SoundPool sp = null; 
int sID = 0; 
 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); (R.layout.main); 
 
    Button b = (Button)findViewById(R.id.Button01); 
    b.setOnClickListener(new OnClickListener() { 
 
        @Override 
        public void onClick(View v) { 
            j = (float) (j +.5f); 
            sp.setRate(sID,j); 
 
        } 
    }); 
 
    AssetFileDescriptor afd; 
    try { 
 
        sp = new SoundPool(1, AudioManager.STREAM_MUSIC, 0); 
 
        afd = getAssets().openFd("wav/sample.wav"); 
        int id = sp.load(afd, 1); 
        sID = sp.play(id, 1, 1, 1, 0, j); 
 
    } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
    } 
} 
为了改变 rate of play afterward 必须使用sp.setRate(StreamID,j)

    setContentView

而且“每一个pool最多1M”
