SoundPool的使用以及登录密码

float j = 1.0f; 

SoundPoolsp=null;

intsID=0;

@Override

publicvoidonCreate(BundlesavedInstanceState){

super.onCreate(savedInstanceState);(R.layout.main);

Buttonb=(Button)findViewById(R.id.Button01);

b.setOnClickListener(newOnClickListener(){

@Override

publicvoidonClick(Viewv){

j=(float)(j+.5f);

sp.setRate(sID,j);

}

});

AssetFileDescriptorafd;

try{

sp=newSoundPool(1,AudioManager.STREAM_MUSIC,0);

afd=getAssets().openFd("wav/sample.wav");

intid=sp.load(afd,1);

sID=sp.play(id,1,1,1,0,j);

}catch(IOExceptione){

//TODOAuto-generatedcatchblock

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”
