调用SoundPool Thead onClickEvent [英] Calling a SoundPool Thead onClickEvent

问题描述

我正在尝试在单击视图对象时播放SoundPool.

I'm trying to have a SoundPool play while a view object is being clicked.

我已经成功实现了它，但是发现点击的声音会滞后.

I have successfully implemented it but found out that the sound of the click will lag.

我一直在研究StackOverFlow和互联网上的解决方案，最好的解决方案似乎是将SoundPool放在单独的线程上.

I've been researching on StackOverFlow and on the internet for solutions and the best solution seems to be to have the SoundPool on a separate Thread.

我对整个Thread知识还很陌生，所以我现在真的不知道该怎么办.

I'm very new to the whole Thread thing and so I don't really know what to do at the moment.

我已按照此指南创建了SoundPool线程，但是，我不知道如何访问它，甚至不知道如何分配要播放的剪辑.

I have followed THIS guide on creating a SoundPool thread, however, I don't know how to access it, or even to assign the clips that I wished to play.

有人可以给我一个例子，说明在单击视图中的对象时如何调用SoundPool线程播放剪辑.

Can someone please give me an example of how I should call the SoundPool thread to play my clip while an object in the view is being clicked.

请在下面找到我的onClick代码:

Please find my onClick code below:

@Override
public boolean onTouch(View v, MotionEvent event) {
    int actionPerformed = event.getAction();

    switch(actionPerformed) {
        case MotionEvent.ACTION_DOWN: {
            if (Math.pow((event.getX() - a_Ball.getX()),2)
                + Math.pow((event.getY() - a_Ball.getY()), 2)
                <= Math.pow(a_Ball.getDiameter(),2)) {
                //pCheck = !pCheck;
                if (pauseBall == false) {
                    SoundPool soundPool = new SoundPool(1,AudioManager.STREAM_MUSIC,1);
                    clickSound = soundPool.load(MainActivity.this, R.raw.click, 1);
                    /*soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
                        public void onLoadComplete(SoundPool soundPool, int sampleId,int status) {
                            soundPool.play(clickSound,1.0f, 1.0f, 0, 0, 1.0f);
                            }
                    });*/


                    //Increase Ball Speed
                    sIncrease = true;
                }
            } else {
                if (pauseBall == false) {
                    //set minus health when not touch on ball
                    health--;
                    TextView txtHealth = (TextView)findViewById(R.id.health);
                    String tempHealth = txtHealth.getText().toString();
                    tempHealth =  getResources().getString(R.string.health) + String.valueOf(health);
                    txtHealth.setText(tempHealth);
                }
            }
            break;
        }
        default:
            return false;
    }
    return true;
}   //onTouch end

谢谢.

推荐答案

您不需要线程即可毫无延迟地发出声音.滞后来自声音文件的加载，请尝试创建SoundPool并提前加载声音(soundPool.load)(例如onCreate)，然后只需在onTouch方法中调用soundPool.play.

You don't need threads to make sounds without lag. The lag comes from the loading of the sound file, try create the SoundPool and load the sound (soundPool.load) in advance (e.g. onCreate), then just call soundPool.play in your onTouch method.
