推荐答案

我正在对我的应用

I'm doing something similar with my app Beat Shaker and I was having the same problem. I solved it using the onLoadCompleteListener:

// Sound pool new instance
SoundPool spool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
// Sound pool on load complete listener
spool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
    @Override
    public void onLoadComplete(SoundPool soundPool, int sampleId,
                        int status) {
        Log.i("OnLoadCompleteListener","Sound "+sampleId+" loaded.");
        boolean loaded = true;
    }
});       
// Load the sample IDs
int soundId = new int[3];
soundId[0] = spool.load(this, R.raw.sound1, 1);
soundId[1] = spool.load(this, R.raw.sound2, 1);
soundId[2] = spool.load(this, R.raw.sound3, 1);

稍后，在播放声音之前，您可以使用布尔值"loaded"检查声音是否正确加载.

Later before playing the sound you can check if it is properly loaded using the boolean "loaded".
