当我在片段onCreateView，onStart或onResume应用程序中调用它时，SoundPool的问题会变慢。
当我按下按钮尝试获取ID时，声音不会出现Logcat写的“SoundPool：sample 1 not READY”
请帮帮我，有什么想法吗？谢谢！

当方法被称为Sound.loadSound（...，...）时单击声音不起作用，并且Logcat写入“SoundPool：sample 1 not READY”
switch (v.getId()) {
case R.id.imageButtonAlligator:
mAlligatorSound = Sound.loadSound(getContext(),"alligator.wav");
Sound.playSound(mAlligatorSound);
Toast.makeText(view.getContext(),R.string.Alligator, Toast.LENGTH_SHORT).show();
break;
case R.id.imageButtonBat:
mBatSound = Sound.loadSound(getContext(), "bat.mp3");
Sound.playSound(mBatSound);
Toast.makeText(view.getContext(),R.string.Bat, Toast.LENGTH_SHORT).show();
break;
case R.id.imageButtonBear:
mBearSound = Sound.loadSound(getContext(),"bear.wav");
Sound.playSound(mBearSound);
Toast.makeText(view.getContext(),R.string.Bear, Toast.LENGTH_SHORT).show();
break;
case R.id.imageButtonBobCat:
mBobcatSound=Sound.loadSound(getContext(),"bobcat.mp3");
Sound.playSound(mBobcatSound);
Toast.makeText(view.getContext(),R.string.BobCat, Toast.LENGTH_SHORT).show();
break;
case R.id.imageButtonCat:
mCatSound= Sound.loadSound(getContext(),"cat.wav");
Sound.playSound(mCatSound);
Toast.makeText(view.getContext(),R.string.Cat, Toast.LENGTH_SHORT).show();
break;
这是静态方法声音
public class Sound {
public static SoundPool mSoundPool;
public static AssetManager mAssetManager;
public static int mStreamID;
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
public static void createNewSoundPool() {
AudioAttributes attributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_GAME)
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.build();
mSoundPool = new SoundPool.Builder()
.setAudioAttributes(attributes)
.build();
}
@SuppressWarnings("deprecation")
public static void createOldSoundPool() {
mSoundPool = new SoundPool(3, AudioManager.STREAM_MUSIC, 0);
}
public static int playSound(int sound) {
if (sound > 0) {
mStreamID = mSoundPool.play(sound, 1, 1, 1, 0, 1);
}
return mStreamID;
}
public static int loadSound(Context context , String fileName) {
mAssetManager = context.getAssets();
AssetFileDescriptor afd;
try {
afd = mAssetManager.openFd(fileName);
} catch (IOException e) {
e.printStackTrace();
Toast.makeText(context, "Не могу загрузить файл " + fileName,
Toast.LENGTH_SHORT).show();
return -1;
}
return mSoundPool.load(afd, 1);
}
}
答案 0 :(得分：1)
在对soundpool做任何事情之前，在实例化它之后，你需要设置一个监听器来知道它何时准备好使用，将声音加载到内存需要时间：这样做：
boolean loaded = false;//class variable
//in onCreate:
soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
@Override
public void onLoadComplete(SoundPool soundPool, int sampleId,
int status) {
loaded = true;
}
});
然后在使用soundPool之前，您需要检查Loaded是否为真 例如：
if (loaded) {
soundPool.play(soundID, volume, volume, 1, 0, 1f);
Log.e("Test", "Played sound");
}
