我有一个Soundpool,一旦查看动画开始,它就会播放短声音效果。问题在于,它只会第一次播放声音,而不会连续播放。
我已经检查了sound.play函数的返回结果,它始终是streamID,并且永远不会为零。它在需要时创建流,但是声音只是第一次播放。声音仅加载一次,因此自首次播放以来就不会成为加载问题。我将粘贴以下代码:
我正在调用createSoundPool()来构建声音池
private void createSoundPool() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
createNewSoundPool();
} else {
createOldSoundPool();
}
}
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void createNewSoundPool(){
AudioAttributes attributes = new AudioAttributes.Builder()
.setUsage(AudioAttributes.USAGE_GAME)
.setContentType(AudioAttributes.CONTENT_TYPE_MUSIC)
.build();
sounds = new SoundPool.Builder().setMaxStreams(5)
.setAudioAttributes(attributes)
.build();
}
@SuppressWarnings("deprecation")
private void createOldSoundPool(){
sounds = new SoundPool(5, AudioManager.STREAM_MUSIC,0);
}
这就是我的使用方式
public MyTouchListener(final Context context, final RecyclerView recyclerView,
OnTouchActionListener onTouchActionListener){
mOnTouchActionListener = onTouchActionListener;
initAnim();
createSoundPool();
drawCardSound = sounds.load(context,R.raw.drawcard,1); //this is where the soundID is created. Only once the class is instantiated
mGestureDetector = new GestureDetectorCompat(context,new GestureDetector.SimpleOnGestureListener(){
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2,
float velocityX, float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) {
return false;
}
// Find the item view that was swiped based on the coordinates
final View child = recyclerView.findChildViewUnder(e1.getX(), e1.getY());
final int childPosition = recyclerView.getChildAdapterPosition(child);
// right to left swipe
if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
if (mOnTouchActionListener != null && child != null) {
if(!animation.hasStarted() || animation.hasEnded()) {
child.startAnimation(animation);
animation.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
int res=sounds.play(drawCardSound,3,3,1,0,1f);// sound is being played here
Log.e("test", "onAnimationStart: "+res );
}
LogCat显示递增的streamID,并且永远不会为零,因此我认为它应该正确触发。
更新: 这个问题仅发生在Lollipop上,而我已经在下面的Lollipop模拟器上对其进行了测试,并且声音工作正常。棒棒糖及更高版本上是否存在一些错误?我已经在三星S7上对其进行了测试
答案 0 :(得分:4)
发现了问题!因此,显然SoundPool.Play()的左右音量不能取大于1.0的值。对于低于Lollipop的API来说这很好用,但是对于大于Lollipop的API来说效果不佳。我将值降低到1.0,现在可以正常使用了
