Android Soundpool - 循环播放异常
我在使用 SoundPool 和 .OGG 文件播放循环声音时遇到问题。我设置了这个 HashMap，用于查找与名称关联的声音并播放/停止它。
public void playLoopSound(String soundName){
currentSound = (Integer) soundMap.get(soundName);
if(currentSound != -1){
try{
Logger.log("Playing Loop Sound: " + currentSound);
loopingSound = soundPool.play(currentSound, 1, 1, 0, -1, 1);
} catch (Exception e) {
Logger.log("Sound Playing Error: " + e.getMessage());
}
} else {
Logger.log("Sound Not Found");
}
}
public void stopLoopSound(){
soundPool.stop(loopingSound);
loopingSound = 0;
}
这个设置工作正常，我在角色开始行走时启动循环，并在角色停止行走时停止循环。
然而，声音会随机停止播放，通常是在使用（打开和关闭）后一分钟左右......
还有其他人遇到过 SoundPool 和循环声音的类似问题吗？
I am encountering problems with playing looping sounds using SoundPool and .OGG files. I have this HashMap set up for finding a sound associated to a name and playing it/stopping it
public void playLoopSound(String soundName){
currentSound = (Integer) soundMap.get(soundName);
if(currentSound != -1){
try{
Logger.log("Playing Loop Sound: " + currentSound);
loopingSound = soundPool.play(currentSound, 1, 1, 0, -1, 1);
} catch (Exception e) {
Logger.log("Sound Playing Error: " + e.getMessage());
}
} else {
Logger.log("Sound Not Found");
}
}
public void stopLoopSound(){
soundPool.stop(loopingSound);
loopingSound = 0;
}
This set up works fine, i start the loop when the character starts walking and stop it when it stops walking.
The sound would however stop playing randomly, usually a minute or so after having been used (being turned on and off)...
Has anyone else encountered similar problems with SoundPool and looped sounds?

阅读 Soundpool 上的文档可以清楚很多：
- 播放声音时，您传递一个引用加载声音的 int 。此方法（以及其他开始播放声音的方法） soundpool.play(int) 返回一个 int 值，引用当前播放声音的 threadID。
-当你想停止声音（或循环声音）时，你必须使用你开始播放声音时刚刚返回的threadID的int，而不是声音本身的int！
然后，在 soundpool 类中，设置一个 private int threadIDInt = mSoundPool.play/setloop/whatever(int soundtobeplayed, int/floatvolumeleft, int/floatvolumeright, float speed, int Loopornot); [注：论点有点编造；查找它们]
然后要停止声音（或暂停，或将其设置为循环或不循环），您可以传递 mSoundPool.stop(threadIDINT);
TLDR：表示您的声音的 int 和用于表示当前播放声音的流的内部 int soundpool 之间存在差异。
Reading the documentation on Soundpool clears up a lot:
-playing a sound you pass an int referring to the loaded sound. This method (and others starting a sound playing), soundpool.play(int) returns an int referring to the threadID in which the sound now plays.
-when you want to stop the sound (or the looping sound) you have to use the int of the threadID you just got back when you started playing the sound, NOT the int of the sound itself!
Within the soundpool class then, you set a private int threadIDInt = mSoundPool.play/setloop/whatever(int soundtobeplayed, int/float volumeleft, int/float volumeright, float speed, int loopornot); [note: the arguments are a bit made up; look 'em up]
To then stop the sound (or pause, or set it to loop or not) you pass mSoundPool.stop(threadIDINT);
TLDR: there's a differnce between the int which denotes your sound and the internal int soundpool uses to denote the stream in which your current sound is playing.
