我正在使用 SoundPool 为我的 Android 应用程序播放声音。所有声音都在应用程序开始时加载,以防止应用程序本身出现任何滞后。只要未设置为循环播放,所有声音都可以正常播放。当我将循环设置为真(设置为-1)时,声音不会播放。
根据用户的输入,有 6 种不同的声音会停止和启动。它播放第一个声音很好,但随后的声音无法播放。
我已经尝试了各种方法,例如暂停而不是停止,将音量设置为 0 并将循环设置为 0 而不是暂停,将循环设置为任意大的数字而不是真正的重复,使声音更短,并且没有这些已经工作了。
我的代码如下:
public int loadSound(int soundFile)
{
int soundID;
try
{
if (m_loadedSounds.containsKey(soundFile))
{
soundID = m_loadedSounds.get(soundFile);
}
else
{
soundID = m_soundPool.load(m_context, soundFile, 1);
m_loadedSounds.put(soundFile, soundID);
}
}
catch (Exception e)
{
soundID = -1;
}
return soundID;
}
public void playSound(int soundFile, boolean loop)
{
// Grab it from the map
int soundID = loadSound(soundFile);
int loops = loop ? -1 : 0;
float streamVolume = m_audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
streamVolume /= m_audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC);
// If succeeded then play the sound
if (soundID != -1)
{
if (m_soundStreams.containsKey(soundID))
{
int streamID = m_soundStreams.get(soundID);
m_soundPool.setLoop(streamID, loops);
m_soundPool.resume(streamID);
}
else
{
int streamID = m_soundPool.play(soundID, streamVolume, streamVolume, 1, loops, 1.0f);
Log.d("SOUNDS", "Sound played! ID: " + soundID + " At volume: " + streamVolume + " Looping: " + (loop ? "Yes": "No") + " Success: " + (streamID != 0 ? "Yes" : "No"));
if (streamID != 0)
{
m_soundStreams.put(soundID, streamID);
}
}
}
}
public void stopSound(int soundFile)
{
int soundID = loadSound(soundFile);
Integer streamID = m_soundStreams.get(soundID);
if (streamID != null)
{
m_soundPool.pause(streamID);
}
}
LogCat 在运行时给出的错误是:

有人知道这个烦人的问题的任何解决方案,或者我没有尝试过的任何解决方法吗?
