How to play a Sound Effect in Android
提问by ThreaT
I'm looking to do a very simple piece of code that plays a sound effect. So far I have this code:
我正在寻找一段非常简单的代码来播放声音效果。到目前为止，我有这个代码：
SoundManager snd;
int combo;
private void soundSetup() {
// Create an instance of the sound manger
snd = new SoundManager(getApplicationContext());
// Set volume rocker mode to media volume
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
// Load the samples from res/raw
combo = snd.load(R.raw.combo);
}
private void playSound() {
soundSetup();
snd.play(combo);
}
However, for some reason when I use the playSound()method, nothing happens. The audio file is in the correct location.
但是，由于某种原因，当我使用该playSound()方法时，没有任何反应。音频文件位于正确的位置。

Is there a specific reason you are using SoundManager? I would use MediaPlayerinstead, here is a link to the Android Docs
您是否有特定的使用原因SoundManager？我会MediaPlayer改用，这里是 Android Docs 的链接
http://developer.android.com/reference/android/media/MediaPlayer.html
http://developer.android.com/reference/android/media/MediaPlayer.html
then it's as simple as
那么就这么简单
MediaPlayer mp = MediaPlayer.create(getApplicationContext(), R.raw.combo);
mp.start();
Make a directory called "raw/" under the "res/" directory. Drag wav or mp3 files into the raw/ directory. Play them from anywhere as above.
在“res/”目录下创建一个名为“raw/”的目录。将 wav 或 mp3 文件拖到 raw/ 目录中。从上面的任何地方播放它们。

i have also attempted using the top answer, yet it resulted in NullPointerExceptions from the MediaPlayer when i tried playing a sound many times in a row, so I extended the code a bit.
我也尝试使用最佳答案，但是当我尝试连续多次播放声音时，它导致 MediaPlayer 出现 NullPointerExceptions，因此我稍微扩展了代码。
FXPlayer is my global MediaPlayer.
FXPlayer 是我的全球 MediaPlayer。
public void playSound(int _id)
{
if(FXPlayer != null)
{
FXPlayer.stop();
FXPlayer.release();
}
FXPlayer = MediaPlayer.create(this, _id);
if(FXPlayer != null)
FXPlayer.start();
}
