Android一次播放1个声音
问题描述：
再次问这个问题的道歉。我以为我发现我后来的信息，但公共无效停止（）似乎并没有工作。我正在使用Soundpool和SoundManger。我只需要一个声音就可以在任何时候播放。一旦按下另一个按钮，我希望所有以前的声音停止，并播放最近按下的按钮。Android一次播放1个声音
这里是我的SoundManger：
package com.androidbook.ufgsoundboard;
import java.util.HashMap;
import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;
public class SoundManager {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public static final int maxSounds = 1;
public SoundManager()
{
}
public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
}
public void addSound(int Index,int SoundID)
{
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
}
public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
}
这里是我的音板：
package com.androidbook.ufgsoundboard;
import com.androidbook.ufgsoundboard.SoundManager;
import android.app.Activity;
import android.content.Intent;

UFGcharactersActivity.class);
startActivityForResult(myIntent, 0);

Button next = (Button) findViewById(R.id.button2);
next.setOnClickListener(new View.OnClickListener() {

// fire intent
finish(); // finish current activity

startActivityForResult(myIntent, 0);
}
});}
};
我希望它的一个简单变化，我只是不能似乎找到或锻炼身体。
谢谢大家的期待。

在SoundManager你initSounds()方法，改变4到1：
mSoundPool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);
我碰到了同样的问题，一旦:)
好运

对于简单的应用程序，我使用这个静态声音类。
public class Sound
{
private static MediaPlayer mp = null;
/** Stop old sound and start new one */
public static void play(Context context, int resource)
{
stop(context);
mp = MediaPlayer.create(context, resource);
mp.setLooping(false);
mp.start();
}
/** Stop the music */
public static void stop(Context context)
{
if (mp != null)
{
mp.stop();
mp.release();
mp = null;
}
}
}

谢谢。只是为了测试目的需要一些哔声。你的小班帮助了我很多，只是放下它，毫无麻烦地工作，所以我可以专注于我的实际工作。不胜感激！ – Ridcully
来到后的尝试所有天我终于找到了答案！我目前有代码显示：mSoundPool = new mSoundPool = new SoundPool（4，AudioManager.STREAM_MUSIC，0）;我已将其更改为mSoundPool = new SoundPool（1，AudioManager.STREAM_MUSIC，0）;现在它只播放1个声音！ – PaulH
