播放短.wav文件 - 安卓 [英] Playing short .wav files - Android

问题描述

我想触摸按钮后，播放的声音。 MediaPlayer的工作正常，但我读的地方，这个库是长期.WAV（如音乐）。

I would like to play sound after touching the button. MediaPlayer works fine, but I read somewhere that this library is for long .wav (like music).

有没有更好的方式来播放.WAV短（2-3秒）？

Is there any better way to play short .wav(2-3 sec.)?

推荐答案

在的Soundpool 是正确的类此。下面code是如何使用它的示例。这也是code我用我的几个应用程序来管理的声音。你可以在5月的声音，只要你喜欢（或内存许可证）。

The SoundPool is the correct class for this. The below code is an example of how to use it. It is also the code I use in several apps of mine to manage the sounds. You can have as may sounds as you like (or as memory permits).

public class SoundPoolPlayer {
    private SoundPool mShortPlayer= null;
    private HashMap mSounds = new HashMap();

    public SoundPoolPlayer(Context pContext)
    {
        // setup Soundpool
        this.mShortPlayer = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);


        mSounds.put(R.raw.<sound_1_name>, this.mShortPlayer.load(pContext, R.raw.<sound_1_name>, 1));
        mSounds.put(R.raw.<sound_2_name>, this.mShortPlayer.load(pContext, R.raw.<sound_2_name>, 1));
    }

    public void playShortResource(int piResource) {
        int iSoundId = (Integer) mSounds.get(piResource);
        this.mShortPlayer.play(iSoundId, 0.99f, 0.99f, 0, 0, 1);
    }

    // Cleanup
    public void release() {
        // Cleanup
        this.mShortPlayer.release();
        this.mShortPlayer = null;
    }
}

您可以使用此调用：

SoundPoolPlayer sound = new SoundPoolPlayer(this); 

在活动的onCreate（）（或之后任何时候的话）。在这之后，播放声音简单的调用：

in your Activity's onCreate() (or anytime after it). After that, to play a sound simple call:

sound.playShortResource(R.raw.<sound_name>);

最后，一旦你的声音做了，叫：

Finally, once you're done with the sounds, call:

sound.release();

要释放资源。
