好吧,我有一个带声音的ListView。当我点击其中一个时,它开始播放那首歌,但是当我点击其他一个/它时,它仍在播放。我想要做的是当我按下另一个时停止那个声音。我谷歌它,在这里找到完全相同的问题解决方案,但它不适合我。我得到错误,其中说:“MediaPlayer类型中的方法setDataSource(String)不适用于参数(int)”。我只是不知道如何获得具体位置,点击了哪个项目行。这就是我现在在onListItemClick()方法中所拥有的:

@Override
    public void onListItemClick(ListView parent, View v, int position, long id) {
        Minions s = (Minions) mSounds.get(position);
        MediaPlayer mPlayer;

        final boolean isPlaying = false;

        if(!isPlaying){
            mPlayer = new MediaPlayer();
            mPlayer.setDataSource(s.getSoundResourceId());
            mPlayer.prepare();
            mPlayer.start();
            isPlaying = true; 

        }else{

            isPlaying = false;
            mPlayer.stop();
            mPlayer.reset();
            mPlayer.setDataSource(s.getSoundResourceId());
            mPlayer.prepare();
            mPlayer.start();
            isPlaying = true;

        }

        mPlayer.setOnCompletionListener(new OnCompletionListener() {

            public void onCompletion(MediaPlayer mPlayer) {
                mPlayer.release();
                isPlaying = false;
            }

        });

    }

在我的情况下,我会这样做:

代替:

        mediaPlayer= new MediaPlayer();
         mediaPlayer.setDataSource(s.getSoundResourceId()); 

使用:

 mediaPlayer=MediaPlayer.create(context,R.raw.blabla);

这里您不需要prepare

private  MediaPlayer mPlayer;

....

@Override
public void onListItemClick(ListView parent, View v, int position, long id) {


    final boolean isPlaying = false;

    if(!isPlaying){
        mediaPlayer=MediaPlayer.create(context,R.raw.blabla);

        mPlayer.start();
        isPlaying = true; 

    }else{

        isPlaying = false;
        mPlayer.stop();
        mPlayer.reset();
        mediaPlayer=MediaPlayer.create(context,R.raw.blabla);           
        mPlayer.start();
        isPlaying = true;            

    }

    mPlayer.setOnCompletionListener(new OnCompletionListener() {

        public void onCompletion(MediaPlayer mPlayer) {
            mPlayer.release();
            isPlaying = false;
        }

    });

}

尝试setDataSource(""+s.getSoundResourceId());

而不是setDataSource(s.getSoundResourceId());

PS。也会初始化mPlayer

喜欢MediaPlayer mPlayer=new MediaPlayer();而不是MediaPlayer mPlayer;

并从if条件中删除此mPlayer = new MediaPlayer();
