使用MediaPlayer.isPlaying()和MediaPlayer.stop()方法。

public void stopPlaying()
{
    if(pikachuplayer != null && pikachuplayer.isPlaying())
    {
            pikachuplayer.stop();
    }
    if(digletplayer != null && digletplayer.isPlaying())
    {
            digletplayer.stop();
    }
    if(psyduckplayer != null && psyduckplayer.isPlaying())
    {
            psyduckplayer.stop();
    }
}

View.OnClickListener psyducklistner = new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        stopPlaying();
        psyduckplayer.start();

    }
};

View.OnClickListener pikachulistner = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        stopPlaying();
        pikachuplayer.start();

    }
};

View.OnClickListener digletlistner = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        stopPlaying();
        diglettplayer.start();
    }
};

View.OnClickListener digletlistner = new View.OnClickListener() {
    @Override
    public void onClick(View v) {

        diglettplayer.start();
    }
};

stopPlaying()方法停止播放所有媒体，只有当它们正在播放而不是null时（它们可能不是null，因为它们是成员变量，但它是仍然是一个很好的做法）。
