如何在Java Android的onLocationChanged中播放MediaPlayer一次？

MediaPlayer mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource("音频文件路径");

mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mp) {
        mediaPlayer.release();
    }
});

mediaPlayer.prepare();

mediaPlayer.start();

@Override
public void onLocationChanged(Location location) {
    // 创建MediaPlayer对象
    MediaPlayer mediaPlayer = new MediaPlayer();
    try {
        // 设置要播放的音频文件路径
        mediaPlayer.setDataSource("音频文件路径");
        // 设置音频播放完成后的监听器
        mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            @Override
            public void onCompletion(MediaPlayer mp) {
                mediaPlayer.release();
            }
        });
        // 准备MediaPlayer对象
        mediaPlayer.prepare();
        // 开始播放音频
        mediaPlayer.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
