音频播放优化

初始化MediaPlayer

private void initMediaPlayer() {
        mediaPlayer = new MediaPlayer();
        mediaPlayer.setOnCompletionListener(this);//设置播放完成监听
        mediaPlayer.setOnPreparedListener(this);//设置准备完成监听
        mediaPlayer.setOnBufferingUpdateListener(this);//设置音频缓冲监听
        btnAudio.setText("创建MediaPlayer");

        try {
            mediaPlayer.setDataSource("http://116.255.252.173:888/Images/MaxImages/201702/709b7c04-8f7c-4bd0-9142-7f84bfb184ac.mp3");//设置音频资源路径

            mediaPlayer.prepareAsync();//开始后台缓冲
            btnAudio.setText("设置音频资源,开启后台缓冲");
        } catch (IOException e) {
            Toast.makeText(this, "未找到音频资源", Toast.LENGTH_SHORT).show();
        }
    }

监听代码

 /**
     * Called when the end of a media source is reached during playback.
     *
     * @param mp
     */
    @Override
    public void onCompletion(MediaPlayer mp) {
        btnAudio.setText("onCompletion called");
        btnAudio.setEnabled(true);
    }

    //完成prepareAsync方法时
    @Override
    public void onPrepared(MediaPlayer mp) {
        btnAudio.setText("完成缓冲");
        btnAudio.setEnabled(true);
    }

    //正在缓冲...
    @Override
    public void onBufferingUpdate(MediaPlayer mp, int percent) {
        btnAudio.setText(percent + "%");
    }

开始播放音频调用mediaPlayer.start();

记得在适当的时候控制音频的播放。
