Question

AVAudioPlayer 怎样获取当前音频文件的总播放时长

Answer 1

MediaPlayer md = new MediaPlayer();
try {
LogUtils.log(Environment.getExternalStorageDirectory() +"/123.mp3");
md.setDataSource(Environment.getExternalStorageDirectory() +"/123.mp3");
md.prepare();
LogUtils.log("size " + md.getDuration());
} catch (Exception e) {
e.printStackTrace();
}

MediaPlayer 初始化 -> setDataSource->prepare-> 就可以获取到了getDuration() 单位是ms
