问题描述

我已存储的MP3文件设定在我的SD卡。现在我想检索秒的持续时间。我通过几个环节去了，我使用 MediaMetadataRetriever 类是能够找到解决办法只能从SDK版本10。但我的要求是SDK版本7.有什么办法，找出MP3文件的时间。我很抱歉，如果这是一个重复的问题在这里。

I have stored set of MP3 files in my sd card. Now I want to retrieve its duration in seconds. I went through few links and I was able to find solution only from SDK version 10 using the MediaMetadataRetriever class. But my requirement is for SDk version 7. Is there any way to find out the duration of mp3 files. I am sorry if this is a repeated question here.

我知道，使用MediaPlayer的 getDuration（）解决了这个问题。但我不希望使用此。

I know that using MediaPlayer's getDuration() solves this issue. But I don't want to use this.

任何帮助很多AP preciated。

Any help is much appreciated.

推荐答案

你有足够的数据来查询EXTERNAL_CONTENT_URI？随着标题，比如，你可以做到以下几点：

Do you have enough data to query the EXTERNAL_CONTENT_URI? With the title, for instance, you could do the following:

Cursor cursor= getContentResolver().query(android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,null,android.provider.MediaStore.Audio.Media.TITLE+"=='Hallelujah'",null,null);
cursor.moveToFirst();
int duration=cursor.getInt(cursor.getColumnIndex(android.provider.MediaStore.Audio.Media.DURATION));
