推荐答案

首先，我假设你有一个查询的ContentProvider和使用游标的基本知识。如果你不，我建议你研究它这里

First, I assume you have basic knowledge of querying a ContentProvider and working with Cursors. If you dont, I suggest you research it here

一旦你如何使用ContentProvider的，查询URI MediaStore.Audio.Media.EXTERNAL_CONTENT_URI 的列音频的基本知识。 Media.DATA ，以及任何你需要的其他领域。

Once you have a basic knowledge of how to use a ContentProvider, query the URI MediaStore.Audio.Media.EXTERNAL_CONTENT_URI for the column Audio.Media.DATA, along with any other fields you need.

假设你把返回光标 yourCursor

String path = yourCursor.getString(getColumnIndex(Audio.Media.DATA));

MediaPlayer mp = new MediaPlayer();
mp.setDataSource(path);
mp.prepare();
mp.start();

这是一个非常基本实现。如果你需要得到看中它获得舒适与Android文档。

That's a very basic implementation. Get comfy with the android docs if you need to get fancy with it.
