android - 从 MediaStore 过滤 mp3 文件

Question

我正在使用此代码从设备获取所有音频文件。

ContentResolver musicResolver = getContentResolver();
Uri musicUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
Cursor musicCursor = contentResolver.query(musicUri, null, null, null, null);

我只想获取 .mp3 文件，我们如何过滤查询的输出以仅获取 .mp3 文件

How to show only mp3 file using MediaStore?

ContentResolver cr = context.getContentResolver();

Uri uri = MediaStore.Files.getContentUri("external");

String[] projection = null;

String sortOrder = null;

String selectionMimeType = MediaStore.Files.FileColumns.MIME_TYPE + "=?";

String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("mp3"); 

String[] selectionArgsMp3 = new String[]{ mimeType };

Cursor allmp3Files = cr.query(uri, projection, selectionMimeType, selectionArgsmp3, sortOrder);
