我如何阅读与歌曲相关的流派？我可以读这首歌,但是如何抓住这首歌的流派,它存放在哪里？
谢谢！
解决方法
检查此代码：
public class MusicLibraryScanner {
private static Cursor mediaCursor;
private static Cursor genresCursor;
private static String[] mediaProjection = {
MediaStore.Audio.Media._ID,MediaStore.Audio.Media.ARTIST,MediaStore.Audio.Media.ALBUM,MediaStore.Audio.Media.TITLE
};
private static String[] genresProjection = {
MediaStore.Audio.Genres.NAME,MediaStore.Audio.Genres._ID
};
public static void getMusicFromStorage(Context context) {
mediaCursor = context.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI,mediaProjection,null,null);
int artist_column_index = mediaCursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.ARTIST);
int album_column_index = mediaCursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.ALBUM);
int title_column_index = mediaCursor
.getColumnIndexOrThrow(MediaStore.Audio.Media.TITLE);
int id_column_index = mediaCursor
.getColumnIndexOrThrow(MediaStore.Audio.Media._ID);
if (mediaCursor.movetoFirst()) {
do {
String info = "Song " + mediaCursor.getString(title_column_index) + " ";
info += "from album " + mediaCursor.getString(album_column_index) + " ";
info += "by " + mediaCursor.getString(artist_column_index) + ". ";
int musicId = Integer.parseInt(mediaCursor.getString(id_column_index));
Uri uri = MediaStore.Audio.Genres.getContentUriForAudioId("external",musicId);
genresCursor = context.getContentResolver().query(uri,genresProjection,null);
int genre_column_index = genresCursor.getColumnIndexOrThrow(MediaStore.Audio.Genres.NAME);
if (genresCursor.movetoFirst()) {
info += "Genres: ";
do {
info += genresCursor.getString(genre_column_index) + " ";
} while (genresCursor.movetoNext());
}
Log.e("Audio scanner","Song info: " + info);
} while (mediaCursor.movetoNext());
}
}
}
