您可以使用 MediaMetaDataRetriever class从媒体文件中获取所有元数据 .
代码如下：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getInit();
// Ablum_art retrieval code //
metaRetriver = new MediaMetadataRetriever();
metaRetriver.setDataSource("/sdcard/audio.mp3");
try {
art = metaRetriver.getEmbeddedPicture();
Bitmap songImage = BitmapFactory
.decodeByteArray(art, 0, art.length);
album_art.setImageBitmap(songImage);
album.setText(metaRetriver
.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ALBUM));
artist.setText(metaRetriver
.extractMetadata(MediaMetadataRetriever.METADATA_KEY_ARTIST));
genre.setText(metaRetriver
.extractMetadata(MediaMetadataRetriever.METADATA_KEY_GENRE));
} catch (Exception e) {
album_art.setBackgroundColor(Color.GRAY);
album.setText("Unknown Album");
artist.setText("Unknown Artist");
genre.setText("Unknown Genre");
}
}
// Fetch Id's form xml
public void getInit() {
album_art = (ImageView) findViewById(R.id.album_art);
album = (TextView) findViewById(R.id.Album);
artist = (TextView) findViewById(R.id.artist_name);
genre = (TextView) findViewById(R.id.genre);
}
}
