android获取本地音乐的专辑图片

获取本地的音文件请查看 

获取专辑图片主要是通过album_id进行查询，因此首先获取album_id

String album_id = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));

Sdcard上的专辑图片存储位置为 /storage/emulated/0/Android/data/com.android.providers.media/albumthumbs/

接下来获取album_art

private String getAlbumArt(int album_id) {String mUriAlbums = "content://media/external/audio/albums";String[] projection = new String[] { "album_art" };Cursor cur = this.getContentResolver().query(Uri.parse(mUriAlbums + "/" + Integer.toString(album_id)),projection, null, null, null);String album_art = null;if (cur.getCount() > 0 && cur.getColumnCount() > 0) {cur.moveToNext();album_art = cur.getString(0);}cur.close();cur = null;
