封面上的android [英] cover art on android

问题描述

我为Android开发一种媒体播放器。现在的问题是我怎样才能在Android上的音频文件的封面。 例如，默认的Andr​​oid媒体播放器显示专辑上市的时候，我怎么能得到这个作品专辑封面。

解决方案

 乌里sArtworkUri = Uri.parse（内容：//媒体/外部/音频/ albumart）;
开放的我们的uri = ContentUris.withAppendedId（sArtworkUri，album_id）;
ContentResolver的解析度= context.getContentResolver（）;
InputStream的时间= res.openInputStream（URI）;
位图稿= BitmapFactory.de codeStream（中）;

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
Uri uri = ContentUris.withAppendedId(sArtworkUri, album_id);
ContentResolver res = context.getContentResolver();
InputStream in = res.openInputStream(uri);
Bitmap artwork = BitmapFactory.decodeStream(in);
