小编use*_*257的帖子

我想将我的图像设置为音频mp3文件的专辑封面.我知道相册id,当我更新时,应用程序抛出java.lang.UnsupportedOperationException.

这是我的更新代码..

ContentValues values_art=new ContentValues();

values_art.put(MediaStore.Audio.AlbumColumns.ALBUM_ART, img_path);

int b=getContentResolver().update(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, values_art,MediaStore.Audio.Albums.ALBUM_ID + "=?", new String[]{album_id});

if(b !=0){
    Toast.makeText(getApplicationContext(), "Successfuly Image Updated", Toast.LENGTH_LONG).show();
}
else{
    Toast.makeText(getApplicationContext(), "Not Image Updated", Toast.LENGTH_LONG).show();
}
