Ok, here is a simple workflow:

1. Use FTPClient from org.apache.commons.net.ftp package to download file from FTP. The example snippet can be found here
2. Once you've got input stream, use BitmapFactory.decodeStream to convert it to a Bitmap
3. After that you can use setImageBitmap method to set the source for the ImageView.
4. Since ScrollView can have only one children, you can have a following layout structure, for example: ScrollView -> vertical LinearLayout with id = container.
5. Add all the needed ImageViews to container by calling addView method.
