android - Video gallery with expandablelistview parent horizontal scrollview child -
trying implement video gallery horizontal scrollview children inside expandablelistview.
problem facing - instead of showing n number of children of group in horizontal list view, duplicate of first child created n times horizontally.
here code
this activity fetches videos saved in particular folder (photography) in sd-card. checks videos inside subfolders(here crane,helicam,montage,multi) , put in different categories in expandablelistview groups
