Trying to implement a video gallery with horizontal scrollview children inside an expandablelistview.
Problem facing - Instead of showing all n number of children of the group in Horizontal list view, duplicate of the first child is created n times horizontally.
Here is my code
This activity fetches the videos saved in a particular folder (photography) in sd-card. Checks for videos inside subfolders(here crane,helicam,montage,multi) and put it in different categories in expandablelistview groups
public class ExpandableListActivity extends Activity {
List<String> groupList;
List<String> childList;
Map<String, List<String>> Collection;
ExpandableListView expListView;
ExpandableListAdapters expListAdapter;
public static final String DOC_FOLDER_NAME = "/photography/"; //FOLDER
public static final String DOC_FOLDER_NAME_ONE = "/Crane/";
public static final String DOC_FOLDER_NAME_TWO = "/Helicam/";
public static final String DOC_FOLDER_NAME_THREE = "/Montage/";
public static final String DOC_FOLDER_NAME_FOURE = "/Multi camera output/";
private static final String TAG="OM";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_layout);
this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
final String sdCard = Environment.getExternalStorageDirectory().toString() +DOC_FOLDER_NAME;
if(getDeviceFiles().size() > 0)
{
createCollection();
expListView = (ExpandableListView) findViewById(R.id.laptop_list);
final ExpandableListAdapters expListAdapter = new ExpandableListAdapters(this, Collection, groupList);
expListView.setAdapter(expListAdapter);
// setGroupIndicatorToRight();
expListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {

@Override

if (groupPosition != previousItem)
expListView.collapseGroup(previousItem);
