I have a ExpandableListView in a Fragment.
I'm posting a request to the server using RoboSpice onCreateView.
I want to be able to update the list twice, once when I get the data from the cache and second after the response returns.
For some reason the list is not populated.
I was able to populate it when I instantiate a new adapter and set the adapter for list, but for some reason it doesn't work on some android devices.
This is the code I'm using:
Fragment
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
_expandableListAdapter = new GroupsExpandableListAdapter(getActivity(), getSpiceManager());
_groupListView.setAdapter(_expandableListAdapter);
DBServerHelper.Groups.getByBusinessId(getActivity(), getSpiceManager(), getDBHelper(), _clientBusiness.getId(),
new CachedRequestListener<ClientGroup.List>(getDBHelper(), getActivity()) {
#Override
// This method runs twice, after the data comes from the cache and once the request succeed
public void onRequestFromCache(ClientGroup.List clientGroups) {
if (clientGroups == null || clientGroups.isEmpty()) {
Ln.d("Received clientGroups " + clientGroups == null ? "null" : "empty" + " form request GetByBusinessId");
return;
}
_expandableListAdapter.clear();
_expandableListAdapter.setGroups(clientGroups);
_expandableListAdapter.notifyDataSetChanged();
_groupListView.invalidateViews();
}
#Override
public void onRequestFailure(SpiceException spiceException) {
super.onRequestFailure(spiceException);
Ln.e(spiceException, "Failed to get groups ");
Toaster.showLong(getActivity(), "Could not get businesses groups: " + spiceException.getMessage());
}
});
}
GroupsExpandableListAdapter
public class GroupsExpandableListAdapter extends BaseExpandableListAdapter {
private ClientGroup.List _data;
private Activity _activity;
/**
* It is only possible to create a group using the factory method create below
* #param activity
*/
public GroupsExpandableListAdapter(Activity activity, SpiceManager manager) {
super();
_data = new ClientGroup.List();
_activity = activity;
_manager = manager;
}
#Override

}
public void clear() {

}
public void setGroups(ClientGroup.List groups) {

}

((ImageView) v.findViewById(R.id.groupIndicator))
.setImageResource(isExpanded ? R.drawable.arrow_up_turquoise : R.drawable.arrow_down_white);
} else {
v = convertView;
}
return v;
}
#Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
View v;
if (convertView == null) {
LayoutInflater li = (LayoutInflater) _activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = li.inflate(R.layout.group_list_child, parent, false);
} else {
v = convertView;
}
TextView joinGroupButton = (TextView) v.findViewById(R.id.joinGroupButton);
final ClientGroup group = _data.get(groupPosition);
String leaveGroupStr = _activity.getString(R.string.leave_group);
String joinGroupStr = _activity.getString(R.string.join_group);
return v;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return false;
}
}
Any suggestions?
Thanks!

I have a display problem with my 4-stage expandableList.
I can display my data, expand them but the last child does not display the whole list. How would you do it?
Here is a picture and the part of the code in question, I think it comes from the fact that I declare the size of the last list.

level 1-2 and 3 work fine and i can scroll
level 4 is not displayed completely and I can't scroll
Thank you for your help
I have a problem with my ExpendableList. I am trying
to make a 3 level expandablelist. The display on the 3 levels works
fine and stays tidy as it should. But I don't know why, the
subcategories are duplicated. Here is the whole code with the adapter
and the creation of my HashMap. If you have an idea where this comes
from you would help me a lot!

I've designed a GUI with an ExpandableListView, please see sample picture below.
I want to know if it is possible to get the IDs of all the child in the list without having to depend on the parent group.
Presently what I'm able to get is 0-2 for the first Parent and the second parent also starts from 0.
So basically I want to get the IDs like:
Fixture ? id(0)
Chillers ? id(1)
Displays ? id(2)
"33" Export (Can) id(3)
etc.
Here my Custom adapter class:
public class MTOExpandableListAdapter extends BaseExpandableListAdapter {
private Context _context;
private List<String> _listDataHeader; // header titles
// child data in format of header title, child title
private HashMap<String, List<String>> _listDataChild;
public MTOExpandableListAdapter(Context context, List<String> listDataHeader, HashMap<String, List<String>> listChildData) {
this._context = context;
this._listDataHeader = listDataHeader;
this._listDataChild = listChildData;
}
#Override
public int getGroupCount() {
return this._listDataHeader.size();
}
#Override
public int getChildrenCount(int groupPosition) {
return this._listDataChild.get(this._listDataHeader.get(groupPosition)).size();
}
#Override
public Object getGroup(int groupPosition) {
return this._listDataHeader.get(groupPosition);
}
#Override
public Object getChild(int groupPosition, int childPosition) {
return this._listDataChild.get(this._listDataHeader.get(groupPosition)).get(childPosition);
}
#Override
public long getGroupId(int childPosition) {
return childPosition;
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public boolean hasStableIds() {
return false;
}
#Override

String headerTitle = (String) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.list_mto_group, null);
}
TextView lblListHeader = (TextView) convertView.findViewById(R.id.lblListHeader);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(headerTitle);
return convertView;
}
#Override

final String childText = (String) getChild(groupPosition, childPosition);
if (convertView == null) {

convertView = inflater.inflate(R.layout.list_mto_item, null);
}
TextView txtListChild = (TextView) convertView.findViewById(R.id.lblMTOListItem);
txtListChild.setText(childText);
return convertView;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}

Okay, I see what you are asking. You are trying to get a unique ID for every child of every group, in numerical order.
#Override
public long getChildId(int groupPosition, int childPosition) {
int id = 0;
for (int group = 0; group < groupPosition; group++) {
id += getChildrenCount(group);
}
id += childPosition;
return id;
}
I have implemented a Expandable List View,in Android , you can see in the screenshot , it is working fine , and in Expandable List i have multiple child with delete option in group as you can see in the screen shot, i want to delete a particular child which user has selected to delete , I am not able to delete the child form Expandable List , i will post my code , please anyone guide me

Cant see items.remove(child) on click on delete. I think you should try deleting the child from the list and than set the adapter with updated values. #Achin
In my Expandable Listview, have three groups. I want to add different three image for that group. i tried many codes, but not working.
My code:
Main Activity:
HashMap<String, List<String>> rightDrawerListDetail = getData();
List<String> rightDrawerListTitle = new ArrayList<String>(rightDrawerListDetail.keySet());
adapterR = new CustomExpandableListAdapter(this, rightDrawerListTitle,rightDrawerListDetail);
mRightDrawerList.setAdapter(adapterR);
private HashMap<String, List<String>> getData(){
HashMap<String, List<String>> expandableListDetail = new HashMap<String, List<String>>();
ArrayList<String> arrayList = mydb.getAllAddress();
List asRider = new ArrayList();
asRider.add("hello");
List asRidee = new ArrayList();
asRidee.add("hai");
List recent = new ArrayList();
recent.add("Success");

Please anyone help to me!
Thanks in advance
In your right_drawer_group.xml add an ImageView where you want your group image to be placed, lets say groupImage.
In your getGroupView:
#Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflater.inflate(R.layout.right_drawer_group, null);
}
//Set group image
ImageView groupImage = (ImageView)convertView.findViewById(R.id.groupImage);
switch((String)getGroup(groupPosition))
{
case "As a Rider":
//groupImage set correct image
break;
case "As a Ridee":
//groupImage set correct image
break;
case "My Recent Activities":
//groupImage set correct image
break;
}
// Get the group item
String listTitle = (String) getGroup(groupPosition);
// Set group name
TextView textView = (TextView) convertView.findViewById(R.id.textGroup);
textView.setText(listTitle);
ImageView indicator = (ImageView) convertView.findViewById(R.id.groupIndicator);
if (isExpanded) {
indicator.setImageResource(R.drawable.arrowup);
} else {
indicator.setImageResource(R.drawable.arrowdown);
}
return convertView;
}
It's not the most neat solution as if you change the group name this will break, but it will work for now. Better solution would be is to pass the groups as objects containing getName and getImageId.
