I'm having trouble with setting an OnClickListener to list items in my ExpandableListActivity. The code structure matches the following example:
ExpandableListAdapter mAdapter;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Assign the adapter
mAdapter = new MyExpandableListAdapter();
setListAdapter(mAdapter);
}
public class MyExpandableListAdapter extends BaseExpandableListAdapter {
private String[] groups = { "foo", "bar"};
private String[][] children = {
{"fooA", "barA"},
{"fooB", "barB"}
};
public Object getChild(int groupPosition, int childPosition) {
return children[groupPosition][childPosition];
}
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
public int getChildrenCount(int groupPosition) {
return children[groupPosition].length;
}
public TextView getGenericView() {
// Layout parameters for the ExpandableListView
AbsListView.LayoutParams lp = new AbsListView.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT, 64);
TextView textView = new TextView(Calculations.this);
textView.setLayoutParams(lp);
// Center the text vertically
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
// Set the text starting position
textView.setPadding(64, 0, 0, 0);
return textView;
}
public View getChildView(int groupPosition, int childPosition, boolean isLastChild,
View convertView, ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getChild(groupPosition, childPosition).toString());
textView.setPadding(98, 0, 0, 0);
return textView;
}
public Object getGroup(int groupPosition) {
return groups[groupPosition];
}
public int getGroupCount() {
return groups.length;
}
public long getGroupId(int groupPosition) {
return groupPosition;
}
public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getGroup(groupPosition).toString());
return textView;
}
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
public boolean hasStableIds() {
return true;
}
}
Once I'm able to set the listener, I'll most likely do something like this:
// Listener
{
switch(groupPosition) {
case 0:
switch(childPosition) {
case 0:
selected = 00;
return true;
}
}
}// Close listener
Please tell me if I'm not being clear enough.
You should override onChildClick() in your activity.
boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id)
Override this for receiving callbacks when a child has been clicked.

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.

Thank you for your help
I have created a expandable list view and two radio buttons in it.
I want to get the value of the radio button which is selected when some button is pressed in my main Activity. My ExpandableListView is working properly but i am not able to get the radio button which is selected in main activity.

Use onChildClick method in your code.This method is automatically called when you click on child item
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
//get your radio here from the view v and do whatever you want
return true;
}
I wrote a 3 level expandable list code which is like that:
A
|_B
|_C
D
|_E
|_F
But in my list, each row consists of buttons, edittexts etc. And I'm adding childs dynamically as you can see at the below code.
I need some help about 2 things.
1) When I click A, B is opening but when i clicked B, C is not showing in the screen.
2) When i click A or D, group position is not changing always the same which is 0. Because of that A always expands.
You can find the codes below, thank you :)
Beginning of the activity I wrote these:
public static int FIRST_LEVEL_COUNT = 1;
public static int SECOND_LEVEL_COUNT = 1;
public static int THIRD_LEVEL_COUNT = 1;
boolean firstLevel_Expanded = false;
boolean secondLevel_Expanded = false;
And then calling expandable list view from xml:
demand_table = (ExpandableListView) dialog.findViewById(R.id.demandresponsetable);
demand_table.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
demand_table.setAdapter(new ParentLevel(this));

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
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
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
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
final String childText = (String) getChild(groupPosition, childPosition);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) this._context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
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 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());
}
});
}
