In the Employee_List activity , you can access the data through index of child and group obtaining from ChildClickListener
myList.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2,
int arg3, long arg4) {
// TODO Auto-generated method stub
//Here You can access the child data by
final EntryItem country = (EntryItem) listAdapter .getChild(arg2, arg3);
//From here you can pass the data through Intent

ExpandableListActivity how to check/uncheck checkbox in all children of a group

I have a ExpandableListActivity that has groups and children. the chidren have a checkbox.
I've overridden setOnGroupExpandListener for when the user tap the group.
How can i check/uncheck the checkbox for each child for a particular group?
I've tried getting the adapter and calling getChild using the groupPosition but i'm lost in how do do this.
thanks in advance

try creating an array of arrays of booleans called checked. then in getChildView check if that spot in the array is true, if so so the checkbox to checked.
then when you expand a parent loop through every element in that two dimential array setting them all to true and then calling notifyDataSetChanged
boolean [][] checked;
then in on expand
for(int i =0; i < checked[groupPosition].size; i++)
{
checked[groupPosition][i] = true;
}
notifyDataSetChanged();
in getChildView you should also but this
cb.setChecked(checked[groupPosition][childPosition]);
a sim thing can be done to uncheck them by setting it to false. just remember to update this array when a user checks or unchecks a button so when the list views are recycled you dont get randomly checked boxes.

It does not make any sense If I just disable the adapter, volley request got get success and load data in my domain classes.

I think the mistake is that you want to fill ExpandableListView with data that are not loaded yet. In your onCreateView the myMapCollection is still empty. It is loaded after some time when the volley finishes its asyncTask. You need to refresh your UI when you get successful response that volley finished loading data.

How to incorporate a popup window when selecting a child in an expandable list

Here's a pretty cookie cutter program that expands a list, and then when you click a child, it pops a message saying, "Child Clicked". But I want the expandable list to consists of recipes so that when clicked, it shows a popup window of the ingredients. I tried making it an arraylist of objects instead of strings, and having the objects contain the list of ingredients, but I got all tangled up when trying to display the ingredients.. Thanks in advance!

Before we begin, note that Recipes is a confusing name for an Activity. I would highly recommend changing the name to follow the standard convention of ending with the word "Activity" (e.g., RecipeActivity).
First you need to create a Recipe object so you can store the name and ingredients together. This object can be as simple or as complex as you need, but let's pretend it looks something like this:
import java.util.List;
public class Recipe {
private String name;
private List<String> ingredients;
private List<String> directions;
#Override
public String toString() {
// By default, the Adapter classes in Android will call toString() on
// your object to figure out how it should appear in lists. To make sure
// the list displays the recipe name, we return the recipe name here.
return name;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<String> getIngredients() {
return ingredients;
}
public void setIngredients(List<String> ingredients) {
this.ingredients = ingredients;
}
public List<String> getDirections() {
return directions;
}
public void setDirections(List<String> directions) {
this.directions = directions;
}
}
Notice that we override toString() for this object and return the recipe name. This way, when we ask our adapter class to display a list of Recipe objects, it knows what text should be shown for each item in the list.
When creating the data for your list, instead of:
ArrayList<String> arrayChildren = new ArrayList<String>();
Use:
List<Recipe> arrayChildren = new ArrayList<Recipe>();
(Note: You might need to modify the Parent class to take List<Recipe> or the generic List<?> for the children if that field is only accepting List<String> right now.)
Let's add one sample Recipe object:
Recipe salsa = new Recipe();
salsa.setName("Pineapple Salsa");
salsa.setIngredients(Arrays.asList("pineapple", "cilantro", "lime", "jalapeno"));
salsa.setDirections(Arrays.asList("Blend ingredients and enjoy"));
arrayChildren.add(salsa);
Now that your list is backed by Recipe objects instead of just strings, it's simply a matter of getting that object when a list item is clicked. Here's how you might do this:
mExpandableList.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
// Get the selected recipe
Recipe recipe = (Recipe) parent.getExpandableListAdapter()
.getChild(groupPosition, childPosition);
// Build a string listing the ingredients
StringBuilder message = new StringBuilder("Ingredients:\n");
for (String ingredient : recipe.getIngredients())
message.append("\n").append(ingredient);
// Display a dialog listing the ingredients
new AlertDialog.Builder(MyGreatHelloWorldActivity.this)
.setTitle(recipe.getName()).setMessage(message)
.setPositiveButton("Yum!", null).show();
// Return true because we handled the click
return true;
}
});
Update: Here's how you can complete the task with a no-frills adapter for expandable lists.
I created a generic class called ExpandableListGroup (equivalent to your Parent class) to hold the children. The class is generic so it will work with any kind of objects, but we'll use it with Recipe objects.
import java.util.List;
public class ExpandableListGroup<T> {
private String name;
private List<T> children;
public ExpandableListGroup(String name, List<T> children) {
this.name = name;
this.children = children;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<T> getChildren() {
return children;
}
public void setChildren(List<T> children) {
this.children = children;
}
#Override
public String toString() {
return name;
}
}
Then I created the following generic ExpandableListArrayAdapter class:
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseExpandableListAdapter;
import android.widget.TextView;
public class ExpandableListArrayAdapter<T> extends BaseExpandableListAdapter {
private List<ExpandableListGroup<T>> groups;
private LayoutInflater inflater;
public ExpandableListArrayAdapter(Context context,
List<ExpandableListGroup<T>> groups) {
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
this.groups = groups;
}
#Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
ExpandableListGroup<T> group = getGroup(groupPosition);
if (convertView == null) {
convertView = inflater.inflate(
android.R.layout.simple_expandable_list_item_1, parent,
false);
}
TextView text = (TextView) convertView;
text.setText(group.toString());
return convertView;
}
#Override
public View getChildView(int groupPosition, int childPosition,
boolean isLastChild, View convertView, ViewGroup parent) {
T item = getChild(groupPosition, childPosition);
if (convertView == null) {
convertView = inflater.inflate(
android.R.layout.simple_expandable_list_item_1, parent,
false);
}
TextView text = (TextView) convertView;
text.setText(item.toString());
return convertView;
}
#Override
public T getChild(int groupPosition, int childPosition) {
return groups.get(groupPosition).getChildren().get(childPosition);
}
#Override
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
#Override
public int getChildrenCount(int groupPosition) {
return groups.get(groupPosition).getChildren().size();
}
#Override
public ExpandableListGroup<T> getGroup(int groupPosition) {
return groups.get(groupPosition);
}
#Override
public int getGroupCount() {
return groups.size();
}
#Override
public long getGroupId(int groupPosition) {
return groupPosition;
}
#Override
public boolean hasStableIds() {
return true;
}
#Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
}
Now, here's how you tie it all together:
// Create one list per group
List<Recipe> appetizers = new ArrayList<Recipe>(),
desserts = new ArrayList<Recipe>();
// TODO: Create Recipe objects and add to lists
List<ExpandableListGroup<Recipe>> groups = Arrays.asList(
new ExpandableListGroup<Recipe>("Appetizers", appetizers),
new ExpandableListGroup<Recipe>("Desserts", desserts));
mExpandableList.setAdapter(new ExpandableListArrayAdapter<Recipe>(this,
groups));
