Sure you can />

Just use the OnChildClickListener() />

private OnChildClickListener ExpandList_ItemClicked =  new OnChildClickListener() {

		public boolean onChildClick(ExpandableListView parent, View v,
				int groupPosition, int childPosition, long id) {
			// TODO Auto-generated method stub
			ExpandListChild ch =  ExpListItems.get(groupPosition).getItems().get(childPosition);
			//Your code where
			return false;
		}
		
	};

then use ExpandList.setOnChildClickListener(ExpandList_ItemClicked);

Hi EndLessMind

I inserted this section directed into the end of the onCreate callback method of your example code. Nothing has happened for me. And it seems that your ExpandableListView is unselectable. Is this suppose to happen?

Then you must be doing something wrong.
I know for a fact that i works, because i use the same approach myself in a app with almost 100k downloads.

Could it be OS version specific? I'm using Android 4.0 Emulation. Could that be the problem?

Hi again

I figure out what I did wrong. I forget to apply

ExpandList.setOnChildClickListener(ExpandList_ItemClicked);

into the onCreate method. Everything works now.

I'm still a beginner in creating custom list like this expand list. This really help a lot.

The code in the code-tag is to be for it self, just like a void.
The code in the "inline"-section, is to be placed in the same part as where you set the adapter.
In this example, it's in the onCreate-method

Can you please tell how can develope dynamic expandable listview?

Hi,
I have a question: in two function getChildView and getGroupView you have returned view. Why don't you return the TextView tv?
Please! show me why?
thanks.

The getChildView should look like this

	public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View view,
			ViewGroup parent) {
		ExpandListChild child = (ExpandListChild) getChild(groupPosition, childPosition);
		if (view == null) {
			LayoutInflater infalInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
			view = infalInflater.inflate(R.layout.expandlist_child_item, null);
		}
		TextView tv = (TextView) view.findViewById(R.id.tvChild);
		tv.setText(child.getName().toString());
		tv.setTag(child.getTag());
		return view;
	}

and the getGroupView should look like this

	public View getGroupView(int groupPosition, boolean isLastChild, View view,
			ViewGroup parent) {
		ExpandListGroup group = (ExpandListGroup) getGroup(groupPosition);
		if (view == null) {
			LayoutInflater inf = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
			view = inf.inflate(R.layout.expandlist_group_item, null);
		}
		TextView tv = (TextView) view.findViewById(R.id.tvGroup);
		tv.setText(group.getName());
		// TODO Auto-generated method stub
		return view;
	}

But the only if you are using the xml-layout for the group-item and child-item that's shown in the tutorial />
About the NullPointerExeption, are you initializing the adaper?

adapter = new ExpandListAdapter(MainActivity.this, ExpListItems); 

Hope it helps />
