Hi, You can set an OnItemClickListener on the ExpandableLayoutListview. Next, you retrieve an ExpandableLayoutItem, from it you have access to the header and the content layout by getHeaderRelativeLayout(), getContentRelativeLayout(). To set an OnClickListener or retrieve data find your view with findViewById and do what you want to do.

Also wondering this.. Want to change the content inside the header dynamically but can't seem to figure out how.

I also met the issue,and I just solved it.

part of the code is as follows:

mEplListView = (ExpandableLayoutListView) mView.findViewById(R.id.epl_lv); mEplListView.setAdapter(arrayAdapter); mEplListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { mEplListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.e(TAG, "view:" + view.getClass().getName() + "\t" + position + "\t" + id); mEplItem = (ExpandableLayoutItem) view.findViewById(R.id.row); RelativeLayout content = mEplItem.getContentRelativeLayout(); btn = (Button) content.findViewById(R.id.btn); btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Log.e(TAG, "Click"); } }); } });

You need to add android:descendantFocusability="afterDescendants " in the view_item.xml,and add android:focusable="true" and android:clickable="true" in the view_content.xml for your button.
