ExpandableListView does not react and receive any click

Question

i ran into several problems when i try to insert an expandable-list into an existing activity (which is not derived from ExpandalbleListActivity).

The list does display like described in my XML layout but it does not react when i try to click / expand it.

For testing i inserted a button above the list and it receives the click. The list it self does NOT say clickable=false.

Code for the Expandable List:

<ExpandableListView
android:id="@+id/h_Zzwa_activity_listView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:groupIndicator="@color/transparent" android:clickable="true">
</ExpandableListView>

The code for initializing the list:

this.m_adapter = new HZzwaListAdapter(this, m_requests);
    listZzwa =  (ExpandableListView) findViewById(R.id.h_Zzwa_activity_listView);
    listZzwa.setAdapter(this.m_adapter)

The Adapter (which is initiated and the group.. is called)

public class HZzwaListAdapter extends BaseExpandableListAdapter
{

private List<HMyMessage> items;
private Context myContext;


public HZzwaListAdapter(Context context)
{
    myContext = context;
}

public HZzwaListAdapter(Context context, List<HMyMessage> items)
{
    myContext = context;
    this.items = items;
}





@Override
public View getChildView(int groupPosition, int childPosition,
        boolean isLastChild, View convertView, ViewGroup parent)
{

    if (convertView == null)
    {
        LayoutInflater inflater = (LayoutInflater) myContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.h_Zzwa_list_subitem,
                null);
    }

    HMyMessage message = items.get(childPosition);
    if (message != null)
    {
        TextView tvPlayerName = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_info_signText);
        tvPlayerName.setText(message.info.getSign());
    }
    return convertView;
}


@Override
public int getChildrenCount(int groupPosition)
{
    return 1;
}


@Override
public Object getGroup(int groupPosition)
{
    return null;
}


@Override
public int getGroupCount()
{
    return items.size();
}


@Override
public long getGroupId(int groupPosition)
{
    return groupPosition;
}


@Override
public View getGroupView(int groupPosition, boolean isExpanded,
        View convertView, ViewGroup parent)
{

    if (convertView == null)
    {
        LayoutInflater inflater = (LayoutInflater) myContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater
                .inflate(R.layout.h_machching_list_item, null);
    }

    // Get item and set it into the view
    HMyMessage plan = (HMyMessage) items.get(groupPosition);
    if (plan != null)
    {
        TextView pname = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_pname);
        TextView pF = (TextView) convertView
                .findViewById(R.id.h_Zzwalistitem_pText);

        if (pname != null)
        {
            pname.setText(plan.requester.getName());
        }
        if (pF != null)
        {
            pF.setText(plan.p + " unit  ");
        }
    }

    return convertView;

}


@Override
public boolean hasStableIds()
{
    return false;
}


@Override
public boolean isChildSelectable(int groupPosition, int childPosition)
{
    return true;
}

@Override
public Object getChild(int groupPosition, int childPosition)
{
    // TODO Auto-generated method stub
    return null;
}

@Override
public long getChildId(int groupPosition, int childPosition)
{
    // TODO Auto-generated method stub
    return 0;
}

}

Even when i set a listener for the click or listItemClick event nothing happens.

Why? The same thing works very good with a usual list :/

Thank you

Please add the child and group layout. With listview, there's a similar issue that listview not recieve onItemClick when listview's item has button. I met this issue before so i must implement onclick for each item in adapter.Check this article ListView doesn’t respond to OnItemClickListener and Issue 3414 ListView doesn't receive OnItemClick/OnItemLongClick for items with clickable or focusable content

EDIT: Put android:focusable="false" for the Button view or EditText view.
