  (I want to have only one group item, therefore the item group count is 1).</p>
  
  <p>Please help me to find where am I wrong, thanks alot.</p>
  
  <p>This is my adapter:</p>
  
  <pre><code>class chatListAdapter extends BaseExpandableListAdapter {
  private String objectsIdInsideAdapter;
  private List&lt;String&gt; commentsInsideAdapter = new ArrayList&lt;String&gt;();
  private List&lt;String&gt; FacebookIdInsideAdapter=new ArrayList&lt;String&gt;();
  private List&lt;String&gt; NamesInsideAdapter =new ArrayList&lt;String&gt;();
  private Context mContext;
  
  chatListAdapter(String objectId,Context ctx,List&lt;String&gt; comments,List&lt;String&gt; face,List&lt;String&gt; names){
      objectsIdInsideAdapter=objectId;
      mContext=ctx;
      commentsInsideAdapter=comments;
      FacebookIdInsideAdapter=face;
      NamesInsideAdapter=names;
  }
  @Override
  public Object getChild(int arg0, int arg1) {
      // TODO Auto-generated method stub
      return NamesInsideAdapter.get(arg1);
  }
  
  @Override
  public long getChildId(int arg0, int arg1) {
      // TODO Auto-generated method stub
      return 0;
  }
  
  @Override
  public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View v,
          ViewGroup parent) {
      // TODO Auto-generated method stub
  
      LayoutInflater inflater = getLayoutInflater();
  
  
      if(v==null){
           v = inflater.inflate(R.layout.chat_item, parent, false);
      }
  
  
  
      String comment =commentsInsideAdapter.get(position);
      Button sendCommentBtn =(Button) v.findViewById(R.id.chatitemSendComment);
          TextView commentView= (TextView) v.findViewById(R.id.chateitemViewComment);
          commentView.setText(comment);
          TextView commentName =(TextView) v.findViewById(R.id.chatitemfreindName);
          commentName.setText(NamesInsideAdapter.get(position));
          EditText commentText= (EditText) v.findViewById(R.id.chatitemEnterComment);
          commentText.setVisibility(View.GONE);
          sendCommentBtn.setVisibility(View.GONE);
  
  
  
  
      return v;
  }
  
  @Override
  public int getChildrenCount(int arg0) {
      // TODO Auto-generated method stub
      return NamesInsideAdapter.size();
  }
  
  @Override
  public Object getGroup(int arg0) {
      // TODO Auto-generated method stub
      return null;
  }
  
  @Override
  public int getGroupCount() {
      // TODO Auto-generated method stub
      return 1;
  }
  
  @Override
  public long getGroupId(int arg0) {
      // TODO Auto-generated method stub
      return 0;
  }
  
  @Override
  public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
          ViewGroup parent) {
      // TODO Auto-generated method stub
      View v = convertView;
  
      if (v == null) {
          LayoutInflater inflater = getLayoutInflater();
          v = inflater.inflate(R.layout.chat_item_group_layout,parent, false);
      }
  
      TextView groupName = (TextView) v.findViewById(R.id.groupName);
      TextView groupDescr = (TextView) v.findViewById(R.id.groupDescr);
  
      groupName.setText("view comments");
      groupDescr.setText("groupDSCR");
  
  
      return v;
  
  }
  
  @Override
  public boolean hasStableIds() {
      // TODO Auto-generated method stub
      return false;
  }
  
  @Override
  public boolean isChildSelectable(int arg0, int arg1) {
      // TODO Auto-generated method stub
      return false;
  }
  </code></pre>
  
  <p>and this is the code in the main Activity:</p>
  
  <pre><code>ExpandableListView  chat =(ExpandableListView) v.findViewById(R.id.ExpList); 
  
       String faceids =facebookIdChatInside.get(position);
       String comments = commentInside.get(position);
       String namesChat =nameChatInside.get(position);
       List&lt;String&gt; chatItems = new ArrayList&lt;String&gt;(Arrays.asList(comments.split(",")));
       List&lt;String&gt; facebookids = new ArrayList&lt;String&gt;(Arrays.asList(faceids.split(",")));
       List&lt;String&gt; namesList = new ArrayList&lt;String&gt;(Arrays.asList(namesChat.split(",")));
       chatItems.add(" ");
       facebookids.add(id);
       namesList.add(name);
  
  
       chatListAdapter chatA =new chatListAdapter(objectsId.get(position),profileContext,chatItems,facebookids,namesList);
       chat.setAdapter(chatA);
  </code></pre>
  
  <p>I checked it, and those 3 Lists are not empty.</p>
