Adding new items to the end of the ListView android

Question

I have a ListView whose items I fetch from a JSON response from a Web API. It basically has comments in it. The problem is that when the user adds new comment, the item gets added to the top of the List. I want the item to be added at the end.

Here is my code:-

MyList.java

private void GetComments() 
{
    // TODO Auto-generated method stub
      scrollNews.scrollTo(0, scrollNews.getBottom());

      commentsList.setVisibility(View.VISIBLE);

        String items;
        try
        {

            String getRequestForComments = myUrl;
            items = new FetchItems().execute(getRequestForComments).get();


            ArrayList<HashMap<String, String>> getList = new GetList().execute(items).get();






            itemsAdapter = (ListAdapter) new CommentsAdapter(NewsDetails.this, getList);

            commentsList.setAdapter(itemsAdapter);




        }
        catch (InterruptedException e) 
        {

            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
        catch (ExecutionException e) 
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

mylist.xml

<ListView
    android:id="@+id/android:list"
    android:visibility="invisible"
    android:transcriptMode="alwaysScroll"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_above="@+id/getdata" 
    android:divider="#b5b5b5"
    android:dividerHeight="1dp"
    android:layout_weight="6"
    android:layout_gravity="bottom"
    android:listSelector="@drawable/list_selector" 
    android:padding="5dp"/>

Can anyone help me with this?
