    <p>In your add method you're setting the arrays to new values <code>listComments = comments;</code> That's replacing your old data with the new data.</p> <p>You could use <a href="http://developer.android.com/reference/java/lang/System.html#arraycopy%28java.lang.Object,%20int,%20java.lang.Object,%20int,%20int%29" rel="nofollow">System.arrayCopy()</a> to resize your listArrays to the new size and append the new items. A much less tedious approach, however, would be to store your arrays as <code>List&lt;String&gt;</code>, allowing you to add more items without worrying about resizing lists.</p> <p>The result would look something like this...</p> <pre><code>public class CommentsAdapter extends BaseAdapter { private LayoutInflater inflater; private List&lt;String&gt; comments; private List&lt;String&gt; numbers; private List&lt;String&gt; usernames; public CommentsAdapter(Context context) { inflater = LayoutInflater.from(context); comments = new ArrayList&lt;String&gt;(); numbers = new ArrayList&lt;String&gt;(); usernames = new ArrayList&lt;String&gt;(); } public void add(String[] comments, String[] numbers, String[] usernames) { this.comments.addAll(Arrays.asList(comments)); this.numbers.addAll(Arrays.asList(numbers)); this.usernames.addAll(Arrays.asList(usernames)); notifyDataSetChanged(); } @Override public int getCount() { if (comments == null) return 0; return comments.size(); } @Override public String getItem(int position) { return comments.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = inflater.inflate(R.layout.list_item, parent, false); convertView.setTag(new ViewHolder(convertView)); } ViewHolder holder = (ViewHolder) convertView.getTag(); holder.commentView.setText(comments.get(position)); //Other view bind logic here... return convertView; } private static class ViewHolder { public TextView commentView; public TextView numbersView; public TextView usernamesView; public Button usernameButton; public Button numberButton; public ViewHolder(View v) { commentView = (TextView) v.findViewById(R.id.listComment); numbersView = (TextView) v.findViewById(R.id.listNumber); usernamesView = (TextView) v.findViewById(R.id.listPostedBy); usernameButton = (Button) v.findViewById(R.id.listUsernameButton); numberButton = (Button) v.findViewById(R.id.listNumberButton); } } } </code></pre> <p>I also highly recommend reading this page on the Android Developer's site: <a href="http://developer.android.com/training/improving-layouts/smooth-scrolling.html" rel="nofollow">http://developer.android.com/training/improving-layouts/smooth-scrolling.html</a></p> <p>Your current adapter implementation is very inefficient, and that page should help you iron out some kinks.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
