    <p>There is not enough info in your questions. However, i'll try my best :-)</p> <p>If you return more than one (type of) <code>View</code> (<code>R.layout.date_separator</code> or <code>R.layout.match_layout</code>), you have to implement the adapter's <code>getViewTypeCount</code> and <code>getItemViewType</code> methods:</p> <pre><code>@Override public int getViewTypeCount() { return 2; } @Override public int getItemViewType(int position) { Match match = matchArrayList.get(position); ... ... if (!sDate.equals(_lastDate)) { return 0; // matches R.layout.date_separator } else { return 1; // matches R.layout.match_layout } } </code></pre> <p>It has to do with the recycling of Views. When <code>convertView != null</code>, you have to make sure that the parameter <code>convertView</code> matches the original inflation of the <code>convertView</code> done at an earlier time. The method <code>getItemViewType</code> makes sure of that.</p> <p>Here is a <strong>suggested</strong> <code>getView</code> implementation:</p> <ul> <li>The inflation of the <code>convertView</code> is not entirely driven by <code>getItemViewType</code></li> <li>Switched the if and else in the second if statement (<code>SeparatorHolder</code> and <code>MatchHolder</code> were switched in calling <code>convertView.getTag</code>)</li> </ul> <p>.</p> <pre><code>public View getView(int position, View convertView, ViewGroup parent) { Match match = matchArrayList.get(position); Calendar matchTime = match.getDate(); SimpleDateFormat date = new SimpleDateFormat("dd-MM-yyyy"); SimpleDateFormat time = new SimpleDateFormat("HH:mm"); String sDate = date.format(matchTime.getTime()); SeparatorHolder separatorHolder = null; MatchHolder matchHolder = null; int itemType = getItemViewType(position); if (convertView == null) { if (itemType == 0) { convertView = inflator.inflate(R.layout.date_separator, null); separatorHolder = new SeparatorHolder(); separatorHolder.Date = (TextView) convertView.findViewById(R.id.date); convertView.setTag(separatorHolder); } else { convertView = inflator.inflate(R.layout.match_layout, null); matchHolder = new MatchHolder(); matchHolder.Time = (TextView) convertView.findViewById(R.id.time); matchHolder.HomeTeam = (TextView) convertView.findViewById(R.id.homeTeam); matchHolder.AwayTeam = (TextView) convertView.findViewById(R.id.awayTeam); matchHolder.HomeTeamImage = (ImageView) convertView.findViewById(R.id.homeTeamImageView); matchHolder.AwayTeamImage = (ImageView) convertView.findViewById(R.id.awayTeamImageView); matchHolder.TournamentImage = (ImageView) convertView.findViewById(R.id.tournamentImageView); matchHolder.TVChannelImage = (ImageView) convertView.findViewById(R.id.tvChannelImageView); convertView.setTag(matchHolder); } } else { if (itemtype == 0) separatorHolder = (SeparatorHolder) convertView.getTag(); else matchHolder = (MatchHolder) convertView.getTag(); } if (itemType == 0) { _lastDate = sDate; separatorHolder.Date.setText(sDate); } else { UrlImageViewHelper.setUrlDrawable(matchHolder.TournamentImage, match.getTournamentImage()); UrlImageViewHelper.setUrlDrawable(matchHolder.HomeTeamImage, match.getHomeTeamImage()); matchHolder.HomeTeam.setText(match.getHomeTeam()); UrlImageViewHelper.setUrlDrawable(matchHolder.AwayTeamImage, match.getAwayTeamImage()); matchHolder.AwayTeam.setText(match.getAwayTeam()); matchHolder.Time.setText(time.format(matchTime.getTime())); UrlImageViewHelper.setUrlDrawable(matchHolder.TVChannelImage, match.getTVChannelImage()); } return convertView; } </code></pre>

    2. CONo problem :) I am a bit worried about the '_lastDate'. It could mess things up, because it makes getItemViewType's return value not only based on the value of 'position', but on the value of '_lastDate' as well. If this doesn't exactly match with what happens in 'getView(...)', you still may run into problems.

    3. COIt works as far as rendering the list but as soon as I start scrolling down it force closes. Any thoughts on that? It worked just fine with only one view type...

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.
