    <p>I have a customized BaseAdapter for my listView with this code:</p> <pre><code>public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { } else { holder = (ViewHolder) convertView.getTag(); } convertView = mInflater.inflate(R.layout.user_submissions_customisation, null); holder = new ViewHolder(); holder.JournalName = (TextView) convertView.findViewById(R.id.JournalName); holder.SubmissionTitle = (TextView) convertView.findViewById(R.id.SubmissionTitle); holder.SubmissionDate = (TextView) convertView.findViewById(R.id.SubmissionDate); holder.statusOk=(ImageView)convertView.findViewById(R.id.statusOkImage); holder.statusRejected=(ImageView)convertView.findViewById(R.id.statusRejectedImage); holder.statusProcessing=(ImageView)convertView.findViewById(R.id.statusProcessingImage); convertView.setTag(holder); ImageView statusOk=(ImageView)convertView.findViewById(R.id.statusOkImage); ImageView statusRejected=(ImageView)convertView.findViewById(R.id.statusRejectedImage); ImageView statusProcessing=(ImageView)convertView.findViewById(R.id.statusProcessingImage); MDPIActivity mdpi = new MDPIActivity(); Context context =mdpi.getContext(); LocalDatabase localDatabase = new LocalDatabase(context); //Instantiation of the DB int status = localDatabase.getSubmissionStatus(position+1); if (status==102 | status==19) { statusRejected.setVisibility(View.VISIBLE); } else { if (status==29) { statusOk.setVisibility(View.VISIBLE); } else { statusProcessing.setVisibility(View.VISIBLE); } } holder.JournalName.setText(submissionsArrayList.get(position).getJournalTitle()+"-"+submissionsArrayList.get(position).getID()); holder.SubmissionTitle.setText(submissionsArrayList.get(position).getTitle()); holder.SubmissionDate.setText(submissionsArrayList.get(position).getDate()); return convertView; } static class ViewHolder { TextView JournalName; TextView SubmissionTitle; TextView SubmissionDate; ImageView statusOk; ImageView statusRejected; ImageView statusProcessing; } </code></pre> <p>All works wel but the creation of the list on the display and the scrolling is pretty slow. I used this for éy list too:</p> <pre><code>android:fastScrollEnabled="true" android:scrollingCache="true" android:smoothScrollbar="true" </code></pre> <p>But the view changing from the previeous view to the listview is slow and the scrolling of the list too.</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).
