    <p>I know their are a lot of question relative to refreshing listView, but none of them are anwering my problem (as far as I know).</p> <p><strong>I'm trying to change my item view when clicking on it in my list view.</strong></p> <p>To change the view I've got a <code>boolean isClicked</code> on my POJO :</p> <pre><code> networksListView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView&lt;?&gt; _adapter, View view, int pos, long id) { myApp.networksGlobal.networks.get(pos); myApp.networksGlobal.networks.get(pos).isClicked = !myApp.networksGlobal.networks.get(pos).isClicked; adapter.notifyDataSetChanged(); } }); </code></pre> <p>When I click on the item <code>isClicked</code> switch from true to false, and on my <code>getView</code> listAdapted I'm switching the view type :</p> <pre><code> @Override public View getView(int position, View convertView, ViewGroup parent) { Network network = (Network) getItem(position); NetworkItemView networkItemView; if (convertView == null) { networkItemView = NetworkItemView_.build(context); } else { networkItemView = (NetworkItemView) convertView; } networkItemView.bind(network); if (network.isClicked) { networkItemView.networkItemButtonLayout.setVisibility(View.VISIBLE); } else { networkItemView.networkItemButtonLayout.setVisibility(View.GONE); } return networkItemView; } </code></pre> <p>On the first click everything is working great, the Toast is shown an the Layout <code>networkItemButtonLayout</code> is set to visible.</p> <p>But if I click a second time on the same item : <strong>nothing happend</strong>. No Toast is shown and no changes on the Layout visibility.</p> <p>If I comment <code>adapter.notifyDataSetChanged()</code> the Toast is shown for every click. So I guess the problem is why the call to <code>adapter.notifyDataSetChanged()</code>. So tried several work around (<code>adapter.notifyDataSetChanged()</code> and <code>networksSearchListView.invalidateViews()</code>) but nothing do the trick, and I can't find a way to click several time on my item.</p> <p>Does I'm using 'notifyDataSetChanged' the proper way ?</p>

    2. COI'm switching the isClicked at every `networksSearchListViewItemClicked` so I can change the visibility of `networkItemButtonLayout` at every click (first click show the button Layout, second click hide the button Layout)

    3. COmy guess is that `adapter.notifyDataSetChanged();` is getting called repeatedly and locking up your listview. i can only assume that for some reason, perhaps it's a rogue method and perhaps every item is percieved to be clicked and the method is ran more than once. using a conventional listview `ItemClickListener` might work better. of course i can only guess.

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.
