    <p>I have a GridView in android which I fill it with data retrieved from a xml resource.<br> For example I have 15 items in the GridView which are placed in order. The overall height exceeds the Screen height so i have to scroll to see the rest of the items.<br> The problem is when I scroll back up, the order of the invisible rows have changed. It's a mysterious behavior as sometimes items swap rows with each other. Here is my <code>getView</code> method:</p> <pre><code>public class ImageAdapter extends BaseAdapter { public ImageAdapter(Context c, NodeList cuu) { cu = cuu; } public int getCount() { Log.d("Node Count",cu.getLength()+""); return cu.getLength(); } public Object getItem(int position) { return position; } public long getItemId(int position) { return position; } public View getView(int position, View convertView, ViewGroup parent) { View myView = convertView; if (convertView == null) { Node nd = cu.item(position); Log.d("nodes","Pos: "+(position)+" Name: "+nd.getNodeName()+" Title: "+nd.getAttributes().getNamedItem("title").getTextContent()); int catID = Integer.parseInt(nd.getAttributes().getNamedItem("id").getTextContent()); LayoutInflater li = getLayoutInflater(); myView = li.inflate(R.layout.grid_item, null); ImageView imageView = (ImageView) myView.findViewById(R.id.grid_item_image); myView.setLayoutParams(new GridView.LayoutParams(70, 100)); id.download(nd.getAttributes().getNamedItem("icon").getTextContent(),imageView); TextView textView = (TextView) myView.findViewById(R.id.grid_item_text); textView.setText(nd.getAttributes().getNamedItem("title").getTextContent()); myView.setTag((Object) catID); }else{ //Log.d("nodes","Pos: "+(position)); } return myView; } private NodeList cu = null; } </code></pre> <p><strong>Update:</strong> Well, it's rather odd. After some more debugging I noticed that in the GridView, the Adapter skips the 13th position, meaning it returns 1 instead of 13 and then moves on to 14!!! (I guess the 13 is bad luck!)</p>

    1. COThe `Adapter` will not skip positions by itself. Post the full code for your adapter.

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.
