    <p>My problem is simple: when I click on the icon to show the GridView, it shows me grid of photos, then I back again and again I click on icon to see GridView and it's showing 2 grids with the same photos. For example if at first I had photo 1, photo 2 I press again and it shows photo 1, photo 2, photo 1, photo 2. I thought I could solve it by adding SharedPreferences (to check if user is in GridView for the first time). Is there any better, easier way to solve my problem? GridView's code:</p> <pre><code>public static List&lt;Item&gt; items = new ArrayList&lt;Item&gt;(); </code></pre> <p>...</p> <pre><code>items.add(new Item("Name1", "Text1", R.drawable.pic_12)); items.add(new Item("Name2", "Text2", R.drawable.pic_13)); items.add(new Item("Name3", "Text3", R.drawable.pic_14)); items.add(new Item("Name4", "Text4", R.drawable.pic_15)); items.add(new Item("Name5", "Text5", R.drawable.pic_2)); GridView gridView = (GridView) findViewById(R.id.gridview); gridView.setAdapter(new ImageAdapter(this, items)); </code></pre> <p>ImageAdapter:</p> <pre><code>public class ImageAdapter extends BaseAdapter { private List&lt;Item&gt; items = new ArrayList&lt;Item&gt;(); private LayoutInflater inflater; public ImageAdapter(Context context, List&lt;Item&gt; items) { inflater = LayoutInflater.from(context); this.items = items; } @Override public int getCount() { return items.size(); } @Override public Object getItem(int i) { return items.get(i); } @Override public long getItemId(int i) { return items.get(i).drawable; } @Override public View getView(int i, View view, ViewGroup viewGroup) { View v = view; ImageView picture; TextView name; if (v == null) { v = inflater.inflate(R.layout.squareimageview, viewGroup, false); v.setTag(R.id.picture, v.findViewById(R.id.picture)); v.setTag(R.id.text, v.findViewById(R.id.text)); } picture = (ImageView) v.getTag(R.id.picture); name = (TextView) v.getTag(R.id.text); Item item = (Item) items.get(i); picture.setImageResource(item.getDrawable()); name.setText(item.name); return v; } } </code></pre> <p>Item class:</p> <pre><code>public class Item { String name; int drawable; String text; public int getDrawable() { return drawable; } public void setDrawable(int drawable) { this.drawable = drawable; } public Item(String name, String text, int id) { this.name = name; this.text = text; this.drawable = id; } public String getText() { return text; } public void setText(String text) { this.text = text; } public String getName() { return name; } public void setName(String name) { this.name = name; } } </code></pre>

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.
