I have a Gallery displaying TextViews. When it's shown, the 1st item is not displayed. This is because parent.getWidth() returns 0 at the first call. So how can I set the item's width to be a fraction of its parent gallery's width? Here is the code: <pre><code>public class GalleryActivity extends Activity { private Gallery gallery; public void onCreate (Bundle savedInstanceState) { super.onCreate (savedInstanceState); setContentView (R.layout.gallery); gallery = (Gallery) findViewById (R.id.gallery); gallery.setAdapter (new Adapter ()); } private class Adapter extends BaseAdapter { private String[] items = {"A", "B", "C", "D", "E", "F"}; public int getCount () { return items.length; } public Object getItem (int position) { return items[position]; } public long getItemId (int position) { return position; } public View getView (int position, View convertView, ViewGroup parent) { TextView view = new TextView (GalleryActivity.this); view.setText (getItem (position).toString ()); view.setBackgroundColor (Color.GRAY); view.setGravity (Gravity.CENTER); view.setLayoutParams (new Gallery.LayoutParams (parent.getWidth () / 3, LayoutParams.FILL_PARENT)); return view; } } } </code></pre> layout/gallery.xml <pre><code><?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Gallery android:id="@+id/gallery" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1" android:scrollbars="horizontal" android:spacing="1dp"></Gallery> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="3"></TextView> </LinearLayout> </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.
