    <p>Extend Gallery and override drawChild.</p> <p>drawChild will be called for each child that needs to be drawn.</p> <pre><code>protected boolean drawChild(Canvas canvas, View child, long drawingTime) { final int left = child.getLeft(); int adjustedXOrigin = left - (getWidth() / 2) + (child.getWidth()/2); int newtop = (int) (ellipseYOffset - Math.sqrt( ellipseMinor2 * (1 - ((Math.pow(adjustedXOrigin, 2)) / ellipseMajor2)))); newtop -= (child.getHeight() / 2); if( newtop &gt;= 0 ) { child.layout(left, newtop, left + child.getWidth(), newtop + child.getHeight()); return super.drawChild(canvas, child, drawingTime); } return true; } </code></pre> <p>In onLayout I calculate ellipseYOffset. This centers the middle selected view vertically in the view, no matter the ellipse size.</p> <pre><code>ellipseYOffset = getMeasuredHeight() + (ellipseMinor - (getMeasuredHeight() / 2)); </code></pre> <p>The "if (newtop >= 0 )" part is because the view were randomly getting drawn in weird places. This stopped that.</p> <p>Edit: full code</p> <p>There is some animation stuff you don't need, i just copied and pasted my class.</p> <pre><code>public class Carousel extends Gallery { private static final float INITIAL_MINOR_RATIO = 0.75f;

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.
