    <p>I changed arcones' code, so the method works with Bitmaps instead of Sprites. </p> <pre><code>import android.graphics.Bitmap; import android.graphics.Color; import android.graphics.Rect; public class KollisionsErkennung { /** * @param bitmap1 First bitmap * @param x1 x-position of bitmap1 on screen. * @param y1 y-position of bitmap1 on screen. * @param bitmap2 Second bitmap. * @param x2 x-position of bitmap2 on screen. * @param y2 y-position of bitmap2 on screen. */ public static boolean isCollisionDetected(Bitmap bitmap1, int x1, int y1, Bitmap bitmap2, int x2, int y2) { Rect bounds1 = new Rect(x1, y1, x1+bitmap1.getWidth(), y1+bitmap1.getHeight()); Rect bounds2 = new Rect(x2, y2, x2+bitmap2.getWidth(), y2+bitmap2.getHeight()); if (Rect.intersects(bounds1, bounds2)) { Rect collisionBounds = getCollisionBounds(bounds1, bounds2); for (int i = collisionBounds.left; i &lt; collisionBounds.right; i++) { for (int j = collisionBounds.top; j &lt; collisionBounds.bottom; j++) { int bitmap1Pixel = bitmap1.getPixel(i-x1, j-y1); int bitmap2Pixel = bitmap2.getPixel(i-x2, j-y2); if (isFilled(bitmap1Pixel) &amp;&amp; isFilled(bitmap2Pixel)) { return true; } } } } return false; } private static Rect getCollisionBounds(Rect rect1, Rect rect2) { int left = (int) Math.max(rect1.left, rect2.left); int top = (int) Math.max(rect1.top, rect2.top); int right = (int) Math.min(rect1.right, rect2.right); int bottom = (int) Math.min(rect1.bottom, rect2.bottom); return new Rect(left, top, right, bottom); } private static boolean isFilled(int pixel) { return pixel != Color.TRANSPARENT; } } </code></pre> <p>For my needs it works fast enough.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
