    <p>Well, answering my own question - here is the way I resolved the issue:</p> <ol> <li>I placed the background image on the top of my <code>ImageView</code> with <code>ImageView.setScaleType(ScaleType.FIT_START)</code></li> <li>I calculated the scale factor of my background image like so:</li> </ol> <pre> WindowManager mgr = (WindowManager) context .getSystemService(Context.WINDOW_SERVICE); DisplayMetrics metrics = new DisplayMetrics(); mgr.getDefaultDisplay().getMetrics(metrics); Drawable image = context.getResources().getDrawable(R.drawables.someImage); float scale = metrics.widthPixels / (float) image.getIntrinsicWidth(); </pre> <ol> <li>Finally, I used this scale in a custom ImageView class that loads the overlays to position and scale the view properly:</li> </ol> <pre> public class OverlayImage extends ImageView { private int imgWidth, imgHeight; private final float scale; public OverlayImage(Context context, int xPos, int yPos, float scale) { super(context); this.scale = scale; LayoutParams animParams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); animParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT); animParams.addRule(RelativeLayout.ALIGN_PARENT_TOP); animParams.leftMargin = (int) (scale * xPos); animParams.topMargin = (int) (scale * yPos); setLayoutParams(animParams); Drawable dr = context.getResources().getDrawable(R.id.someImage); setBackgroundDrawable(dr); imgWidth = dr.getIntrinsicWidth(); imgHeight = dr.getIntrinsicHeight(); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension((int) (scale * imgWidth), (int) (scale * imgHeight)); } } </pre>

    1. COInteresting stuff. This is kind of related I think to a zoomable RelativeLayout that I was trying to do a short time back. My original question and my end solution is documented here: http://stackoverflow.com/questions/6378904/extending-relativelayout-and-overriding-dispatchdraw-to-create-a-zoomable-view

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.

SQuiL has stopped working due to an internal error.

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