    <blockquote> <p>Any ideas?</p> </blockquote> <p>When using the default <code>progressDrawable</code> or a <code>progressDrawable</code> set through a theme all will be ok as in the constructor for the <code>RatingBar</code>(its superclass <code>ProgressBar</code> to be more precise) widget a method will be called to "make tiles" from that drawable. When using the <code>setProgressDrawable</code> method this doesn't happen and if you pass a simple <code>BitmapDrawable</code> or a <code>LayerDrawable</code>(with simple <code>BitmapDrawables</code>) that <code>Drawable</code> will simply be stretched to cover the widget's background area(what you see know).</p> <p>In order to make it work you would need to manually do what the <code>RatingBar</code> does at start, create the tiles along with the <code>ClipDrawables</code> that it uses. I've written a method for this, following the source code of the <code>ProgressBar</code> widget:</p> <pre><code>private Drawable buildRatingBarDrawables(Bitmap[] images) { final int[] requiredIds = { android.R.id.background, android.R.id.secondaryProgress, android.R.id.progress }; final float[] roundedCorners = new float[] { 5, 5, 5, 5, 5, 5, 5, 5 }; Drawable[] pieces = new Drawable[3]; for (int i = 0; i &lt; 3; i++) { ShapeDrawable sd = new ShapeDrawable(new RoundRectShape( roundedCorners, null, null)); BitmapShader bitmapShader = new BitmapShader(images[i], Shader.TileMode.REPEAT, Shader.TileMode.CLAMP); sd.getPaint().setShader(bitmapShader); ClipDrawable cd = new ClipDrawable(sd, Gravity.LEFT, ClipDrawable.HORIZONTAL); if (i == 0) { pieces[i] = sd; } else { pieces[i] = cd; } } LayerDrawable ld = new LayerDrawable(pieces); for (int i = 0; i &lt; 3; i++) { ld.setId(i, requiredIds[i]); } return ld; } </code></pre> <p>Then you would use the <code>LayerDrawable</code> returned by this method with the <code>setProgressDrawable</code> method. The <code>RatingBar</code> set its width multiplying the width of one of the state bitmaps with the number of stars, so in order to show the right amount of stars this has to be calculated as well.</p>

    1. COGreat stuff. This is definitely working for me, although I can't seem to get it to set secondaryProgress. The stars appear when clicked, but the grayed-out unselected background ones don't appear (I'm using a different drawable, R.drawable.star_off).

    2. COWhile your exact solution didn't work for me, I checked out the [Android source code for ProgressBar](http://grepcode.com/file_/repository.grepcode.com/java/ext/com.google.android/android/2.3.3_r1/android/widget/ProgressBar.java/) as you suggested, and ripping out the tileify() method worked great for me. Thanks!

    3. CO@blork Sorry about the code I posted(didn't had much time), it didn't fully replicate that method(I somehow lost that `clip` flag). I'm sure you managed to also make the stars have the correct size. The `RatingBar` sets its width by multiplying the width of one of the bitmaps with the number of stars(calculating this in the `onMeasure` method of a custom `RatingBar` should show the right amount of stars).

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.
