    <p>While the above answer works, Romain Guy (a core Android developer) shows <a href="http://www.curious-creature.org/2012/12/11/android-recipe-1-image-with-rounded-corners/" rel="noreferrer">a better method</a> in his blog which uses less memory by using a shader not creating a copy of the bitmap. The general gist of the functionality is here:</p> <pre><code>BitmapShader shader; shader = new BitmapShader(bitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP); Paint paint = new Paint(); paint.setAntiAlias(true); paint.setShader(shader); RectF rect = new RectF(0.0f, 0.0f, width, height); // rect contains the bounds of the shape // radius is the radius in pixels of the rounded corners // paint contains the shader that will texture the shape canvas.drawRoundRect(rect, radius, radius, paint); </code></pre> <p>The advantages of this over other methods is that it:</p> <ul> <li><strong>does not create a separate copy of the bitmap,</strong> which uses a lot of memory with large images [vs most of the other answers here]</li> <li>supports <strong>antialisasing</strong> [vs clipPath method]</li> <li>supports <strong>alpha</strong> [vs xfermode+porterduff method]</li> <li>supports <strong>hardware acceleration</strong> [vs clipPath method]</li> <li>only <strong>draws once to the canvas</strong> [vs xfermode and clippath methods]</li> </ul> <p>I've created a <a href="https://github.com/vinc3m1/RoundedImageView" rel="noreferrer">RoundedImageView</a> based off this code that wraps this logic into an ImageView and adds proper <code>ScaleType</code> support and an optional rounded border.</p>

    1. COin your `/ example / res / layout / rounded_item.xml ` why do you specify an image src when all your sources are hardcoded ? Nice demo, just way overkill.

    2. COyour sample has a serious out-of-memory issue, just like the original sample of Romain Guy. I still don't know what causes it, but just like his code, this is a really hard thing to find. If you can't see a crash from the app because of OOM, you can rotate the app multiple times till it occurs (depends on your device, ROM, etc...) . I've reported about it in the past here: http://stackoverflow.com/questions/14109187/using-a-rounded-corners-drawable

    3. COalso, this solution (that is written here) just doesn't work if you use it directly on a bitmap. you need to create a drawable that will use it. it doesn't really change the bitmap at all. tested on android 4.1 .

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).
