For API 21+, Use Clip Views

Rounded outline clipping was added to the View class in API 21. See this training doc or this reference for more info.

This in-built feature makes rounded corners very easy to implement. It works on any view or layout and supports proper clipping.

Here's What To Do:

• Create a rounded shape drawable and set it as your view's background: android:background="@drawable/round_outline"
• According to the documentation, then all you need to do is this: android:clipToOutline="true"

Unfortunately, there seems to be a bug and this XML attribute currently is not recognized. Luckily, we can set the clipping in Java:

• In your activity or fragment: View.setClipToOutline(true)

What It Looks Like:

Special Note About ImageViews

setClipToOutline() only works when the View's background is set to a shape drawable. If this background shape exists, View treats the background's outline as the borders for clipping and shadowing purposes.

This means that if you want to round the corners on an ImageView with setClipToOutline(), your image must come from android:src instead of android:background (since background is used for the rounded shape). If you MUST use background to set your image instead of src, you can use this nested views workaround:

• Create an outer layout with its background set to your shape drawable
• Wrap that layout around your ImageView (with no padding)
• The ImageView (including anything else in the layout) will now be clipped to the outer layout's rounded shape.
