On the android website, there is a section about color drawables. Defining these drawables in xml looks like this:
<resources> <drawable name="solid_red">#f00</drawable> <drawable name="solid_blue">#0000ff</drawable> <drawable name="solid_green">#f0f0</drawable> </resources>
In the java api, they have thr following method to define rounded corners:
Is there a way to set the rounded corners in the xml?
<shape> tag to create a drawable in XML with rounded corners. (You can do other stuff with the shape tag like define a color gradient as well).
Here's a copy of a XML file I'm using in one of my apps to create a drawable with a white background, black border and rounded corners:
<?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#ffffffff"/> <stroke android:width="3dp" android:color="#ff000000" /> <padding android:left="1dp" android:top="1dp" android:right="1dp" android:bottom="1dp" /> <corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" /> </shape>
mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).
I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.
