How do I set the rounded corner radius of a color drawable using xml?

Question

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:

setCornerRadius(float radius) 

Is there a way to set the rounded corners in the xml?

Answer 1

Use the <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:radius="7dp" />  </shape>
