I am using the following code to get rounded corners as well as a colored outline:
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).
Following code may help you:
<?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>
Use this customize according to your need.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="@android:color/transparent" />
<stroke
android:width="4dp"
android:color="@android:color/holo_blue_light" />
<corners android:radius="6dp" />
</shape>
