Android : How to achieve this UI in Android?

In one of my applications, i need to create a border for a linear layout which would look like below

I do not want to have an image and set it as background. Because then i would need to create images of various size for different devices.

If i create the layout with a linear layout and place a textview using absolute positioning, it might not look as expected in different devices.

So What is the best way to achive this UI ?
