You can do it by customizing a RadioGroup with two RadioButton as child.

Here is some hints-

Steps can be like this

Create a drawable shape of type rectangle in xml with corner and stroke. Use it for the RadioGroup background.
Create selector using the similar shapes (for color as per selected and un-selected one)for two RadioButon and set them as individual background.
Create one color drawable in xml for selected and un-selected states and set its as textColor to the RadioButton
Set android:buttonattribute of RadioButton to null. Here is an example which i have posted as answer to an SO question - How to custom switch button?
