PROCEDURE(With Explanation)
Step-1
*Create a new project and give any name to application. For example "Custom Buttons".
*Drag & Drop required number of button to the View-Editor.
Step-2
*Go to configuration by taping on three dots at the upper rightmost corner.
*Here choose the button image you want to display. You can design the button yourself or simply can download from Google if its copyright free.
*This image will work as Background-Resource.
Step-3
*Now go back to View-Editor and change the buttons' one by one to look them good.
*By taping on button, you will see a new window. Now tap on "See All" and change button properties as required.
I will make following changes for all buttons as example.

Text Size= 16
Text Style= Bold
Background-Resource= Selected Image
Translation X=150
Translation Y= 80,120,160 respectively
