Implementing ATM Numeric input behaviour in Android EditText

Question

How can I implement the following input behaviour using EditText in Android. Is there a existing library to implement this behaviour or if else, what would the logic be like? This behaviour can be seen on ATM machines as well.

Here's a gif that demonstrates this behaviour in an Android app:

As observed, the input starts with the last digit and proceeds to the left while appending necessary commas and decimal separation (2 decimals). I couldn't find any library that implements this behaviour.

Can you point me in the right direction with an existing implementation or a library?

Hi @SubhechhuKhanal Thanks for the comment. I built a library based on that solution. Check my answer :) — Dinuka Jay, Jul 17 '17 at 04:35

I resolved this and built a custom library based on Subhechhu Khanal's link to a resolved thread. Anyone who needs this behaviour can use the custom library and customise it as required.

I encourage the community to make this library better. Thanks!
