Create a custom pop-up keyboard for alternate keys

Question

I am trying to create a custom popup keyboard for alternate keys in Android. Using a standard keyboard just for customization, I can do this to provide a custom layout for the pop keyboard.

I also need to customize the behavior (as in Gboard ), e.g.

(1) when a button is pressed, by default it should highlight a specific key

(2) Keys can be highlighted and also selected by moving your finger (press and hold the key for one time)

These are the links to which I refer:

Building a custom Android keyboard

Creating a SoftKeyboard with multiple / alternative characters per key

How to disable SoftKeyboard keyboard preview window?

This is a popup keyboard in Gboard

Any suggestions / help would be appreciated.

Thanks.
