How do I make my own keyboard for an app in androi

I am currently working on an app that requires a keyboard in a different language (Specifically Hebrew).
The problem is that I don't know where to begin. I don't want the user to have to go onto an app store, and install a separate app that has more languages in it just to use my app.
I only want the keyboard to be available in my app (i.e. it shouldn't effect anything outside my specific app). The way I am doing it right now is to create it as part of the main layout, and just make it visible whenever the user clicks on the Edit Text.
The problem with this approach is I can't get the size of it to readjust. I had originally tried using 2 different layouts (one in the res/layout folder, and one in the res/layout-lnd folder), but this caused different problems in my app, making it slower.
I am wondering 2 things, either of which should work.
How would I create the layout for the keyboard to readjust.
How would I make a keyboard correctly.
Here is the XML code that I am using specifically pertaining to the keyboard:
