How to create your own keyboard for an application in Android?

I am currently working on an application that requires a keyboard in another language (in particular, Hebrew).

The problem is that I do not know where to start. I don’t want the user to come to the application store and install a separate application in which there are only a few languages ​​to use my application.

I want the keyboard to be available in my application (i.e. it should not affect anything outside of my specific application). The way I'm doing it now is to create it as part of the main layout and just make it visible whenever the user clicks on Edit Text.

The problem with this approach is that I cannot resize it. At first I tried to use 2 different layouts (one in the res / layout folder and one in the res / layout-lnd folder), but this caused various problems in my application, which made it slower.

I am interested in 2 things, each of which should work.

• How to create a keyboard layout for reconfiguration.
• How to make a keyboard.

Here is the XML code that I use specifically for the keyboard:
