You can define ids using an ids.xml file in your res/values directory. Here's an example:

<resources>
    <item type="id" name="my_keyboard" />
</resources>

In code, you would set the id like so:

keyboardView.setId( R.id.my_keyboard );

Answer 2

It can be defined in ids.xml or any custom file like constants.xml inside your res\values folder.

Examples:

<resources>
    <item type="id" name="keyboard" />
</resources>

and can be accessed in the code as following:

R.id.keyboard

XML files are compiled (binary XML) and thus you don't create them at runtime.

If you want to change your keyboard layout dynamically, you'll do that programmatically rather than in XML.
