android - How to create xml's id?

Question

I'm developing a dynamic keyboard application using soft keyboard sample. My application changes layout. For example I have a keyboard(has one key) then I set up the app and I can use keyboard(has one key).

I want to create an XML file after compilation and use this file in the application (reading XML file with xmlpullparser or xmlresourceparser). However, keyboard class needs XML's id. How do I create an XML id?

Answer 1

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

I get the error found tag id where item is expected when using the first method – Illhumored

Answer 2

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 );

Is your answer set id for keyboardView? – Yearbook

You're asking how to create resource IDs for XML elements, right? Or did I misunderstand. – Falconiform

Answer 3

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.
