Description of the Onscreen Keyboard Input Method Files
Before you customize the onscreen keyboard input method files, take a few moments to familiarize yourself with
their formats and descriptions.

acter)

Note: If you want to customize the existing input method files of the onscreen keyboard, you just need to upload the custom
files.
If you want to create a new language onscreen keyboard, you should upload all three types of input method files at
a time. For the example above, you should upload “keyboard_lang.xml”, “keyboard_ime_francais.xml” and “key-
board_layout_francais.xml” files at a time.
Lang File Elements and Attributes
The following table lists the elements and attributes you need to understand in the Lang file. We recommend that
you do not edit these elements and attributes.

Description
Lang Name Specify the display name of the language.
Ime Name

Note: One Ime file can be used by multiple languages. For example, the key-
board in numeric&symbolic input mode is almost the same for each lan-
guage, you can use the template file (keyboard_ime_num.xml) as the input
method file for multiple languages.
Customizing a Lang File
