what is the VirtualKeyboardLayout mechanism
<p>Recently,I am working at android Input event.I meet a problem I can't understand.The keyboard device always has a *.kl and #.kcm files.They help map the scancode to keycode or char.But I don't know whether virtualKeyboard also has them.Because I saw virtual keyboard has been created in EventHub.cpp and load some map files,But I don't find it on my phone.I want to know whether the virtual keyboard has the same mechanism as physical keyboard input device?or who can tell me the real meaning of VIRTUAL_KEYBOARD on android.I think it seems not to stand for the keyboard on screen we use input char.</p>
