android:text="@{register.passwordEditTextRegisterContext}"

android:text="@{register.confirmPasswordTextContext}"
android:text="@{register.nameRegisterContext}"

login layout

android:text="@{login.PasswordEditTextContext}"
android:onClick="@={() -> login.onLoginButtonClick(login)}"

registerViewModel

private val _nameRegisterContext = MutableLiveData<String>()
val NameRegisterContext: LiveData<String>
    get() = _nameRegisterContext

private val _emailEditTextRegisterContext = MutableLiveData<String>()
val emailEditTextRegisterContext: LiveData<String>
    get() = _emailEditTextRegisterContext

private val _passwordEditTextRegisterContext = MutableLiveData<String>()
val passwordEditTextRegisterContext: LiveData<String>
    get() = _passwordEditTextRegisterContext

private val _confirmPasswordTextContext = MutableLiveData<String>()

val registerCompleted: LiveData<Boolean>
    get() = _registerCompleted

fun onButtonLoginRegisterClick(view: View){

}

Although answer posted by @Miller Go Dev corrects your code somewhat, it still doesn't satisfy the needs.

The correct way would be this,

android:onClick="@={(view) -> login.onLoginButtonClick(view)}"

android:onClick="@={(view)-> register.onButtonLoginRegisterClick(view)}"

    //pass the view parameter to their respective method
