Answer 1

First of all there should not be = after @ because it indicates two-way binding and there is no meaning of two-way binding with TextView.

To concate last name you can use + operator

android:text="@{task.assignedTo.firstName + task.assignedTo.lastName}"

and to concate it with some custom String :

android:text="@{task.assignedTo.firstName + ` - ` + task.assignedTo.lastName}"
