Data Binding - How to write multi-line declarations?

Question

Is there any way to write multi-line code with DataBinding library?

I tried following, but it complains about XML format

android:text="@{             viewModel.subscriptionExpiration == null                 ? viewModel.field1                 : viewModel.field2         }" 

With following error: Error:(80) Error parsing XML: not well-formed (invalid token)

Single-line alternative works, but I find it less readable:

android:text="@{viewModel.subscriptionExpiration == null ? viewModel.field1 : viewModel.field2}"

I tried doing some digging and couldn't find an answer. I don't know that you can break up string literals that way in xml. As an alternative I would recommend offloading the evaluation to the viewModel instead, in the form of:

android:text="@{viewModel.subscriptionStatus}" 

then in your viewModel class

@Bindable public String getSubscriptionStatus(){     return getSubscriptionExpiration() == null             ? getField1()             : getField2(); }
