Two different return types in if else statement in data binding

Issue

I am trying to set text in TextView using data binding. I am using if else statement and if the value is true I want to set String to that TextView and in the other case I want to assign id of the String resource. My Code:

android:text="@{object.isTrue ? object.getString : object.getStringId}"

But when I try to do it I get error that Integer cannot be converted to String.

Everything is alright when I try to assign this String resource it directly like this:

android:text="@{object.getStringId}"

Is it somehow possible to use in that if else statement two different return types?

Solution

Yes, you can use Context.getString() on the second one, so that both are a String. I think this should work:

android:text="@{object.isTrue ? object.getString : context.getString(object.getStringId)}"

You don't have to import context, it's auto imported.
