How to add OR operator in XML?

Question

I have found some resources about how to implement AND, less than and greater than operator in XML for Android data-binding.

& -> &

< -> <

> -> >

However, how to add OR operator? I cannot find the related information in Android official documentation.

I have visited these sites

StackOverflow --- android databinding using "&&" logical operator - Stack Overflow

StackOverflow --- android-databinding-using-logical-operator

Escape And(&&) Operator In Android Data Binding

My expected result:

<View
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="@{viewModel.fooBoolOne ||  viewModel.fooBoolTwo ? View.VISIBLE : View.GONE}"/>```

Those are XML entity escape codes, and have nothing to do with operators. — SLaks, Jul 12 '19 at 02:16
If the operator in question is "||", then it doesn't need to be escaped in XML, it can be written as is. — Michael Kay, Jul 12 '19 at 09:12

You can use || operator in your xml without any changes.

Example :-

10 || 12
