Cannot refer to other View ID in Android data binding

Question

I just finished watching Advanced Data Binding - Google I/O 2016 and would like to apply the following to reduce repetition of my expression used in different views.

Answer 1

The binding process converts your IDs to properties in the binding class, and the generated names are camel-casified.

You may need to change the following line:

android:visibility="@{btn_list.visibility}"/>

To this:

android:visibility="@{btnList.visibility}"/>
