Android 9 Development Cookbook - Third Edition

Using a list

We can also create a list of items to select from with various list setting methods, including the following:

.setItems() 
.setAdapter() 
.setSingleChoiceItems() 
.setMultiChoiceItems() 

As you can see, there are also methods for single-choice (using a radio button) and multi-choice lists (using a checkbox).

You can't use both the Message and the Lists, as setMessage() will take priority.
