Only the return value of the string ToString () method is shown in the list, and I want the name of the list item, so adding the following method to the class of the data unit solves the problem

@Overridepublic String toString () {return getcontrolname ();}

The default in the superclass is:
@Overridepublic String toString () {return super.tostring ();}
