error message getting:

junit.framework.comparisonfailure: incorrect label of listview 1 expected:<[sis-2-1-102]> was:<[android.widget.textview@4348a808]> 

at line:

assertequals("incorrect label of listview 1", "sis-2-1-102", abc); 

please help
should getting string instead of android.widget.textview@4348a808

probably should change line

assertequals("incorrect label of listview 1", "sis-2-1-102", abc); 

with this:

assertequals("incorrect label of listview 1", "sis-2-1-102", abc.equals("sis-2-1-102"));
