I'm trying to override getItemViewType and return a different view type for my footer, but integer comparison is failing within the function:

enter image description here

This image shows a debug session where the input position is 21 and the the private List mValues has a size of 21, however when I pushed "step over" the conditional code is skipped.

If both integers are equal, why does position == mValues.size() return false?

I cleaned and rebuilt my project before running.

UPDATE:

It works when the integers are hardcoded:

but not when I use the input parameter:

UPDATE

I added a Log statement as the first line of the function

Log.e("MYAPP", "position: " + position + ", evaluates: " + (position == 21));

and in my monitor I see: position: 21, evaluates: true

However, my breakpoint at return FOOTER_VIEW; is never called and none of the functions related to the footer view are ever called.

UPDATE:

Heres the full Adaptor: https://gist.github.com/fergusom/79c6d5d9b1fd5e8348949d114a0159d5

Note that I updated the code to compute a boolean first, but it still fails even though the boolean prints out true in the logs

    What type is mValues (runtime type)? Did you try stepping into mValues.size()? Can you verify that it returns 21? Commented Sep 2, 2016 at 16:12
  • If I replace mValues.size() with 21, it still fails, added a picture that shows this Commented Sep 2, 2016 at 16:14

    Don't trust the debugger! Put logs statements inside and outside the if. Commented Sep 2, 2016 at 16:16

    The debugger may highlight the wrong line because of code optimizations. Commented Sep 2, 2016 at 16:18

    what is mValues actually? Commented Sep 2, 2016 at 16:25

Reset to default

Give the jvm no chance:

if(new Integer(position).equals(new Integer(mValues.size()))

If the Integer constructor fails you'll know what the values were in the exception

I tried going one step further and creating a boolean to use in the conditional and it still failed even when the boolean prints out true in a log. check out the full gist in the last update
Wait what? You printed a boolean variable, gives you true and it doesn't goes in the if statement?
yes. seems to have been a glitch on my device. I restarted my phone and its working now
