Implementing if statement directly to Arraylist

Question

I am using RecyclerView and CardView. I want the sysytem to choose which ImageView to display by circumstances from the JSON. How should I do it? I implemented the if statement but it seems like the statement is not working. Could someone give me an advice. This is my first time writing a parsing program. I don't know much about it.

statusArrayList.add(new Status(R.drawable.ic_action_name,"keihin",
       (i1 == 0? R.drawable.common_google_signin_btn_icon_dark_focused:
            R.drawable.common_google_signin_btn_icon_dark_focused));

Thanks for the reply. It didn't work. – morimokuseijin Nov 11 '19 at 06:27
You original question was asking how to replace an if statement in your parameter. And now you changed your code with my answer and ask another question? – EricHo Nov 11 '19 at 09:30
Even if you found you have another question, you could have just edit it, there is no need to downvote – EricHo Nov 11 '19 at 09:31
I've edited this question because some guy said it is a duplicated question. The another question is completely different from this! And I didn't put the down vote! I repeat I didn't. Thanks for your advice. – morimokuseijin Nov 18 '19 at 06:42
By the way, this issue is not an issue of the if statement. I've changed some places to .equals but it does not function. I think there is an issue on the parsing part. Thanks for your advice. – morimokuseijin Nov 18 '19 at 06:53
