Is there anyway to compare s to a? In this code I have int s as the answer and if the drawable == s
then I want to display a \"Correct!\"

Comparing a Drawable
instance to an int
doesn't make sense. What are you trying to do? Do you want to check if the method res.getDrawable(R.drawable.exitbtn);
returns the right object?
I think it's redundant to fetch an identifier from R-file:
int s = R.drawable.exitbtn;
Then fetch the object using the very same identifier:
Drawable drawable = res.getDrawable(R.drawable.exitbtn);
And then try to check whether it's really the right object by comparing ids.
I think that there's no place for mistake (specifically, confusion of an int value) when it comes to getting a Drawable by id. If you want to be sure the object has been created, check it against a null.
Drawable drawable = res.getDrawable(R.drawable.exitbtn);
if(drawable != null){
//do stuff
} else {
//handle the situation where there's no drawable
}
Also, I think there's no way to fetch an id from a Drawable object. The instance returned by getDrawable
does not contain such information.
Better yet, you can use the fact that getDrawable
can throw a NotFoundException
if the id is somehow wrong. Check the docs for details.
