Butterknife: What is the corrent way to unbind views in onDestroyView()

[meness]

Hi,

Previously I was using unbind() method but now in v8 of ButterKnife, there's no such method and just the binding method returns an Unbinder which will help with that. But the question, what is the correct way to do that? Is it recommended in fragments?

[lkishor]

Create a field in your fragment as
Unbinder unbinder;
in onCreateView you call

unbinder = Butterknife.bind(this, root);

and in onDestroyView you need to call

unbinder.unbind();

thats it you're done.

@lkishor Thanks man. Is it recommended to unbind?

[lkishor]

Yes it is, It will set your bindings to null, freeing up memory...take a look at

@lkishor Thanks so much man.

Sorry to ask this, but why the change from the simple Butterknife.unbind()?

So listeners can be cleared

Is it really necessary that Butterknife throws an exception when the target object is null while unbinding (throw new IllegalStateException("Bindings already cleared."))? Could it not just do nothing? With the exception thrown I have to catch it always preventively and cannot do anything about it anyway.

I agree with @semaphore3000 . Is there a better way to handle this @JakeWharton
