How to Use ButterKnife.bind() in a non activity class #694

Closed kaustav07 closed 8 years ago

kaustav07 commented 8 years ago

I am using a class that implements TextWatcher to validate my fields in Sign up page and i want to use butterknife to bind views. How can i do it. I have passed the instance of my Activity class to my TextWatcher implementation but after that also it doesn't bind the views..What can i do?

butterknife

And the call from Activity

butterknife2

JakeWharton commented 8 years ago

Use the two argument version which separates the instance being bound (this) from the source of the views (activity).

kaustav07 commented 8 years ago

In my code how to do that?Can you guide please?

egor-n commented 8 years ago

Call ButterKnife.bind(this, this.activity) instead of ButterKnife.bind(this.activity) in the SignUpValidation. The first argument is the target for your bindings, the second argument is the source of the bindings.

It worked fine..Thank you very much..

Sorry for resurfacing this old thread, but in the new version of ButterKnife, there is now the ability to bind resources, such as with @BindColor() - is this possible to do in a custom view as long as I have a context object. I know I can pass along my activity reference, but I'd just rather not add an unnecessary extra parameter.

Yes. Reference the generated class directly and it has a constructor that accepts only a Context.

Hi @JakeWharton thanks for the quick reply. I'm not sure what you mean by the generated class. Which class should I be looking at because ButterKnife.bind doesn't have a signature that accepts only a Context:
