(Android, Butterknife) Why isnt @Bind working in this?

EditText topTextInput;
    EditText bottomTextInput;
    Button button;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.top_section_fragment, container, false);

        topTextInput = (EditText) view.findViewById(R.id.topTextInput);
        bottomTextInput = (EditText) view.findViewById(R.id.bottomTextInput);
        button = (Button) view.findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                buttonClicked(v);
            }
        });

        return view;
    }

This seems to work. I was originally trying to use Butterknife to bind the components like so:

//Bind the components to variables
@Bind(R.id.topTextInput) EditText topTextInput;
@Bind(R.id.bottomTextInput) EditText bottomTextInput;
 @Bind(R.id.button) Button button;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.top_section_fragment, container, false);

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                buttonClicked(v);
            }
        });

        return view;
    }

This doesnt work. I get an android.view.InflateException: Error inflating class fragment.

Whats going on here? How can I use Butterknife properly in this code?

Hi orbyt,

In your onCreateView method you need to call ButterKnife.bind(this, view); It needs to be after you instantiate your view like so:

//Bind the components to variables
@Bind(R.id.topTextInput) EditText topTextInput;
@Bind(R.id.bottomTextInput) EditText bottomTextInput;
 @Bind(R.id.button) Button button;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.top_section_fragment, container, false);
        ButterKnife.bind(this, view);


        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                buttonClicked(v);
            }
        });

        return view;
    }

I hope this helps, if not let me know.
