ButterKnife does not injects views for MyFragment

Question

Something is wrong with ButterKnife injection. Upon starting my app, I'm getting below error:

Looks like all ButterKnife's @InjectView types are correct, but still ButterKnife is unable to inject views for my new fragment.

My layout looks like this

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/swipe_refresh"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler"
        android:scrollbars="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout>

and my new fragment has this @InjectViews:

@InjectView(R.id.swipe_refresh) SwipeRefreshLayout swipeRefreshLayout;
@InjectView(R.id.recycler) RecyclerView list;

Can you try/catch the exception and call `e.getCause().printStackTrace()` and paste that? — Jake Wharton, Jan 24 '15 at 00:17

In a fragment you should use it in onCreateView(...)

View v = inflater.inflate(R.layout.meh, container, false);
ButterKnife.inject(this, v);

Apparently I had to check other ButterKnife's annotations like @OnItemClick. I've used it for a RecyclerView, which was causing that RuntimeException for me.

It also pays to watch any bindings you are injecting from within the injected view that throws the error.

In my instance I had a fragment foo that injected a view bar

// Foo.java
View v = inflater.inflate(R.layout.bar, container, false);
ButterKnife.inject(this, v);

This was throwing the described error. It turns out that in foo I was binding to an element in baz that I expected to find inside my injected view bar.

// Foo.java
@InjectView(R.id.baz)
TextView filterTextView;

Except I had a typo in 'baz' in the layout xml for bar

// bar.xml
<EditText
   android:id="@+id/bazz"
/>

And this caused Unable to inject views for...
