title: Butterknife Fragment Button not working
body: <p>I have a Fragment that I am using Butterknife with. </p>
  
  <pre><code>public class FooFragment extends Fragment {
      @Override
      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
          View view = inflater.inflate(R.layout.foo, container, false);
  
          ButterKnife.inject(this, view);
  
          return view;
      }
  
      @OnClick(R.id.some_btn)
      public void someButtonOnClick() {
          // do something
      }
  }
  </code></pre>
  
  <p>However, the someButtonOnClick method is never called when the button is tapped on the screen.</p>
  
  <p>Thoughts on what I am doing wrong with the Butterknife framework?</p>
  
  <p>Here is the layout that is being used:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical"
      android:background="@color/White"&gt;
  
      &lt;LinearLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="horizontal"&gt;
  
          &lt;Button
              android:id="@+id/some_btn"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_weight="1"
              android:layout_margin="@dimen/xsmall_margin"
              android:background="@drawable/some_btn_selection" /&gt;
  
          &lt;Button
              android:id="@+id/some_other_btn"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_weight="1"
              android:layout_margin="@dimen/xsmall_margin"
              android:background="@drawable/some_other_btn_selection" /&gt;
      &lt;/LinearLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
