ButterKnife 注射有问题。启动我的应用程序后，出现以下错误：

看起来所有 ButterKnife 的 @InjectView 类型都是正确的，但 ButterKnife 仍然无法为我的新片段注入视图。

我的布局看起来像这样

<?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>

我的新片段有这个@InjectViews：

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

在片段中，您应该在 onCreateView(...) 中使用它

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

显然我必须检查其他 ButterKnife 的注释，例如@OnItemClick. 我已经将它用于 RecyclerView，这导致了我的 RuntimeException。

观察您从引发错误的注入视图中注入的任何绑定也是值得的。

在我的例子中，我有一个片段foo，它注入了一个视图栏

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

这是抛出所描述的错误。事实证明，在foo中，我绑定到baz中的一个元素，我希望在注入的 view bar中找到该元素。 

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

除了我在bar的布局 xml 中的“baz”中有错字

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

而这导致Unable to inject views for...
