注释@InjectView在Android Studio中导入Butterknife后无效?

Just came across butterknife recently. I added the line in my gradle(module : app) file: compile 'com.jakewharton:butterknife:7.0.1'

最近刚遇到黄油刀。我在我的gradle(模块:app)文件中添加了一行:编译'com.jakewharton:butterknife:7.0.1'

It synched without any errors. I'm able to import 'butterknife.Butterknife' to my class file where the imports usualyy go. But cant import butterknife.InjectView doesn't seem to be there? Any suggestions?

它同步没有任何错误。我能进口“黄油刀”。黄油刀，到我的类文件，进口通常去那里。但不能导入butterknife。InjectView似乎不存在?有什么建议吗?

The Butterknife 7.0.0 release included the breaking change of renaming of the annotation verbs. This is highlighted in the changelog and reflected in the website.

Butterknife 7.0.0发行版包含重命名注释谓词的破坏性更改。在changelog中突出显示了这一点，并反映在网站中。

Version 7.0.0 *(2015-06-27)*
----------------------------

 * `@Bind` replaces `@InjectView` and `@InjectViews`.
 * `ButterKnife.bind` and `ButterKnife.unbind` replaces `ButterKnife.inject` 
    and `ButterKnife.reset`, respectively.

A very good, and up-to-date, introduction to the usage is at http://jakewharton.github.io/butterknife/

关于这个用法的一个非常好的最新介绍是http://jakewharton.github.io/butterknife/

Here is the simplest usage:

下面是最简单的用法:

class ExampleActivity extends Activity {
  @Bind(R.id.title) TextView title;
  @Bind(R.id.subtitle) TextView subtitle;
  @Bind(R.id.footer) TextView footer;

  @Override public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.simple_activity);
    ButterKnife.bind(this);
    // TODO Use fields...
  }
}

Obviously @InjectView was replaced by @Bind.

显然，@InjectView被@Bind取代。

Furhtermore you have to call ButterKnife.bind(this); in your onCreate().

你必须叫它ButterKnife.bind(这个);在onCreate()。

@InjectView is no more available and is replaced by @BindView. We will have to import Butterknife dependencies to use the annotations. More on butter knife here :- http://jakewharton.github.io/butterknife/

@InjectView不再可用，取而代之的是@BindView。我们将不得不导入Butterknife依赖项来使用注释。更多关于黄油刀的信息请访问:http://jakewharton.github.io/butterknife/

@BindView annotation could be implemented as :-

@BindView注释可以实现为:-

@BindView(R.id.button_id)

Note that you will need to call ButterKnife.bind(this); from onCreate() method of the main activity to enable Butterknife annotations. An example on this implementation could be something like :-

注意，您需要调用ButterKnife.bind(这个);来自onCreate()方法的主要活动，以启用Butterknife注释。这个实现的一个例子可以是:-

public class MainActivity extends AppCompatibilityActivity{
    @BindView(R.id.editText_main_firstName)
    EditText firstName;
    @BindView(R.id.editText_main_lastName)
    EditText lastName;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Needs to be called to enable Butterknife annotations
        ButterKnife.bind(this);

    }
}
