在Android Studio中导入Butterknife后,注释@InjectView无法正常工作？

Question

刚刚遇到了奶油刀.我在gradle(module:app)文件中添加了这行:compile'c​​om.jakewharton:butterknife:7.0.1'

它同步没有任何错误.我可以将'butterknife.Butterknife'导入到我的类文件中,其中导入usualyy.但是无法导入butterknife.InjectView似乎没有？有什么建议？

Answer 1

Butterknife 7.0.0版本包括重命名注释动词的重大变化.这在更改日志中突出显示并反映在网站中.

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

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

http://jakewharton.github.io/butterknife/是一本非常好的,最新的用法介绍.

这是最简单的用法:

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...
  }
}

@InjectView不再可用，并由代替@BindView。我们将必须导入Butterknife依赖项才能使用注释。有关黄油刀的更多信息，请点击此处：-http : //jakewharton.github.io/butterknife/

@BindView 注释可以实现为：

@BindView(R.id.button_id)

请注意，您将需要ButterKnife.bind(this);从onCreate()main活动的方法调用来启用Butterknife批注。关于此实现的示例可能类似于：

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);

    }
}

如果您正在使用Butterknife片段，则使用Butterknife.bind(this,view)该视图作为片段视图，即：-

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