Greenrobot Android Eventbus-无选项eventbusindex传递给注释处理器

我正在尝试使用Greenrobot的Eventbus在我的Android应用程序中设置一个简单的订户，但是我得到了一个gradle构建错误。我在下面展示了我的代码

事件类

public final class OffersProcessedEvent {}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support:design:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.facebook.android:facebook-android-sdk:4.5.0'
    compile 'com.jakewharton:butterknife:8.6.0'
    compile 'com.jakewharton:butterknife-compiler:8.6.0'
    compile 'com.jakewharton:butterknife:8.7.0'
    compile 'com.jakewharton:butterknife-compiler:8.7.0'

    compile 'org.greenrobot:eventbus-annotation-processor:3.0.1'
}

碱基片段

public class BaseFragment extends Fragment {
    private boolean registered;

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        EventBus.getDefault().register(this);
        registered = true;
   }

    @Override
    public void onResume() {
        super.onResume();
        if (!registered) {
        EventBus.getDefault().register(this);
        registered = true;
    }
}

    @Override
    public void onPause() {
        super.onPause();
        EventBus.getDefault().unregister(this);
        registered = false;
    }

    public AppCompatActivity getAppCompatActivity() {
        return (AppCompatActivity) getActivity();
    }
}

dependencies {
//other codes

kapt {
    arguments {
        arg('eventBusIndex', 'com.example.myapp.MyEventBusIndex')
    }
}

dependencies {
//other codes
}

apt {
    arguments {
        eventBusIndex "com.example.myapp.MyEventBusIndex"
    }
}

事件日志'

EventBus.getDefault().post(new OffersProcessedEvent());

订阅代码

@Subscribe
    public void onMessageEvent(OffersProcessedEvent event){
        *do whatever*
    }

以下是我的错误

基于此链接

当您设置构建脚本，并且没有添加任何 代码的注释尚未完成。没有任何@Subscribe注释， 将不会触发用于索引的批注处理器以使用 “eventBusIndex”选项。所以，只需添加一些@Subscribe注释和 你应该没事的

所以你必须补充一点

@Subscribe
fun onEvent(event: SomeEvent) {

}

但是您是否得到

错误：没有选项eventBusIndex传递给注释处理器

将此添加到你的

应用程序。gradle

如果使用注释处理器

defaultConfig {
    //other code

   javaCompileOptions {
       annotationProcessorOptions {
           arguments = [eventBusIndex: "com.example.myapp.MyEventBusIndex"]
       }
   }
}

如果使用kapt

public class BaseFragment extends Fragment {
    private boolean registered;

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        EventBus.getDefault().register(this);
        registered = true;
   }

    @Override
    public void onResume() {
        super.onResume();
        if (!registered) {
        EventBus.getDefault().register(this);
        registered = true;
    }
}

    @Override
    public void onPause() {
        super.onPause();
        EventBus.getDefault().unregister(this);
        registered = false;
    }

    public AppCompatActivity getAppCompatActivity() {
        return (AppCompatActivity) getActivity();
    }
}

dependencies {
//other codes
}
kapt {
    arguments {
        arg('eventBusIndex', 'com.example.myapp.MyEventBusIndex')
    }
}

dependencies {
//other codes
}

apt {
    arguments {
        eventBusIndex "com.example.myapp.MyEventBusIndex"
    }
}

如果使用安卓apt

public class BaseFragment extends Fragment {
    private boolean registered;

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        EventBus.getDefault().register(this);
        registered = true;
   }

    @Override
    public void onResume() {
        super.onResume();
        if (!registered) {
        EventBus.getDefault().register(this);
        registered = true;
    }
}

    @Override
    public void onPause() {
        super.onPause();
        EventBus.getDefault().unregister(this);
        registered = false;
    }

    public AppCompatActivity getAppCompatActivity() {
        return (AppCompatActivity) getActivity();
    }
}

dependencies {
//other codes
}
kapt {
    arguments {
        arg('eventBusIndex', 'com.example.myapp.MyEventBusIndex')
    }
}

dependencies {
//other codes
}

apt {
    arguments {
        eventBusIndex "com.example.myapp.MyEventBusIndex"
    }
}

此文件将由EventBus生成

/** This class is generated by EventBus, do not edit. */
public class MyEventBusIndex implements SubscriberInfoIndex {
    private static final Map<Class<?>, SubscriberInfo> SUBSCRIBER_INDEX;

    static {
        SUBSCRIBER_INDEX = new HashMap<Class<?>, SubscriberInfo>();

        putIndex(new SimpleSubscriberInfo(MainActivity.class, true, new SubscriberMethodInfo[] {
            new SubscriberMethodInfo("onBleClick", com.example.myapp.Events.BleClickListener.class),
        }));

    }

    private static void putIndex(SubscriberInfo info) {
        SUBSCRIBER_INDEX.put(info.getSubscriberClass(), info);
    }

    @Override
    public SubscriberInfo getSubscriberInfo(Class<?> subscriberClass) {
        SubscriberInfo info = SUBSCRIBER_INDEX.get(subscriberClass);
        if (info != null) {
            return info;
        } else {
            return null;
        }
    }
}

/**此类由EventBus生成，请勿编辑*/
公共类MyEventBusIndex实现SubscriberInfo索引{
私有静态最终地图，SubscriberInfo>（）；
putIndex（新SimpleSubscriberInfo（MainActivity.class，true，新SubscriberMethodInfo[]{
新SubscriberMethodInfo（“onBleClick”，com.example.myapp.Events.BleClickListener.class），
}));
}
专用静态索引（SubscriberInfo信息）{
订户索引put（info.getSubscriberClass（），info）；
}
@凌驾
公共SubscriberInfo getSubscriberInfo（类subscriberClass）{
SubscriberInfo=SUBSCRIBER_INDEX.get（subscriberClass）；
如果（信息！=null）{
退货信息；
}否则{
返回null；
}
}
}
