测试一个新的react-native项目:react-native init

react-native run-android日志:

我想在 MyCustomModuleClass 中调用一个方法从另一个类扩展 ReactContextBaseJavaModule

自定义模块.java

public class MyCustomModule extends ReactContextBaseJavaModule {

  private ReactContext mReactContext;

  public MyCustomModule(ReactApplicationContext reactContext) {
    super(reactContext);
    mReactContext = reactContext;
  }

  @Override
  public String getName() {
    return "CustomModule";
  }


    private void sendEvent(String eventName, Object params) {
        mReactContext
            .getJSModule(DeviceEventManagerModule.RCTDeviceEventEmitter.class)
            .emit(eventName, params);
    }    
}

我正在尝试这个..

其他类.java

public class OtherClass extends AnotherClass {

    @Override
    protected void eventOccurred(Context context) {
        MyCustomModule RNC = new MyCustomModule(?);//-> Can't call without ReactContext
        RNC.sendEvent("CustomEvent", ObjectData); 
    }   
}

对不起，我对java一无所知，有人可以帮我吗？

有什么办法可以在 OtherClass 中获得 ReactContext？
