【问题描述】：

在更新到 React Native 0.18 后尝试让模块工作时出现以下错误：

com.lwansbrough.RCTCamera.RCTCameraViewManager 无法转换为 com.facebook.react.uimanager.ViewGroupmanager

导致此类错误的原因是什么，如何解决？

这是 RCTCameraViewManager 的代码：

package com.lwansbrough.RCTCamera;

import android.support.annotation.Nullable;
import com.facebook.react.uimanager.*;

public class RCTCameraViewManager extends SimpleViewManager<RCTCameraView> 
    private static final String REACT_CLASS = "RCTCameraView";

    @Override
    public String getName() 
        return REACT_CLASS;
    

    @Override
    public RCTCameraView createViewInstance(ThemedReactContext context) 
        return new RCTCameraView(context);
    

    @ReactProp(name = "aspect")
    public void setAspect(RCTCameraView view, int aspect) 
        view.setAspect(aspect);
    

    @ReactProp(name = "captureMode")
    public void setCaptureMode(RCTCameraView view, int captureMode) 
        // TODO - implement video mode
    

    @ReactProp(name = "captureTarget")
    public void setCaptureTarget(RCTCameraView view, int captureTarget) 
        // No reason to handle this props value here since it's passed again to the RCTCameraModule capture method
    

    @ReactProp(name = "type")
    public void setType(RCTCameraView view, int type) 
        view.setCameraType(type);
    

    @ReactProp(name = "torchMode")
    public void setTorchMode(RCTCameraView view, int torchMode) 
        view.setTorchMode(torchMode);
    

    @ReactProp(name = "flashMode")
    public void setFlashMode(RCTCameraView view, int flashMode) 
        view.setFlashMode(flashMode);
    

    @ReactProp(name = "orientation")
    public void setOrientation(RCTCameraView view, int orientation) 
        view.setOrientation(orientation);
    

    @ReactProp(name = "captureAudio")
    public void setCaptureAudio(RCTCameraView view, boolean captureAudio) 
        // TODO - implement video mode
    

【参考方案1】：

我也遇到了这个错误，我的解决办法是改变

public class RCTCameraViewManager extends SimpleViewManager<RCTCameraView>

到

public class RCTCameraViewManager extends ViewGroupManager<RCTCameraView>
