本机Android BottomSheet未出现在React Native中

Question

我正在用Java构建自定义组件，并试图在React Native中显示该组件，但是该组件没有出现。我一直在论坛和文档中寻找解决方案，但是找不到解决方案。我不确定这是本机方面还是React Native方面的问题。任何有关改进的帮助或建议都将受到高度赞赏。

底页视图

public class BottomSheetView extends NestedScrollView {

    private BottomSheetBehavior bSheetBehavior;

    public BottomSheetView(Context context) {
        super(context);
        init();
    }

    private void init() {
        inflate(getContext(), R.layout.bottom_sheet, this);
        CoordinatorLayout coordinaterLayout = findViewById(R.id.coordinate_layout);
        View bottomSheet = coordinaterLayout.findViewById(R.id.bottom_sheet_component);
        bSheetBehavior = BottomSheetBehavior.from(bottomSheet);
        bSheetBehavior.setHideable(false);
        bSheetBehavior.setPeekHeight((int) PixelUtil.toPixelFromDIP(200));
    }

    @Override
    protected void onLayout(boolean b, int i, int i1, int i2, int i3) {
    }
}

底表管理器

public class BottomSheetManager extends ViewGroupManager<BottomSheetView> {
    public static final String REACT_CLASS = "BottomSheet";

    private BottomSheetView bottomSheet;

    @Override
    public String getName() {
        return REACT_CLASS;
    }

    @Override
    protected BottomSheetView createViewInstance(ThemedReactContext reactContext) {
        return new BottomSheetView(reactContext);
    }
}

底表包

public class BottomSheetPackage implements ReactPackage {
    private Activity mActivity = null;

    BottomSheetPackage(Activity activity) {
        mActivity = activity;
    }

    public BottomSheetPackage() {
    }

    @Override
    public List<NativeModule> createNativeModules(ReactApplicationContext reactContext) {
        List<NativeModule> modules = Collections.emptyList();
        return modules;
    }

    @Override
    public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
        return Arrays.<ViewManager>asList(new BottomSheetManager());
    }
}

反应原生

class BottomSheet extends Component {
       render() {
           return (<BottomSheet style={{height: 200}}/>);
       }
}
