我试图显示一个对象,而不使用ARCore点击屏幕.在Google提供的ARCore Sceneform的基本示例中,您需要在检测到曲面后点击屏幕.

我想实现它,AR显示对象而不点击屏幕.

Anchor newAnchor;

    for (Plane plane : mSession.getAllTrackables(Plane.class)) {
        if (plane.getType() == Plane.Type.HORIZONTAL_UPWARD_FACING
                && plane.getTrackingState() == TrackingState.TRACKING)
        {
            newAnchor = plane.createAnchor(plane.getCenterPose());
            break;
        }
    }

我试过这个没有点击屏幕显示.

如果有人知道怎么做,请帮助我.提前致谢

大家好，我正在尝试在我的应用程序中添加 react-navigation-drawer，我正面临这个问题。每当我打开抽屉时，背景或背景都会变成不透明的黑色。我尝试添加背景颜色，但对我不起作用。这是我的侧边栏代码：-

import Icon from 'react-native-vector-icons/Entypo';
const { width, height } = Dimensions.get("window");
const window = Dimensions.get("window");
let h = window.height / 812;
let w = window.width / 375;
let p = (h + w) / 2;

export default class SideBar extends Component {
    constructor(props) {
        super(props)
        this.state = {
            refreshing: true,
            index: '',
        }
    }

    componentDidMount() {
        BackHandler.addEventListener("hardwareBackPress", () => this.hardwareBackPress);
    }

    componentWillUnmount() {
        BackHandler.removeEventListener("hardwareBackPress", () => this.hardwareBackPress);
    }

    hardwareBackPress() …
