android - 设置状态栏时 View 隐藏

Question

我有一个组件，它有一个 flex: 1 View ，带有一个状态栏组件和一个子组件，当状态栏元素不存在时指示器显示，但是当我添加状态栏元素，指示器隐藏，请问如何在添加状态栏时显示指示器，是什么让它隐藏

随着 StatusBar(指示器隐藏)

没有 StatusBar(Indicator 显示)

代码

子组件(开启)

import {BoxShadow} from 'react-native-shadow';

export default class On extends Component {
render() {
    const shadowOpt = {
        width: Dimensions.get('window').width,
        height: Dimensions.get('window').height / 10,
        color: "#000",
        border: 10,
        opacity: '0.15',
        radius: 20,
        x: 0,
        y: 5,
    }
    const dimensions = Dimensions.get('window');
    const Height = (dimensions.height);
    const Width = dimensions.width;
    return (
        <View style={{flex: 1}}><View name="indicator" style={{flexDirection: 'row',}}>

父元素

export default class Parent extends Component {
constructor(props) {
    super(props);
    this.state = {

    };
}
render() {
        return (
            <View style={{flex: 1}}>
                <StatusBar backgroundColor='#EE8F62' translucent={true} barStyle='light-content'/><On/>
            </View>
        );

    }
}

我们在 android 上遇到了类似的问题，这就是我们的处理方式，也许这会帮助您找到更好的解决方案。

您需要创建一个const 并将状态栏大小指定为一个值。

const NAVBAR_HEIGHT = Platform.select({
  ios: { marginTop: 0 },
  android: { marginTop: window.height / 8 }
});

然后在样式部分应该添加这一行，

marginTop: NAVBAR_HEIGHT.marginTop

像这样，

const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: "#E7EBF0",
    marginTop: NAVBAR_HEIGHT.marginTop
  }
});

这就是我们为应用程序创建状态栏的方式，

<View style={styles.container}>
        {/* if ios status bar will be added to the screen */}
        {Platform.OS === "ios" ? (
          <Statusbar backgroundColor="#000000" barStyle="light-content" />
        ) : null}
</View>
