Avoid status bar overlap on all screens

问题:

I want all screens on my app to appear below the status bar on both iOS and Android, so I'd either have to add a StatusBar component or a paddingTop to all my screens.

Is there a way to do this globally? Where is the appropriate top level component to add the StatusBar in a Redux app? (e.g. which part of https://github.com/react-community/react-navigation/tree/master/examples/ReduxExample)?

回答1:

Step 1: Import Platform and StatusBar

import { Platform, StatusBar} from 'react-native';

Step 2: Add this style in parent View

paddingTop: Platform.OS === 'ios' ? 0 : StatusBar.currentHeight 

Full Code:

import React, { Component } from 'react';
    import {
      Text, View,
      Platform, StatusBar
    } from 'react-native';

    export default class App extends Component {
      render() {
        return (
          <View style={{ paddingTop: Platform.OS === 'ios' ? 0 : StatusBar.currentHeight }}>
            <Text>This is Text</Text>
          </View>
        );
      }
    }

You can create a <NavigationContainer/> component to hold all your different pages, so that you don't need to duplicate the StatusBar and padding code in every single screen component.

I created a example in here:　https://snack.expo.io/SyaCeMOwW

And nothing need to change in term of your navigation structure or redux flow.
