Question

我正在将react-native-status-bar-alert与react-navigation结合使用。在最新版本的反应导航中，高度存在问题。当警报处于活动状态时，标题的高度太大。其他人遇到过这个问题并有解决方案吗？

Answer 1

我认为您应该使用一个插件：navigationbar-react-native

首先，如果您使用react-navigation，则应隐藏标题栏并使用自定义标题栏

export const RootStack = createStackNavigator(
  {
    Home: {
      screen: HomeComponent,
      navigationOptions: {
        header: null,
      },
    },
  },
  {
    initialRouteName: 'Home',
  }
);

1，安装软件包

npm i navigationbar-react-native --save

2，使用

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,Image,
  View, 
  TouchableOpacity,
} from 'react-native';
import NavigationBar from 'navigationbar-react-native';
 
const ComponentLeft = () => {
  return(
    <View style={{ flex: 1, alignItems: 'flex-start'}} >
       <TouchableOpacity style={ {justifyContent:'center', flexDirection: 'row'}}>
        <Image 
          source={require('./img/ic_back.png')}
          style={{ resizeMode: 'contain', width: 20, height: 20, alignSelf: 'center' }}
        />
        <Text style={{ color: 'white', }}>Back Home</Text>
      </TouchableOpacity>
    </View>
  );
};
 
const ComponentCenter = () => {
  return(
    <View style={{ flex: 1, }}>
       <Image
        source={require('./img/ic_logo.png')}
        style={{resizeMode: 'contain', width: 200, height: 35, alignSelf: 'center' }}
      />
    </View>
  );
};
 
const ComponentRight = () => {
  return(
    <View style={{ flex: 1, alignItems: 'flex-end', }}>
      <TouchableOpacity>
        <Text style={{ color: 'white', }}> Right </Text>
      </TouchableOpacity>
    </View>
  );
};
 
class App extends Component {
  render() {
    return (
      <View style={styles.container}>
        <NavigationBar 
          componentLeft     = { () =>  {<ComponentLeft />   }
          componentCenter   = { () =>  {<ComponentCenter /> }
          componentRight    = { () =>  {<ComponentRight />  }
          navigationBarStyle= {{ backgroundColor: ''#215e79'' }}
          statusBarStyle    = {{ barStyle: 'light-content', backgroundColor: '#215e79' }}
        />
      </View>
    );
  }
}
