接着上篇react-native-navigation步步深入之导航篇
，这篇接着聊一下react-native-navigation的配置项。所有的配置项基本上就是下述这么多。

参数什么的都有了，接下里就是怎样在项目中引用，一般情况我会分成两种情况来设置，那种公共的例如tab一般是不会改变的，我就写在App.js里面，有一些，比图topBar有可能会涉及到变颜色或者button个数不一样，这种我就会写在各自的组件文件里面。
App.js
Navigation.startTabBasedApp({
tabs: [
{
label: '首页',
screen: 'app.HomeScreen', // this is a registered name for a screen
icon: require('./src/assets/images/nav1.png'),
selectedIcon: require('./src/assets/images/nav1_active.png'), // iOS only
title: '首页'
},
{
label: '客户管理',
screen: 'app.OfferScreen', // this is a registered name for a screen
icon: require('./src/assets/images/nav2.png'),
selectedIcon: require('./src/assets/images/nav2_active.png'), // iOS only
title: '客户管理'
},
{
label: '车险报价',
screen: 'app.CustomerScreen', // this is a registered name for a screen
icon: require('./src/assets/images/nav3.png'),
selectedIcon: require('./src/assets/images/nav3_active.png'), // iOS only
title: '车险报价'
},
{
label: '我的',
screen: 'app.MeScreen',
icon: require('./src/assets/images/nav4.png'),
selectedIcon: require('./src/assets/images/nav4_active.png'), // iOS only
title: '我的'
}
],
// add
appStyle: {
/*nav */
navBarBackgroundColor: '#FBFBFB',
navBarTextColor: '#999',
navBarTextFontSize: 16,
navBarTitleTextCentered: true,
topBarElevationShadowEnabled: false,
/*tab */
tabBarBackgroundColor:'#FBFBFB',
forceTitlesDisplay: true,
tabBarButtonColor: '#999',
tabBarSelectedButtonColor: '#DD4F43',
/*screen */
screenBackgroundColor: '#fff',
keepStyleAcrossPush: false,
navBarNoBorder: true,
topBarBorderColor: '#f5f5f5',
topBarBorderWidth: 1.5,
statusBarTextColorScheme: 'dark',
navBarCustomView: 'CustomButton'
}
});
最终结果如下：

可以看到每次点击tab的时候navbar都会有短暂的黑屏，并且状态栏还是黑不溜秋的，都android8了，真心不想看到这条黑色的，但是想尽各种方法都解决不了沉浸式状态栏，最后迫不得已只有把react-native-navigation的navbar隐藏起来，然后加上statusBar透明，自己写了个navbar组件，这样既没有黑屏也没有大黑条，当然，如果有小伙伴还有其他解决方式，请留言！
