我对RTL有一个奇怪的问题,即似乎TextInput
之外的所有内容都被正确翻转了-大约50%的时间都起作用。这是显示我在英语和希伯来语之间切换语言时出现的问题的gif:

这是我包裹着树的主题组件。
import React, {useContext} from 'react'
import {create} from 'jss'
import jssRtl from 'jss-rtl'
import JssProvider from 'react-jss/lib/JssProvider'
import {
createGenerateClassName,
jssPreset,
MuiThemeProvider,
createMuiTheme
} from '@material-ui/core/styles'
import CssBaseline from '@material-ui/core/CssBaseline'
import {UserContext} from 'src/context/user.js'
const generateClassName = createGenerateClassName()
const plugins = [...jssPreset().plugins]
const dir = locale => {
const base = locale.split('-') || []
return ['he', 'ar'].includes(base[0]) ? 'rtl' : 'ltr'
}
const setDir = dir => {
window.document &&
window.document.getElementsByTagName('body')[0].setAttribute('dir', dir)
}
export default function Theme({children}) {
const {locale} = useContext(UserContext)
const direction = dir(locale)
const theme = createMuiTheme({direction, useNextVariants: true})
if (direction === 'rtl') plugins.push(jssRtl())
setDir(direction)
console.log('theme', {locale, direction})
return (
<MuiThemeProvider theme={theme}>
<CssBaseline />
{direction === 'rtl' ? (
<JssProvider
jss={create({plugins})}
generateClassName={generateClassName}
>
{children}
</JssProvider>
) : (
children
)}
</MuiThemeProvider>
)
}

疯狂的猜测:尝试一次添加jssRtl
pugin。您正在jssRtl
组件的每个渲染上添加Theme
插件。这可能解释了它不可能在50%的时间内工作,因为每个偶数渲染都意味着翻转两次,这相当于不翻转。
