Inkinga enkulu ehlobene nokusabela kwendawo yomdabu ngokuphelele ukuthi kungaba nzima ukunquma isikhungo esiphelele sohlelo lokusebenza lwe-React Native. Lokhu kungaba yinkinga uma udinga ukusebenzisa lolu lwazi ukuze wenze izibalo noma udwebe izakhiwo.
import React, { Component } from 'react'; import { View, Text } from 'react-native'; class App extends Component { render() { return ( <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}> <Text>Hello World!</Text> </View> ); } } export default App;
Le khodi ingenisa ngaphandle imitapo yolwazi ethi React and React Native. Ikilasi Lohlelo Lokusebenza lizuza njengefa kusukela kusigaba Sengxenye, futhi indlela yokunikezela ibuyisela umbono ngokuthi “Sawubona Umhlaba!” umyalezo. Isigaba sohlelo lokusebenza siyathunyelwa ukuze sisetshenziswe kwamanye amafayela.
Qondanisa Ukubuka Okumiswe Okuphelele phakathi nendawo kwesokunxele/kwesokudla
Ayikho impendulo eqondile yalo mbuzo njengoba incike esimweni esithile sokusetshenziswa. Ngokuvamile, ukuqondanisa umbono omiswe ngokuphelele phakathi nendawo kwesokunxele noma kwesokudla kungenziwa ngokusebenzisa isakhiwo se-alignToCenter.
I-Flexbox

Ukuze usebenzise i-Flexbox kuhlelo lwakho lokusebenza lwe-React Native, udinga kuqala ukufaka imojuli ye-flex-packager. Bese, ungasebenzisa isici se-flexbox ukuze ucacise ukuthi uhlelo lwakho lokusebenza kufanele luziphathe kanjani uma luboniswa kudivayisi enosayizi wesikrini omncane noma omkhulu:
ngenisa {FlexBox } kusuka 'ku-react-native'; const App = () => (
Uma ufuna ukukhubaza i-Flexbox ngokuphelele, ungasebenzisa isici esingaguquki:
ngenisa {FlexBox } kusuka 'ku-react-native'; const App = () => (
