ReactNative:如何将文本居中?

如何在ReactNative中水平和垂直居中放置文本?

我在rnplay.org中有一个示例应用程序,其中 和 不起作用:https :

**//rnplay.org/apps/AoxNKQ**

文本应居中。为什么在文本(黄色)和父容器之间的顶部留有空白?

码:

'use strict';

var React = require('react-native');

var {

AppRegistry,

StyleSheet,

Text,

Image,

View,

} = React;

var SampleApp = React.createClass({

render: function() {

return (

<View style={styles.container}>

<View style={styles.topBox}>

<Text style={styles.headline}>lorem ipsum{'\n'}ipsum lorem lorem</Text>

</View>

<View style={styles.otherContainer}>

</View>

</View>

);

}

});

var styles = StyleSheet.create({

container: {

flex: 1,

flexDirection: 'column',

backgroundColor: 'red',

justifyContent: 'center',

alignItems: 'center',

},

topBox: {

flex: 1,

flexDirection: 'row',

backgroundColor: 'lightgray',

justifyContent: 'center',

alignItems: 'center',

},

headline: {

fontWeight: 'bold',

fontSize: 18,

marginTop: 0,

width: 200,

height: 80,

backgroundColor: 'yellow',

justifyContent: 'center',

alignItems: 'center',

},

otherContainer: {

flex: 4,

justifyContent: 'center',

alignItems: 'center',

backgroundColor: 'green',

},

});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

module.exports = SampleApp;

回答:

headline‘样式删除heightjustifyContentalignItems。它将使文本垂直居中。添加textAlign:

'center',它将使文本水平居中。

  headline: {

textAlign: 'center', // <-- the magic

fontWeight: 'bold',

fontSize: 18,

marginTop: 0,

width: 200,

backgroundColor: 'yellow',

}
