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:
从headline
‘样式删除height
,justifyContent
和alignItems
。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',
}
