ReactNative: how to center text?

How to center Text in ReactNative both in horizontal and vertical?

I have an example application in rnplay.org where justifyContent="center" and alignItems="center" is not working: https://rnplay.org/apps/AoxNKQ

The text should being centered. And why is there a margin at the top between the text (yellow) and parent container?

Code:

'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;

If you're running into this issue on Android, like I was, make sure to set includeFontPadding to false (documentation).

In many instances, ReactNative supports CSS style properties, names as camelCase instead of the standard CSS dasherized-lisp-style (aka kebab-case)

Which is the same as React/JSX.

The CSS property text-align has the direct equivalent: textAlign

So usually, it's worth trying the CSS property, converted to camelCase.

The following property can be used: {{alignItems: 'center'}} becaus you are using item <Text> not "string".

<View style={{alignItems: 'center'}}>
 <Text> Hello i'm centered text</Text>
</View>

Okey , so its a basic problem , dont worry about this just write the <View> component and wrap it around the <Text> component

<View style={{alignItems: 'center'}}>
<Text> Write your Text Here</Text>
</View>

alignitems:center is a prop use to center items on crossaxis

justifycontent:'center' is a prop use to center items on mainaxis

You can use two approaches for this...

  1. To make text align center horizontally, apply this Property (textAlign:"center"). Now to make the text align vertically, first check direction of flex. If flexDirection is column apply property (justifyContent:"center") and if flexDirection is row is row apply property (alignItems : "center") .

  2. To Make text align center apply same property (textAlign:"center"). Now to make it align vertically make the hieght of the <Text> </Text> equal to view and then apply property (textAlignVertical: "center")...

Most Probably it will Work...

Simple add 

textAlign: "center"

in your styleSheet, that's it. Hope this would help.

edit: "center"

Wherever you have Text component in your page just you need to set style of the Text component.

 <Text style={{ textAlign: 'center' }}> Text here </Text>

you don't need to add any other styling property, this is spectacular magic it will set you text in center of the your UI.

Already answered but I'd like to add a bit more on the topic and different ways to do it depending on your use case.

You can add adjustsFontSizeToFit={true} (currently undocumented) to Text Component to auto adjust the size inside a parent node. 

  <Text adjustsFontSizeToFit={true} numberOfLines={1}>Hiiiz</Text>

You can also add the following in your Text Component:

<Text style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>

Or you can add the following into the parent of the Text component:

<View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
     <Text>Hiiiz</Text>
</View>

or both

 <View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
     <Text style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>
</View>

or all three

 <View style={{flex:1,justifyContent: "center",alignItems: "center"}}>
     <Text adjustsFontSizeToFit={true} 
           numberOfLines={1} 
           style={{textAlignVertical: "center",textAlign: "center",}}>Hiiiz</Text>
</View>

It all depends on what you're doing. You can also checkout my full blog post on the topic

In addition to the use cases mentioned in the other answers:

To center text in the specific use case of a BottomTabNavigator, remember to set showIcon to false (even if you don't have icons in the TabNavigator). Otherwise the text will be pushed toward bottom of Tab.

For example:

const TabNavigator = createBottomTabNavigator({
  Home: HomeScreen,
  Settings: SettingsScreen
}, {
  tabBarOptions: {
    activeTintColor: 'white',
    inactiveTintColor: 'black',
    showIcon: false, //do this
    labelStyle: {
      fontSize: 20,
      textAlign: 'center',
    },
    tabStyle: {
      backgroundColor: 'grey',
      marginTop: 0,
      textAlign: 'center',
      justifyContent: 'center',
      textAlignVertical: "center"
    }
  }

From headline' style remove height, justifyContent and alignItems. It will center the text vertically. Add textAlign: 'center' and it will center the text horizontally.

  headline: {
    textAlign: 'center', // <-- the magic
    fontWeight: 'bold',
    fontSize: 18,
    marginTop: 0,
    width: 200,
    backgroundColor: 'yellow',
  }
