Question

我尝试在react native中使用textAlign：'justify'属性。TextAlign justify在Android上不起作用。 React本机版本：“ react-native”：“ 0.59.5”

import React from 'react';
import { Image, View } from 'react-native';
import { Text, Button } from 'native-base';
import { connect } from 'react-redux';
import EStyleSheet from 'react-native-extended-stylesheet';
import { colors } from '../styles';

class Login extends React.Component {
  render() {
    return (
        <View style={styles.container}>
            <View style={styles.contentCenter}>
                <Text style={[styles.titleContent,styles.fontBold]}>Simple Secure</Text>
                <Text style={[styles.titleContent,styles.fontBold]}>Reliable Messaging</Text>
            </View>
        </View>
    );
  }
}


const styles = EStyleSheet.create({
    titleContent: {
        color:'#62778c',
        fontSize: '1.4rem',
        textAlign: 'justify',
      }
});

const mapStateToProps = (state) => {
  return {};
};

export default connect(mapStateToProps)(Login);

Answer 1

签出offical document：

textAlign：enum（'auto'，'left'，'right'，'center'，'justify'）

指定文本对齐方式。值'justify'仅在iOS上受支持，后备广告在Android上向左退回。

Answer 2

如上所述，android不支持文本对齐，但是您可以通过在WebView中添加html文本来解决此问题：

private PwmPin buzzerPin;
private PwmController pwmController;

public RainbowHAT()
{
    // ... do something else
    InitAsync();
}

private async void InitAsync()
{
    Logger.Log(this, "Init");

    // Setup PWM controller.
    if (LightningProvider.IsLightningEnabled)
    {
        LowLevelDevicesController.DefaultProvider = LightningProvider.GetAggregateProvider();
    }

    var pwmControllers = await PwmController.GetControllersAsync(LightningPwmProvider.GetPwmProvider());
    if (pwmControllers == null || pwmControllers.Count < 2)
    {
        throw new OperationCanceledException("Operation canceled due missing GPIO controller");
    }

    pwmController = pwmControllers[1];
    pwmController.SetDesiredFrequency(50);

    // Setup buzzer
    buzzerPin = pwmController.OpenPin(13); <-- CRASH
    buzzerPin.SetActiveDutyCyclePercentage(0.05);
    buzzerPin.Start();
}

textAlign justify属性在本机中不起作用
