Question

^在上面的演示中，您可以看到工作代码，无论如何都只是试图水平对齐单选按钮。

在Material-UI中有一种简单的方法吗？或者我必须设置自己的单选按钮，我可以在5分钟内完成。

import React from "react";
import PropTypes from "prop-types";
import { withStyles } from "@material-ui/core/styles";
import Radio from "@material-ui/core/Radio";
import RadioGroup from "@material-ui/core/RadioGroup";
import FormHelperText from "@material-ui/core/FormHelperText";
import FormControlLabel from "@material-ui/core/FormControlLabel";
import FormControl from "@material-ui/core/FormControl";
import FormLabel from "@material-ui/core/FormLabel";

const styles = theme => ({
  root: {
    display: "flex"
  },
  formControl: {
    float: "left",
    margin: theme.spacing.unit * 3
  },
  group: {
    margin: `${theme.spacing.unit}px 0`
  }
});

class RadioButtonsGroup extends React.Component {
  state = {
    value: "female"
  };

  handleChange = event => {
    this.setState({ value: event.target.value });
  };

  render() {
    const { classes } = this.props;

    return (
      <div className={classes.root}>
        <FormControl
          component="fieldset"
          required
          className={classes.formControl}
        >
          <FormLabel component="legend">Gender</FormLabel>
          <RadioGroup
            aria-label="gender"
            name="gender1"
            className={classes.group}
            value={this.state.value}
            onChange={this.handleChange}
          >
            <FormControlLabel
              value="female"
              control={<Radio />}
              label="Female"
            />
            <FormControlLabel value="male" control={<Radio />} label="Male" />
            <FormControlLabel value="other" control={<Radio />} label="Other" />
            <FormControlLabel
              value="disabled"
              disabled
              control={<Radio />}
              label="(Disabled option)"
            />
          </RadioGroup>
        </FormControl>
        <FormControl
          component="fieldset"
          required
          error
          className={classes.formControl}
        >
          <FormLabel component="legend">Gender</FormLabel>
          <RadioGroup
            aria-label="gender"
            name="gender2"
            className={classes.group}
            value={this.state.value}
            onChange={this.handleChange}
          >
            <FormControlLabel
              value="male"
              control={<Radio color="primary" />}
              label="Male"
            />
            <FormControlLabel
              value="female"
              control={<Radio color="primary" />}
              label="Female"
            />
            <FormControlLabel
              value="other"
              control={<Radio color="primary" />}
              label="Other"
            />
            <FormControlLabel
              value="disabled"
              disabled
              control={<Radio />}
              label="(Disabled option)"
            />
          </RadioGroup>
          <FormHelperText>You can display an error</FormHelperText>
        </FormControl>
      </div>
    );
  }
}

RadioButtonsGroup.propTypes = {
  classes: PropTypes.object.isRequired
};

export default withStyles(styles)(RadioButtonsGroup);

RadioGroup元素包含单选按钮。如果你想连续渲染它们，最简单的方法可能是使用flexbox行。

你可以看到我在上面的代码框中做了什么，但它就像添加group样式一样简单：

flexDirection: 'row',

这是有效的，因为Material-UI已经为组使用了flexbox样式。这也是它无法在那里添加float: 'left'的原因。

您还可以在论坛上设置display: 'inline-block'：

display: 'inline-block'

这也将实现行样式，但控制选项更少。

我不认为有一个＆＃34;本地人＆＃34;在材质UI中执行此操作的方法，您必须自己执行此操作。事实上，这是一个更好的方法。

RadioButtonsGroup.propTypes = {

export default withStyles(styles)(RadioButtonsGroup);
