我用的是材料-ui@next

您应该使用

MenuItem

而不是

ListItem

。如上所述：

MenuItem

是带有一些附加样式的

ListItem

的包装器

其中一个附加样式是

selected

选项，您可以使用

selected

属性设置该选项：

<MenuItem button selected>
  <ListItemIcon>
    <FolderIcon />
  </ListItemIcon>
  <ListItemText primary="Archives" />
</MenuItem>

import React from 'react';
import PropTypes from 'prop-types';
import { withStyles } from 'material-ui/styles';
import List, { ListItemIcon, ListItemText } from 'material-ui/List';
import { MenuItem } from 'material-ui/Menu';
import InboxIcon from 'material-ui-icons/Inbox';
import DraftsIcon from 'material-ui-icons/Drafts';
import FolderIcon from 'material-ui-icons/Folder';

const styles = theme => ({
  root: {
    width: '100%',
    maxWidth: 360,
    backgroundColor: theme.palette.background.paper,
  },
});

class SimpleList extends React.Component {
  constructor(props) {
    super(props);

    this.state = { selected: null };
  }

  updateSelected(selectedIndex) {
    this.setState({ selected: selectedIndex });
  }

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

    return (
      <div className={classes.root}>
        <List>
          <MenuItem button onClick={() => this.updateSelected(0)} selected={selected === 0}>
            <ListItemIcon>
              <InboxIcon />
            </ListItemIcon>
            <ListItemText primary="Inbox" />
          </MenuItem>
          <MenuItem button onClick={() => this.updateSelected(1)} selected={selected === 1}>
            <ListItemIcon>
              <DraftsIcon />
            </ListItemIcon>
            <ListItemText primary="Drafts" />
          </MenuItem>
          <MenuItem button onClick={() => this.updateSelected(2)} selected={selected === 2}>
            <ListItemIcon>
              <FolderIcon />
            </ListItemIcon>
            <ListItemText primary="Archives" />
          </MenuItem>
        </List>
      </div>
    );
  }
}

SimpleList.propTypes = {
  classes: PropTypes.object.isRequired,
};

export default withStyles(styles)(SimpleList);
