reactjs - 如何将 MUI Accordion 的标题颜色更改为灰色？

Question

我是 React 的 Material-UI 新手。我有一个关于 MUI Accordion 的非常简单的问题。我有以下代码:

import React from "react";
import { makeStyles, withStyles } from "@material-ui/core/styles";
import Accordion from "@material-ui/core/Accordion";
import MuiAccordionSummary from "@material-ui/core/AccordionSummary";
import AccordionDetails from "@material-ui/core/AccordionDetails";
import Typography from "@material-ui/core/Typography";
import ExpandMoreIcon from "@material-ui/icons/ExpandMore";

const useStyles = makeStyles((theme) => ({
  root: {
    width: "100%"
  },
  heading: {
    fontSize: theme.typography.pxToRem(15),
    fontWeight: theme.typography.fontWeightRegular
  }
}));

const AccordionSummary = withStyles({
})(MuiAccordionSummary);

export default function SimpleAccordion() {
  const classes = useStyles();

  return (
    <div className={classes.root}>
      <Accordion
        defaultExpanded={true}
      >
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls="panel1a-content"
          id="panel1a-header"
        >
          <Typography className={classes.heading}>Accordion 1</Typography>
        </AccordionSummary>
        <AccordionDetails>
          <Typography>
            Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
            malesuada lacus ex, sit amet blandit leo lobortis eget.
          </Typography>
        </AccordionDetails>
      </Accordion>
      <Accordion
        defaultExpanded={true}
      >
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls="panel2a-content"
          id="panel2a-header"
        >
          <Typography className={classes.heading}>Accordion 2</Typography>
        </AccordionSummary>
        <AccordionDetails>
          <Typography>
            Lorem ipsum dolor sit amet, consectetur adipiscing elit. Suspendisse
            malesuada lacus ex, sit amet blandit leo lobortis eget.
          </Typography>
        </AccordionDetails>
      </Accordion>
    </div>
  );
}

看起来像:

我正在尝试将页眉的颜色更改为灰色。如何实现？

Answer 1

除非我遗漏了什么，只需更改 AccordionSummary 的背景颜色:

V5

<AccordionSummary
  sx={{
    backgroundColor: "gray"
  }}
>

V4

const useStyles = makeStyles({
  summary: {
    backgroundColor: 'gray',
  }
);

<AccordionSummary
  className={classes.summary}
>
