我目前正在react項目中實現Material-UI庫的Accordion組件:

我想做的是有手風琴摘要(標題與& quot手風琴1 & quot，& quot手風琴2 & quot)居中，展開圖標(箭頭)在右下方，也居中。

在Material-UI文檔(https://Material-UI . com/components/accordion/)中，顯示的布局如下所示:

使用以下代碼(如文檔中所示):

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Accordion from '@material-ui/core/Accordion';
import AccordionSummary 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,
  },
}));

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

  return (
    <div className={classes.root}>
      <Accordion>
        <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>
        <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>
      <Accordion disabled>
        <AccordionSummary
          expandIcon={<ExpandMoreIcon />}
          aria-controls="panel3a-content"
          id="panel3a-header"
        >
          <Typography className={classes.heading}>Disabled Accordion</Typography>
        </AccordionSummary>
      </Accordion>
    </div>
  );
}

謝謝大家！

將摘要內容的flex-grow從1更改為0似乎就足夠了:

import { withStyles } from "@material-ui/core/styles";
import MuiAccordionSummary from "@material-ui/core/AccordionSummary";
const AccordionSummary = withStyles({
  content: {
    flexGrow: 0
  }
})(MuiAccordionSummary);

如果您希望箭頭在摘要文本的下方居中(而不是像我的第一個例子中那樣在它旁邊)，那么您可以使用下面的代碼:

const AccordionSummary = withStyles({
  root: {
    flexDirection: "column"
  },
  content: {
    marginBottom: 0
  },
  expandIcon: {
    marginRight: 0,
    paddingTop: 0
  }
})(MuiAccordionSummary);

第二個示例還演示了如何使用SimpleAccordion的類(如注釋中所請求的那樣),使用withStyles而不是makeStyles/useStyles來實現示例中的附加樣式。
