javascript - React Material UI GridList 单元格不能正确换行

Question

使用 Material-UI GridList 时，单元格不会“正确”包裹在网格中。
在 css 中潜水时，我注意到它使用了 flex-wrap，它假设可以弯曲行，但我确信有一种方法可以使用这个组件，并且可以选择填充所有空格。
代码:

const useStyles = makeStyles((theme) => ({
root: {
  display: "flex",
  flexWrap: "wrap",
  justifyContent: "space-around",
  overflow: "hidden",
  backgroundColor: theme.palette.background.paper,
  paddingTop: theme.spacing(4),
},
gridList: {
  width: 500,
  height: '100%',
},
listItem: {
  borderRadius: theme.borderRadius['secondary'],
  overflow: "hidden",
},
}));

function Gallery(props) {
  const styles = useStyles();
  const cols = [
  [2, 2],
  [1, 2],
  [1, 2],
  [2, 1],
  [1, 1],
  [1, 1],
  [1, 1],
];

const renderItem = (tile, index) => (
  <GridListTile
    classes={{ root: styles.listItem }}
    key={tile.image}
    cols={cols[index % cols.length][0]}
    rows={cols[index % cols.length][1]}
  >
    <img src={tile.image} alt={tile.title} />
  </GridListTile>
);
return (
  <div className={styles.root}>
    <GridList
      cellHeight={160}
      className={styles.gridList}
      cols={3}
      spacing={10}
    >
      {data.items.map(renderItem)}
    </GridList>
  </div>
);
}

我很感激帮助

我引用了 MaterialUI 的文档
您同时指定了行和列。删除 rows={cols[index % cols.length][1]}解决了这个问题。
这是工作示例。 (图片取自sample)

import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import GridList from '@material-ui/core/GridList';
import GridListTile from '@material-ui/core/GridListTile';

const App = () => {
  const useStyles = makeStyles((theme) => ({
    root: {
      display: 'flex',
      flexWrap: 'wrap',
      justifyContent: 'space-around',
      overflow: 'hidden',
      backgroundColor: theme.palette.background.paper,
      paddingTop: theme.spacing(4),
    },
    gridList: {
      width: 500,
      height: '100%',
    },
    listItem: {
      overflow: 'hidden',
    },
  }));

  const styles = useStyles();
  const cols = [
    [2, 2],
    [1, 2],
    [1, 2],
    [2, 1],
    [1, 1],
    [1, 1],
    [1, 1],
  ];

  const tileData = [
    {
      img: '/static/images/grid-list/breakfast.jpg',
      title: 'Breakfast',
      author: 'jill111',
      cols: 2,
      featured: true,
    },
    {

    {
      img: '/static/images/grid-list/vegetables.jpg',
      title: 'Vegetables',

      cols: 2,

    {

    {

    {
      img: '/static/images/grid-list/bike.jpg',
      title: 'Bike',
      author: 'danfador',
    },
  ];

  const renderItem = (tile, index) => (
    <GridListTile
      classes={{ root: styles.listItem }}
      key={tile.image}
      cols={cols[index % cols.length][0]}
    >
      <img src={tile.img} alt={tile.title} />
    </GridListTile>
  );
  return (
    <div className={styles.root}>
      <GridList
        cellHeight={160}
        className={styles.gridList}
        cols={3}
        spacing={10}
      >
        {tileData.map(renderItem)}
      </GridList>
    </div>
  );
};

export default App;
