import AppBar from '@material-ui/core/AppBar';
import Toolbar from '@material-ui/core/Toolbar';
import Button from '@material-ui/core/Button';

const useStyles = makeStyles((theme) => ({
  button: {
    // 在这里定义按钮的样式
    // 例如：backgroundColor: 'red', color: 'white'
  },
}));

function MyAppBar() {
  const classes = useStyles();

  return (
    <AppBar position="static">
      <Toolbar>
        <Button className={classes.button}>按钮1</Button>
        <Button className={classes.button}>按钮2</Button>
