您需要使用Input Adornments。

例如：

// imports
import IconButton from "@material-ui/core/IconButton";
import InputAdornment from "@material-ui/core/InputAdornment";
import SearchIcon from "@material-ui/icons/Search";

// render

<TextField
  label="With normal TextField"
  InputProps={{
    endAdornment: (
      <InputAdornment>
        <IconButton>
          <SearchIcon />
        </IconButton>
      </InputAdornment>
    )
  }}
/>

这是一个演示：

const {
  TextField,
  InputAdornment,
  IconButton,
  SearchIcon,
  Icon
} = window['material-ui'];

class App extends React.Component {
  render() {
    return (
      <TextField
        label="With normal TextField"
        InputProps={{
          endAdornment: (
            <InputAdornment>
              <IconButton>
                <Icon>search</Icon>
              </IconButton>
            </InputAdornment>
          )
        }}
      />
    );
  }
}

ReactDOM.render(<App />, document.getElementById('root'));

<div id="root"></div>

您只需要导入 inputAdornment

import InputAdornment from '@material-ui/core/InputAdornment';

并像这样将 InputProps 添加到 textField

InputProps={{
  endAdornment: (
    <InputAdornment position="start">
      <SearchIcon />
    </InputAdornment>
   )
  }}

请找到随附的 img 以演示您所需的解决方案。

就我而言，我只使用了 IconButton

import {  TextField, IconButton } from '@material-ui/core';

import { SearchOutlined } from '@material-ui/icons';

我的例子：

             <TextField
                fullWidth
                id="standard-bare"
                variant="outlined"
                defaultValue="How can we help"
                InputProps={{
                  endAdornment: (
                    <IconButton>
                      <SearchOutlined />
                    </IconButton>
                  ),
                }}
              />
