## zh-CN
对于字符型的头像,当字符串较长时,字体大小可以根据头像宽度自动调整。
## en-US
For letter type Avatar, when the letters are too long to display, the font size can be automatically adjusted according to the width of the Avatar.
```tsx
import React, { useState } from 'react';
import { Avatar, Button } from 'antd';
const UserList = ['U', 'Lucy', 'Tom', 'Edward'];
const ColorList = ['#f56a00', '#7265e6', '#ffbf00', '#00a2ae'];
const Autoset: React.FC = () => {
const [user, setUser] = useState(UserList[0]);
const [color, setColor] = useState(ColorList[0]);
const changeUser = () => {
const index = UserList.indexOf(user);
setUser(index < UserList.length - 1 ? UserList[index + 1] : UserList[0]);
setColor(index < ColorList.length - 1 ? ColorList[index + 1] : ColorList[0]);
};
return (
<>
<Avatar style={{ backgroundColor: color, verticalAlign: 'middle' }} size="large">
{user}
</Avatar>
<Button
size="small"
style={{ margin: '0 16px', verticalAlign: 'middle' }}
onClick={changeUser}
>
Change
</Button>
</>
);
};
ReactDOM.render(<Autoset />, mountNode);
```
