ActivityIndicator 活动指示器

规则

• 不要让活动指示器静止，用户会以为该任务停滞了。

• 在某些特定场景下，提供有意义的文案，帮助用户明白哪个任务正在进行中，eg：正在上传照片。

• 如果能知道用户的等待时间，可以使用组件 Progress 来替代。

代码演示

基本

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      animating: false,
    };
  }
  componentWillUnmount() {
    clearTimeout(this.closeTimer);
  }
  showToast = () => {
    this.setState({ animating: !this.state.animating });
    this.closeTimer = setTimeout(() => {
      this.setState({ animating: !this.state.animating });
    }, 1000);
  }
  render() {
    return (
      <div>
        <WingBlank>
          <div className="loading-container">
            <p className="sub-title">Without text</p>
            <div className="loading-example">
