HarmonyOS 状态栏文字的颜色如何动态变化

1.参考设置沉浸式窗口的示例实现。2.设置窗口为全屏布局，配合设置导航栏、状态栏的透明度、背景/文字颜色及高亮图标等属性，与主窗口显示保持协调一致。

let isLayoutFullScreen = true;
      windowClass.setWindowLayoutFullScreen(isLayoutFullScreen, (err: BusinessError) => {
        let errCode: number = err.code;
        if (errCode) {
          console.error('Failed to set the window layout to full-screen mode. Cause:' + JSON.stringify(err));
          return;
        }
        console.info('Succeeded in setting the window layout to full-screen mode.');
      });
      let sysBarProps: window.SystemBarProperties = {
        statusBarColor: '#ff00ff',
        navigationBarColor: '#00ff00',
        statusBarContentColor: '#ffffff',
        navigationBarContentColor: '#ffffff'
      };
      windowClass.setWindowSystemBarProperties(sysBarProps, (err: BusinessError) => {
        let errCode: number = err.code;
        if (errCode) {
          console.error('Failed to set the system bar properties. Cause: ' + JSON.stringify(err));
          return;
        }
        console.info('Succeeded in setting the system bar properties.');
      });
    })
