1.setWindowSystemBarEnable接口

• https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/reference/apis/js-apis-window.md#setwindowsystembarenable9

通过设置setWindowSystemBarEnable接口的names参数来控制导航栏、状态栏 的可见模式

• names参数设置为['navigation']，设置顶部状态栏不可见。
• names参数设置为['status']，设置底部导航栏不可见。
• names参数设置为空,即[]，设置底部导航栏、顶部状态栏都不可见

2.设置顶部状态栏不可见

src/main/ets/entryability/EntryAbility.ts中，names参数设置为 ['navigation']

onWindowStageCreate(windowStage: window.WindowStage) {
...
...
    let names: Array<'status' | 'navigation'> = ['navigation'];
    let windowClass = null;
    windowStage.getMainWindow((err, data) => {
    if (err.code) {
      console.error('Failed to obtain the main window. Cause: ' + JSON.stringify(err));
      return;
    }
    windowClass = data;
    console.info('Succeeded in obtaining the main window. Data: ' + JSON.stringify(data));
    windowClass.setWindowSystemBarEnable(names, (err) => {
      if (err.code) {
        console.error('Failed to set the system bar to be invisible. Cause:' + JSON.stringify(err));
        return;
      }
      console.info('Succeeded in setting the system bar to be invisible.');
    });
  });
...
...
}

    let names: Array<'status' | 'navigation'> = ['status'];
    let windowClass = null;
    windowStage.getMainWindow((err, data) => {
    if (err.code) {
      console.error('Failed to obtain the main window. Cause: ' + JSON.stringify(err));
      return;
    }
    windowClass = data;
    console.info('Succeeded in obtaining the main window. Data: ' + JSON.stringify(data));
    windowClass.setWindowSystemBarEnable(names, (err) => {
      if (err.code) {
        console.error('Failed to set the system bar to be invisible. Cause:' + JSON.stringify(err));
        return;
      }
      console.info('Succeeded in setting the system bar to be invisible.');
    });
  });

      return;

        return;
      }
      console.info('Succeeded in setting the system bar to be invisible.');
    });
