HarmonyOS 鸿蒙Next状态栏

在EntryAbility.ets中的onWindowStageCreate()中加入以下代码：

let windowClass: window.Window = null;
windowStage.getMainWindow((err, data) => {  //获取主窗口
  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.setWindowLayoutFullScreen(true);  //设为全屏
  //显示状态栏, 'navigation' 如需显示导航栏，加入到下面数组中
  windowClass.setWindowSystemBarEnable(['status'], (err) => {
    if (err.code) {
      console.error('Failed to set the system bar to be visible. Cause:' + JSON.stringify(err));
      return;
    }
    console.info('Succeeded in setting the system bar to be visible.');
  });
})
