harmonyOS开发技巧（二）——沉浸式以及状态栏高

1. 设置沉浸式：win.setWindowLayoutFullScreen(true);

2. 获取状态栏的高：win.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM)以及win.on('avoidAreaChange', (data) => {})。

import UIAbility from '@ohos.app.ability.UIAbility';
import window from '@ohos.window';
import { logger } from '@ohos/commonLib';

const TAG: string = 'EntryAbility';

export default class EntryAbility extends UIAbility {
  onCreate(want, launchParam) {
    logger.info(TAG, 'onCreate');
  }

  onDestroy() {
    logger.info(TAG, 'onDestroy');
  }

  onWindowStageCreate(windowStage: window.WindowStage) {
    windowStage.loadContent('pages/StartPage', (err, data) => {
      if (err.code) {
        logger.info(TAG, 'loadContent err=', JSON.stringify(err) ?? '');
        return;
      }
      logger.info(TAG, 'loadContent success=', JSON.stringify(data) ?? '');
    });
  }

  private setWindow(windowStage: window.WindowStage) {
    windowStage.getMainWindow().then((win: window.Window) => {
      win.setWindowLayoutFullScreen(true);
      try {
        const avoidArea = win.getWindowAvoidArea(window.AvoidAreaType.TYPE_SYSTEM);
        if (avoidArea) {
          // AppStorage.SetOrCreate('statusBarHeight', avoidArea?.topRect?.height);
        }
        win.on('avoidAreaChange', (data) => {
          // AppStorage.SetOrCreate('statusBarHeight', data?.area?.topRect?.height);
        });
      } catch (err) {

      }
    })
  }
}
