HarmonyOS resourceManager.getStringSync如何国际化？

参考代码：

//index文件
import I18n from '@ohos.i18n';
import { common } from '@kit.AbilityKit';

@Component
@Entry
struct Index {
  status: number = 1
  context: common.UIAbilityContext = getContext(this) as common.UIAbilityContext

  changeLanguage() {
    try {
      let contextStr = this.context.resourceManager.getStringSync($r('app.string.Language_change').id)
      console.log("11" + contextStr)
    } catch (error) {
      let code = (error as BusinessError).code;
      let message = (error as BusinessError).message;
      console.error(`getStringSync failed, error code: ${code}, message: ${message}.`);
    }
  }

  aboutToAppear(): void {
    this.changeLanguage();
  }

  build() {
    Column() {
      Text($r('app.string.Language_change'))
      Button('改变语言')
        .onClick(() => {
          if (this.status == 0) {
            I18n.System.setAppPreferredLanguage('zh-Hans');
            this.status = 1
          } else {
            I18n.System.setAppPreferredLanguage('en-Latn-US');
            this.status = 0
          }
          setTimeout(() => {
            this.changeLanguage();
          }, 5000)
        })
    }
    .margin({
      top: 70
    })
  }
}

然后在resources目录下配置base/element/string.json文件en_US/element/string.json文件zh_US/element/string.json文件下配置对应的语言最后在IDE导航菜单Run/Edit Configurations/Installation Options/Keep Application Data勾选
