使用 i18n.System.setAppPreferredLanguage(language)

其中 language 可选值为:
https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-i18n-V5#getsystemlanguages9

具体代码如下:

import { TitleBar } from '@devwiki/common_ui';
import { i18n } from '@kit.LocalizationKit';

@Entry
@Component
struct SetLanguagePage {
  private readonly languageGroup = "languageGroup"
  @State selectedLanguage: string = 'zh-Hans';

  build() {
    Column() {
      TitleBar({
        title: $r('app.string.set_language_title')
      });
      Row() {
        Text('简体中文');
        Radio({ group: this.languageGroup, value: 'zh-Hans' }).checked(this.selectedLanguage == 'zh-Hans')
          .onChange(isChecked => {
            if (isChecked) {
              i18n.System.setAppPreferredLanguage('zh-Hans')
              this.selectedLanguage = 'zh-Hans'
            }
          });
      }

      Row() {
        Text('英文');
        Radio({ group: this.languageGroup, value: 'en-US' }).checked(this.selectedLanguage == 'en-US')
          .onChange(isChecked => {
            if (isChecked) {
              i18n.System.setAppPreferredLanguage('en-US')
              this.selectedLanguage = 'en-US'
            }
          });
      }
    }.width('100%').height('100%')
  }
}
