android 使用kotlin 实现点击更换全局语言(中日英切换)

public class CommonUtil {
 public static void configLanguage(Context mContext, String language) {
 Configuration config = mContext.getResources().getConfiguration();
 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
 if (language.equals("CHINESE")) {
 config.locale = Locale.SIMPLIFIED_CHINESE;
 } else if (language.equals("ENGLISH")) {
 config.locale = Locale.US;
 } else if(language.equals("JAPANESE")){
 config.locale = Locale.JAPAN;
 }else {
 config.locale = Locale.SIMPLIFIED_CHINESE;
 }
 } else {
 if (language.equals("CHINESE")) {
 config.locale = Locale.CHINESE;
 } else if (language.equals("ENGLISH")) {
 config.locale = Locale.ENGLISH;
 } else if (language.equals("JAPANESE")){
 config.locale = Locale.JAPAN;
 }else {
 config.locale = Locale.CHINESE;
 }
 }
 mContext.getResources().updateConfiguration(config, null);
 }
}

override fun onClick(v: View) {
 when(v.id){
 R.id.tvChinese->{
 CommonUtil.configLanguage(this,"CHINESE")
 startActivity<LanguageActivity>()
 }
 R.id.tvEnglish->{
 CommonUtil.configLanguage(this,"ENGLISH")
 startActivity<LanguageActivity>()
 }
 R.id.tvJan->{
 CommonUtil.configLanguage(this,"JAPANESE")
 startActivity<LanguageActivity>()
 }
 }
 }
