人力资源三网站建设网站权重如何查询

1.在res下创建多语言资源文件：

 2.选择需要的语言

然后得到多种语言适配string文件：

 

3.代码设置多语言

 

object LanguageHelper {/*** 获取适配的 Context*/fun getAttachBaseContext(context: Context): Context {return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {setAppLanguageApi24(context)} else {setAppLanguage(context)context}}/*** 获取当前系统语言，如未包含则默认中文*/private fun getSystemLocal(): Locale {val systemLocal = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {LocaleList.getDefault()[0]} else {Locale.getDefault()}return when (systemLocal.language) {Locale.CHINA.language -> Locale.CHINA // 简体中文Locale.TAIWAN.language -> Locale.TAIWAN // 台湾繁体"zh" -> when (systemLocal.country) { // 修复拼写错误"HK" -> Locale("zh", "HK") // 香港繁体else -> Locale.CHINA // 默认简体中文}Locale.ENGLISH.language -> Locale.ENGLISH // 英文else -> Locale.CHINA // 默认简体中文}}/*** 兼容 7.0 以上*/@TargetApi(Build.VERSION_CODES.N)private fun setAppLanguageApi24(context: Context): Context {val locale = getSystemLocal()val configuration = context.resources.configurationconfiguration.setLocale(locale)configuration.setLocales(LocaleList(locale))return context.createConfigurationContext(configuration)}/*** 动态更新 Context 的资源配置*/fun updateResources(context: Context, locale: Locale): Context {val resources = context.resourcesval configuration = resources.configurationif (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {configuration.setLocale(locale)configuration.setLocales(LocaleList(locale))return context.createConfigurationContext(configuration)} else {configuration.locale = localeresources.updateConfiguration(configuration, resources.displayMetrics)}return context}/*** 设置应用语言*/private fun setAppLanguage(context: Context) {val locale = getSystemLocal()updateResources(context, locale)}}

4.使用示例

 1.在 Application 中使用

在 Application 类的 attachBaseContext 方法中调用 LanguageHelper.getAttachBaseContext，以确保应用启动时使用正确的语言环境。

class MyApplication : Application() {override fun attachBaseContext(base: Context) {super.attachBaseContext(LanguageHelper.getAttachBaseContext(base))}
}

2. 在 Activity 中动态切换语言

在设置页面中，当用户选择语言后，调用 LanguageHelper.updateResources 方法更新当前 Activity 的资源配置，并刷新界面。

class SettingsActivity : AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_settings)// 假设有一个语言选择的下拉菜单val languageSpinner = findViewById<Spinner>(R.id.languageSpinner)val languages = arrayOf("简体中文", "繁體中文（台灣）", "繁體中文（香港）", "English")val adapter = ArrayAdapter(this, android.R.layout.simple_spinner_item, languages)languageSpinner.adapter = adapter// 监听语言选择languageSpinner.onItemSelectedListener = object : AdapterView.OnItemSelectedListener {override fun onItemSelected(parent: AdapterView<*>?, view: View?, position: Int, id: Long) {val selectedLanguage = languages[position]when (selectedLanguage) {"简体中文" -> setAppLanguage(Locale.CHINA)"繁體中文（台灣）" -> setAppLanguage(Locale.TAIWAN)"繁體中文（香港）" -> setAppLanguage(Locale("zh", "HK"))"English" -> setAppLanguage(Locale.ENGLISH)}}override fun onNothingSelected(parent: AdapterView<*>?) {}}}private fun setAppLanguage(locale: Locale) {// 更新应用语言LanguageHelper.updateResources(this, locale)recreate() // 刷新当前 Activity}
}
