Android kotlin library for change ui language in android application on runtime.

Add mavenCentral() to your repositories and include the dependency in your module build.gradle:

repositories { mavenCentral() } dependencies { implementation 'com.ninenox.kotlinlocalemanager:kotlin-locale-manager:1.0.1' } 

1. Create class and extend ApplicationLocale.

class App : ApplicationLocale() { } 

2. In AndroidManifest.xml

<application android:name=".App" ... /> 

3. In folder res add new locale.

values-th - strings.xml values-en - strings.xml 

4. In any Activity extend AppCompatActivityBase on it.

class MainActivity : AppCompatActivityBase() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) ... } } 

5. Call funtion setNewLocale("...") for set current language and refresh UI.

 setNewLocale(LocaleManager.LANGUAGE_ENGLISH) // ตัวอย่าง LocaleManager.LANGUAGE_ENGLISH, LocaleManager.LANGUAGE_THAI, ... 

6. Get current language code string. The value of language will be a lowercase language code such as "en" or "th", and it is recommended to access it via ApplicationLocale.localeManager?.language to use the locale manager that is shared throughout the app.

ApplicationLocale.localeManager?.language // "en" 

7. Get current Locale instance.

LocaleManager.getLocale(resources) will return the current Locale and can be used for country checks or locale-aware formatting.

val locale = LocaleManager.getLocale(resources) if (locale.country == "TH") { // ประเทศไทย } val dateFormat = java.text.DateFormat.getDateInstance(java.text.DateFormat.SHORT, locale) val formattedDate = dateFormat.format(java.util.Date())
