如何为EditText的虚拟键盘设置默认语言

Question

I'm wanted to know if there any way i could set the default language of the virtual keyboard of an EditText in Android ?

Every time i get focus on my EditText it opens the virtual keyboard with my native language instead of English.

I guess it something with the device settings, but if there is a way to program that in Android development that would be terrific.

LocaleHelper ” is the solution all you need. You just have to initialize locale on your application's main class. After that all your language changes will persist.

In application class make following changes:

    public class MainApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        LocaleHelper.onCreate(this, "en");
    }
}

LocalHelper.java will be:

public class LocaleHelper {

private static final String SELECTED_LANGUAGE = "Locale.Helper.Selected.Language";

public static void onCreate(Context context) {
    String lang = getPersistedData(context, Locale.getDefault().getLanguage());
    setLocale(context, lang);
}

public static void onCreate(Context context, String defaultLanguage) {
    String lang = getPersistedData(context, defaultLanguage);
    setLocale(context, lang);
}

public static String getLanguage(Context context) {
    return getPersistedData(context, Locale.getDefault().getLanguage());
}

public static void setLocale(Context context, String language) {
    persist(context, language);
    updateResources(context, language);
}

private static String getPersistedData(Context context, String defaultLanguage) {
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    return preferences.getString(SELECTED_LANGUAGE, defaultLanguage);
}

private static void persist(Context context, String language) {
    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences.Editor editor = preferences.edit();

    editor.putString(SELECTED_LANGUAGE, language);
    editor.apply();
}

private static void updateResources(Context context, String language) {
    Locale locale = new Locale(language);
    Locale.setDefault(locale);

    Resources resources = context.getResources();

    Configuration configuration = resources.getConfiguration();
    configuration.locale = locale;

    resources.updateConfiguration(configuration, resources.getDisplayMetrics());
}

}
