罗马尼亚语Locale未被识别？如何修复Android多语言配置问题

Hey there! Let's work through this Romanian language translation button problem you're facing. I've run into similar locale quirks before, so here's what you need to check and fix:

1. First, Double-Check Your Resource File Structure #

Make sure your Romanian translation files are in the correct directory:

• For general Romanian (no specific region), use res/values-ro/strings.xml
• For Romanian specific to Romania, use res/values-ro-rRO/strings.xml

Ensure every string key in these files matches exactly with your default values/strings.xml—even a tiny typo can break the translation loading.

2. Replace Locale.RO with a Properly Constructed Locale Instance #

The Locale.RO constant might not be reliably recognized across all Android versions. Instead, create the locale explicitly using the constructor mentioned in the earlier thread:

// Create Romanian (Romania) locale explicitly
Locale romanianLocale = new Locale("ro", "RO");

Then update your configuration code with version compatibility (since config.locale is deprecated on Android N+):

Configuration config = getResources().getConfiguration();

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    config.setLocale(romanianLocale);
    // For Android N and above, this is the recommended way to update config
    getResources().updateConfiguration(config, getResources().getDisplayMetrics());
} else {
    // Fallback for older versions
    config.locale = romanianLocale;
    getResources().updateConfiguration(config, getResources().getDisplayMetrics());
}

3. Verify the Locale is Applied Correctly #

Add a log statement right after setting the locale to confirm it's working:

Log.d("LocaleDebug", "Active Locale: " + getResources().getConfiguration().locale);

You should see ro_RO in your logcat if the locale was set successfully.

4. Bonus: Persist the Locale (If Needed) #

If you want the language setting to stick after app restarts, save the selected locale (e.g., "ro-RO") to SharedPreferences and apply it when your app launches (in your Application class or main activity's onCreate).

Give these steps a try—this should resolve the issue where your Romanian translation wasn't loading. Let me know if you hit any snags!
