Question

我尝试在我的应用程序中使用两种语言。我的项目中有不同的string.xml文件。我试着像这样改变语言

like

我在按钮onClick

中使用我的课程

public class LocaleManager {

public static final String LANGUAGE_ENGLISH   = "en";
public static final String LANGUAGE_GEORGIAN = "ka";
private static final String LANGUAGE_KEY       = "language_key";

public static Context setLocale(Context c) {
    return updateResources(c, getLanguage(c));
}

public static Context setNewLocale(Context c, String language) {
    persistLanguage(c, language);
    return updateResources(c, language);
}

public static String getLanguage(Context c) {
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(c);
    return prefs.getString(LANGUAGE_KEY, LANGUAGE_ENGLISH);
}

@SuppressLint("ApplySharedPref")
private static void persistLanguage(Context c, String language) {
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(c);

    prefs.edit().putString(LANGUAGE_KEY, language).commit();
}

private static Context updateResources(Context context, String language) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        Resources resources = context.getResources();
        Configuration configuration = resources.getConfiguration();
        configuration.setLocale(new Locale(language));
        context.getApplicationContext().createConfigurationContext(configuration);
    } else {
        Locale locale = new Locale(language);
        Locale.setDefault(locale);
        Configuration config = context.getResources().getConfiguration();
        config.locale = locale;
        context.getResources().updateConfiguration(config,
                context.getResources().getDisplayMetrics());
    }
    return context;
}

public static Locale getLocale(Resources res) {
    Configuration config = res.getConfiguration();
    return Build.VERSION.SDK_INT >= 24 ? config.getLocales().get(0) : config.locale;
}

我有两个问题：

1）我测试了它并且语言环境正在成功更改，但我无法更改flagImg.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { if (!LocaleManager.getLanguage(LauncherActivity.this).equals(LocaleManager.LANGUAGE_ENGLISH)) LocaleManager.setNewLocale(LauncherActivity.this, LocaleManager.LANGUAGE_ENGLISH); else LocaleManager.setNewLocale(LauncherActivity.this, LocaleManager.LANGUAGE_GEORGIAN); Intent i = new Intent(LauncherActivity.this, LauncherActivity.class); startActivity(i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK)); overridePendingTransition(R.anim.fade_in_dialog, R.anim.fade_out_dialog); } });。是否可以在不刷新setText的情况下更改setText？

2）语言环境发生变化后，我尝试在activity方法中使用我的setText，但仍然无法更改

我如何解决这个问题？

Locale更改后无法更改文本
