区域转换不适用于产品口味

问题描述 投票：0回答：1

我的应用程序具有将应用程序langugae更改为英语，阿拉伯语或俄语的功能。此应用程序具有不同的产品风味，即Flavor1，Flavor2。每个风味应用程序都有这个选项将应用程序语言转换为英语，阿拉伯语，俄语。我已经分别在两种风格中放置了字符串文件，并且没有在主文件中放置任何字符串文件。但是当我从选项中更改语言时，它只是改变了从左到右的方向，但是字符串没有被翻译。

下面是字符串文件层次结构

     Flavor1 
      values
        strings.xml [Contains all english strings]
      values-ar
        strings.xml [Contains all arabic strings]
       values-ru
         strings.xml [Contains all russian strings]
     main 
      values
        Contains colors,dimens but no strings file
    Flavor2 
      values
        strings.xml [Contains all english strings]
      values-ar
        strings.xml [Contains all arabic strings]
       values-ru
         strings.xml [Contains all russian strings]

下面是SettingsFragment的代码，其中更改了应用程序语言。

public class SettingsFragment extends PreferenceFragmentCompat implements
        SharedPreferences.OnSharedPreferenceChangeListener, Preference.OnPreferenceChangeListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Log.e("OnCreate:", "Preference Fragment");
        LanguageLocale.getInstance().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getResources().getDisplayMetrics());
        getPreferenceScreen().getSharedPreferences().registerOnSharedPreferenceChangeListener(this);
    }

    @Override
    public void onResume() {
        LanguageLocale.getInstance().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getResources().getDisplayMetrics());
        Log.e("OnResume:", "Preference Fragment");
        super.onResume();
    }

    @Override
    public void onDestroy() {
        Log.e("OnDestroy:", "Preference Fragment");
        getPreferenceScreen().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this);
        super.onDestroy();
    }

    @Override
    public void onCreatePreferences(Bundle bundle, String s) {

        Log.e("OnCreatePreference:", "Preference Fragment");
        addPreferencesFromResource(R.xml.pref_include);
    }

    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String s) {
        Preference preference = findPreference(s);
        Log.e("PF", "In OnSharedPreferenceChanged");
        if (null != preference) {
            if (preference instanceof ListPreference) {
                String selectedlang = null;
                Log.e("Key: ", preference.getKey());

                sharedPreferences = PreferenceManager.getDefaultSharedPreferences(Objects.requireNonNull(getContext()));
                LanguageLocale.getInstance().setContext(getContext());
                LanguageLocale.getInstance().setResources(Objects.requireNonNull(getActivity()).getResources());
                LanguageLocale.getInstance().setConfiguration(LanguageLocale.getInstance().getResources().getConfiguration());
                String value = sharedPreferences.getString(preference.getKey(), null);

                assert value != null;
                if (value.equals(getString(R.string.TEXT_LABEL_ENGLISH))) {
                    ((ListPreference) preference).setDefaultValue(getContext().getResources().getString(R.string.TEXT_LABEL_ENGLISH));
                    LanguageLocale.getInstance().setLocale(new Locale("en"));
                    Locale.setDefault(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().setConfiguration(new Configuration());
                    LanguageLocale.getInstance().getConfiguration().setLocale(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().getContext().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getContext().getResources().getDisplayMetrics());
                } else if (value.equals(getString(R.string.TEXT_LABEL_RUSSIAN))) {
                    ((ListPreference) preference).setDefaultValue(getContext().getResources().getString(R.string.TEXT_LABEL_RUSSIAN));
                    LanguageLocale.getInstance().setLocale(new Locale("ru"));
                    Locale.setDefault(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().setConfiguration(new Configuration());
                    LanguageLocale.getInstance().getConfiguration().setLocale(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().getContext().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getContext().getResources().getDisplayMetrics());
                }

                // Arabic Language setting added internalization
                else if (value.equals(getString(R.string.TEXT_LABEL_ARABIC))) {
                    ((ListPreference) preference).setDefaultValue(getContext().getResources().getString(R.string.TEXT_LABEL_ARABIC));
                    LanguageLocale.getInstance().setLocale(new Locale("ar"));
                    Locale.setDefault(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().setConfiguration(new Configuration());
                    LanguageLocale.getInstance().getConfiguration().setLocale(LanguageLocale.getInstance().getLocale());
                    LanguageLocale.getInstance().getContext().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getContext().getResources().getDisplayMetrics());
                }
                preference.setSummary(value);
                getActivity().finish();
                setPreferenceSummary(preference, value);

            }

        }
    }

    @Override
    public boolean onPreferenceChange(Preference preference, Object o) {
        return true;
    }

    private void setPreferenceSummary(Preference preference, String value) {
        if (preference instanceof ListPreference) {
            ListPreference listPreference = (ListPreference) preference;
            listPreference.setSummary(value);
        }
    }

    @Override
    public void onDisplayPreferenceDialog(Preference preference) {
        try {
            if (preference.getKey().equalsIgnoreCase("password_dialog")) {
                startActivity(new Intent(getActivity(), ChangePassword.class));
            } else {
                super.onDisplayPreferenceDialog(preference);
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

    @Override
    public void onPause() {
        LanguageLocale.getInstance().getResources().updateConfiguration(LanguageLocale.getInstance().getConfiguration(), LanguageLocale.getInstance().getResources().getDisplayMetrics());
        Log.e("OnPause:", "Preference Fragment");
        super.onPause();
    }
}

下面是构建文件中的产品风格和源集定义

productFlavors {
        Flavor1 {

        }
        Flavor2 {}

    }
    sourceSets {
        main{
            java {
                srcDirs('src/Flavor1/java/src', 'src/Flavor2/java/src','src/main/java/src')
            }
            res {
                srcDirs('src/Flavor1/res/src', 'src/Flavor2/res/src','src/main/res/src')
            }
        }
        Syriatel {
            java {
                srcDirs('src/Flavor1/java/src', 'src/main/java/src')
            }
            res {
                srcDirs('src/Flavor1/res/src', 'src/main/res/src')
            }
        }
        FMFI {
            java {
                srcDirs('src/Flavor2/java/src', 'src/main/java/src')
            }
            res {
                srcDirs('src/Flavor2/res/src', 'src/main/res/src')
            }
        }

    }

有人可以帮助我，我无法理解我在这里做错了什么。任何帮助将不胜感激。提前致谢。

我使用这个类来使它工作：

object LocaleManager {

    val LANGUAGE_RUSSIAN = "ru"
    val LANGUAGE_UZBEK = "uz"
    val INITIALIZATED = "inited"
    private val LANGUAGE_KEY = "language_key"

    fun setLocale(c: Context): Context {
        return updateResources(c, getLanguage(c))
    }

    fun setNewLocale(c: Context, language: String): Context {
        initial(c)
        persistLanguage(c, language)
        return updateResources(c, language)
    }

    fun getLanguage(c: Context): String {
        val prefs = PreferenceManager.getDefaultSharedPreferences(c)
        return prefs.getString(LANGUAGE_KEY, LANGUAGE_RUSSIAN) ?: LANGUAGE_RUSSIAN
    }
    fun initial(c: Context){
        val prefs = PreferenceManager.getDefaultSharedPreferences(c)
        prefs.edit().putBoolean(INITIALIZATED,true).apply()
    }
    fun isInitialed(c: Context):Boolean{
        val prefs = PreferenceManager.getDefaultSharedPreferences(c)
        return prefs.getBoolean(INITIALIZATED,false)
    }
    fun restoreLang(c: Context){
        val prefs = PreferenceManager.getDefaultSharedPreferences(c)
        prefs.edit().putBoolean(INITIALIZATED,false).apply()
    }
    @SuppressLint("ApplySharedPref")
    private fun persistLanguage(c: Context, language: String) {
        val prefs = PreferenceManager.getDefaultSharedPreferences(c)
        prefs.edit().putString(LANGUAGE_KEY, language).commit()
    }

    private fun updateResources(context: Context, language: String): Context {
        var context = context
        val locale = Locale(language)
        Locale.setDefault(locale)

        val res = context.resources
        val config = Configuration(res.configuration)
        if (Build.VERSION.SDK_INT >= 17) {
            config.setLocale(locale)
            context = context.createConfigurationContext(config)
        } else {
            config.locale = locale
            res.updateConfiguration(config, res.displayMetrics)
        }
        return context
    }

    fun getLocale(res: Resources): Locale {
        val config = res.configuration
        return if (Build.VERSION.SDK_INT >= 24) config.locales.get(0) else config.locale
    }
}

然后在BaseActivity类中添加下一个方法：

override fun attachBaseContext(base: Context) {
    super.attachBaseContext(LocaleManager.setLocale(base))
}
