SettingsActivity에서 앱 내 로케일 (언어) 변경

Question

사용자가 앱 언어를 변경할 수 있기를 원합니다 (문자열은 strings-de/strings.xml 또는 strings-zh/strings.xml과 같은 폴더에 있음). 그것은 중국이나 뭐든 전화 설정을 변경하면 잘 작동하지만, 내가 뭘 하려는지 다음과 같습니다 : 나는 몇 조각으로 MainActivity가 있고 내 작업 표시 줄에 나는 사용자가 그것을 클릭하면 설정 아이콘이 있습니다 settingsActivity가 열리고 사용자가 선호하는 언어를 선택할 수있는 메뉴 항목이 있습니다. 사용자가 클릭하면 앱에서 선택한 언어의 문자열을 다시로드하고 사용해야합니다. 어떻게해야합니까? 코드가 어떤 활동에 속해 있습니까? 미리 감사드립니다. 여기

사용자가 언어를 선택할 수있는 XML의 일부 :

<ListPreference 
    android:defaultValue="en" 
    android:entries="@array/pref_language_select" 
    android:entryValues="@array/pref_language_values" 
    android:key="language_list" 
    android:negativeButtonText="@null" 
    android:positiveButtonText="@null" 
    android:title="@string/pref_title_language" /> 

여기에 언어 선택 목록에서 배열 :

<string-array name="pref_language_select"> 
    <item>Deutsch</item> 
    <item>English</item> 
    <item>中文</item> 
    <item>Espanol</item> 
    <item>Magyar</item> 
    <item>Srpski</item> 
    <item>Nederlands</item> 
</string-array> 
<string-array name="pref_language_values"> 
    <item>de</item> 
    <item>en</item> 
    <item>zh</item> 
    <item>es</item> 
    <item>mg</item> 
    <item>sr</item> 
    <item>nl</item>   
</string-array>

흥미로운 ..try이 :

Configuration config = getBaseContext().getResources().getConfiguration(); 

    String lang = "fr"//get your language here as you see fit 
    if (! config.locale.getLanguage().equals(lang)) 
    { 
     locale = new Locale(lang); 
     Locale.setDefault(locale); 
     config.locale = locale; 
     getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics()); 
    } 

이이 작업을 수행하는 경우 다음 변경 ONCONFIG 걱정 메신저에 대한

. 구성 변경 사항을 처리 할 때이 정확한 작업을 다시 수행해야합니다.
