Reading shared preferences

i'm using shared preferences for the settings menu of my android app. it's working very well but i didn't know how to use these settings on my code:

For example how to use the selected language and use it in another activity: 

    <PreferenceCategory 
    android:title="General Settings"
    android:key="general_settings"

    >
    <ListPreference 
        android:key="language"
        android:title="Language"
        android:summary="Define the default language"
        android:defaultValue="Spanish" 
        android:entries="@array/Languages"
        android:entryValues="@array/LanguagesValues"

    />

On code behind;

SharedPreferences prefs = this.getSharedPreferences("general_settings", Context.MODE_PRIVATE);
String lanSettings = prefs.getString("language", null);

you have to set and read shared pref settings. For example:

Set:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = settings.edit(); 
                        editor.putString("language", language);
                        editor.commit();

Read:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
String language = settings.getString("language", "");

You could use a RadioGroup, set the Sharedpref and work with it.

Hope this help!
