Question

I have some list preferences, but I don’t know how to save the individual values from the list. How do I do it? Here is what I have

http://i41.tinypic.com/dh4gvo.png

    Preference customPref = (Preference) findPreference("notificationPref");
    customPref.setOnPreferenceClickListener(new OnPreferenceClickListener() {

        public boolean onPreferenceClick(Preference preference) {

            SharedPreferences customSharedPreference = getSharedPreferences(
                    "notifications", Activity.MODE_PRIVATE);
            SharedPreferences.Editor editor = customSharedPreference
                    .edit();
            editor.putString("notification",
                    "The preference has been clicked");
            editor.commit();
            return true;
        }

    });

my list click listener is only for the main item in the list preferences page, but not the items in the popup itself. How do I save the choice selected in the popup itself?

This is usually automatic. In your preference screen XML, you should have something like this:

<ListPreference android:title="@string/Title" 
    android:summary="@string/Summary"
    android:key="PreferenceKey"
    android:defaultValue="VALUE_2"
    android:entries="@array/Entries"
    android:entryValues="@array/Values" />

And in your strings.xml:

<string name="Value1">Text for value 1</string>
<string name="Value2">Text for value 2</string>
<string name="Value3">Text for value 3</string>

<string-array name="Entries">
            <item>@string/Value1</item>
            <item>@string/Value2</item>
            <item>@string/Value2</item>
</string-array>
<string-array name="Values">
            <item>VALUE_1</item>
            <item>VALUE_2</item>
            <item>VALUE_3</item>
</string-array>

The “Values” array specify the (string) value saved in preferences, whereas the “Entries” array specify the text of the items displayed to the user. Each time the user select an item, its corresponding value in the “Values” array is saved to preferences under the specified key (“PreferenceKey” in this example).
