I have a very simple setup following your demo project

<preference-headers xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:unified="http://schemas.android.com/apk/res/bostone.android.jobrio" >
    <header
        unified:fragment="bostone.android.jobrio.JobrioPreferenceActivity$AccountsFragment"
        unified:title="@string/pref_header_general"
        unified:preferenceRes="@xml/pref_general" />
</preference-headers>

pref_general.xml

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
    <CheckBoxPreference
        android:defaultValue="false"
        android:key="linkedin_login"
        android:summary="@string/pref_description_linkedin_account"
        android:title="@string/pref_title_linkedin_account" />
</PreferenceScreen>

And the java code

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        setHeaderRes(R.xml.pref_headers);
        setSharedPreferencesName(getApplicationContext().getPackageName());
        setSharedPreferencesMode(Context.MODE_PRIVATE);
        super.onCreate(savedInstanceState);
        final ActionBar ab = getSupportActionBar();
        ab.setDisplayHomeAsUpEnabled(true);
    }

    public static class AccountsFragment extends UnifiedPreferenceFragment {

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
        }

        @Override
        public void onAttach(Activity activity) {
            super.onAttach(activity);
        }

    }

Preferences screen comes up just fine and checkbox property acts appropriately. What puzzle me is that unified:fragment="bostone.android.jobrio.JobrioPreferenceActivity$AccountsFragment" is seemingly ignored and in fact I can put any gibberish as fragment value and it will not generate any errors. As far as AccountsFragment goes - its onCreate and onAttach methods are never called.

I must be doing something wrong here?

Thanks,

Hi today I tried to integrate your lib. It supposed to be easy but it is not. Here is the problem.

My pref_headers.xml

<header
    unified:fragment="com.tasomaniac.hdfilmizle.preference.GeneralPreferenceFragment"
    unified:title="@string/settings"
    unified:preferenceRes="@xml/pref_general" />
<header
    unified:fragment="com.tasomaniac.hdfilmizle.preference.OnbellekPreferenceFragment"
    unified:title="Önbellek Ayarları"
    unified:preferenceRes="@xml/pref_onbellek" />

pref_onbellek.xml is here:

    <CheckBoxPreference
        android:summary="@string/pref_summary_cache"
        android:title="@string/pref_title_cache_flag"
        android:key="@string/pref_key_flag_cache"
        android:defaultValue="true" />
     <Preference
        android:title="@string/pref_title_erasecache_flag"
        android:key="erasecache_flag" />

Here I have item. In OnbellekPreferenceFragment.java I am calling it like below

@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

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

            public boolean onPreferenceClick(Preference preference) {
                Toast.makeText(getActivity().getApplicationContext(),"Önbellek Silindi!",Toast.LENGTH_LONG).show();


                    new Thread(new Runnable() {
                        public void run() {
                            new ImageLoader(getActivity().getApplicationContext()).clearCache();
                        }
                    }).start();
                    return true;

            }
        });
    }

The problem is that it is not working. Actually I had a break point before super.onCreate() function. The breakpoint was not called at all. What can be a problem? When I supply an intent it is working.

Hey, I'm using the unified preference and it works perfectly fine in two of my devices (smasung galaxy s2 and nexus 4) but when i try it on my galaxy tab it has an exception in the line: super.onCreate(savedInstanceState);

I get this error, if I try to compile the library:

Adding to the project library created a folder xml for a file called hml. In the activity of adding the file and get an error

every attr has to have a format field in preferenceheader in values files..

otherwise you get aapt erros..its hanging on title and icon..so i am putting string format for title and integer format for icon.

Hi,

Can't see the actionbar (and thus a menu option) on honeycomb. My app project has a library set to unifiedpreference which in turn has a library set to ActionBarSherlock. Works fine in Jelly Bean and Gingerbread but unfortunately not on Honeycomb (3.2) Any clues??

Hi,

I have tried to compile your example project. I added all the dependency needed (comp + sherlock).

The issue is relative to UnifiedPreference / library / res / values / atrs.xml Intellij has an issue with PreferenceHeader

<declare-styleable name="PreferenceHeader">

Intellij doesn't find PreferenceHeader class

In my project I have created a view with some custom XML properties and I use atrs.xml for that purpose. The point is that in atrs.xml, I point the custom view class to make it work. After in the XML layout I point the class path too.

I noticed that there is no PreferenceHeader class in the project. And I don't know what to do!

Can you help me ?

Regards
