Evaluate PreferenceFragment Support about actionbarsherlock HOT 21 CLOSED

Can't be done because of method visibility on PreferenceManager and PreferenceScreen.

This may be possible with a bit of work on second thought...

I have a some idea of this.

PreferenceFragment is just abstract class that extends Fragment that depend on PreferenceActivity.

from actionbarsherlock.

I have the beginnings of the class here: https://gist.github.com/1108374

It is based on the decompiled source of Android 3.1. It doesn't compile at present but it's a start. There are a lot of internal APIs in use on the official version of the class. We can't depend on PreferenceActivity so some of these methods will have to have their implementations duplicated. I don't have the time to look at it just yet.

This is being worked on in a private repo for now. Once it is compiling I'll make it public. It will be at https://github.com/JakeWharton/Android-PreferenceFragment.

Have you made any progress since Augustus 2010? I would like to set my preference in a ViewPager but that gives me serious headache!

from actionbarsherlock.

Haven't touched it since. Working on ABS v4 now. I might try it once that is completed.

@ChristopheVersieux it shouldn't be too difficult to do it yourself, here's the ICS source for PreferenceFragment

from actionbarsherlock.

I believe it uses internal PreferenceManager and PreferenceScreen APIs which is why I gave up on it initially until the sources were available. The tricky part will be ensuring it can still work with things that extend android.preference.Preference. It's not a requirement, but would be great for a proper solution.

Thank a lot for your help, I found this one in the meanwhile: http://forum.xda-developers.com/showpost.php?p=19719977&postcount=1
With a perfectly working example.

Great job everybody and thank for your quick help.

from actionbarsherlock.

Cool. Thanks for the link. That method uses reflection to access the internal APIs so I'll still probably have a go at creating a proper implementation eventually. Glad that works for you for now though.

Hi Jake, do you plan to work on it? It s not the most useful class in the world, but it would help to have it :)

from actionbarsherlock.

Please continue development on this, I beg you.

from actionbarsherlock.

Yes - I need to use loaders and fragments in preference activity when some items are clicked and cannot!

Here seems to be an impressive Unified solution:

@paulpv did you manage to use UnifiedPreference as a SherlockFragment? I am experienceing the following issue:

04-18 03:59:26.000: E/AndroidRuntime(8437): FATAL EXCEPTION: main

NetSettingsPrefsFragment extends UnifiedPreferenceFragment

Hello, I have this code, and when trying to adapt it for use actionbarsherlock I can not use the getFragmentManager, that I can do?

Change to SherlockPreferenceActivity and actionbar by getSupportActionBar, but getFragmentManager fails me ... Why?

public class Settings extends PreferenceActivity{

@OverRide
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

ActionBar actionBar = getActionBar();
actionBar.setTitle(R.string.preferencias);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setHomeButtonEnabled(true);
actionBar.setIcon(R.drawable.actionbar_cerrar);

getFragmentManager().beginTransaction().replace(android.R.id.content,
new SettingsFragment()).commit();
}

Hi Jake,

are you still working on this or do you plan to?

from actionbarsherlock.

I wrote a compatibility layer for PreferenceFragment. Java reflection is used extensively to access private/hidden methods and fields. It's available here:

https://github.com/kolavar/android-support-v4-preferencefragment

from actionbarsherlock.

@kolavar, your compatibility layer is brilliant, and working perfectly in my app. Thank you so much for the contribution. I have mostly had success using it in combination with ABS by having your PreferenceFragment class extend from SherlockFragment instead of the Fragment class in the support library.

from actionbarsherlock.

@kolavar , yep, compatibility is great! Thank you very much!
