Toolbar is hidden in nested PreferenceScreen
android,android-preferences,android-support-library,android-toolbar,preferencefragment
I found the solution on my own. I used a small work-around of all this nested PreferenceScreen's. I simply made a separation to different xml-preference files, created an additional Fragment which extends PreferenceFragment and there I show an appropriate nested preference screen. Maybe somebody would found this useful. Github sources...
Android OnPreferenceClickListener
java,android,preferencefragment,onpreferenceclicklistener
Edit: Make your SettingsFragment an inner class of PairActivity: public class PairActivity extends Activity { public class SettingsFragment extends PreferenceFragment { } } Then you can safely reference the activity with PairActivity.this. Edit: That's a nice answer you linked and it's indeed the proper way to use it like that....
Dialog Builder in PreferenceFragment
android,dialog,listpreference,preferencefragment
So I decided that I would just implement an extended ListPreference which deals with creating the confirmation dialog and voila, It now works perfectly. public class ThemeListPreference extends ListPreference { private int mClickedDialogEntryIndex; private Context mContext; public ThemeListPreference(Context ctxt) { this(ctxt, null); } public ThemeListPreference(Context ctxt, AttributeSet attrs) { super(ctxt,...

android,xml,checkboxpreference,preferencefragment
After a few trial and error I found out that I just overloaded the Preferences.

PreferenceFragment crashing, Null object Reference
android,preferenceactivity,preferencefragment
Credit should go to njzk2 for pointing out that it was a problem with a ListPreference finding a null value. It turns out that one of the Arrays was stored as an "integer-array" instead of a "string-array". Changing that fixed the problem.
Dynamically add EditTextPreference
I am using a helper class to build EditTextPreferences, using that I can do: Context context = getActivity(); PreferenceCategory statusCat = (PreferenceCategory) findPreference(context .getString(R.string.status_category)); EditTextPreference editTextPref = EditTextPrefBuilder.getBuilder(context) .setTitle("title") .setSummary("summary") .build(); statusCat.addPreference(editTextPref); You can of course also just create the EditTextPreference without this helper class, I just find the code...

Android PreferenceFragment : java.lang.RuntimeException
android,toolbar,android-actionbaractivity,preferencefragment
Move the following lines android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) getActivity().findViewById(R.id.toolbar); ((ActionBarActivity)getActivity()).setSupportActionBar(toolbar); To inside the callback Fragment#onActivityCreated(Bundle savedInstanceState). The reason is because when Fragment#onCreate(Bundle savedInstanceState) is called, the Activity wasn't instantiated yet. The method Fragment#getActivity() is probably returning null at this moment, and is guaranteed to return an Activity in...

How to bind PreferenceFragment to back end?

NullPointerException When Starting PreferenceActivity

In my arrays.xml file, the entry arrays were <string-array/> and the value arrays were <integer-array/>. My solution was to make the integer arrays string arrays. That seemed to fix the problem.
Preference has wrong value when rebuilding PreferenceFragment
java,android,oncreate,rebuild,preferencefragment
I figured it out: Like I assumed the problem was that the items always received the default values for their specific key. To overwrite this behaviour I had to call Apply() (commit would also work I guess) on the editor in the onCreate() method of my preference fragment like this:...

So by clicking on the PreferenceScreen, the latter was loaded with its preferences as if it was not hosted...
