Get rid of extra padding above in PreferenceFragment
You are trying to add a PreferenceCategory with no title, which is causing the empty space. The following line is the problem: PreferenceCategory cat1 = new PreferenceCategory(root.getContext()); root.addPreference(cat1); So you can add title to your preference category like this : PreferenceCategory cat1 = new PreferenceCategory(root.getContext()); cat1.setTitle("Category"); root.addPreference(cat1); If you don't...
How to bind PreferenceFragment to back end?
android,android-preferences,preferencefragment
Since it has method for registering listener: registerOnSharedPreferenceChangeListener(), you can do it via implementing SharedPreferences.OnSharedPreferenceChangeListener interface and registering prefs for changes listening, something like: @Override public void onResume() { super.onResume(); getPreferenceManager().getSharedPreferences().registerOnSharedPreferenceChangeListener(this); } @Override public void onPause() { getPreferenceManager().getSharedPreferences().unregisterOnSharedPreferenceChangeListener(this); super.onPause();...
Display settings using “Settings” in triple-dot menu
Settings in Overflow Menu In order to use the Settings in the overflow menu, you need to override the onOptionsItemSelected method, if not already and handle the correct id. @Override public boolean onOptionsItemSelected(MenuItem item) { int id = item.getItemId(); if (id == R.id.action_settings) { // Code to show settings. return...
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:...
Can't switch PreferenceFragment from ActionBarActivity
android,android-viewpager,appcompat,preferencefragment
You can use PreferenceFragment with getFragmentManager even if you're using ActionBarActivity (on APIs above 11 of course). But i get errors like: Type mismatch: cannot convert from AppearencePrefFragment to Fragment ... The problem is the FragmentPagerAdapter only takes either support or native implementation of fragment manager. This means you can't...
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.
PreferenceFragment overlaps the Main Activity's Layout?

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...
Clicking on preference screen does not attach preference fragment
Well the problem was that in the preference.xml file the PreferenceScreen tag was fully deployed with other preferences, the ones that were supposed to be loaded with the second preference fragment. So by clicking on the PreferenceScreen, the latter was loaded with its preferences as if it was not hosted...

EditTextPreference crashes on OK press
android,android-preferences,spannablestring,edittextpreference,preferencefragment
Because it didn't appear to have anything to do with the updateAll() method, I decided to catch the IndexOutOfBounds exception, which solved the problem. @Override public void onSharedPreferenceChanged(SharedPreferences prefs, String key) { try { // updating and stuff } catch (IndexOutOfBoundsException e) { e.printStackTrace(); } } ...
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 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...

Android checkboxpreference disabled even though it's enabled in XML
android,xml,checkboxpreference,preferencefragment
After a few trial and error I found out that I just overloaded the Preferences. The slimmer and much cleaner version that works looks like this: <PreferenceCategory android:title="Network Service" > <CheckBoxPreference android:key="@string/communication_option" android:defaultValue="true" android:summary="Allows down- and upload." android:title="Enable server communication" /> <CheckBoxPreference android:dependency="communication_option" android:key="@string/wifi_sync_option" android:defaultValue="true" android:summary="Do...

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 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....
