android - Creating a Preference Screen with support (v21) Toolbar -

i having trouble using new material design toolbar in support library on preference screen.

i have settings.xml file below:

<preferencescreen xmlns:android="http://schemas.android.com/apk/res/android">     <preferencecategory         android:title="@string/addingitems"         android:key="pref_key_storage_settings">          <listpreference             android:key="pref_key_new_items"             android:title="@string/locationofnewitems"             android:summary="@string/locationofnewitemssummary"             android:entries="@array/new_items_entry"             android:entryvalues="@array/new_item_entry_value"             android:defaultvalue="1"/>      </preferencecategory> </preferencescreen> 

the strings defined elsewhere.

you can use preferencefragment, alternative preferenceactivity. so, here wrapping activity example:

public class mypreferenceactivity extends actionbaractivity {     @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.pref_with_actionbar);          android.support.v7.widget.toolbar toolbar = (android.support.v7.widget.toolbar) findviewbyid(uk.japplications.jcommon.r.id.toolbar);         setsupportactionbar(toolbar);          getfragmentmanager().begintransaction().replace(r.id.content_frame, new mypreferencefragment()).commit();     } } 

and here layout file (pref_with_actionbar):

<relativelayout     xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent">      <android.support.v7.widget.toolbar         android:id="@+id/toolbar"         android:layout_height="@dimen/action_bar_height"         android:layout_width="match_parent"         android:minheight="?attr/actionbarsize"         android:background="?attr/colorprimary"         app:theme="@style/toolbartheme.base"         app:popuptheme="@style/themeoverlay.appcompat.light"/>      <framelayout         android:id="@+id/content_frame"         android:layout_below="@+id/toolbar"         android:layout_width="match_parent"         android:layout_height="wrap_content" />  </relativelayout> 

and preferencefragment:

public static class mypreferencefragment extends preferencefragment{     @override     public void oncreate(final bundle savedinstancestate){         super.oncreate(savedinstancestate);         addpreferencesfromresource(r.xml.settings);     } } 

i hope helps someone.
