Can't get Action Bar in fragment class

Question

I have an activity with three fragment classes inside it. I get an error when trying to change the action bar title from inside of them. If I try to make the classes just public and not public static I get an error when I try to start that class. It should be pretty clear that the code is for preferences although that shouldn't change anything . Here's the code:

package com.simon.wikiics;  import android.preference.*; import android.os.*; import java.util.*;  public class MainSettingsActivity extends PreferenceActivity {      @Override     protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);  }  @Override public void onBuildHeaders(List<Header> target) {     loadHeadersFromResource(R.xml.headers, target); }  //If I don't make the classes static my app force closes when I try to start them public static class NavigationSettingsActivity extends PreferenceFragment {      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         addPreferencesFromResource(R.xml.navigation);         //The getActionBar() is what is giving me the error         getActionBar().setTitle("Navigation");      } }  public static class InterfaceSettingsActivity extends PreferenceFragment {      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         addPreferencesFromResource(R.xml.interf);         //The getActionBar() is what is giving me the error         getActionBar().setTitle("Interface");     }  }  public static class OtherSettingsActivity extends PreferenceFragment {      @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         addPreferencesFromResource(R.xml.other);         //The getActionBar() is what is giving me the error         getActionBar().setTitle("Other");     } } }

@Robert Estivil If you are using AppCompatActivity then use this:

actionBar = ((AppCompatActivity)getActivity()).getSupportActionBar();
