I create simple project using actionbar ,i've one class and one fragment class, i define custome actionbar in class, and my problem, how to call method actionbar in fragment class from class, this code like below :
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_holder);
fragmentArray = new ConferenceFragment[8];
// Load main fragment
fragment = new HomeFragment();
fragmentArray[0] = fragment;
currentFragmentIndex = 0;
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.replace(R.id.holder, fragment).commit();
// initMenuBar();
}
public void initMenuBar(){
ActionBar actionBar = getActionBar();
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
actionBar.setCustomView(R.layout.menu_bar);
ImageButton buttonSideMenu = (ImageButton) findViewById(R.id.bt_menu);
buttonSideMenu.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
toggle();
// Toast.makeText(getApplicationContext(), "Clicked!",Toast.LENGTH_LONG).show();
}
});
actionBar.show();
}
// fragment class
public class HomeFragment extends Fragment{
View v;
MainActivity mainactivity;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
mainActivity.initMenuBar(); // ERROR IN THIS LINE
super.onCreateView(inflater, container, savedInstanceState);
v = inflater.inflate(R.layout.home_fragment, container, false);
return v;
}
}

You need to get your MainActivity's context reference in your fragment to access activity's method.
Try this.
public class HomeFragment extends Fragment{
View v;
Context mContext;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreateView(inflater, container, savedInstanceState);
v = inflater.inflate(R.layout.home_fragment, container, false);
mContext = getActivity();
((MainActivity) mContext).initMenuBar();
return v;
}
}

ActionBar is traditionally the part of Activity and is available to activity only. You can get Activity instance by calling getActivity() from fragment and cast it to your activity then call public method to do whatever you want.
But the better option is to use ToolBar explained here support library v7
