지금 제가 하려는게 뷰페이저에서 각화면에 필요한 액션바 버튼을 넣을려고하는데

위의 코드에서 빨간글씨로된부분을 입력해실행하면 액션바버튼이뜨는데

밑의코드에서는 똑같이해도 아무것도 안나오네요

왜그런지알려주실분있ㄴ요 ㅠㅠㅠ

package com.example.allshare;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import android.widget.LinearLayout;

public class ListActivity extends Fragment {
	EditText edt1;
	Context mContext;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
	}

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		LinearLayout layout = (LinearLayout) inflater.inflate(
				R.layout.activity_list, container, false);

		edt1 = (EditText) layout.findViewById(R.id.edt1);
		edt1.setInputType(0);
		edt1.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				edt1.setInputType(1);
				InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
				mgr.showSoftInput(edt1, InputMethodManager.SHOW_IMPLICIT);
			}

			private InputMethodManager getSystemService(
					String inputMethodService) {
				return null;
			}
		});
		return layout;
	}

	public boolean onCreateOptionsMenu(Menu menu) {
	    getActivity().getMenuInflater().inflate(R.menu.activity_actions, menu);
	    return true;
	}
	
	public boolean onOptionsItemSelected(android.view.MenuItem item, Menu menu) {
		switch (item.getItemId()) {
		case R.id.action_search:
			return true;
		case R.id.action_settings:
			return true;
		default:
			return super.onOptionsItemSelected(item);
		}
	}
}

<?xml version="1.0" encoding="UTF-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_search"
        android:showAsAction="always"
        android:title="@string/search"/>
    <item
        android:id="@+id/action_settings"
        android:showAsAction="never"
        android:title="@string/action_settings"/>

</menu>

첫번째 소스에는

ActionBar bar = getActionBar();
        bar.setDisplayOptions(ActionBar.DISPLAY_HOME_AS_UP
                | ActionBar.DISPLAY_SHOW_HOME | ActionBar.DISPLAY_USE_LOGO
                | ActionBar.DISPLAY_SHOW_TITLE);

이런식으로 actionbar 설정하는 소스가 있지만 두번째 소스에는 저부분이 없죠...
