Android layout title bar is not visible

Question

I have created xml layout file. And when I give it as content to my Activity the TITLE BAR IS NOT VISIBLE. How can I make it visible. I tried to use setTitle("Title");

protected void onCreate(Bundle savedInstanceState) { 
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); 
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
super.onCreate(savedInstanceState); 
Bundle b = getIntent().getExtras(); 
int layoutId = b.getInt("layout");
Log.d("====>>>", " " + layoutId);
setContentView(layoutId); 
setTitle("Title"); 
}

function in onCreate() method. I is not work. This is my xml file.

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ScrollView01"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context="com.universityapp.enrollee.FacultyInformationActivity"
    android:scrollbars="vertical"
    >

     <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="@string/text_faculty_information_agro"
        android:textSize="15dp"
        android:textAlignment="center"
    />
</RelativeLayout>
</ScrollView>

I start activity via ListView:

 profListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

            switch (position){
                case 0:
                    facultyInfoIntent = new Intent(getBaseContext(), FacultyInformationActivity.class);
                    Bundle b = new Bundle();
                    b.putInt("layout", facultyLayoutNames[position]);
                    facultyInfoIntent.putExtras(b);
                    startActivity(facultyInfoIntent);
            }

            Log.d("Selected faculty", facultiNames[position]);
        }
    });

This is my Manifest:
