I have written a code for Menus's in Android but it is now showing up in my activity, here is my code
I am only displaying my relevant code here,
Manifest.xml 
<uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="21" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppBaseTheme" >
MainActivity.Java
public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        super.onCreateOptionsMenu(menu);
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        switch (item.getItemId()) {
        // Some action here
        }
    }
}
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.androidex1.MainActivity" >
   <item android:id="@+id/item1"
       android:title="one" />
    <item android:id="@+id/item2"
        android:title="two" />
    <item android:id="@+id/item3"
        android:title="three" />
    <item android:id="@+id/item4"
        android:title="four" />
</menu>
Steps tried before
Menu Items are not showing on Action Bar
Result:
Tried but still menu's are not appearing
Android options menu not displaying
Result:
Menu's still don't appear.
Result:
Never added that attribute.
Option Menu does not appear in Android
Result:
super.onCreateOptionsMenu(menu); is also added in the code but still the menu's don't appear.
My problem I would like to see only the menu not the actionbar, what could be the problem ? I am not getting any errors and the main problem is that I am not able to see the menu itself.
