Inflate layout inside LinearLayout [android help]

Inflate layout inside LinearLayout

In the app that I'm developing, I have a Menu with icons that is on the right and left edges of the screen, and it mantains there in all the app's activities.

What I've done is first create the "MenuView" class activity where are defined all the menu's icons and their onClickListeners. Then the layout for this activity. In the layout I stablished 2 linearlayout's wich are each one on the border's of the screen (These refers to the menu) and a LinearLayout with the blank space inside the columns, where the other activities must go.

MenuViewActivity.java

public class MenuViewActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.menu_view);
    ...

    ((ImageView)this.findViewById(R.id.navButton)).setOnClickListener(launch_nav);

    final OnClickListener launch_nav = new OnClickListener() {
        @Override
        public void onClick(View v) {
            getBaseContext().startActivity(new Intent(getBaseContext(), Navigation.class));
        }
    };
    ...

menu_view.xml

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" 
tools:context="com.example.MenuViewActivity" >



    layout="@layout/custom_tittlebar" >



    
    android:id="@+id/lefthandmenu"
    android:layout_width="85dip"
    android:layout_height="match_parent"
    android:layout_below="@id/title"
    android:layout_alignParentLeft="true"
    android:orientation="vertical"       
    android:background="@drawable/border_cut" >

            ... />
    ...


    android:id="@+id/righthandmenu"
    android:layout_width="85dip"
    android:layout_height="match_parent"
    android:layout_below="@id/title"
    android:layout_alignParentRight="true"
    android:orientation="vertical"
    android:background="@drawable/border_cut" >

            ... />
    ...        



    android:id="@+id/activitycontent"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_toLeftOf="@id/righthandmenu"
    android:layout_toRightOf="@id/lefthandmenu"
    android:layout_below="@id/title"
    android:orientation="vertical" >    
   

So, what I must do now is to tell the program that other activities must go inside this last layout. For this, I do this in for example the Main class. I extend the activity to MenuViewActivity and the I inflate the layout.

MainClass.java

public class MainClass extends MenuViewActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    super.onCreate(savedInstanceState);


    LinearLayout inside_menu_view = (LinearLayout)findViewById(R.id.activitycontent);
    View this_layout = getLayoutInflater().inflate(R.layout.main, inside_menu_view);
    inside_menu_view.addView(this_layout);

But I'm getting an error on the logcat:
