/*Add these to MainActivity on create*/

final DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
final ListView drawerList = (ListView) drawerLayout.findViewById(R.id.list_drawer);
drawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, new String[]{"Rooms"}));
drawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) {
        
        /*you need to write this function, depends on what you want it to do when you click an item on the drawer*/
        changeFragment(......................);
        
        
        drawerList.setItemChecked(pos, true);
        drawerLayout.closeDrawer(drawerList);
    }
});

mDrawerToggle = new ActionBarDrawerToggle(
        this,
        drawerLayout,
        R.drawable.ic_drawer,
        R.string.abc_action_bar_up_description,
        R.string.abc_action_bar_up_description
);
drawerLayout.setDrawerListener(mDrawerToggle);

getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);


=====================================================================

Change the MainActivity layout to be

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context="comp4920.ping.MainActivity"
        tools:ignore="MergeRootFrame" />

    <ListView
        android:id="@+id/list_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:background="#fff"/>

</android.support.v4.widget.DrawerLayout>


====================================================================

Add the drawer_list_item.xml:

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textAppearance="@android:style/TextAppearance.Medium"
    android:minHeight="48dip"/>
