Your problem is with referring to the ListView in the DrawerLayout incorrectly in the MrsClubb activity. Here is an example of how you should be using and referring to the ListView.

<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
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>
    <ListView
        android:id="@+id/drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>

Now you can refer to the ListView in the DrawerLayout as:

ListViewlv= (ListView) findViewByid(R.id.drawer);

Using Android provided IDs can sometimes get tricky and I believe this is where you have gone wrong.

Solution 2:

Here is your problem:

 java.lang.NullPointerException: Attempt to invoke virtual method 'void
android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference

Looks like your listView is null, check to make sure you are declaring and finding it correctly in your activity.
