Answer 2

You can use DrawerLayout and inside it use AnimatedExpandableListView here

Example:

<FrameLayout
    android:id="@+id/content_frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent"></FrameLayout>

<AnimatedExpandableListView
    android:id="@+id/left_drawer_user_courses"
    android:layout_width="match_parent"

    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="@color/side_menu_color"
    android:choiceMode="singleChoice"
    android:divider="@drawable/line_bettwen_courses"
    android:groupIndicator="@drawable/expandable_list_indicator" />

<LinearLayout
    android:id="@+id/right_drawer_user_info"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:layout_gravity="end"
    android:background="@color/side_menu_color"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:orientation="vertical">

    <include layout="@layout/userinfo_side_menu"></include>
</LinearLayout>
