        android:layout_width="match_parent"
        android:layout_height="match_parent" />

        <LinearLayout
            android:id="@+id/drawer_linear"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <!-- Toolbar -->
            <android.support.v7.widget.Toolbar
                xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:app="http://schemas.android.com/apk/res-auto"
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="#0000FF" />


            <!-- Listview to display slider menu -->
            <ListView
                android:id="@+id/list_slidermenu"
                android:layout_width="240dp"
                android:layout_height="match_parent"
                android:layout_gravity="start"
                android:choiceMode="singleChoice"
                android:divider="@color/list_divider"
                android:dividerHeight="1dp"       
                android:listSelector="@drawable/list_selector"
                android:background="@color/list_background"/>

        </LinearLayout>

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

Error : View android.widget.linearLayout app:id/drawer_linear is not a sliding drawer. What is wrong in this layout ?

Thanks for help,
