fit seekBar inside a drawer

how i can fit a seekBar to stay inside a drawer boundary?

this is my drawerLayout

<!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout xmlns:android="http://ift.tt/nIICcg"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />

    <LinearLayout
        android:id="@+id/right_drawer_ll"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="end"
        android:orientation="vertical"
        android:visibility="visible" >

        <SeekBar
            android:id="@+id/seekBar1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <ListView
            android:id="@+id/right_drawer"
            android:layout_width="240dp"
            android:layout_height="match_parent"
            android:layout_gravity="right"
            android:background="#123456"
            android:choiceMode="singleChoice"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp" />
    </LinearLayout>

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

with this code, the seekBar is shown inside the drawerLayout, not inside the rightDrawer boundary.

UPDATE

is it possible to achieve this?

thanks in advance.
