<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="40dp" >

        <View
            android:id="@+id/seek_divider_1"
            android:layout_width="3dp"
            android:layout_height="fill_parent"
            android:layout_marginLeft="50dp"
            android:background="#FF0000" />

        <View
            android:id="@+id/seek_divider_2"
            android:layout_width="3dp"
            android:layout_height="fill_parent"
            android:layout_alignParentRight="true"
            android:layout_marginRight="30dp"
            android:background="#FF0000" />

        <SeekBar
            android:id="@+id/seekBar1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="false"
            android:layout_alignParentLeft="false"
            android:layout_centerHorizontal="true"
            android:layout_centerVertical="true"
            android:background="@null" />

    </RelativeLayout>

makes:

To change their position simply set their margin/-left or margin-right accordingly.

It's a 'hack' over anything else. but it should work?
