Main Layout margin does not have any effect.

Created by: MoizAli

My view is as follows: <com.sothree.slidinguppanel.SlidingUpPanelLayout xmlns:sothree="http://schemas.android.com/apk/res-auto" android:id="@+id/sliding_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:gravity="bottom" sothree:umanoDragView="@+id/dragView" sothree:umanoOverlay="false" sothree:umanoPanelHeight="68dp" sothree:umanoParalaxOffset="100dp" sothree:umanoShadowHeight="4dp" >

    <ListView
        android:id="@+id/list_songs"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="@null"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"/>



    <FrameLayout
        android:id="@+id/dragView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center|top"></FrameLayout>

</com.sothree.slidinguppanel.SlidingUpPanelLayout>

As you can see I am providing my mainlayout (listview) with margin left and margin right. But I see that it has not effect when I run the app.
