Answer 1

I got the desirable result by using the transparent background for TabHost and use the shaded background as first layer:

  <?xml version="1.0" encoding="utf-8"?>

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="@drawable/bac_tab"
android:id="@+id/mymain_layout" android:weightSum="1">

*<!---by adding this in the background----->

    <RelativeLayout android:gravity="bottom"
            android:layout_width="fill_parent" android:layout_height="51dp"
            android:layout_alignParentTop="true" android:layout_alignParentLeft="true"
            android:background="@drawable/newbac"></RelativeLayout>

        android:id="@android:id/tabhost" android:layout_width="fill_parent"
