your linearlayout created outside horizontalscrollview, right layout this

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" android:background="@drawable/bg" > <imageview android:layout_width="fill_parent" android:layout_height="wrap_content" android:id="@+id/img_view" /> <horizontalscrollview android:id="@+id/horizontalscrollview1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginleft="5dip" android:layout_marginright="5dip" android:scrollbars="horizontal"> <linearlayout android:id="@+id/linearlayout1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" /> </horizontalscrollview> </linearlayout>
