Why my Android Listview is not scrolling?

[mandajacobs3242]

I have made a xml display with some items . But my listView of that xml is not scrolling. I have made a scrollView and the listView is inside the scrollView , is it a problem ? If I design display with keeping the listView out side the scrollView, then the lisViw is not showing on my android device display. I need such a display where need a scrollView and scrolling listview. My code is given below.\[code\]<?xml version="1.0" encoding="utf-8"?><merge xmlns:android="http://schemas.android.com/apk/res/android" ><LinearLayout android:layout_width="fill_parent"android:layout_height="fill_parent"android:background="#FFFFFF"androidrientation="vertical" ><LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/head_logo" ></LinearLayout><LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" androidrientation="horizontal" > <Button android:id="@+id/cardlistButton" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:background="@drawable/head_menu04" /> <View android:layout_width="1dip" android:layout_height="fill_parent" android:background="#ffffff" /> <Button android:id="@+id/cameraButton" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:background="@drawable/head_menu02" /> <View android:layout_width="1dip" android:layout_height="fill_parent" android:background="#ffffff" /> <Button android:id="@+id/homeButton" android:layout_width="0dip" android:layout_height="wrap_content" android:layout_weight="1" android:background="@drawable/head_menu03" /></LinearLayout><LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/title_detail" android:gravity="right|center_vertical" ></LinearLayout><ScrollView android:layout_width="fill_parent" android:layout_height="wrap_content" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="#FFFFFF" android:gravity="center" androidrientation="vertical" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginLeft="15dip" android:layout_marginRight="15dip" androidrientation="vertical" androidaddingBottom="10dip" androidaddingTop="15dip" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="7dip" androidrientation="horizontal" > <TextView android:layout_width="80dip" android:layout_height="wrap_content" android:gravity="left" android:text="STATUS :" android:textColor="#666666" android:textStyle="bold" /> <TextView android:id="@+id/pdtvText1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="5dip" android:text="" android:textColor="#666666" android:textStyle="bold" /> </LinearLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="7dip" androidrientation="horizontal" > <TextView android:layout_width="80dip" android:layout_height="wrap_content" android:gravity="left" android:text="ע
