Why won't my nested ScrollView scroll till the end?

问题

My ListView does not scroll to the end of the screen.
It stops right at the top of the last item.

Below are the two codes I have been playing around with to get it to scroll to the end.
The tab layout is supposed to scroll too, to make space for the ListView to scroll till the end.
This feature works on all the other Fragments but won't work with the ScrollView.

<android.support.v4.widget.NestedScrollView 

xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:context="com.application.sweetiean.stlservicing.Serv_OverviewFragment">

<!-- TODO: Update blank fragment layout -->
<LinearLayout
    android:id="@+id/serv_OverviewTab"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="5dp"
    android:orientation="vertical">

    <ListView
        android:id="@+id/displayListView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

and

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
tools:context="com.application.sweetiean.stlservicing.Serv_OverviewFragment">

<!-- TODO: Update blank fragment layout -->


    <ListView
        android:id="@+id/displayListView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

I need some help.
