android - Height of a listview -

i have been trying make layout app, set android:layout_height="wrap_content".

this code ::

<scrollview xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:card_view="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context="com.example.hp.money.dashboard">      <linearlayout         android:layout_width="match_parent"         android:layout_height="match_parent"         android:orientation="vertical">          <android.support.v7.widget.cardview             android:id="@+id/cv_amount_display"             android:layout_width="match_parent"             android:layout_height="200dp">            .....         </android.support.v7.widget.cardview>          <android.support.v7.widget.cardview             android:layout_width="match_parent"             android:layout_height="wrap_content"             android:layout_gravity="center"             card_view:cardcornerradius="10dp">              <linearlayout                 android:layout_width="match_parent"                 android:layout_height="match_parent"                 android:orientation="vertical">                  <textview                     android:layout_width="match_parent"                     android:layout_height="wrap_content"                     android:text="@string/last_10_transaction" />                  <listview                     android:id="@+id/last_transactions_lv"                     android:layout_width="match_parent"                     android:layout_height="wrap_content"                     android:orientation="vertical" />             </linearlayout>         </android.support.v7.widget.cardview>     </linearlayout> </scrollview> 

i using listview inside scrollview, bad idea, know! leads scrolling issues, believe. have dynamically update data on screen during runtime, , think listview can handle it. if there's other view it, please suggest.

now, problem if data source of listview has 10 items, height of listview remains equal size of 1 listview element, height of listview set wrap_content, supposed resize accordingly. doesn't! how fix this?

this how looks, though listview has 10 items! listview 1 has heading last 10 transactions

why used scrollview??

i put scrollview, because, number of enteries in listview can many, want when user scrolls see entries not visible int listview, whole page gets scrolled, , not listview.

what mean " dynamically insert data listview during runtime". if modifying list data dynamically listview can handle internally. no need in case. can remove scrollview works fine.
