У меня есть еще 5 cardviews внутри моей LinearLayout, но я только что вставили 1. Я не знаю, что вызывает проблемы с Scrollview. Я уже пробовал удалить первый linearlayout, но не работал.

вид прокрутки не прокручивать до его содержание достигает своего родителя размер

, чтобы понять, что взглянуть на этот пример

<?xml version="1.0" encoding="utf-8"?> 
    <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/frame" 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     xmlns:tools="http://schemas.android.com/tools" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" 
     tools:context=".MainActivity" 
     tools:showIn="@layout/app_bar_main"> 
     <LinearLayout 
      android:layout_width="match_parent" 
      android:orientation="vertical" 
      android:layout_marginTop="30dp" 
      android:layout_height="wrap_content"> 

// now scroll is 200dp in height 
      <ScrollView 
       android:layout_width="match_parent" 
       android:layout_height="200dp"> 
// child of scroll 
       <LinearLayout 
        android:layout_width="match_parent" 
        android:orientation="vertical" 
        android:layout_height="200dp"> 

//inner children have more height than scroll view height (total 600dp) which made scroll view to scroll 
       <LinearLayout 
        android:background="#000" 
        android:layout_width="match_parent" 
        android:layout_height="300dp"></LinearLayout> 

        <LinearLayout 
          android:background="#0F0" 
         android:layout_width="match_parent" 
         android:layout_height="300dp"></LinearLayout> 

       </LinearLayout> 
      </ScrollView> 
     </LinearLayout> 

    </FrameLayout>
