body: <p>I have a vertical big image, I want to make it scrollable.
  I've made it like this,</p>
  
  <pre><code>&lt;ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:layout_below="@+id/logoimage"
              android:scrollbarAlwaysDrawVerticalTrack="true" &gt;
  
          &lt;ImageView
              android:contentDescription="Specs"
              android:adjustViewBounds="true"
              android:id="@+id/imageScroll"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:scrollbars="vertical"
              android:src="@drawable/rules" &gt;
