title: Relative Layout inside a ScrollView - Not scrolling
body: <p>I have a relative layout as child of Scrollview. I already tried a bunch of answers in here but the scroll isn't working.</p>
  
  <p>That's my xml file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;ScrollView 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:scrollbars="none"
      android:fillViewport="true"
      android:background="@drawable/home_bg_branco" &gt;
  
      &lt;RelativeLayout
          android:id="@+id/relative_categoria"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="vertical" &gt;
  
          &lt;ImageView
              android:id="@+id/categoria_placeholder_slider_listview"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_marginTop="-3dp"
              android:contentDescription="@string/home_placeholder_slider"
              android:src="@drawable/home_placeholder_slider"
              android:visibility="visible" /&gt;
  
          &lt;ImageSwitcher
              android:id="@+id/home_imageswitcher_slider_listview"
              android:layout_width="fill_parent"
              android:layout_height="0dp"
              android:layout_alignBottom="@id/categoria_placeholder_slider_listview"
              android:layout_alignLeft="@id/categoria_placeholder_slider_listview"
              android:layout_alignRight="@id/categoria_placeholder_slider_listview"
              android:layout_alignTop="@id/categoria_placeholder_slider_listview"
              android:scaleType="fitXY" /&gt;
  
          &lt;ListView
              android:id="@+id/listViewCategoria"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:layout_below="@id/home_imageswitcher_slider_listview"
              tools:ignore="NestedScrolling" &gt;
          &lt;/ListView&gt;
  
          &lt;ImageView
              android:id="@+id/categoria_cores_listview"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_alignBottom="@+id/categoria_placeholder_slider_listview"
              android:layout_alignParentEnd="true"
              android:layout_alignParentLeft="true"
              android:contentDescription="@string/img_cores"
              android:src="@drawable/img_cores" /&gt;
  
          &lt;ImageView
              android:id="@+id/categoria_destaque_listview"
              android:layout_width="fill_parent"
              android:layout_height="wrap_content"
              android:layout_alignStart="@id/categoria_placeholder_slider_listview"
              android:contentDescription="@string/img_destaques"
              android:src="@drawable/img_destaques" /&gt;
      &lt;/RelativeLayout&gt;
  
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>Another thing: i disabled the listview scroll to avoid conflicts. </p>
  
  <p>Thanks in advance!</p>
