title: Scrollview does not scroll when keyboard appears
body: <p>I have a few EditTexts in my RelativeLayout, and a button aligned at the bottom of it. When the keyboard pops up, I want my layout to resize (therefore, I'm using android:windowSoftInputMode="adjustResize") and also want it to be scrollable, because in smaller screens resizing it isn't enough.</p>
  
  <p>The problem is I can't get it to scroll at all!</p>
  
  <p>I do need the Button to stay at the bottom of the screen.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="#FFF"&gt;
  
      &lt;!-- some hidden RelativeLayouts, filling the whole screen --&gt;
  
  &lt;RelativeLayout
          android:id="@+id/form_layout"
          android:layout_width="match_parent"
          android:layout_height="match_parent"&gt;
  
      &lt;ScrollView
          android:layout_width="match_parent" android:layout_height="match_parent"
              android:fillViewport="true" android:layout_above="@+id/ok_btn"&gt;
  
          &lt;RelativeLayout
          android:layout_width="match_parent"
          android:layout_height="match_parent" android:background="#99000000" android:visibility="visible"&gt;
  
              &lt;View
              android:id="@+id/shade"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" android:layout_alignTop="@+id/logradouro1"
              android:background="#FFF" android:layout_marginTop="-30dp"/&gt;
  
              &lt;!-- some visible EditTexts and TextViews here --&gt;
  
          &lt;/RelativeLayout&gt;
  
      &lt;/ScrollView&gt;
  
      &lt;Button android:id="@+id/ok_btn"
              android:layout_width="match_parent"
              android:layout_height="50dp" android:background="@color/verdeBotao" android:text="Cadastrar"
              android:textColor="#FFF" android:layout_alignParentBottom="true"/&gt;
  
  &lt;/RelativeLayout&gt;
  
  
  &lt;/RelativeLayout&gt;

  <p>Below are 2 screenshots to illustrate what is happening. Please notice that I can't scroll when the keyboard is up.
  Thanks!</p>
