title: Layout in Emulator is not matching that from Android Studio
body: <p>So I'm completely new to Android Development and I'm working through a book on Android Game Development. First game we build is called Tappy Defender. </p>
  
  <p>Anyway, they provide me with background image and told me to put a button and a TextView. I put the background in the drawable folder and assigned it to the background for the Activity, I also aligned both the TextView and the button.</p>
  
  <p>However, when I build and run the program in the emulator, both the button and the TextView are located in the top left corner (in landscape) and are overlapping each other. The background also doesn't show at all.</p>
  
  <p>I'm so confused as to what it is that I'm doing wrong as I followed the steps correctly and have gone over it several times.</p>
  
  <p>Any help appreciated.</p>
  
  <p>I've included the .xml file too:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

      &lt;TextView
          android:id="@+id/textHighScore"

          tools:layout_editor_absoluteY="258dp"
          tools:text="High Score: 99999" /&gt;
  
  &lt;/android.support.constraint.ConstraintLayout&gt;
