title: Android Constraint Layout doesn't stretch on full screen
body: <p>I have a problem with layout which won't stretch within high resolution like 1920x1080.
  As root layout I use Constraint Layout with following style:</p>
  
  <pre><code>&lt;android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
  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"
  android:focusable="true"
  android:focusableInTouchMode="true"
  tools:context="njc.nhutrinhgold.MainActivity"&gt;
  
  &lt;ImageView
      android:id="@+id/imgNen"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:adjustViewBounds="true"
      android:scaleType="fitXY"
      android:visibility="visible"
      app:layout_constraintDimensionRatio="16:9"
      app:srcCompat="@drawable/xxhdpibg"
      tools:layout_editor_absoluteX="0dp"
      tools:layout_editor_absoluteY="0dp"
      tools:layout_width="match_parent" /&gt;
  </code></pre>
  
  <p>and in Manifest.xml</p>
  
  <pre><code>&lt;supports-screens
      android:anyDensity="true"
      android:compatibleWidthLimitDp="960"
      android:largeScreens="true"
      android:largestWidthLimitDp="960"
      android:normalScreens="false"
      android:requiresSmallestWidthDp="960"
      android:resizeable="false"
      android:smallScreens="false"
      android:xlargeScreens="true" /&gt;
  </code></pre>
  
  <p>I want to stretch layout to any screen resolution but on emulator with high resolution it looks like this:</p>

  <p>Actually I didn't figured out what is the problem</p>
