title: Can't move any elements in Android Studio for RelativeLayout
body: <p>I'm trying to add some buttons/textviews or any other components to my relativelayout. I can't place them anywhere but top left. However, if I edit XML code it works fine. </p>

  <p>I already changed my layout to relativeLayout but still no luck. (Android Studio 3.3)</p>
  
  <p>My layout xml is:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout
      android:id="@+id/activity_main"
      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:paddingLeft="16dp"
      android:paddingRight="16dp"
      android:paddingTop="16dp"
      android:paddingBottom="16dp"
      tools:context=".MainActivity"&gt;
  
      &lt;Button
          android:id="@+id/button"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="Button" /&gt;
  
      &lt;TextView
          android:id="@+id/textView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="TextView" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>I would expect to move these buttons/textviews relative to each other but they just stuck at top left.</p>
