body: <p>I'm adding a <code>BottomNavigationView</code> to My <code>MainActivity</code>
  at first show nothing wrong but after click on other items, <code>BottomNavigationView</code> strangely moving up and down. In other projects, I had never this problem and I don't know why I am getting this:</p>
  
  <p>p.s: In default fragment (which is first at right in screenshot) I have a content but in other fragments, I have no content.</p>
  
  <p>Here is my <code>MainActivity</code> layout:</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

      tools:context="com.activity.MainActivity"&gt;
  
      &lt;FrameLayout
          android:id="@+id/MainActivity_FrameLayout"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_above="@+id/MainActivity_BottomView" /&gt;

  &lt;/RelativeLayout&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>and here is the screenshot of how does shown</p>
  
  <p><a href="https://i.stack.imgur.com/ttwLb.png" rel="nofollow noreferrer">after clicking on another item</a></p>
  
  <p><a href="https://i.stack.imgur.com/bHzaZ.png" rel="nofollow noreferrer">and when select default item again</a></p>
  
  <p>--- EDIT ---</p>
  
  <p>I realized it's happen when use <code>CoordinatorLayout</code> , <code>AppBarLayout</code> and <code>CollapsingToolbarLayout</code> in fragment . After remove that lines app work without any problem .</p>
  
  <p>Here is my fragment Layout :</p>
