title: BottomNavigationView goes up when keyboard appears
body: <p><a href="https://i.stack.imgur.com/WAcle.png" rel="noreferrer">Image</a></p>
  
  <p>My BottomNavigationView works fine but it goes up when I press on the <code>EditText</code> to write on it. There is an image on the link above.</p>
  
  <p>This is my manifest in which I included <code>android:windowSoftInputMode="adjustPan"</code> but it doesn't work for me. Any other suggestions?
  </p>
  
  <pre><code>&lt;application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:supportsRtl="true"
      android:theme="@style/AppTheme"&gt;
      &lt;activity android:name=".MainActivity"
          android:windowSoftInputMode="adjustPan"&gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  &lt;/application&gt;
  </code></pre>
