title: How to change the size of menu item icon in NavigationView?
body: <p>I have the following menu item:</p>
  
  <pre><code>&lt;item
     android:id="@+id/lock"
     android:checkable="true"
     android:title="@string/lock" &gt;
     &lt;menu&gt;
         &lt;item
            android:id="@+id/block_mess"
            android:checked="true"
            android:icon="@drawable/chantinnhan"
            android:title="@string/block_mess_string" /&gt;
          &lt;item
              android:id="@+id/block_call"
              android:checked="false"
              android:icon="@drawable/chancuocgoi"
              android:title="@string/block_call_string" /&gt;
          &lt;item
              android:id="@+id/lock_app"
              android:checked="false"
              android:icon="@drawable/khoaungdung"
              android:title="@string/lock_app_string" /&gt;
     &lt;/menu&gt;
  &lt;/item&gt;
  </code></pre>
  
  <p>...there's still more but it's really long</p>
  
  <p>but the icon is really small (even it has res 256x256). I'd like to make it bigger! Is this possible?</p>
  
  <p><strong>Here's the screenshot:</strong></p>

  <p>EDIT: OK, we both know that Google "lock" the icon size. But I want to know that can I "bypass" that lock and make something... customizable?</p>
