title: Kotlin synthetic extension and several include same layout
body: <p>How to access to view using kotlin synthetic extension if I have a layout like below:</p>
  
  <p>file:two_days_view.xml</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical"&gt;
  
      &lt;include
          android:id="@+id/day1"
          layout="@layout/day_row"
          android:layout_width="match_parent"
          android:layout_height="wrap_content" /&gt;
  
      &lt;include
          android:id="@+id/day2"
          layout="@layout/day_row"
          android:layout_width="match_parent"
          android:layout_height="wrap_content" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>file: day_row.xml</p>
  
  <pre><code>   &lt;LinearLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="vertical"       &gt;
  
          &lt;TextView
              android:id="@+id/dayName"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content" /&gt;
  
      &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>How to access to dayName? I looked for some like this:</p>
  
  <pre><code>day1.dayName.text = "xxx"
  day2.dayName.text = "sss"
  </code></pre>
  
  <p>I see in Studio that I have access to <code>dayName</code> but to which one of dayName TextView is reference to?</p>
  
  <p>Normal if I have only one included layout it works fine. But now I have multiple times included same layout.</p>
  
  <p>of course I can always do:</p>
  
  <pre><code>day1.findViewById(R.id.dayName).text = "xxx"
  </code></pre>
  
  <p>but I'm looking for nice solution. :)</p>
