title: android:layout_width="0dp" does not work for ScrollView in a fragment
body: <p>The ScrollView in the following layout does not show at all:</p>
  <pre><code>    &lt;FrameLayout
          android:layout_width=&quot;match_parent&quot;
          android:layout_height=&quot;match_parent&quot;&gt;
  
          &lt;LinearLayout
              style=&quot;@style/FragmentLayout&quot;
              android:padding=&quot;5dp&quot;&gt;
  
              &lt;LinearLayout
                  android:layout_width=&quot;match_parent&quot;
                  android:layout_height=&quot;wrap_content&quot;
                  android:layout_marginTop=&quot;20dip&quot;
                  android:orientation=&quot;vertical&quot;&gt;
  ...
              &lt;/LinearLayout&gt;
  
              &lt;View
                  android:layout_width=&quot;match_parent&quot;
                  android:layout_height=&quot;2dp&quot;
                  android:background=&quot;@color/DodgerBlue&quot; /&gt;
  
              &lt;TableLayout style=&quot;@style/TableLayoutFieldGroup&quot;&gt;
  
   ...
              &lt;/TableLayout&gt;
  
              &lt;ScrollView
                  android:id=&quot;@+id/scrollView&quot;
                  android:layout_width=&quot;0dp&quot;
                  android:layout_height=&quot;wrap_content&quot;&gt;
  
                  &lt;TableLayout style=&quot;@style/TableLayoutFieldGroup&quot;&gt;
  
                  &lt;/TableLayout&gt;
              &lt;/ScrollView&gt;
          &lt;/LinearLayout&gt;
      &lt;/FrameLayout&gt;
  </code></pre>
  <p>However, it works perfectly when I use android:layout_width=&quot;match_parent&quot; instead of android:layout_width=&quot;0dp&quot; for the ScrollView.   I tried android:layout_width=&quot;0dp&quot; because Android Studio keeps recommending it.</p>
  <p>Could anyone offer a tip on this?</p>
