title: Get the height of a generated view
body: <p>I'm trying to get the height of a <code>StackLayout</code>. This layout is filled with data from my backend, so it's not always the same height. I tried <code>view.getViewById(parent, selector).effectiveHeight</code>, but it keeps outputting <code>0</code>. </p>
  
  <p>My XML file looks a bit like this:</p>
  
  <pre><code>&lt;Page&gt;
      &lt;ActionBar title="..."&gt;&lt;/ActionBar&gt;
      &lt;GridLayout rows="*, auto" columns="*"&gt;
          &lt;ScrollView row="0" col="0"&gt;
              &lt;GridLayout rows="*" columns="*"&gt;
                  &lt;StackLayout id="TARGET" row="0" col="1"&gt;
                      &lt;StackLayout *ngFor="let x of y"&gt;
                          &lt;FlexboxLayout justifyContent="space-between"&gt;
                              &lt;FlexboxLayout&gt;
                                  &lt;StackLayout&gt;
                                      ...
                                  &lt;/StackLayout&gt;
                              &lt;/FlexboxLayout&gt;
  
                              &lt;FlexboxLayout justifyContent="space-between"&gt;
                                  ...
                              &lt;/FlexboxLayout&gt;
  
                          &lt;/FlexboxLayout&gt;
                      &lt;/StackLayout&gt;   
                  &lt;/StackLayout&gt;
                  &lt;StackLayout col="0" row="0"&gt;
                      ...
                  &lt;/StackLayout&gt;
              &lt;/GridLayout&gt;
          &lt;/ScrollView&gt;
  
          &lt;StackLayout row="1" col="0"&gt;
              ...
          &lt;/StackLayout&gt;
      &lt;/GridLayout&gt;
  &lt;/Page&gt;
  </code></pre>
  
  <p>Thank you in advance!</p>
