title: How to set default text in TextView to see it in the layout preview while binding?
body: <p>So I would like to see my layout preview with the fields filled with something like default placeholders but if I use bindings the settext attribute is already used and the fields are showing empty since there is no info from the models yet.</p>
  
  <pre><code>&lt;TextView
                  android:id="@+id/tv_user_name"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:layout_gravity="center"
                  android:layout_margin="5dp"
                  android:gravity="center"
                  **android:text="@{showBlueportSpotViewModel.name}"**
                  android:textAllCaps="true"
                  android:textSize="20sp"
                  android:textStyle="bold"/&gt;
  </code></pre>
  
  <p>I tried this:</p>
  
  <pre><code>android:text="@{showBlueportSpotViewModel.name ?? @string/blueport_placeholder_name}"
  </code></pre>
  
  <p>but I still see the view empty.</p>
  
  <p>Do you guys any workaround? I guess once a workaround is found, it can be used to ImageView and src for example and etc..</p>
  
  <p>Thank you!</p>
