data binding - Android dataBinding - how to use bool resource to trigger visibility of layout -

-

i have bool.xml file in android looks this:

   <?xml version="1.0" encoding="utf-8"?> <resources> <bool name="showads">true</bool>     </resources>

now have layout.xml file uses databinding. want show or hide visilibity of adview based on boolean showads defined above. far have this:

  <com.google.android.gms.ads.adview         android:id="@+id/adview"         android:layout_width="wrap_content"         android:layout_height="wrap_content" android:visibility="@{@bool/showads ? view.visible:view:gone}"         ads:adsize="banner"         ads:adunitid="ca-app-pub-1234567/34343">

but not compile. how can boolean decide if ad should show or not ?the syntax wrong.

correct syntax of condition view.visible:view:gone

android:visibility="@{@bool/showads ? view.visible:view.gone}"

and need import view in data section:

<data>     <import type="android.view.view"/> </data>
