Android Data Binding: visibility on include tag

Question

As per http://developer.android.com/tools/data-binding/guide.html#imports, we can have such simple expressions in visibility:

<TextView .. android:visibility="@{user.isAdult ? View.VISIBLE : View.GONE}"/> 

But when I try to do the same in an include tag, like so:

<include android:id="@+id/image_layout" layout="@layout/image_layout" android:visibility="@{notification.notifType == 0 ? View.VISIBLE : View.GONE}"/> 

Then Studio not only shows the expression in red, but upon building it gives the following error in the auto-generated binding class:

Error:(138, 29) error: cannot find symbol method setVisibility(int)

Here's where the error occurs in the auto-generated binding class

// batch finished if ((dirtyFlags & 0x3L) != 0) {     // api target 1     this.imageLayout.setVisibility(NotifTypeNotificatio1); } imageLayout.executePendingBindings(); 

Answer 1

I imagine what you are trying to do would look something like this:

In the layout you are including, specify a boolean variable and bind it to the desired view's visibility

<layout xmlns:android="http://schemas.android.com/apk/res/android">      <data>          <import type="android.view.View"/>          <variable             name="isVisible"             type="boolean"/>      </data>      <ImageView         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:visibility="@{isVisible ? View.VISIBLE : View.GONE}"/>  </layout> 

Then In your calling layout bind your value

<include     android:id="@+id/image_layout"     layout="@layout/image_layout"     bind:isVisible="@{notification.notifType == 0}"/>

Try:

this.imageLayout.getRoot().setVisibility(NotifTypeNotificatio1);
