Android Data Binding: visibility on include tag

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();

Solution 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}"/>

Solution 2:

Try:

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