How to set visibility for include layout in databinding

Although Android offers a variety of widgets to provide small and re-usable interactive elements, you might also need to re-use larger components that require a special layout. To efficiently re-use complete layouts, you can use the <include/> and <merge/> tags to embed another layout inside the current layout.

Reusing layouts is particularly powerful as it allows you create reusable complex layouts. For example, a yes/no button panel, or custom progress bar with description text. It also means that any elements of your application that are common across multiple layouts can be extracted, managed separately, then included in each layout. So while you can create individual UI components by writing a custom View, you can do it even more easily by re-using a layout file.

Solution:

dataBinding.regPhone.getRoot().setVisibility(View.GONE);

dataBinding.regEmail.getRoot().setVisibility(View.VISIBLE);

On the top layout, declare the boolean or an observable field whose value toggle the visibility of the included layout. Then remember to give the included layout an id else it wont work

<?xml version="1.0" encoding="utf-8"?>

<layout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools">

    <data>

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

        <variable

            name="show"

            type="Boolean" />

    </data>

    <androidx.constraintlayout.widget.ConstraintLayout

        android:layout_width="match_parent"

        android:layout_height="match_parent"

        tools:background="@color/colorPrimary">

        <include layout="@layout/progress"

            android:id="@+id/progress"

            android:visibility="@{show?View.VISIBLE:View.GONE}"/>

    </androidx.constraintlayout.widget.ConstraintLayout>

</layout>
