        }
    )
}

Step:2

You can use the in the image view for loading dynamic images based on input, refer below:

<ImageView
            android:id="@+id/imageView4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
             set_expense_category_image="@{expense.expenseCategoryName}"
            app:layout_constraintBottom_toTopOf="@+id/view"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="@+id/imageView5"
            app:srcCompat="@drawable/ic_baseline_fastfood_24" />

You can use it in such way:

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_padding="20dp"
    android:scaleType="centerInside"
    android:src="@{model.isActive ? @drawable/activated_icon :@drawable/non_activated_icon}"/>
