DATA BINDING + QR-SCANNER + QR-GENERATOR

DATA BINDING:

Whenever the developer wants to interact with the UI element, it can be achieved by infalating the Activity or Fragment layout, bind the UI element through findViewById or using ButterKnife binding technique and finally allocate the data value to element.

At Google I/O 2015, the new binding technology introduced called "DATA BINDING", which helps the developer to remove all boilerplate binding calls as well as having to manually update those views in the code.

Environment Setting:

• Add dataBinding element to your build.gradle file in the app module, which will enable data binding in your project.

android {
    ...
    dataBinding {
        enabled = true
    }
}

• Add root tag in your activity xml.

<?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"
    tools:context="com.example.ali.roomapplication.ui.MainActivity">
    
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="20dp">
        
        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
            <EditText
                android:id="@+id/txt_name"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Name"
                android:text='@{data.name}' />
        </android.support.design.widget.TextInputLayout>
        
    </LinearLayout>
</layout>

Environment Setting:
