Back in the day MotoDev Studio (Eclipse based, put out by Motorolla) had a feature to extract references from your XML into your code. Standard Eclipse with the ADT didn't have this feature but was wondering if it's possible in Android Studio.
So for example given XML:
<Button
android:id="@+id/my_button">
It would generate in your activity's class:
private Button mMyButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
...
mMyButton = (Button) findViewById(R.id.my_button);
}

Android provides a straightforward XML vocabulary that corresponds to the View classes and subclasses, such as those for widgets and layouts. You can also use Android Studio's Layout Editor to build your XML layout using a drag-and-drop interface.
xml file contains information of your package, including components of the application such as activities, services, broadcast receivers, content providers etc. It performs some other tasks also: It is responsible to protect the application to access any protected parts by providing the permissions.
The XML layout file contains at least one root element in which additional layout elements or widgets can be added to build a View hierarchy.
XML tags define the data and used to store and organize data. It's easily scalable and simple to develop. In Android, the XML is used to implement UI-related data, and it's a lightweight markup language that doesn't make layout heavy. XML only contains tags, while implementing they need to be just invoked.
There is plugin to Android Studio called ButterKnifeZelezny, which provides feature you're requesting but only if you're using ButterKnife. You can select what you want to import and so on.
