As well known, ConstraintLayout is now a most popular and efficient layout on android development. But for using it's attributes, you gotta import "xmlns:app" first. It's very annoying when you need to creat many xml files with ConstraintLayout. How do I creat xml files with this scheme("xmlns:app") automatically? I need a template instead of importing it manually.
The best in my opinion is to use Live Templates in Android Studio. It lets you create code snippets and add them with matter of seconds into the code:
And here is the example with XML:

So what you can really do is put this:
<androidx.constraintlayout.widget.ConstraintLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent">
</androidx.constraintlayout.widget.ConstraintLayout>
in Android Studio -> Preferences -> Live Templates
The simple way is go to File -> New -> Edit File Templates.. -> Click + button -> paste your ConstraintLayout layout here -> Click ok. Done.
To use it: Right Click -> New -> MyXML (your xml file name)
Here it is. Go to Setting -> Menus and Toolbars -> Project view popup menu -> Change position of the From Template by press Alt + up (Alt + down), click ok to apply it
