What is Layoutinflater ?
LayoutInflater is a class (wrapper of some implementation or service), you can get one:
LayoutInflater li = LayoutInflater.from(context);
How to use Layoutinflater ?
You feed it an XML layout file. You need not give full file address, just its resource id, generated for you automatically in R class. For example, a layout file which look like:
saved as /res/layout/my_layout.xml.
You give it to LayoutInflater like:
View v = li.inflate(R.layout.my_layout,null,false);
What did Layout Inflater do ?
That v is now a LinearLayout object (LinearLayout extends View) , and contains a TextView object, arranged in exact order and with all properties set, as we described in the XML above.
TL;DR: A LayoutInflater reads an XML in which we describe how we want a UI layout to be. It then creates actual Viewobjects for UI from that XML.
