Android - Cursor Loader

I've been trying to use cursor loader.I started following this tutorial http://responsiveandroid.com/2012/03/19/using-an-android-cursor-loader-with-a-content-provider.html but could not understand.tutorial put me in chaos.

As far i know cursorloader is an adapter,adapter job is go to content provider take data then put the data in to view.

What does content resolver do ?

Android document says SimpleCursorAdapter is depreciated and says to use cursor adapter,this is the tutorial that i was talking http://responsiveandroid.com/2012/03/19/using-an-android-cursor-loader-with-a-content-provider.html

Here he uses both simplecursoradapter and cursor loader.Why is that ? Can any one explain me ,how to use cursor loader ?

I think you can still use SimpleCursorAdapter. Looking at the documentation, it looks like the old constructor is deprecated but you can use another constructor which is this one:

SimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) Standard constructor.

More details here: http://developer.android.com/reference/android/widget/SimpleCursorAdapter.html

You are conflating two different things.

A cursorloader gets that data from your data source and loads it into a cursor then manages the cursor. A cursor is basically an in memory data storage construct.

An adapter takes the data from the cursor (or array or list) and puts into your display layout to be viewed.
