Our RecyclerView.Adapter is very inefficient #8

Open murraycu opened 9 years ago

The RecyclerView.Adapter uses a Cursor to use the data from our ContentProvider: https://github.com/murraycu/android-galaxyzoo/blob/master/app/src/main/java/com/murrayc/galaxyzoo/app/ListCursorAdapter.java

But it's horribly inefficient, calling notifyDataSetChanged() whenever there is any change in the cursor, making the RecyclerView do work for each item all over again.

There's still no obvious way to do this correctly with RecyclerView: https://github.com/googlesamples/android-RecyclerView/issues/4#issuecomment-87246333
