With these it helps Regardless of the complexity of your layouts and processing attach to your cells, I will recommend you to use single adapter for each list.
Just a small picture to illustrate the mainly operation of the RecyclerView : RecyclerView operation

Scrolling large lists of Cursor-based adapters is faster than much smaller lists of in-memory adapters

Hope that helps I have a similar thing in my application, except I only have json backed ListView and I also have about 30 items in it (with data constantly changing and animation playing to reflect changes). It would be much more easier to detect a problem with some provided code from your side, but here are couple of tricks you can sue for optimization.
Reuse convertView that is passed to you as one of the parameters in getView method, it really speeds up the scrolling.

   TextView text;

android attaching multiple adapters to one adapter

it should still fix some issue I have been using the SeparatedListAdapter which is very well known and works perfectly, but it seems that I cannot use the addSection() to add a SimpleAdapter, because the application is terminated. I'm providing some code to show you what I'm trying to do and get some guidance in order solve this issue. Please let me know if you need any other piece of code or anything: , Added this line:
setListAdapter(_sla);
_sla.addSection("Results", _resultsAdapter);

Issue with zope.component subscriber adapters adapting multiple objects


Tag : python , By : WellBeing

I wish this helpful for you You are listing subscribers. Subscribers are notified of all things that implement the interface(s) they are interested in.
C is a subclass of B, so the B subscriber is interested, and will be notified. The fact that C implements a little more is of no concern to the B subscriber, as the object will implement at least the B interface.
>>> gsm.registerAdapter(AB)
>>> gsm.registerAdapter(AC)
>>> from zope.component import getAdapters
>>> for adapter in getAdapters((a, c), Interface):
...     print adapter
... 
(u'', <__main__.AC object at 0x104b25a90>)
>>> class AnotherAC(object):
...     implements(Interface)
...     adapts(A, C)
...     def __init__(self, a, c): pass
... 
>>> gsm.registerAdapter(AnotherAC, name=u'another')
>>> for adapter in getAdapters((a, c), Interface):
...     print adapter
... 
(u'', <__main__.AC object at 0x104b25ed0>)
(u'another', <__main__.AnotherAC object at 0x104b25a90>)

Hexagonal Architecture / Ports & Adapters: Application Configuration with multiple driver adapters

will be helpful for those in need This is an interesting question.
From my point of view, trying to be faithful to the pattern explained by its author, although it would also be posible to run more than one driver adapter for one driver port, the "app as a whole" (let's call it system, since the app is the hexagon) is an instance of a driver adapter running on each driver port of the hexagon, and a driven adapter implementing each driven port.
