I have used ArrayAdapter to populate the Spinner. I want to know if it can be done using a SimpleAdapter? Please guide me in the right direction.
Thanks in advance.
If my answer here (including the follow-up comments) is correct, then you may need to add a ViewBinder to the SimpleAdapter. You can google for examples of ViewBinder implementations -- it doesn't seem to be very complicated.
EDIT: You do need the ViewBinder, at least for some earlier versions of AndroidOS (I found it's not needed for 2.2). See the other answer, and perhaps also my blog post about this.

This is one of the implementations that I have the most difficulty in actually finding the best way to solve.
There are a lot of techniques and ways, but the last answers I found did not really seem to me to solve the problem. Another point is that they are usually very old techniques and libraries.
What I want to do is this:
How do I create this ListView with a GridView inside and the screen has infinite height without using ScrollView, so we know that it is not recommended to use ListView within ScrollView.
I am not asking you to develop the code, but rather recommend me the correct architecture that I should use to implement this (ScrollView, ListView, GridView), or memo a library that has new development concepts that can help me.
This question arises because many of the existing responses are too old and have outdated ideas.
I know the question is of a slightly higher level of complexity, but I accept everyone's help.
Thank you very much.
It is very easy to solve this using a RecyclerView.
The documentation is pretty clear and explains all the details necessary for the development of the functionality.
I will leave the necessary documentation links to implement:
RecyclerView
GridLayoutManager
ItemsViewHolder
We know that it is always better to use native components in the development, I recommend, but if you prefer to use a library ready to solve your problem, here are some interesting:
Sticky Headers
recyclerview-stickyheaders
StickyListHeaders
this is probably a repost but I have to do it, because Android versions change so does the code too and because I have already tried every tutorial on the internet. I am trying to make a listview and the child which is going to be multiplicated is a CardView. And I tried too much different code to post, because this taking me already days. So how do I make this with an Adapter? My problem was that it never displayed the content. If you need further information, and you probably do, please comment below. I am very thankful for your help guys!

Is there a way to complete cursor queries off the main thread that update specific fields in a List of objects? I have looked into CursorAdapter examples from the Google Development Library, however, most solutions simply update ListView rows with the queried information, not pre-existing objects.
Is my only solution to query the information in an implementation specific thread, or is there something similar to CursorAdapter for the process I am describing. Thanks in advance! All links appreciated
This is pretty simple in Android by using Loader. Please refer
http://developer.android.com/guide/components/loaders.html
Loader is ideal for this. If you find any issues for implementing this, tell me. I can help you with some samples
I´m a beginner on developing for Android, and I´d like to understand how to create a more complex list view, as probably you saw in Google I/O 2010, so if you have any blog/book/website/sample or anything else that could help me understand this World, it'll help me a lot.
Thanks.
I hope these links helps you:

If you have Eclipse setup with the SDK I'd recommend downloading the api demos from the Android SDK Manager. There are quite a few ListView examples in there.

Try reading the documentation relating to lists and adapters.
Possibly the easiest adapter to get acquainted with is ArrayAdapter.
Don't be afraid of the online documentation, it's really approachable once you get used to it.
