I'm using a view that supports list inside another list. I want to multi-thread it and also use Endlessadapter with it.
This view, has its own adapter. How do I pass the data, that I get to this adapter to Endless adapter. All are in the same name-space. I don't think so I'm very clear with the question, but I'm also rather confused with my own architecture. I'll shape the question a bit better if I get some help. Thank you!
I think you should use:
Expandable ListView adapter

I have a very simple question. I'm working on an Android application where I make use of Simple Adapter for ListView. Now I need to append items to this ListView dynamically. I know it is possible to do so in case of Array Adapters.
It is done as follows:
adapter.notifyDataSetChanged();
Is there any equivalent for the same in case of Simple Adapters? I couldn't find much relevant links regarding this on the net.
Kindly help.
Thanks in advance!
I think not, but you always can create a new SimpleAdapter and call setAdapter again with the new adapter.
If you are going to add/remove elements you, probably, need some other adapter not a SimpleAdapter. Because they say in the docs that SimpleAdapter is 'An easy adapter to map static data to views defined in an XML file'
Does anyone have a good tutorial for implementing onItemClick() for a ListView populated by a custom ArrayAdapter?
I'm struggling with how Android is recycling views, and how to affect the layout of the selected view (which is a RelativeLayout). The way I've implemented it, I'm just doing a simple background colour change, but everytime I choose a row, when I scroll the ListView there are other off screen items selected too.
Any ideas?
Have a look to this answer. Custom code of ArrayAdapter.getView() (where view recycling is done) might be useful to you, I was trying to achieve something similar and it worked for me at last :)
You can find lots of good examples of the custom Listview with Adapters.Some of the Examples are listed below:
(1)custom-listview-android
(2)android-custom-listview-with-image-and-text
(3)Custom Array Adapter
Is it possible for setting more than one adapter to a single list?
For example
list.setAdapter(adapter1);
list.setAdapter(adapter2);
Maybe you can try attaching multiple adapters to a single adapter like here
android attaching multiple adapters to one adapter
Or maybe this

if I understand what you need it for correctly
Pls update why you want it for so we have a better understanding
I would like to use an adapter to synchronize a List of data with a vertical LinearLayout where it will be displayed. The problem I'm having is that non-AdapterView View Groups (Like LinearLayout) do not have the setAdapter() method. Can anyone suggest a way of achieving this?
Instead use a ListView with SimpleAdapter or SimpleCursorAdapter. Both adapters are very flexible for all kinds of customization based on your data.
I want to do something like mylistview.setElementsofView(0).getElementById.setColor("black");
currently the only way I know of doing this is setting up a custom list view adapter, setting up constructors, do conditional checks to see if view is populated, then do stuff in that view
this seems very convoluted, when other parts of the listview are so easily accessible.
is there some inherited function I can access in listview to allow me to access the elements of a particular view without a custom adapter?
Thanks for any insight
The short answer to your question:
is there some inherited function I can access in listview to allow me to access the elements of a particular view without a custom adapter?
unfortunately is no.
Why do you think setting up a custom adapter is so convoluted? Just make the customized adapter class a nested class within your activity. Most likely, you'd only be looking at overriding the getView() method. In the end, you'll spend a lot less time doing this than looking for a "simple" solution.
What about
myListView.getChild(index).setColor("black");
