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!

i'm making an n-puzzle and already have a gridview with one blank image in the bottom-corner in the right. My goal is now to shuffle the images in the gridview and make a game of fifteen. As beginning programmer in android i have little knowledge of the platform and would apreciate tips and tricks or hints of how i must handle this problem.
I already know that the .setTag() command will be very handy for this problem, but can't seem to find informationblogs or sources on how to use it properly and how to handle this problem.
with kind regards,

I don't normally whine this much, but this problem is really painful.
I've been searching for an answer since 4 months and I still don't know how to do this. I taught myself Android from square 1, but this is 1 problem I just can't get around my head.
I've asked at least 20 questions on SO, half got down-rated, the other half got no answer.
I've checked at least half a dozen libraries, spent days to try and integrate it in my app, but nothing has ever worked.
These were the most promising ones:
https://github.com/matshofman/Androi...Reader-Library
https://github.com/ahorn/android-rss
Took hours to integrate and I never felt real sorrow until I was unable to get anything to work.
If you know how to integrate an RSS feed in an app, please help me out! It's the one thing that's stopping my app from becoming the best in it's field. I reckon I would retain twice as many users if I could just have this. A working example is all I need. I've never even seen ONE. I don't how the News apps do it, it's practically magic for me.
I just want a Listview that shows the title, on clicking and item the description opens up. The rest I can do myself. Any working example will do.
Please Help.
If you haven't figured it out by now, I have made a simple library for this exact reason. The current ones are outdated and hard to customize. Try this one and let me know if you need help. The readme should walk you through basic set up.

You may want to check out this new powerful RSS library I wrote:
https://github.com/Pkmmte/PkRSS
It's very easy to use, extremely customizable, and supports most feeds. For example, the following code loads a specific url in the background:
PkRSS.with(this).load(url).async();
And then you can get the list of feeds loading in that url:
List<Article> articleList = PkRSS.with(this).get(url);
You can then use that ArrayList in your ListView to populate it. Easy, right? :D
I did search the internet to find an answer to my questions but there are no websites that did help me, so I hope someone can! Thank you in advance and have a nice day :-)
So these days I've been busy to get more into the Android Design guidelines and to learn more about it and how to implement it in my future applications. This is the main website I use to see what the guidelines are: http://developer.android.com/design/index.html. Great website but there are a few small things I just can't find in the dev guide or somewhere else. I just don't know how to implement some (simple) UI elements.
Can someone provide me code snippets of the following questions? (I want to know how to do it as simple as possible, how Google ment it!) It can help other (starting) developers too!
My main question is, are there special elements to achieve these things? As they are the key element in Android 4.0 it should have this things as some standard right?
1) Android 4.0 is using titles with dividers a lot in there new theme and it's looking great. But I can't find how to do implement this element simple like it should. What I want to know is how to make this blue title text with the grey looking divider underneath it look at this picture:
2) How to make section dividers in general? Like this image:
3) How to make a list with section dividers and give a list-item a 2-line explanation under it's name like this:

In most cases how you are going to have to do it is create a custom layout. I tried recreating the look of the people application this way. for the most part the look you are going for is similar to the PreferenceActivityview. That gives you the look of the last image and probably how it was done in the People application with some extra programming. I just found it easier to create my own layout though instead of trying to mess around with that.
To my knowledge there is nothing in the api to create what you are looking to do easily and custom layout are going to be the way to go.
the custom dialog layout like you show in the beginning is very simple to do so if you dont know how to do manipulate layouts I would start there. look up the android color swatches to get the color of that blue
Edit
another thing you could do is look through the People source code and see how they did it but it will probably be more of a pain than what its worth when you can just do a layout
is there a simple/native way to implement paging/pagination on scrollviews?
By simple, I mean with a short piece of code mainly using classes from Android SDK, like, when programming on iPhone, writing "pagingEnabled = YES".
When I was looking for the topic on the Internet, I saw people putting pieces of code about that matter, but these pieces of code were very large, and I can't help myself to believe Google did put a simple way to do it in their SDK. I also think that the code to implement it could be much easier than what I saw when looking for it. I'm currently working on it, but in the meantime, if anyone know a easier way to do it, I would be delighted to know about it.
Thanks for reading!
I think that there is not a fast solution to do this.
But what you can do is to take the gallery component and override the layout. The gallery component has paging :)
Another solution could be:
Horizontal Pager - https://github.com/ysamlan/horizontalpager

Hope this helps...
As the title says, how can I do this?
I've looked but can't find the answer.
It's really annoying me now.
This is for my file browser, I've tried using Collections.sort() on the array that gets added to the ListView but that didn't do anything!
Help :'( :'( :'(
