I need to display a total value of a query in mysql in my app using json.
A simple thing until I just think it does not find a solution, I always think tutorials that teach the list using a listview, but only need to display in simple TextView.
The PHP part is ready.
Can someone give me a way?

I want to sort an expendable listview dynamically. Could someone tell me how to accomplish this?
I've tried sorting the group name but then the child elements don't get sorted.
I think we would need more details about the code, without the code it's hard to tell but anyway here is a link to some code maybe it will help you:
https://github.com/commonsguy/cwac-touchlist
Basically what I did was sort it using custom comparator methods.
So i want to make a list that has a number of items on the list but when a item is clicked i would like it to expand in the list to revile more information
i have done something similar with java script before but searching google isnt helping me :(
Does any one know a way i can achieve this or will i be stuck using multiple pages.
I think you are looking for Expandable listView. You can check the example here
Hope this may help u..
I know my question isn't formulated well.
I'm adding items to an ArrayList downloaded from JSON file and the ArrayList is passed to a ListView.
So what is my problem?
After displaying the data from the ArrayList i wan't to add new items to it so they can be show right after they are added. I managed to do this by setting the Adapter for the ListView again after the data is added.
Displaying the new items should look smooth but instead it looks very sluggish and i know it's not the right way to do this.
I've searched about this problem but couldn't manage to find anything, so for anyone answering
Thanks in advance.
Its very easy
You need not to set the data adapter again to the listview..
instead
call after you downloaded the new data
listView.getAdapter().notifyDataSetChanged();
this function will tell the view to be build again.
In addition Check the following link. here i mentioned a complete code to use listview properly.
Using this we can achieve any listview behavior. We can embed animation also.
Change ListView background - strange behaviour
Hope this help :)

May be FastScroll fits to you?
http://developer.android.com/reference/android/widget/AbsListView.html#setFastScrollEnabled%28boolean%29
You can get it by using Database,manage a table to store parsed data and then display data in listview by fetching it database table,
please refer the link for more about database in android
http://developer.android.com/guide/topics/providers/content-providers.html
I tried to do the same and i ended up putting a list view and a textview into a frame layout and then using touch positions in conjunction with list.setslection() to focus...worked for me ! more here: Replication of Apple's Search in Android
I agree with Sergey Glotov, regarding Fastscroll, please take a look at sectionIndexer interface.
Maybe these links(eg1 and eg2) will help you.
