It's a long post. Can you shorten it to highlight exactly where the issue is?

Thank you for reply
What found in code above is show all Restaurant items name,city,address
in list view in one activity call main activity
What actually need is to add button in layout main activity and when
press on button for one click show one item
when press click again show another item restaurant
until i get all restaurants from json file
depend on button click listener
if button press 3 time get three restaurant
in case of json file have Restaurants
Meaning i need to customize code above to show every click button one item

ahmed, i still do not understand what you mean.

Please reply showing just the method that is not doing what you want, or that needs modification. Give example input/output, and explain what it should be doing. With that information, i might be able to help.

List listTitle = new ArrayList();

for (int i = 0; i < venuesList.size(); i++) {
listTitle.add(i, venuesList.get(i).getName() + ", " + venuesList.get(i).getCategory() + "" + venuesList.get(i).getCity());

Can you provide the actual result and your expected result?

I would like to help, but i am no expert in this. I am still learning much of the basics. So, i would like to see a simple code example with the actual and expected results, to help keep it small enough for me to understand. Of course, someone else might jump in to help as well.

What I see so far is this: You have a URL, and you submit that to its website, which returns some data. This is somehow converted into a JSON representation of a list of restaurants. Correct?

Now. Do you want that to do something else? Like return only one restaurant? Or do you want to take the list of restaurants and build a user interface where you can display the restaurants in the list, one at a time?

Or do you want something else entirely? Right now nobody understands your question; you have a big lump of code and a wish-list which might relate to the code in some way, but how?

Okay. So you want some different code which takes that list and displays it one item at a time.

I'm not an Android programmer but some of the others on this thread are, I think, so I will leave that to them.

Oh, now i understand what you want. I have not really done this before, so i am not sure how much i can help. I think you need to use a DataAdapter to control what data is available to be shown.

Do you want it to male a call for each click, or do you just want it to make the current call for the list and then display one at a time?

If the latter then store the JSON somewhere (my Android is a bit limited) along with the current displayed index and onClick of the button read the next one in and display that.

So I can see three chunks of work there.
1. Store the JSON and an index
2. Handle the onClick event
3. Show a restaurant

Each of which should be fairly simple to look up how to do.

I write this lines of code under button but it not working why

You could storage the parsed ArrayList, make a global variable for counting the number of times that the button has been clicked.

Please use code tags when posting code of any length. I've added them for you this time, but please remember to use them next time.

"it's not working" is not a useful problem description. What, exactly, were you expecting the code to do, and what, exactly, does it do instead?
