Listview itemupdating

that is because, when we deal with threads, we would not be able to access the android UI elements, to overcome this problem, and similar android has a special type of class know as Aysnc Task. Array List; /** * Created by khan-pti on 01/04/2015.

You may be thing, why don’t we use, the java threads, etc.

In my case the Edit item template is a custom layout and button is inside the layout.

Home Screen (Main Activity.java) Our home screen java class contains code that responds to the onclick event. Here is the xml representation of the class, you clearly see, it contains list view. Use loop to access each object, which can be used by instance of Flowers class and eventually we add the Flower’s object flowers to the Flower List. Secondly http client is no more updated, where as http URL connection will be updated further since android development team is working on this. It is therefore on the most important topic that each and every programmer should know to develop an efficient android application.

Once the button is clicked, we will be prompted to the activity. Flower Adapter class: Flower Adapter class it used in order to fetch data from the class and inflate data into the listview the way we want. package com.example.khan_pti.mfetchdata; import android.content. Http package com.example.khan_pti.mfetchdata; import In this tutorial we have simply shown a text in the listview, where this can be further enhanced by adding images , and other text views to make it more complex and more informative.

All the Find Child controls are found and values returned.

" Select Command="sp Site Invite" Select Command Type="Stored Procedure" Insert Command="INSERT INTO Friends(Request Sender User ID, Friend First Name, Friend Last Name, Friend Email) VALUES ( @User , @First Name, @Last Name, @Email)" runat="server"Very strange that Item Command wasn't mentioned in any other sources I've been perusing the last couple of days.

But when user clicks on the update button, it doesn't fire the Item Command event handler.

When the control is loaded dynamically, should I have to register the event handlers again?

Once the data is fetched from the server from using http URL connection we simply parse the data, store in in list array, and then populate our list view with data. Explanation to the code: Make a new instance of JSONArray (), Passing the data received as an argument. Http URL Connection Here we could use http client connection as well, but since android development team recommends using http URL connection, therefore we use URL connection method to connect to the server. Most of the application rely on online server, in order fetch data, authenticate in fact application need to be connected to internet all the time to get user the latest updates.

When the user clicks on the button on the home screen, activity will be prompted, and our background task that is explained below will be executed. Since we get the data in json array , we will need to first parse the data, in order to use it . In your case, what ever data you are getting you may do it accordingly. Conclusion: Most of the android application, uses Listview, plus json, to fetch data .

When I click the update button in the Edit Item Template it doesn't trigger the Item Command event. I have a sneaking suspicion it has to do with binding the grid on a postback.

Edit Index = -1; Bind List View(); And finally, my binding method: protected void Bind List View() When I click the edit link, the List View goes into edit mode like it should. One note: This List View is in a user control within a sharepoint webpart, so the user control is dynamically created.

Button; public class Main Activity extends Action Bar Activity class The next class in our list is that contains the main functionality of our application. Json Parser: In class with in our inner class, on Post Execute() method the data is parsed, and then added to the flower list. I will be only including the names of the flowers to make it short, and easy for you. We don’t have much to do, here accept for couple of lines added for permission, and declaring activity, in our case Fetch Activity.
