View 2 Replies View RelatedI am new to Android development and have been following the tutorials available on the Android website. I am currently on the section of tutorials for Views, specifically the one for Grid Views: Hello, Grid View Tutorial.I am having trouble understanding how views are made through an adapter. I understand that you must override the getView() method in your adapter class and in this method is where you define how your Views are set up. What I don't understand is where does getView() actually get called? Perhaps I've got the wrong kind of mentality here, but in the code below (the Grid View tutorial) I don't see any calls to getView() (or any other things used in the adapter class such as getCount()).

This question occured to me while programming a Android application, but it seems to be a general programming question more.
The situation is, I am extending (subclass-ing) an class from a library, and overriding a method. how do I know if I should invoke the method of super-class? and when? (in the beginning of the overridden method or in the end?)
For example, I am overriding the method "public boolean onCreateOptionsMenu(Menu menu)" from class "Activity" in Android platform. And I saw someone write "return super.onCreateOptionsMenu(menu)" in the end of the method, in an example. But how do I know it should be done this way? and it is correct or not? what's the difference if I begin my method with "super.onCreateOptionsMenu(menu)"?
I've configured local service under some app i wanna know how could i invoke methods on the activity, through the service in a synchronous way for example the service invoke a method inthe activity and waiting for for result(synchronous) from it.
View 2 Replies View RelatedI have a Spring Security (form based authentication) web app running CXF JAX-RS webservices and I am trying to connect to this webservice from an Android app that can be authenticated on a per user basis. Currently, when I add an @Secured annotation to my webservice method all requests to this method are denied. I have tried to pass in credentials of a valid user/password (that currently exists in the Spring Security based web app and can log in to the web app successfully) from the android call but the request still fails to enter this method when the @Secured annotation is present. The SecurityContext parameter returns null when calling getUserPrincipal().
How can I make a request from an android app that can enter a Spring Security secured webservice method?

View 1 Replies View RelatedHow does BaseAdapter communicate with its ListView? I was wondering how the BaseAdapter.notifyDataSetChanged() method notifies the attached View that the underlying data has been changed and it should refresh itself? When creating a BaseAdapter you attach it to the View with.So the ListView then knows it's adapter to get list elements. But you never tell the BaseAdapter what ListView it is attached to. So when you call BaseAdapter.notifyDataSetChanged() how does it reach the View to tell it to refresh itself?

In Android 1.6 and 2.0 the BaseAdapter class has apparently been modified to throw an exception when it sees the Adapter.getCount() method return a number different than what it picked up when BaseAdapter.notifyDataSetChanged() was called (at least I did not observe this behavior in pre 1.6).
So now the question is, when should one call notifyDataSetChanged() or more importantly, when can the count in the Adapter be safely changed?
Consider the case of an app with a background thread delivering data to a BaseAdapter at a rate faster than the ListView responds to notifyDataSetChanged(). Because notifyDataSetChanged() is a synchronous call and the ListView updates are taking place sometime in the indeterminate future on the UI thread, how can an app know when it is safe to change the adapter count?
If the app changes the count while the ListView is updating itself the exception will be thrown (and there is no way to catch the exception).
Is there a way to know when it is safe to change the count in the BaseAdapter?
I am using BaseAdapter for displaying the list. This list is fetched by calling a Web Service. At a time only 20 records are returned. Now, when the scroll of the BaseAdapter reaches the last record then the application should fetch more records from the server.
So, what I want to know is how to know the scroll position or some other way of knowing that the last record has been reached so fetch more records from the server. I don't want to implement the next and previous button on the screen.and so am trying to implement it in this manner.
In my android application I have custom listview with an image and textview. In extended BaseAdapter under getView method click events of textview and image are associated with onClick method using setOnClickListener as shown in code below

And

When clicking on image it acutally deletes that entry from List which works fine, but on clicking textview i would like to return the text of clicked textview to main activity but I am unable to achieve this, although I can do this from setOnItemClickListener of this custom listview acitivity.

I started with the sample in the API Demo, using the Efficient Adapter, and it starts like this Code...
I custom the BaseAdapter to show image array with full-screen mode. I want the user can flick the images so I use the gallery class.When a image displays on the screen, a correlative sentence should be showed as well. The issue is the position param in getView function jump abnormally, especially when I flick into more one picture at a time. Therefore the string is showed incorrectly, I don't know why the image still displays normally. Here is my code...
View 4 Replies View RelatedI've tried to describe this problem a few times, but I'll try again.I have a thread (not spawned from the adapter) which updates items in a List that a BaseAdapter child uses to populate its view. I am not adding things in the List from the thread, just modifying content. In any case, I have 6 rows visible at first on the screen. The thread pulls data from the network and updates them in 0, 1, 2, 3, 4, 5 order. However, when 0 is updated, 5 mirrors its data on the screen briefly, then 1 is updated, 4 mirrors it, 3 is updated, then 4 is reloaded correctly, then 5, then 6. I am using the view holder/ convertView pattern correctly, as far as I can tell.How many views are created by default for an adapter? My guess is 3 based on what I see. Then, when getView() gets to index 4, 5, or 6, it correctly creates more Views and populates the right data. Anyone ever seen anything like this?
