Im pulling a list of product objects from a database call and I want to build a ListView of the data in my activity with a non-scrolling header and footer. Each row will consist of a product thumbnail, some data and a button arranged horizontally. I understand that using the ListView I can inflate each row using a separate layout. Most of the examples Ive seen using ListView just show a simple array of strings that fill the whole view of the activity, but most real-world examples will be more complex and I can't find any good examples that explain how all these pieces fit together. Does anyone have any pointers to sample code with a good explanation ?

View 4 Replies View RelatedI have ListActivity to show a custom list. The adapter for this list is a complex layout only known for each row at runtime depending on data gathered in a previous activity. The question I have is simple. I know it takes 4-6 seconds to prepare the adapter for the rows that will be visible (first 10), however I would like to let the user know by means of the empty list functionality or otherwise. At present the ListActivity is launched via a button on a previous activity and when that button is clicked the new activity will not be loaded until the adapter is completed, and the user is stuck with the previous activity until this happens. Code...

I'm new to opengl-es and I wonder how people are able to draw these much detailed OpenGL ES graphics, e.g. on Android OS. It's already hard to draw a single squre, because it's composed of triangles due to the reason that OpenGL ES obviously cannot draw anything else than triangles.
I thought about this approach:
Drawing and rendering an object in Blender.
Export it somehow as array of vertices and an array of colors
Copy this array of vertices into the Java code
Run the code
Or are there approaches to solve such problems in a better way? I do not think that people just "draw" their graphics as array of vertices in the code. I'm sure they draw them anywhere else and import it into the code.
If there is such a solution with Blender, I would be pleased to know how this is solved.
My app connects to the net and populates a ListView. Sometimes nothing will be returned. What is the best way to notify the user the list is empty?
View 3 Replies View RelatedCurrently I'm trying to find an efficient way to handle the following scenario. Please comment on my current implementations and all feedback is greatly appreciated! I have about 7 adapters with data. This data comes from database and some come from xml queries over the internet which are kept static in memory. In my current implementation I re-use one ListView constantly to display this data as requested by the user. Here are the questions: 1. Is this a proper approach? or should I have a ListView for every Adapter?
View 9 Replies View RelatedThis should be a simple question because I couldn't get the answer from Google . I have ListView in a LinearLayout . I need to handle the click event to allow user click on the LinearLayout to trigger some function. I try to add onClickListener to the LinearLayout , and it works only when I click outside of the ListView . How do I let the click event on ListView propagate automatically to be handled by the Listener of the LinearLayout?

I'd like to create a list with an image on the right side of each entry - and preferably have a separate callback if the image is clicked.

View 2 Replies View RelatedI have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

Now my requirement is to create listview inside it. i know we can create textboxes,buttons,dropdown list inside it. but in order to create list view we should inherit our class from listActivity class. is it possible or not if yes then how to achieve this using any interface or what?
Just have a look in the system app contacts --->add new contact, this activity have a listview with different structured views for each row. I could do this by override the "getView" method, but a problem I'm facing is edittext will lose focus when I click on it. What happened when the view enter touch mode?
View 4 Replies View RelatedI want to create a customized ListView (or similar) which will behave like a closed (circular) one:
scrolling down - after the last item was reached the first begins (.., n-1, n, 1, 2, ..)
scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)
It sounds simple conceptually but, apparently, there is no straightforward approach to do this.
I have already received an answer (from Streets Of Boston on Android-Developers google groups), but it sounds somehow ugly :) -
I did this by creating my own list-adapter (subclassed from BaseAdapter).
I coded my own list-adapter in such a way that its getCount() method returns a HUGE number.
And if item 'x' is selected, then this item corresponds to adapter position='adapter.getCount()/2+x'
And for my adapter's method getItem(int position), i look in my array that backs up the adapter and fetch the item on index:(position-getCount()/2) % myDataItems.length
You need to do some more 'special'stuff to make it all work correctly, but you get the idea.
In principle, it is still possible to reach the end or the beginning of the list, but if you set getCount() to around a million or so, this is hard to do :-)
I want to create a better NumberPicker then the one used in DatePicker, I looked at the HTC Sense Alarm clock Roller (Looks like the iPhone Spinner/Roller). I want to create something like that.
I've created a listView that looks right, but I need a way to get the current id of the middle row. ListView.getFirstVisiblePosition() kind of do what I want but it will give me +-1 errors. Another problem is that the scrolling should lock into a certain row when "dying" out. These are of couse related and I hope I can solve this by using a custom ListView, but it's hid in the API
Any thoughts on how to solve this?
What I want to do in one of my tabs in my application is have a ListView of contacts. Though, in that example, the ListView is made from an array of Strings. Is there a way that I can create one of those using the values from an ArrayList?

View 4 Replies View RelatedThis maybe against the way the Android team wants this to work, but if not I can't seem to come up with a way to do this. Basically I have a list view that I want to create a ContextMenu when onListItemClick received. So when the user clicks on a list item I want them to choose the action from a ContextMenu. Anyone have an example of how to do this, I can get it to work with no problems with a long press, but my users are missing the menu and just thinking the ListView does nothing.

I have a ListView that uses Linkify to create a link to another activity in my app. the url looks something like content://com.myapp/activitiy/view?param=blah
This works fine every time.
However, in another view, I'm trying to call some code like this:
CODE:.............
But for some reason this doesn't seem to work. It doesn't trigger my activity (and in fact it blows up if i dont include the setAction() call. How am I supposed to create the Intent such that it acts the same way that Linkify does...?
Now i realize i can setup the extras and then handle it in the activity, but that just seems like duplicated effort.
I was wondering if there was a way to create a ListView with rounded corners in Android...
