I have a requirement that I need to display as many elements as possible in listview.
I have some 50 elements in my listview , so to display many elemnts I decided to split the listview in two parts , means half of my activity screen will display some elements and second half will display some more elements....
Please help if its possible to draw the listview in two parts, if not please let me know if ther's any aletrnative.. The data in a listview is dynamic..
I am using Android version3.2..
So it sounds like you need to implement multiple listviews within a single activity. This stackoverflow post is probably what you're looking for.

I am really confused, which among GridView, Tableview or multiple listview to be used to develop a UI as shown in below image.
I don't know how much list data (categories and its sub categories) is in web. It is dynamically added from wed, and sent to my android app.
Please suggest me, what view is best for developing above UI.
Note: I want to make it programmatically.
Thank you in advance for your co-operation.
Keep in mind that the image you have shown as an example is quite large and such an implementation would make for a cluttered UI on smaller screen sizes. That being said, the example you provided could be achieved in Android by using a GridView. Each major category (Automotive, Jobs, etc.) would be a grid item, with the sub element implemented as either a TextView or even a ListView within the grid item. Something like this:
As both #PedroHawk and #bryan mentioned, you could also use an ExpandableListView; in this scenario, the major categories (Automotive, Jobs, etc.) would be header items and the sub elements would be children of the header. Something like this:
However, with this implementation you would be limited to a one-dimensional list - that is you would not be able to have major categories next to each other as shown in your example.
With both of these implementations (ExpandableListView and GridView) you can dynamically add more elements as you receive data.
Like PedroHawk said, ExpandableListView is an option. But also consider because of the screen size, you may not want to try and port the UI directly over. What about a single ListView with just the main categories and the user can drill down?
Is it possibly to take a single list view which in portrait view would normally be displayed normally, but when in landscape mode I wan the list view to be split into to two entities one next to each other.
I have attached an image to try and explain what I would Like.
How can I achieve this without having to put two separate interviews next to each other?
You should use a GridView. This is very close to a ListView More information here.
Use android:numColumns="2" for set the column number.

Hope is what you want.
I was wondering how to implement the listview like the android market.
in the right hand panel a listview is divided into the two rows. This is very useful because it saves lot of space and user can look at almost double items in the listview at a time. how can I implement this ? any suggestions?
you can use GridView instead of ListView of two columns..
1. GridView
2. GridViewExample
Sample design :
The Android Market also uses the ViewPager to scroll between the pages. Here is an example on how you could implement it.
There is another question that is related to this one.Check the folling link, it might help you:
How to display a two column ListView in Android?
Modify you *.xml file to get what you want.
Good luck!
If you want to do this using listView, then each item (row) in the list view should consist of two views. You can do this using a relative layout (or linear layout) with two items side by side.
You can also implement this using a gridview having two columns.
I am currently making an android application which need to present a lot of information from different arrays. On each horizontal line there's gonna be four different texts and then I need to be able to scroll through all information displayed. I know ListView is one way to go, problem is I dont know how to use four text views horizontally in a ListView. Any tips or help to get the best way to present the information would be grealy appreciated.
Basically like this:
You have to extend ArrayAdapter and override getView() of Array Adapter.
I have created a custom adapter to display a list, there is an image that is displayed in each row ( the image is the same for all rows, except using an array i am assigning it different values depending on the position). An xml file defines the relative layout that i am using. My problem is that i can either get the entire row to be clickable or nothing at all, I only want this image to be clickable, instead of the entire row. How would i be able to do this ? i am new to android and am pretty much following different tutorials trying to create my list. Any help would be appreciated.
layout is like this :
TEXT:
[Image]
TEXT:
thats wat a row looks like...getting two texts from two different arrays and shows it, a third array is used to link to the image. I just want this image to be clickable instead of the entire row.
Thanks
Android's list component manages clicks per row. This makes it very difficult to achieve what you want to do. Two solutions come into mind:
1) If your list is never very long you could simply use linear layout and scroll view to build the list. This approach won't work if you fill in the list dynamically and you can't be sure that there won't be a very large number of rows as it would use too much memory in that case.
2) Other option is to use ListView but make your text components and images different view types in list ie. break you row into three.
That can be achieved overriding list adapter's getItemViewType(int)
http://developer.android.com/reference/android/widget/Adapter.html#getItemViewType(int)
In this approach you can make the image rows clickable but the text rows not.
