I am using a version of the "Grid View" example from the Android Developers site: http://developer.android.com/resources/tutorials/views/hello-gridview.html And I would like to display images in reach grid randomly and the image position will change in each click. Can someone please give an example of how this might be accomplished (i.e. what needs to be edited)? Thanks!
You need to implement a custom ListAdapter, where you need to check which items are visible and select then a random image which is not visible. Bute note that a total random list will confuse your users. Better sort your images by random and visualizate them same in one instance.

I want to know, can we make list of item that not having same width and stand after each other, like tags in blog website
for example:
shoes, clothes, shock,
burger,
so the item goes next after previous one, but in different width. im trying listview it goes new line every item, if gridview, it consistent width not fill the need.
As I'm in beginner level of android programming, I want to know if we can achieve that?
Hope this is what you are looking for link
So I did some research and testing of using a listview in a scrollview, and as a lot of people may know this is supposedly bad to do, since they both scroll. It also means I can't show the complete listview as it will wrap to be smaller.
I have seen places which re change the height of the listview to fix this problem but again most people say that it isn't preferred.
What I would like to know though is what is the preferred way of making a nonscrollable listview like view? Basically I want the exact same as the listview but obviously non scrolled and the height based on its contents. I would prefer to work with the layout in as much XML as possible, and I would like to be able to send my array list to it to view on screen. Unfortunately either my search skills are quite dull, as I haven't been able to find anywhere that really explains the preferred method so I thought I would ask here.
Thanks for your help.

I thought I would put this here in case it will help, first off I basically want to show an image, with a list of comments (each one has an author and a text) below it, the comments themselves are obtained from an array and can change. I want the whole page to be scrollable though so I can either view more comments or go back up to the image.
Using a RecyclerView and an adapter supporting multiple item types you could make a list which shows an image on top and several comments below it. Generally you'd have to check what item corresponds to each position - in your case on position 0 you have an image and in every other position you'd have a comment. Then in your adapter's onCreateViewHolder and onBindViewHolder you would check the item type and handle them differently.
You could take a look at this answer for a short example.
Let me know if you'd need any other details and/ or sample codes to get the idea. :)
I'm developing an Android App and I need to display some data in a scrollable Listview.
I will extract some strings from objects that I right now have stored in linked lists (until i come up with a better solution).
I want to display a view that looks almost like the contacts app. A list with a small picture to the left and a larger text to the right of the picture with a smaller text the bigger one. When I click on one of the items it should open a new activity.
How do I create the view? If I adds an object in the linked list it should appear in the list.
I have checked some sample code, but they all uses Arrayadapter and I dont understand how I am supposed to do.
Check this article about Adapters: http://www.vogella.com/articles/AndroidListView/article.html
If you want to add new objects in ListVew use:
adapter.notifyDataSetChenged();
Check the libraries in this question, you have what you need there:

I want to create a horizontal listview which contain many item, one item will contain a image. When user slide listview => the count of item will be fix when it display, example display only 3 or 4 image. How can I do that? Many thanks.
Edit:
I use this
to create a HorizontalList view, everything is ok but I don;t know how to make the Next and Previous button work! Any idea?
Instead of a horizontal ListView (which, as far as I know, isn't offered by the Android SDK) you can use a HorizontalScrollView. You can add the items like to any other kind of layout class.
It looks like what you are looking for is a Paginated Gallery. I have written one here.
Its still only a couple of days old but hopefully the included Activity code will get you off the ground.
I am new to android. I want to display the list of images using the ListView. The images which are displayed are decided at runtime according to server response. and also i want to embedd some text on this image(like match scoring chip). the number of images are not fix. Can anybody help me here?
I would read the 6 parts to this series. It will show you how to create your own custom listview rows to accomplish what you are asking for:
