I have some data in my data base and i want to display it in android phone.I want to display my data on Grid-view because there is continuous variation in my data therefore i want to display in android like asp.net gridivew.Please anyone help me to do this or any example code to do this
You need to have two things for the Gridview:
Use Gridview component in a layout.
Inflate the elements in a getView method and set elements position by position to the Gridview items.
You can follow this link to understand it:
http://android-coding.blogspot.in/2011/09/simple-gridview-example.html
You are on the right track as you have decided yo use a dynamic view for your varying data. You can use any one of the dynamic view(list view, grid view, gallery, etc) depending on the kind of data you need to display.
If you are not familiar with these dynamic views then you should first go through some tutorials on implementation of these views. First try with a basic program for understanding the concepts. Once you are clear with the concepts then all you need to do is to replace the underneath data with the data fetched from the data base.
There are lots of tutorial available on net. Here are some links:
GridView tutorial
ListView tutorial
Feel free to discuss in case there is any doubt.

I want to fetch data from web api and fill in ListView in android. I have already learnt how to call web api and successfully done in my app, but the problem is how to show in my ListView? I want to fill data as in shown in below image.
.
How can I fill as exactly as in image? Which components are used in ListView? If this is not a ListView then which layout is this? I also want to know how can I use above buttons(Overview, matches, Teams, standings ). I want to change the data when I press different buttons. Please share your experiences and suggest me some learning sources.
create a custom java class describing a single Item as an object that will contains a number of variables for storing data that will come from web API.
create a custom layout (list_item.xml) contains two ImageViews and 3 textviews .
store your API data in an Arraylist of type (YourCustomJavaObjectclass).
create a custom Arrayadapter , then inflate the (list_item.xml) inside the getView method and then bind your views with data from the ArrayList.
For more info read this article
https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView
For creating these (Overview, matches, Teams, standings) you have to use ViewPager and FragmentPagerAdapter , for more Read this https://github.com/codepath/android_guides/wiki/ViewPager-with-FragmentPagerAdapter
I'm using a RecyclerView to display a list of data from server. The data contain text and an uncertain number of urls of images with HTML tag. For each item, I'm now using HTML.fromHTML() with a ImageGetter to parse the data, get images and display them in a TextView. However, the images in TextView cannot interact with user. Events on the images like click, magnifying and save are not supported by TextView. And I tried using a Webview instead, but its performance is poor.
I also tried to write a compound view which extends a LinearLayout, and add TextViews and ImageViews dynamically (the number of images for each item are not certain), but it behaved strangely in the RecyclerView.
Is there any better idea or should I improve my solutions forementioned?
Thanks in advance!
The solution has been found by myself with the help of other programmers on StackOverFlow. For those who may see this question, please check Android - Custom dynamically-generated compound View recreated in RecyclerView, causing poor performance.
The idea is simple, creating a CompoundView extending LinearLayout which adds TextViews and ImageViews dynamically based on the data attached. Note that the processes of creating views and setting data for the them are seperate. For other details, please check the url above.
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:
Lazy load of images in ListView
Good Morning All,
I am creating an application to display List of applications with their data usage.
I want my list to look similar to Traffic Counter Pro on android Market
I have also added the print-screen on my box.net as SOF does allow me to upload image
So Can someone direct me how to create ListView like this?
My second Question related to this how to create a tab style Activity.
Two examples that helped me a lot:
http://www.codemobiles.com/forum/viewtopic.php?t=876
and
http://android-developers.blogspot.com/2009/02/android-layout-tricks-1.html
i hope they are usefull to you.
You have to use custom ListView to embed images and format texts as given in the listview.
check out this example or this example or this example or even this example that gives you good understanding on listviews.
Good luck.
This is ListView which items consist of 4 Views objects, look through the tutorial of how to create ListViews and through the tutorial of how to create TabActivitys. And also use links suggested by #parag.
If you observe the screen shot carefully you can identify that group of these fields are available as list item.
They are
Application Icon
Application Name
Data Uploaded
Data Downloaded
Total Data Usage
So you have to create a layout with these fields as children with appropriate position and Use this custom layout as child layout for ListView.
I hope it may help you.
I've been trying to find a tutorial of how to create a ListView that get its data from a server dynamically as it's scrolled. I have not been able to find complete documents of how to do this. Only small examples or ListView tutorials that deals with set arrays. This has left me where I don't know where to start building the ListView code.
I have some code that gets data from the server. I also do have all the layouts and basic Activity code.
How/what do ListView do to get one more rows as it is scrolled?
And when I need to have different row layouts. How do ListView handles this?
Is there a complete tutorial that deals with ListView and getting data from a server?
How/what do ListView do to get one more rows as it is scrolled?
There is nothing built into Android for this. You could use my EndlessAdapter, either directly or as an idea of how to accomplish similar ends in your own code.
And when I need to have different row layouts. How do ListView handles this?
You need to implement an appropriate ListAdapter, one that has proper implementations of getViewTypeCount() and getItemViewType().

Along with your other two bullets? Probably not. Your requirements are individually uncommon and are even less common in conjunction.
