I have a question, if I want to load a ListView directly from a database, for example on the first screen I'll have a search button that will search the database and display the results in another screen in a ListView. How would I do that?
CursorAdapter or SimpleCursorAdapter will help you.
Your question has a few parts, if you don't already know how to start.
1) First you will need to learn how to set up a custom ListView and a generic adapter
http://www.vogella.com/articles/AndroidListView/article.html
2) Then you need to figure out how to source your adapter with data pulled from your database

I have a very simple question. I'm working on an Android application where I make use of Simple Adapter for ListView. Now I need to append items to this ListView dynamically. I know it is possible to do so in case of Array Adapters.
It is done as follows:
adapter.notifyDataSetChanged();
Is there any equivalent for the same in case of Simple Adapters? I couldn't find much relevant links regarding this on the net.
Kindly help.
Thanks in advance!
I think not, but you always can create a new SimpleAdapter and call setAdapter again with the new adapter.
If you are going to add/remove elements you, probably, need some other adapter not a SimpleAdapter. Because they say in the docs that SimpleAdapter is 'An easy adapter to map static data to views defined in an XML file'
I have a listview that displays player names from a datastore class and i would like it to also display an images of the player. how can i change my listview to display images aswell?
This is my code to populate the listview:
player_List = (ListView)findViewById(R.id.listplayer);
player_List.setAdapter(new ArrayAdapter<Player>(this, android.R.layout.simple_list_item_1, dataStore.getPlayers()));
any help will greatly be appreciated!
By the way i tried a simple array adapter but that only seems to like string objects! and i want to put a player object!
Thanks

I'm Developing an Application. I'm displaying Thumbnail Image and Corresponding data with the image in ListView the data and images both are downloaded and parsed through XML parsing For Displaying images I used this tutorial
Lazy load of images in ListView
But I'm not getting how to display the parsed data in ListView.
Thank you
Abhishek
This is what u should do..
After parsing the data create objects for each row in listview(i.e,use a Custom Class)
Iterate through all the objects
Add to listView Adapter
Use listview.notifyDataChanged() function everytime.
This should do the trick..;)
By using the BaseAdapter, its possible.Inflate a layout that have textviewand Image view in
Listview row.
Please look in below link for the tutorial. i am sure you will get to resolve you problem on your own

I know my question isn't formulated well.
I'm adding items to an ArrayList downloaded from JSON file and the ArrayList is passed to a ListView.
So what is my problem?
After displaying the data from the ArrayList i wan't to add new items to it so they can be show right after they are added. I managed to do this by setting the Adapter for the ListView again after the data is added.
Displaying the new items should look smooth but instead it looks very sluggish and i know it's not the right way to do this.
I've searched about this problem but couldn't manage to find anything, so for anyone answering
Thanks in advance.
Its very easy
You need not to set the data adapter again to the listview..
instead
call after you downloaded the new data
listView.getAdapter().notifyDataSetChanged();
this function will tell the view to be build again.
In addition Check the following link. here i mentioned a complete code to use listview properly.
Using this we can achieve any listview behavior. We can embed animation also.
Change ListView background - strange behaviour
Hope this help :)
