Is it possible to load radiobuttons/radiogroup straight from a sqlite table? That is, the code to generate a radiobutton/radiogroup is loaded from a sqlite column.
I'm attempting to load this information from the database table directly into a ListView. So a user can scroll through a list view and click radio buttons inside each ListView
for that you can create custom listview and in to that handle it's onclick for appropriate outcome.

I have created a list view and displaying the data from SQLite in the list view.
I need to delete, edit the specific row from the list view as well as the database table which the user pressed in the list view.
is there a way or any tutorial that explains a solution to this problem?
or else, I would like to know a way to display data from sqlite database along with editing deleting etc.
I am trying to create a VanSale model app in android. I have a form with customer name and customers item field. In the item field I have created a custom listview with 7 columns.Column contains Sl No, ItemCode, ItemName, Quantity,Discount,Rate and Amount. 5 items will shown in the list. When I pressed a add button will add 5 more items to listview. List items can be upto 100. I want to insert the each items in the listview into sqlite database. How can I done this? Is there any other easy methods to done this?
First Think, you have to learn about looping, iteration conceptual in your mind and take a practice using simply array or list data. if You already know about the sqlite database and listview, i thought you only need to made some function to get from listview using position, and another function to write into database.
Second, Listview has position parameter if you passing it into onSelectedItem method, or you can get directly from listview self and get using position, and sqlite db which you use list or array has position also.
I think its a logical question. so my answer is logical too, or you can attach your code's also here to detailing your problem, good luck.
i have this table with dynamical table-row adding.
What I would like to do is not load the whole table because it sometimes has more than 10.000 rows.
I want to make a dynamically load the table is that possible?
For such thing, you must use ListView instead of TableLayout. Because with ListView, you can implement onScrollListener, with which you can load more iteam as and when required.
list view does have on scroll listener that will listen if you change focus of list view and you use simple logic to find when list view end is reached and respond accordingly
I'm trying to develop a 3 column gridview and I need advices.
2 columns data coming from database and 3rd column is a delete button.
Data is stored in sqlite and columns like following;
1-Name: name of the product(string)
2-Type(Picture): type picture of the product, there are 10 pictures(type1.gif,type2.gif,...type10.gif)
3-Delete: It is a button or imagebutton which will delete the data from sqlite db.
Can you give a sample project link or tell me which one is better for performance and less code, gridview or listview?
As a suggestion,
you can create a list view, there you need to create a custom layout for the each row. This custom layout consist with textview (product name) , imageview (for the image) and a button. Once you click a certain button , you can get the product name/id from the respective model and delete the corresponding row from the database.
Use view holder patterns for this, and use lazy loader or similar technique to load the rows into the list (if total rows count is much larger).
This would be a the one of easy/efficient way to do this and you can easily find the code from google.
I need to create an activity(view) that shows several lists, for example:
(text)Fruits:
(item)apple
(item)orange
(item)pear
(text)Veges:
(item)Cabbage
(item)Carrot
all data are read from a database, so I cannot determine them and create layout file(xml) for them, what's is the best way to create this? Also, list items are clickable which directs users to another screen.
Thanks!
ListViews are filled with data using Adapters. So, you can use a single layout with a ListView and change adapters depending on what you want to display.
Have a look at Adapter interface.
And if you want to have several ListViews, then in your case I'd use a single ExpandableListView widget with differet groups like Fruits, Veges and so on.
If you have created a database using sqlite already, U can use cursor adapter to fetch the data from your database. Its really simple. try to find out how to fetch data from database and how to insert values into listview using cursor adapter.
