ANDROID: MULTIPLE SELECTION LISTVIEW
I have a app that displays data in a listview using baseadapter. The user is able to click a element in the listview and it takes the user to a page where they can edit the data that is being displayed on that element. When the user clicks back it takes the user to the listview however the changes are not updated. How can i update the listview once the user clicks back.
I think just set your adapter in onResume() method, so each and everytime you should go to on that screen, each and everytime it will refresh your Adapter.
I would like to open a listview by clicking on list items, which means when I need to show some categories in a list view and if I want that when I click on any of those categories then another listview should open with subcategories. And the same with working with subcategories, that when I click on subcategories then another listview should open with related sub-subcategories and viceversa.
Please tell me how can i do the above if i want same listview for all operations?
Thanks!

I have created a custom ListView.. every element of my ListView constructing from a layout.
My layout will have some TextViews and a ToggleButton. My ListView will have some 50 elemnts and my device screen can show 2 elements at a time.
Now if we select ToggleButton on a Item and scroll down my ListView , the selected item will be out of screen and when I come back to the previous selected item I am observinf that selection for that toggle button is gone.
I know that this is a normal behavior in android that It will construct the elements which is currently displaying.
But I want to keep that value.. Is there any way that we preserve selection. or can I tell ListView to donot construct every time.. memory is a not a issue for my application.
Please let me know if there's any good solution for this.
You could store the states of the checkbox in a map with the position as the key. So whenever the list reloads after scroll, it loads based on the hashmap state. You should write this logic in the getView()
