I have a list view with 2 buttons on each row. I am using a cursoradpater to populate the list. I am also using the view holder pattern on newview() bindview().
My questions are: where do i put the clicklisteners for the buttons knowing that the action for the button is different from the action of the list item itself? Do i keep the onListItemClick ?
I have a CursorAdapter attached to a ListView, the ListView contains checkboxes for every row. When I check/uncheck a checkbox in a row it will update it to a 0 or 1 in the database (This is working fine) I also have another checkbox in the same Activity that when pressed will disable all the checkboxes in the ListView [ setEnabled(false) ].
The problem is that when I press this checkbox the ListView checkboxes return to their initial state when I started the activity. It does not matter the number of checkboxes I changed during the activity.
However, if I press the back button and then re-enter the activity all modifications are saved because the Cursor is refreshed. I am calling notifyDataSetChanged() at the end of the the methods that disables all the checkboxes.
I also tried this for every checkbox in the ListView but it did not work (was unable to check a checkbox) Any ideas?
I have a ListView backed by a custom adapter based on a CursorAdapter.The cursor I give it is based on a list of Notes in the database (each note is a DB row).Everything works just fine until I delete a note from the database. I'm not sure how to properly update the cursor/adapter/listview to display the new data.I've read conflicting posts on using adapter.notifyDataSetChanged() vs cursor.requery() to refresh the UI, but neither of them seems to work in this case.The only way I've been able to refresh it is by creating a new cursor from a new query and calling adapter.changeCursor(newCursor).Could someone demonstrate the proper way to update the backing data and then the UI (with psuedocode if possible).
View 2 Replies View RelatedI'm watching this video http://www.youtube.com/watch?v=N6YdwzAvwOA and Romain Guy is showing how to make more efficient UI adapter code using the getView() method. Does this apply to CursorAdapters as well? I'm currently using bindView() and newView() for my custom cursor adapters. Should I be using getView instead?

I have a LinearLayout layout with a ListView in it. I've made the android:background of the LinearLayout (I've also tried it on the ListView) be an image that I would like for my background.
This works fine enough. However, when I start scrolling through the ListView, the background often disappears and becomes black. If I move it around some more I may be able to get it to appear again. It would seem that Android is drawing over, or perhaps painting what's behind my background onto the items.
Threre is a unique resquirement for my project.
I need to create a custom scrollbar for a listview.

I am having trouble getting my layout to give me result I need, I already tried many options and it seems that I'm doing something wrong or completely missing something.
I have a listview with a custom row layout I can't seem to working although it shouldn't be complex. I need of the list row to insist of:
Icon -- title text (bigger and bold) with a short multi line text under the title -- ImageButton
My problem in most of my tests is the icon to the right usually doesn't appear, I guess my center group grows and takes all the space of the button. My last failed attempt was with a Relative Layout, didn't have too much luck with a Linear Layout either.
Here is the row XML:

I am running a sqlite query and binding the returned data to a ListAdapter.
I have used the following example
ListActivity | Android Developers
However, having defined a seperate layout for the rows I cannot change the typeface for textview text1 to a custom one from assets
Here is the row layout
CODE:................
Here is the code from the andriod tutorial
CODE:............
We'll define a custom screen layout here (the one shown above), but typically, you could just use the standard ListActivity layout. setContentView(R.layout.custom_list_activity_view) ;
Query for all people contacts using the Contacts.People convenience class. Put a managed wrapper around the retrieved cursor so we don't have to worry about requerying or closing it as the activity changes state.
CODE:................
Now create a new list adapter bound to the cursor. SimpleListAdapter is designed for binding to a Cursor.
CODE:................
Specify the row template to use (here, two columns bound to the two retrieved cursor rows). mCursor, // Pass in the cursor to bind tonew String[]{People.NAME, People.COMPANY}, // Array of cursor columns to bind to. new int[] {android.R.id.text1, android.R.id.text2}); // Parallel array of which template objects to bind to those columns.

I have an ExpandableListView that I want to populate with my custom views of type NoteView. NoteView extends LinearLayout and contains two buttons and a checkbox. I have almost everything working, the NoteView's are being populated with backing data, the lists are getting filled, and the buttons are clickable and perform the required tasks.
The problem is the ExpandableListView no longer responds to click/longclick/keypress events at all (other than selecting list items with trackball/DPAD).
I replaced my custom view with a standard TextView and the touch events flowed normally again, so it is almost certainly something I am doing wrong with my custom view or some obscure ListView setting I am overlooking.
Here is my NoteView code and XML Layout. What am I missing?

I want 2 things:
When i move with arrow keys, the item selected changed its background. It's works fine with the actual implementation of selector.
When i press a item, the item changed its background too, but it doesn't work with the actual selector.
I try to set also into the ListView android:listSelector="@drawable/list_selector" but it doesn't work neither.
