I cant find a way to save the checkbox state when using a Cursor adapter. Everything else works fine but if i click on a checkbox it is repeated when it is recycled. Ive seen examples using array adapters but because of my lack of experience im finding it hard to translate it into using a cursor adapter. Could someone give me an example of how to go about it.code...

View 2 Replies View RelatedI am using a ListView in which only one item can be checked at a time.
This is my custom list_row.xml :
CODE:..........
I populate the list in onCreate() using a normal array adapter :
CODE:............
When the list is displayed, I want to have, say the 5th item, in the list as Checked. How can I go about doing this? I know CheckedTextView has a function called setChecked(), but how can I get my 5th item from the list to apply this function on it?
I'm facing problem in scrolling. I've 20-25 items in my List, if i checked first check box, scroll down, then come up, my checked status lost (becomes unchecked), in cursor adaptor. If i use base adaptor problem is resolved but major issue with base adaptor is performance, if my list goes beyond the 100 items.
View 9 Replies View RelatedThe problem is that when I filter the list the entries switch position in the list view. Take for example three entries: 'A', 'B' and 'C' where 'C' is checked beforehand (i.e. the entry at position 3 in the list). When I type a 'C' on the keyboard, only the 'C' entry is displayed (as intended). Now 'C' is not checked anymore, since the entry has moved from the checked position 3 to the unchecked position 1 in the list.This behavior leads to some not very welcome effects in the app. Is there a way to "move the selection with the filtering", i.e. bind the checked state to the entry and not to its initial position in the list? Or do I need to find a new approach?
View 1 Replies View RelatedI have TabActivity that uses 2 other ListActivities for the tabs. Both underlying ListViews are set to CHOICE_MODE_MULTIPLE. When I run the following sequence of events, I get a strange result: 1) Setup one activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 2) Reorient the screen (open the keyboard) 3) Setup the second activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 4) Switch back to the first tab
At this point, I can see in Eclipse that although (of course) each ListView is a distinct object, the internal variable used to store the checked state of items, called mCheckStates, is the SAME OBJECT REFERENCE in each of the ListViews.
Clearly this is an issue, since the two views should not share the checked state of items between them.
If I skip step #2, this does not occur
Here is a bit more detail:
After Step 1: ListView1 is object reference @1, ListView1.mCheckStates is object reference @2
After Step 2: ListView1 is object reference @3, ListView1.mCheckStates is object reference @4 (the reorientation recreates the views)
After Step 3: ListView2 is object reference @5, ListView1.mCheckStates is object reference @2 <-- note the reuse of this reference from step #1, not sure how/why
After Step 4: ListView1 is object reference @3 (unchanged), ListView1.mCheckStates is object reference @2 (changed) <-- same as ListView2.mCheckStates

My ListActivity is bound to an ArrayAdapter where I have overriden the getView() method. If I change the visibility of a widget in that method or modify the view's background color, those changes somehow get lost once that modified list item returns after being scrolled off the screen. In fact, some other view in the list is picking up the changes. How do I get the modified view to look the same when it's redisplayed after scrolling?

How to get the state of checkbox in a onListItemClick in Listactivity?
I have a class OnItemClickListener like this:

But only when I check the last item's checkbox, it go A correctly. Other items' checkbox are checked they just go B.
I have come across some very unexpected (and incredibly frustrating) functionality while trying to restore the state of a list of CheckBoxes after a screen rotation. I figured I first would try to give a textual explanation without the code, in case someone is able to determine a solution without all the gory details. If anyone needs more details I can post the code.
I have a scrolling list of complex Views that contain CheckBoxes. I have been unsuccessful in restoring the state of these check boxes after a screen rotation. I have implemented onSaveInstanceState and have successfully transfered the list of selected check boxes to the onCreate method. This is handled by passing a long[] of database ids to the Bundle.
In onCreate() I check the Bundle for the array of ids. If the array is there I use it to determine which check boxes to check when the list is being built. I have created a number of test methods and have confirmed that the check boxes are being set correctly, based on the id array. As a last check I am checking the states of all check boxes at the very end of onCreate(). Everything looks good... unless I rotate the screen.
When I rotate the screen, one of two things happens: 1) If any number of the check boxes are selected, except for the last one, all check boxes are off after a rotation. 2) If the last check box is checked before rotation, then all check boxes are checked after rotation.
Like I said, I check the state of the boxes at the very end of my onCreate(). The thing is, the state of the boxes at the end of onCreate is correct based on what I selected before the rotation. However, the state of the boxes on the screen does not reflect this.
In addition, I have implemented each check box's setOnCheckChangedListener() and I have confirmed that my check boxes' state's are being altered after my onCreate method returns.
Why would the state of my check boxes change after my onCreate method returns?
I have been trying to degub this for a couple days now. After I found that my check boxes were apparently changing somewhere outside my own code I figured it was time to ask around.
In my android app, I have a preferenceScreen with some checkboxes defined in a xml file and a class that implements "SharedPreferences.OnSharedPreferenceChangeListener". What I want to do is to select a checkbox and all the others to be selected as well. In the above listener I am able to modify the other checkboxes's state to selected, but my view remains unchanged. What should/could I do to achieve this ?
View 1 Replies View RelatedGiven a listview that shows checkboxes next to a list of people, I want to be able to get the names (in Strings for example) of the people who are checked. I have set my listview mode to allow for multiple checks.
getCheckedItemPositions()
Will get the positions but I can't figure out how to iterate over the listview to get the names. Also Eclipse tells me that getCheckItemIds is not a valid method for ListView.
I have a ListView that just contains a CheckedTextView. I have a very simple CursorAdapter that populates CheckedTextViews. When I click on an item, I can see that I am responding to the correct row, store the value in my model and the CheckedText gets checked. However, when I scroll down and then back up again, while I see that the model contains the correct value (in #bindView), calling #setChecked on the CheckedTextView has no effect. Ie All items are unchecked. Code...

View 1 Replies View RelatedI am having a really difficult time trying to work with android's ListView multipleChoice mode. Here is what I am trying to do:
I have a "players" button in a game setup screen. When this is clicked it opens another activity with a multipleChoice ListView of all the players in the database in CheckedTextViews. I have this working properly and when you click on a player they will be added or removed from the game via a query to the game_players table.
The problem I am having is in setting up the ListView so that the players that have already been added to the game get checked initially when the activity opens.
I have tried to do this by iterating over the entire list in the ListView activity but this doesn't work because the Views that are not currently visible can't be accessed to check.
So now I'm trying to do this in my extended SimpleCursorAdapter in bindView but I can't even get this simple code to work:
CODE:.........
It correctly sets the player's name with setText(), but I can't get any of the boxes to check in bindView. Is there somewhere else I should be doing this or am I just doing it incorrectly?
Where do I find the file that has saved spell checked words I added to the dictionary. Sometimes I misspell words and it auto saves them...I want to delete the incorrect ones.

View 1 Replies View RelatedI kind of have a 2 part question here.
1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?
2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.
