Android :: Check A Particular Item In A Checked ListView?
Oct 11, 2010
I 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?

The 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?

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.

Given 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...

Currently I have a list view within it each row has a checkbox attached. I would like that once any checkbox is checked, at the bottom of the screen a view displays, and once none of the checkboxes are checked, the view automatically disappeared. Possible to do this?

I 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?

I 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

In my application has a ListView. When long press on item the "Context Menu" will appear. I want to check the data ID, then set disable/enable to my Context Menu "Items". I can not find out the function like getMenuInfo() or something like this.
@Override
public void onCreateContextMenu(ContextMenu menu , View v, ContextMenuInfo menuInfo)
{ super.onCreateContextMenu(menu, v, menuInfo);
menu.add(0, ADD_FAVORITE_ID, 0, "Check");
menu.add(0, ADD_FAVORITE_ID, 0, "UnCheck").setEnabled(false);}

I was curious if there was a way that I can assign each menu item in a ListView its ID from the SQLite database, so that when I do something like onClick, or using a ContextMenu, I can tell what item / row I am referencing to.

I have an issues, I want to show 20 items in the list.
But there is a catch: if the user scrolls down to the bottom of the list, there will be an item that says: "Show more items", and when the users click on it, more items will be added to the list.
My question is how is poosible to have a last item, that has a different style and looks different: and does different things,(I think this is used in QuickSearchbox)

As I mentioned in the email subject, I want to select an item (e.g. Department of Human Resource Management) in my ListView. And you can see that: I had try to use setClickable(true), setChoiceMode(ListView.CHOICE_MODE_SINGLE), setFocusable(true), setFocusableInTouchMode(true), no matter I use touch screen to click on the item or use the scroll ball on my mouse to select the item, it also doesn't work. Is there any mistakes in my coding? I hope someone can give me some ideas what I should do. because I am a beginner for developing Android application.
And the following is my coding: package com.example.abc;.............
