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...
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.
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 am using a ListView in which only one item can be checked at a time.
This is my custom list_row.xml :
I populate the list in onCreate() using a normal array adapter :
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?
Ive got ListActivity and i am using custom CursorAdapter. in each item of the list ive got also checkbox. now i have in my list screen a perm button, when you press on it, it should find all the checkboxes which are 'checked' and do some operations on the item which it's checkbox is 'checked'. how can i retrive all the checked ones? ive done focusable:false, so i can use OnClickListener, but i dont know how farther then this..
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?
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'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.
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:
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
I have a ListView and an ExpandableListView inside of a TabActivity. I have overridden the setOnItemClickListener for the ListView. I have 2 tabs and one uses the ListView and the other uses the ExpandableListView. For some reason I cannot click on any of the items in the first ListView. If I change tabs to the ExpandableListView and then go back to the first tab it will then allow me to click on the items as usual. Any ideas on why this is happening. Is there some kind of weird focus thing going on? Code...
I have an Activity which contains a ListView defined in XML (its not subclassing the List Activity class).I want to display a message when the ListView is empty, so I tried doing so with the setEmptyView method: Code...
I have a ListView that is being populated. I have checked the contents of the datasource and it contains valid data. Unfortunately, the number of rows is correct, but the text I want to display is not appearing. Here is how I am setting up the ListView: Code...
I am creating lists in my android app and would like to capture the text of the list item that is clicked but I want to do it in a seperate function so I only have to write the code once. And I want to be able to compare the string to another sting.
I am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date? Code...
In my listview i'm adding more than 2500 items. When i try to use text filter option it is taking more time to filter. I asked this question in android groups already.But i can't get the answer what i expected.
I have a ListView that get data properly and they are added to my own ListView using a ArrayAdapter class and my own ArrayList class. When I for example, typing in "table" I want it to sort from the loaded titles in my ListView and than it should show me the items that are left and matching table.
I always get an ClassCastException error... i do not what else to do... - I'm using a data biding concept to populated the listview from a sqlite3 database. - I just want to get the selected item text after a long press click.
This is the code of the activity:
This is the xml where a define the rows to show on the listview:
I have a layout with a ListView that contains EditText objects that can requestFocus() when the user chooses to edit the list item. I make sure to call setSelection() on the ListView when this happens, and then have the EditText request focus and then use InputMethodManager.showSoftInput to show the soft keyboard. However, when this happens, the list view is being resized correctly, but the selected list item remains below the fold and the user has to scroll up. This is working properly on 2.2, but is failing on 2.1. Any ideas for making sure the list selection remains visible?
I am having problems figuring out how to access text settings for an item in a ListView. I setup a basic ListView in my layout: xml:<ListViewandroid:id="@android:id/list"android:textColor="#ff000000" android:layout_width="wrap_content" android:layout_height="wrap_content"android:layout_x="1px" android:layout_y="161px"android:visibility="visible"></ListView>My ListAdapter is a SimpleAdapter with a hashmap of values displayed in my ListView.
I have an onListItemClick method in my ListActivity which captures and properly identifies the item selected in my ListView. What I am trying to do is change the text color or font of the item that is selected in the method, onListItemClick(ListView l, View v, int position, long id). Is there a way to access and change the text font and color using the ListView or View object from this method? I traversed the methods of each class and can't seem to find one that allows for that functionality.
I populate ListView Using ArrayAdapter, constraint: each item Text in ListView represting some actions, and each action (Item text in ListView) represent its individual color. problem: i cant change the color of each item text in ListView, according to supplied color formula. using ListView thanks i am waiting ur reply?
I have a ListView that is backed by a SimpleCursorAdapter. I'd like to be able to filter the list like you would a contacts list, just by typing, and I came across the textFilterEnabled() Problem is, I couldn't see how to get it to work with a SimpleCursorAdapter. Is this even possible?
