i'm having a problem (newbie one) with a CheckBox Listener AND a ListView. I need to request the '...long id) that passes through the Overriden method onListItemClick and put it into a OnCheckedChangeListener. How should i do that?

I need your help. I'm really new to Android, developing in Eclipse with the latest 2.1 SDK. This is really simple. I make a ListView which is filled with Checkbox widgets. My code:..............
View 2 Replies View RelatedI have a listview with some checkboxes. I want some of them to be prechecked when the activity starts. I have the positions of those checkboxes which needs to be pre selected.
View 2 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 am facing a very mysterious Problem. I am using a ListView with CheckBoxes that can be clicked to select people. The row layout is the following:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <CheckBox android:focusable="false" android:onClick="onSelectPerson" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_marginRight="5dip" android:layout_marginLeft="5dip"/> <TextView android:id="@+id/person_name" android:text="test" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:textSize="18dip" android:layout_marginLeft="5dip"/> </LinearLayout>
As long as the amount of rows doesen't exceed the screen size (-> no scrolling) everything works just fine. But as soon as I have more rows then the screen size (-> some rows are hidden and have to be scrolled to). I have a very mysterious phenomenon: If I check the top row and scroll down some of the previously hidden rows are randomly checked too. If I scroll up again, again some of the before hidden rows are randomly vhecked (the CheckBox I clicked in first place may or may not still be checked). Also the registered onSelectPerson callback is only called for the CheckBoxes I really click. The other CheckBoxes just change their state to "checked" without calling the callback method. I have the same phenomenom on the Archos IT 5 and the Nexus One. This must have something to do with the ListView implementation but I can't quite figure out what the problem is.
I am building a list and the list contain for every contact a checkbox to chose which one to modify for example, the problem is that when the list became longer than the phone screen and the scrolling is active; when i select a check box , a second one is automatically selected in the bottom of the list.the problem is the automatic selection of the second checkbox; please let me know how can i fix it? below is the code i am using for getView method.

I have being playing around with expandable list views recently. I am trying to get a list view that has a checkbox as one of the elements of the child view.
I found this tutorial, http://mylifewithandroid.blogspot.com/2010/02/expandable-lists-and-check-boxes.html, and it seemed perfect. However when I compiled it and started playing with it I realised its very buggy. Checking a box in one group can cause a random box from another group to check or uncheck.,
This is the only tutorial I can find on this, It seems like a thing that would be used in a lot of apps, so I was wondering, is there any other good tutorial or resource out there that deals with this? Or even better, would anyone care to show their own code having gotten this to work...
I have a ListView, and within each list item I have some TextViews and a CheckBox. When I check a CheckBox and my onCheckedChangeListener fires, everything works as it should. However, random other checkboxes get checked once one is checked. Here is an example.
If I click on the first CheckBox:
8 is checked.
15 is checked.
21 is checked.
27 is checked.
33 is checked.
41 is checked.
Then if I scroll all the way up, none are checked until 6. The next being 13.
I want to add some checkboxes to a LinearLayout at runtime. The orientation is vertical and I want the checkboxes to appear at the bottom. I create each checkbox like this: CheckBox box = new CheckBox(this);
Then I add the box to the current view like this: addContentView( box , params ); What should be the params to get the effect I want? So far, everything I've tried ends up overlaying the new checkboxes on top of each other and on top of the other items in the layout. I want everything stacked in a column with the new checkboxes at the bottom.
i'm using the default way to call the contact picker.
public void showContactPicker(View view)
{
Intent newIntent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
startActivityForResult(newIntent, 1);
}
but i need to select multiple contacts using checkboxes. how can i put checkboxes in the contacts list? is there a method that i can override that can add checkboxes and get the selected contact ids?
I have report which consists of 5 questions (there can be only one answer or multiple choice answer). Question are different for each report. So everytime I generate questions and answers as RadioButtons (one answer) or CheckBoxes (multiple choice answer)...But now I really don't know how to save those answers (I'd like to save to it as _question_id, _answer_id). How can I assign good _answer_id, to _question_id...
View 2 Replies View RelatedI'd like to have a dialog box which prompts the user to select from various checkboxes, then confirm "Ok" or "Cancel". I have this working, but my only issue is the dialog always retains the previous checkbox selection state from the last time the dialog was shown. I'd like to always force the checkboxes to be unchecked (false) every time. Is there a way to accomplish this?............
View 4 Replies View RelatedWhat should I do to use custom checkboxes if I add my checkboxes dynamically in my code? (On the java code not on the XML files.) I'm following this tutorial, but using it I can't achieve my goal. For example, I have a tableLayout and I want to add a checkbox for each new row I have.

View 1 Replies View RelatedIn my apps preferences screen, i want to pop up a dialog that shows a list of checkbox items that are dynamically generated.
How does one do that and also, how does one get the checked values? I have made custom dialogs in the past, but for some reason my brain wont function today ..
I have some 34 checkboxes on one Activity which i have to mark and unmark. and I want to save the status of the each checkbox.
I want this persistently. So should i have a sqlite table or preferences ?
If sqlite table is recommended, then what should be the ideal table structure design?
This application is called "Get Healthy". I have no clue of how to activate the checkboxes. There are four diffrent checkboxes listed and with every diffrent combination there is a diffrent calculation. For example, Calculating a User's Daily Caloric Intake
The daily caloric intake is the amount of calories that someone is consuming in order to maintain their current weight. This calculation takes the following characteristics into consideration:
male (checkbox) or female (checkbox)
active(checkbox) or inactive (checkbox)
I want to make a dynamic layout which contains mixed elements
[text] [checkbox] [button]
[text] [checkbox] [button]
[text] [checkbox] [button]
I would like to change text and back ground color of my Listview without building custom rows. Is this possible ?

I have a listview within an activity and at the bottom of the screen I have a scrollable gallery, my problem is making the listview clickable, I would normally use the listview position by doing if(position == 3) and then create the intent but postion is being used by my gallery. I listview is in the main.xml populated by an array.xml, can I add an id i.e android:id in the arrays.xml and create an intent with that, or can I create a listactivity and still use position to fire an intent if so how would I do this.

i want to implement listview with uses different xml layouts for rows depending on underlying item. A non optimal solution will be int getView method just to inflate every time a new view depending on the item from the adapter. Is there a better way to do this?
View 2 Replies View Relatedis it possible to let my ListView show 2 different rows? On the picture you can see at the top something like a "teaser", the other rows are normal ListView. The screenshot is from the iPod. With their framework it is possible to show 2 different row styles. I badly need this on Android... Otherwise I would use a tabel design. But adding rows dynamically would be such an overhead instead of using ListView SimpleAdapter addItem...
View 2 Replies View RelatedIs there a way to do groups in a listview? Like I have a list of certain states, each state has its own sublist.

Is there a way to do this built in or would I have to do something tricky with a custom view for Parent elements then switch the view back to the child element style.
