I am making an app which required my checkboxes to be checked at once
when i check the main checkbox.
I am using one normal checkbox widget which i am hoping will work as
my main checkbox and i am also using LIST of multiple
choice(simple_list_item_multiple_choice). Now i want to check all
these listview's checkbox when i check my main checkbox.
I am stuck at this part :( please help!!!!
Thanks,

Correct way to check all checkboxes in ListView?

I'm new to both Java and Android development and am wondering how I would go about using a listener to detect when a check box is checked/unchecked. I understand how to do this if the check box was by itself however how would I do it if the checkbox is inside of a list view?
Hopefully this is not too vague.
Thanks
I guess you are using a custom xml for the listview item. In that case, you have to also create a custom Adapter for the listview, and add the listener to the checkboxes there.
here i used the listview with radio button and checkbox , i want my radiobutton to get checked only when the corresponding checkbox is selected and even i want those checked references so that i can put some conditions according to my requirement, thanks in advance.
Is there any better way than using listview ?

Yes.
CheckBoxes are used when you want the user to select more than one option.
RadioButtons are used when you want the user to select one option out of many.
With that being said. You could either only use CheckBoxes or RadioButtons, using both together doesn't make sense, because both server a different purpose.
You could however use a RadioGroup instead of a ListView.
I've been trying many things with list items and i'm facing some problems. In my previous question, thanks to #nEx.Software i was able to resolve the problem. But I'm still missing some concepts here.
Right now i'm trying to differentiate between an item's click and a checkbox within it. However, I want to do it without extending the array adapter. Is there a way to use both methods: listView.onItemClickListener() AND listView.getCheckedItemPositions(), together!
There should be a way to use an xml file [doesn't matter how complex it gets] along with extending the available Views and this thing should be done.
Putting it simple, open the gmail app, and u'll find all emails listed with checkboxes where u can click on the checkbox to mark it OR the rest of the item to open the email.
Again, I know that it is doable with extending Adapters and adding an Array for the checkboxes, but, is it possible to use the convenient methods: listView.onItemClickListener() AND listView.getCheckedItemPositions()? is CheckedTextView a part of the solution?
One more thing, rather than just answering me [where i become lazy]
Wheather it is possible or not, is there a verry reliable reference for such issues? I would really like to fully understand everything that goes into this matter... if its not possible, i must be able to tell why!
Thank you :)
add custom row into your listview. into your custom row you add one textview and checkbox into linerlayout and get linerlayout click event.
In my game application am using a listview to select levels. Am activating this listview item onclickable if the previous level is cleared. I need to differentiate the activated and unactivated level's in listview.How can i make it possible? If possible suggest me tutorial. Thank you
you can put your logic for activated and unactivated levels in getView method ,check if activated then inflated activated row otherwisw unactivated row.
First check this and this stackoverflow questions and try some code and post your question if you have any problems. Please try first.
You can use setClickable(false) to disable touch events on list. To make it look disabled, you can change the textView colors in the list items and get such effects.
Thanks
Friends I need to check only one check-box at a time among more than one check-box.Can any one have the code and idea please.
Instead of CheckBoxes you should use RadioButtons in a RadioGroup.
Putting the RadioButtons in a RadioGroup ensures that only one of them will ever be selected.
If you don't like the way they look, you can customize them, like you can with any other layout element.
assign id's to your Checkbox and select any checkbox and retreive its id
android.R.layout.simple_list_item_single_choice use android 's default layout may help u.
For Single Item checked at a time then you have to simply use :-
android.R.layout.simple_list_item_single_choice
For Multiple Checkbox at a time then you can use this :-
android.R.layout.simple_list_item_single_choice
