I have a list with checkboxes, what I need to know, is there anyway that when i click on the checkbox ONLY it will be checked and when i click on the list item i want to trigger a function but not to select the checkbox.
in other words, If I tap on any row , the check box should NOT be check unless I click on it directly.
here is my list:
listView.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice , items));
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
I implemented this a while back, the thing to do is to use multiple layouts, one containing checkbox, another containing the text of the list item, and wrap it a relative layout, and add this as a row for each list item, i.e. use it to populate and create your row dynamically.
Now set an onClickListener for this list and within that block of code listen for identity of which view is getting the click and do different things.
^basically what the other commenter said. I personally think the easiest thing to do would first be get your layout perfect for a single list item, then make a scrollview, put a linearlayout in the scrollview, and populate the linearlayout with the individual list items using a loop. Set onClickListeners and such in the loop, or use a single onClickListener with different tags or ids for the list items...

I am new to the Android Development. And I am stuck with the Customized list view.
Actually, in my activity there is two customized list view say list1 and list2.
Each list view's row having CheckBox, TextView and Delete button.
Now, my problem is that if in list1, for any row if the check box button is checked then at that time I also have to checked the checkbox of list2's child also.
I don't understand how to access the list2's child into the list1.
Please help me.
Thanks in Advance...:)
Use the function setOnItemClickListener of list1. You can get the position of the value you have selected. Take that position and use it to select the value in list2
I have problem in list view with single choice mode. I want to display three text views with one radio button in list view. list view working properly. The problem is single choice mode. i want to select only one list item at a time rest of thing unselect mode. I searched last three days still i won't get any idea. Could you please help me. Thanks in advance.
You could make a variable that saves the radiobutton chosen.
In each radiobuttons onclick you could set the variable value and set the rest of the radiobuttons to unchecked.
Hints:
in the radiobutton xml add: android:onClick"method name"
In the method add View view as an argument (example: public void clickMethod(View view).....)
Im not sure if you can display 3 textviews and a radioButton without customize ArrayAdapter
but if you have succeeded to build the list you can do the following
1- remove the focus from the child elements(radioButton and textviews)
you can do this from the xml [android:focusable="false"] and for the listview [listview.setItemsCanFocus(false)]
2- make the radioButton not clickable from xml[android:clickable="false"]
3- create a variable to hold the clicked item (in the custom adapter) and make public method to update this position
4- create OnItemClickListener for the listview, update the clicked position in the adapter
and call adapter.notifydatasetchanged
5- be sure to in getView method to make the radioButton unchecked and make the view at that position is checked
Without using listactivity, in a simple activity how can I have checkbox at the left followed by the text in the right for every row of a listview. If I tap on any row , the check box should be selected.
Just get reference from xml, using:
listView=(ListView)findViewById(R.id.listView);
Set adapter on your activity
ArrayAdapter<String> adapter=new ArrayAdapter<String>(this, android.R.layout.simple_list_item_multiple_choice, arr);
listView.setAdapter(adapter);
setChoice Mode to single choice mode or multiple choice mode
listVIew.setChoiceMode(ListView.Choice_Mode_Mutlitple);
now you can select and deselect checkboxes in listview.
Check out this tutorial - it will give you an idea how to implement custom listview item layouts.
http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters/
To make the checkbox change state when any part of the whole item is clicked, add an OnClickListener to your item's layout root element (convertView) and switch the checkbox state there.
PS Don't mind the ListActivity stuff there. It will work either way. What matters is the custom Adapter and it's getView() method that inflates custom layouts of your items.
UPD Here's a more adequate way to accomplish what you want: your items should implement Checkable and then you can use ListViews singleChoice or multipleChoice mode with it. Here's an answered question about that, although, the answer seems to miss the actual part about the checkbox. But I bet you can figure it out, what matters is the idea:
Android ListView with RadioButton/CheckBox in singleChoice mode and a custom row layout
I have created one list view.. it is having 5 items...
Now I want split the list items...
when user clickon the first listitem or focus on first item then immediately it has to show followed some text views or other things..but it has to show same list..
and agian same when he clickon or focus on the second item that first item has to be close and second item has to act some thing....
I think you need to implement the concept of "Expandable Listview", so that the clicking on one item, it will be expanded with their sub-items.
Refer the android-sdk page of Expandable ListView: http://developer.android.com/reference/android/widget/ExpandableListView.html
For having an example, check this site: http://mylifewithandroid.blogspot.com/2008/05/expandable-lists.html
Pls, check the below image, do you want to perform as same ????
If you want to do the same, it is already given in the "API-Demos" at Views/Expandable Lists/1. Custom Adapter.
Enjoy !!
The problem is that you cannot use the standard ListView in your case, because in the standard ListView, the View of each row has to be one TextView.
In your case, you need it to be at least two TextViews (The standard Text, and the one that's gonna show up onClick/onFocus).
You have to create your custom ListAdapter, and override the getView() function.
Here is a code snippet that shows how to do it properly:
Custom Adapter
In the getView(), you have to inflate the XML file that describes your List Row, and return it.
In your case, I believe your XML file should contain 2 TextViews, one visible and one invisible.
Then, to handle the clicks, you can set a onItemClickListener on your ListView in your Activity class.
The best way may be to have your Activity class implementing onItemClickListener, and to use this onItemClickListener to handle those.
In the onClick() function, you just have to set the Visibility of your hidden TextView to VISIBLE.
You need to build custom rows, and handle showing more text on each row, there is no easy magicall way of doing it, but inflating your own rows, and setting a couple of attributes visibility isnt all that hard either.
I wish to work with checked list views wherein only one item can be selected at a time. Some queries related to this:
Is it advised to work with CheckedTextView as the ListView items, or a combination of CheckBox and TextView?
If using CheckedTextView, the text comes first and the checkbox appears on the right edge. Is it possible to make the checkbox appear on the left of the TextView?
How can I make one of the items as checked in onCreate()?
Note: I am using array adapter and calling setAdapter() to populate list.
You need to extend ArrayAdapter and use LayoutInflater to inflate the row layout as you need. This way you have full flexibility in list creation.
Please check this example, where basic idea is described:
