I have created search on listview,but row selection get effected while search,I assume selection is maintained based on index.Can any one explain best way to solve this problem.
you may set different custom id or setTag to listview elements after clickListener you can get that custom id or tag so you can check which item is clicked.
View v;
v.setId();
v.setTag();

I create a dynamic custom listview that contain some elements like button ImageView and etc using custom adapter cursor adapter. this is problem when i click on any button because of duplicate id i lost my specific button. i have set tag for each button and is correct but i can't find my button id.
Also i use "button.setID()" but is not worked in some elemnts.
How can I set unique id for views (like button) in this case?
(In the general view I want work with any element in my listview separately )
You don't need different button(any view) ids... Just access the item with Position and find the view with ID.
Kindly read and understand the docs before apply..
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 had a custom listview with checkbox in alert dialog. I want to access the row with selected checkbox on Done button click. Here is the screen short of the image.
Here I'm using hash map both arguments string with custom list
Thanks in Advance
One way could be set a listener to your CheckBoxes and add/remove the row (object, view or whatever you need) to a list when the check changes.
Another way to achieve this could be to iterate over your rows and see if the CheckButton is checked or not. But this choice won't be good in performance if you have too many rows.
I have a View with a ListView appended, which actually uses a custom view item done programatically. Inside each list item I have a button which I need to track, to update another item in the view. It is only invalidated when you click on the list item button, not anywhere else in the list item.
So I thought of creating a custom Listener. I trigger it when the button is clicked, but I have no way to access it from the ListView activity.
Is there a way to simulate those setOnItem...Listener's using a custom listener? Thanks in advance
Please see this link to help with how to set onClickListener from within custom ListAdapters.
You can use the myButton.getTag() and myButton.setTag() to put and get data to/from your View/Button.
See this link as well to help with custom ListAdapters.
Here is another good example I found of how to use a custom adapter.
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:
