I am new to android and I am starting a new Application in which I have to list down some users. The list includes image, name and mobile number and the list also include a checkbox. The checkbox has to be enable only when I click on a button like 'Download'. So far I have the listview with checkbox. My question is how can I enabled the checkbox only when I click on 'download' button? And also how can I capture the state of Checkbox? Any help will be appriciate. Thanks...
try looking in this tutorial http://www.softwarepassion.com/android-series-custom-listview-items-and-adapters. This is where I lernt how to do this...
You will need a custom listview in Android.
Fist learn the basics of ListView in Andriod here Then learn
about custom ListView here
Then learn more about ListView here and also here
Then implement your own listview
Wish you all the best.

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.
Hello guys I am new on android programming.I want to create a shopping list app so the idea is first. This is my idea :
There is no list then when I click the Add Button
I can give a name to the list and after that add it ( where I can fill this list with products to buy later )
The problem I have is:
I can't find an idea how to create a list when I click a button like this image :
How can I create more than one list and show them like the picture below.
I don't need code, I just the idea and I will search for the rest myself. I already look everywhere but couldn't find solution for it. Thank you guys.
You don't really have to createp a list if you click the button. You have to create the list in the UI or the xml files. If you click the add button, what you want to happen is to add data for the list to display. If you don't know about ListViews and how to add data to them using adapters, I suggest reading more on the topic:http://www.vogella.com/tutorials/AndroidListView/article.html
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 ?
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 have an expandablelistview that works fine. Now I want to export the data of expandable listview and I want the user to be able to choose (or check like there be a checkbox or something) which items of listview to export. How can I do that? Can anyone give me a solution please? I have searched the net but didn't find something useful.
P.S: I have an idea, Can I place a checkbox in explistview rows and set actions to them?
Thanks so much in advance
This is not possible with a normal expandablelistview.
You have to implement the logic yourself in OnChildItemClickListener.
For an example look here: https://github.com/jiahaoliuliu/ExpandableListViewWithChoice
In my application, i want to create a option menu for each item of listview, it's look like following link image. Thank for helping!
That looks very close to a Spinner ( http://developer.android.com/guide/topics/ui/controls/spinner.html ). Although I have not tried, I am sure there is a way to have a spinner perform actions using the OnItemSelected class similar to a listview. Simply populate it how you want and take the returned position to run a specific function.
You can use Expandable listview in android..
