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.

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:

I have a ListView that is clickable in a class(a new activity is opened, when you click on it), that extends ListActivity.This List get's filled through an arrayAdapter. Now I've tried to make the list checkable by implementing "android.R.layout.simple_list_item_single_choice" in the second Parameter of the ArrayAdapter Constructor. So the checkbox has arrived, but when I click on it, the activity is opened, but the checkbox isn't checked. To solve this issue, I`ve set the Parameters "focusable" and "focusableInTouchMode" of the ListLayout to false. But this hasn't worked either. I guess, that I have a problem with the focusable Parameter, but I think I have to change it anywhere else. But because the arrayAdapter takes away the work to define a layout for a single ListItem, I don't know where to do this. When I try to define a layout with a checkbox on my own, I get the error, that an ArrayAdapter requires the resource ID of the layout to be a TextView. So
Is it possible to solve this problem with an ArrayAdapter?
If yes, how can I solve it?
I appreciate your suggestions
Is it possible to have some listview rows have a checkbox, or a switch and others to nothing just a title and remain clickable.
I am trying to a do a listview that has a few different settings.
First - Checkbox
second - Switch
Third - Just list.
I know I could do them as separate buttons I would like to have them filled from the same array if possible?
YES Definately Its possible...
1. Create a custom layout for ListView or RecyclerView row item with CheckBox, Switch, TextView or other views as per your requirement.
2. Create a custom adapter extending from ArrayAdapter, BaseAdapter or RecyclerView.Adapter to populate list data to your custom layout.
3. In getView() or onBindViewHolder() method, set data to your views and add required OnClick or OnCheckedChange listener to your Views.

Hope this will help~
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'm trying to add a CheckBox to every item in my ListView. I can't put a CheckBox widget in the ListView, so how do I do it? I think the Android settings has something like this.
Off the top of my head, you should create an xml layout file representing an item in the ListView, in which you would declare a CheckBox. You can then set the adapter to use your layout for every item as follows:
ArrayAdapter<T> adapter = new ArrayAdapter<T>(this, R.layout.list_item, listReference);
setListAdapter(adapter);
setListAdapter is a method in ListActivity. Your list_item.xml should have the CheckBox defined in it.
You need to extend a view adapter class and provide your own logic for creating the views for each row. Here's an excerpt from an android development book at commonsware.com that might help.
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.
