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 am creating a costum ListView
In this ListView I have the a list.xml with an item which has an image and three text fields.
Now to my problem :P
How can I add this custom ListView ITEM to my ListView (after a Button from another activity is clicked) and save it somewhere like in SQL...
Don't use ListView. Use RecyclerView instead.

You need to create adapter where you point proper XML file for an item
1. First, create a custom layout XML for your list row item(Image and 3 TextViews).
2. Create a custom adapter class to populate your ArrayList<OBJECT> on custom list row XML.
Here are some good tutorials:
Android Custom ListView with Image and Text
Android Custom ListView with Image and Text using Volley
Android Working with Recycler View
FYI, You can use RecyclerView instead of ListView. Android RecyclerView is more advanced version of ListView with improved performance and other benefits.
Hope this will help~
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.
Here are some tutorial link:

Android RecyclerView with CheckBox

I am working Android application, Using ListActivity to create ListView then i tried to add ToggleButton inside the ListItems, but i didn't know that, please help me
Thanks in Advance
Here are the steps by which you can create Custom ListView:
Create row layout for your listview item which you want for ListView
create custom adapter by creating a separate class, and extend BaseAdapter
Override getView() method, inflate the above item row layout and display the data
For more info: android custom listview And if you want to learn about: AdapterViews and Adapters
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
My activity has a spinner and a custom ListView and they are both sourced by custom ArrayAdapters (ArrayList of custom objects). The ListView rows are custom views (just 2 TextViews).
When I include the line, spinner.setAdapter(spinnerArrayAdapter); the ListView is NOT filled with data on the screen and the spinner contains the values I want.
When I remove the line, spinner.setAdapter(spinnerArrayAdapter); the ListView is filled with the data I want and the spinner does NOT contain any values.
When I debug, I see the data in the ListView's custom ArrayAdapter variable and the spinner's custom ArrayAdapter.
I have checked my getView() implementation for the ListView's custom ArrayAdapter class.
Suggestions?
Thanks in advance!
Can you paste some code to help identify the problem. I tested with two listviews and a spinner pointing to the same adapter. It worked fine for me.
