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

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~
I would like to know what is the diff b/w listview and listactivity. According to my understanding, if we have only list in a screen then better to use listactivity correct?.
If we want to add either simple button at the bottom of list or include search on top of list, then we should use listview in layout file right?
List activity is the activity which has a listview as its layout by default... and you can even customise the listview in the ListActivity by using a layout inflater and adding views...and yes.. for simple listview use list activity.. and to add such components use listview in layout..
To customise your rows in list use listactivity like this..
I am trying to have a layout with 6 TextViews and a Custom List.
TextView number 3,4,5 have images next to them,followed by the Custom List.
The custom list is done , but I am not sure how I can get the upper part ( TextView controls and images ) and the custom list in one layout.
For other custom lists I have always extended from ListActivity and set the list adapter in the same class as it is the only control on the screen.
In this case the class extends from Activity,how can I set the list adapter in the Activity class ?
Any pointer's to achieve this layout and which layout will be the optimal choice(Linear,Relative..) ?
Thanks,

I found the answer to my problem.
Add a listview to the layout xml
Get the listview object using findViewById
User etAdapter to set the custom list adapter
Now I can use the custom list along with other controls in the same Activity.

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 m in little problem
