create a list with multiple parameters on a line android

Question

I am new to android. I would like to create an array list that contains 4 parameters: name phone number, type of call, data, but i don't know how to do it. Can someone please help me?

Secondly I would like to ask what is the difference between list and listadapter ?

I mean I need something like this. I need to create an array that is going to print in a log file the first element[1]...second and so on. The first element is an array of 4 parameters(name,phone,type,data). => array of objects.!

when you say an array list with 3 parameter do u mean an arraylist of arrays or do u intend to make a listview which displays these 3 parameters in one list element? — Anurag Ramdasan

you could make for example a class called PhoneCall:

class PhoneCall{
     String name;
     String number;
     String type;
     String date;

     PhoneCall(String name, String number, String type, String date)
     {
         this.name = name;
         this.number = number;
         this.type = type;
         this.date = date;
     } 
    //getters and setters here
}

and then make arraylist:

ArrayList<PhoneCall> list = new ArrayList<PhoneCall>();

and add new items to it:

list.add(new PhoneCall(name,number,type,date));

i believe what you are looking for is called a custom list view. it involves using a list adapter to give a custom layout for your listview. the layout for every single element can be designed using a separate layout xml file and the addded to the list view. you can refer this to get an idea.

also a listview is a layout element that is used to display data in a list format while a list adapter is the bridge between the listview and the data that is backed in the list. i hope that solved your doubt.

What you should do here is to create a class that wrap all fields you mentions name phone number, type of call, data). Then , simply create a List ( implement ArrayList for instance), then add objects of the type you has just defined. Simple and clear, right ?

For your second question, I don't know what you mean by list. You mean ListView in Android or List- a java datatype. So in the context of Android programming, I consider list here is ListView :) ListView is a view that contain many 'item' inside. The way you populate data to ListView could be decided by ListAdapter. For more, just refer ListView Tutorial from Android developer site
