Answer 1

try using this one. You can pass ArrayList of class using Serializable interface. check below code.

1) you have to implement Serializable interface in your ContactListItems class like 

public class ContactListItems implements Serializable {

}

2) Pass arraylist of ContactListItems via intent:

Intent intent = new Intent(YourCurrentActivity.this, DestinationActivity.class);
intent.putExtra("ContactListData", arrayListData); //  here arrayListData is the object of ArrayList<ContactListItems>
startActivity(intent);

3) get Intent of ArrayList containing ContactListItems class:

ArrayList<ContactListItems> contactListData;

Bundle extras = getIntent().getExtras();
   if (extras != null) {
    contactListData = (ArrayList<ContactListItems>) extras
                    .getSerializable("ContactListData");

   }

Hope it will help you.

overide onitem click listener for ListView http://www.mkyong.com/android/android-listview-example/

you can use bundle and also you can use another class which have ArrayList contactList variable and in listview click retrive id of row and pass that id using bundle and there you go

Answer 3

If you want to fill your entity class with your Cursor you should use a for statement,now your are getting just the first row in your Cursor and reinstantiate your class

for(c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) 
{
}

and for your list listener use :

YourList.setOnItemClickListener(new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
            long arg3) {
    }});

Edit : this is the code how you put an arraylist to the intent

intent.putStringArrayListExtra("Tets",YourArrayList);
