Answer 1

Use isItemChecked (int position) or setItemChecked(int position, boolean value) if you using standart array adapter and SINGLE or MULTIPLE choise mode. http://developer.android.com/reference/android/widget/AbsListView.html#isItemChecked(int)

Also you can create your custom adapter and inflate row layout with checkbox that can hold onClickListener and CheckedChangedListener. Use search to find example.

Answer 2

Set onlistitemclick listener to listview , then in itemclick method you can get mylistView.getCheckedItemCount() , write the code of the operation to be performed.

If this is not clear let me know what you want to implement when item is checked.

mylistView = (ListView)customView.findViewById(R.id.mylist);
mylistView.setAdapter(mFolderAdapter);

mylistView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);


mylistView.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> arg0, View v,
                        int arg2, long arg3) {
                    // TODO Auto-generated method stub



                        if(mylistView.isItemChecked(arg2)){

  //Dooperation

                            } 
// or 
if(mylistView.getCheckedItemCount()>1){
  //Dooperation
}

                }
            });
