I Solved and got the OrderId by using below code , this worked for me and i could retrieve the custom ORDERID which i passed to the list

                      int isSelectedOrderNumber=0;
          mOpenOrdersSelected = new ArrayList<OpenOrders>();              
                      StringBuffer sb = new StringBuffer();
          Iterator<OpenOrders> it = mOpenOrders.iterator();
          while(it.hasNext())
          {
              OpenOrders objOpenOrders = it.next();
              //Do something with objOpenOrders
              if (objOpenOrders.isSelected()) {
                  isSelectedOrderNumber++;
                  mOpenOrdersSelected.add(new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName()));
                  sb.append(objOpenOrders.getOrderID());
                  sb.append(",");
                }
             }

          //Below Condition Will Check the selected Items With parameter passed "mMAX_ORDERS_TOBEPICKED"
            if(isSelectedOrderNumber<1){
                ShowErrorDialog("Please Select atleast One order");
                return;
            }
            if(isSelectedOrderNumber>mMAX_ORDERS_TOBEPICKED){
                ShowErrorDialog(" Select Maximum of  "+mMAX_ORDERS_TOBEPICKED+ " Orders only to process");
                return;
            }
           Log.d(MainActivity.class.getSimpleName(), "cheked Order Items: " +sb);  
           Toast.makeText(getApplicationContext(), "cheked Order Items id:" +sb, Toast.LENGTH_LONG).show();

You just need to call ListView.getCheckedItemIds(). It will return a long[] with all checked ids. There is also ListView.getCheckedItemPositions() which will give you all checked positions.

Make sure you set ListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE) in onCreate() or whereever you set up your views (or in layout xml).

To get the checked values you just need to do this:

SparseBooleanArray checked = mListView.getCheckedItemPositions();
for (int i = 0; i < checked.size(); i++) {
    if (checked.valueAt(i)) {
        int pos = checked.keyAt(i);
        Object o = mListView.getAdapter().getItem(pos);
        // do something with your item. print it, cast it, add it to a list, whatever..
}

Jerry, set your order object as tag to the view which has selection event [CheckBox, TextView, Row view], when user select item you can get selected order object from tag and you can get any member of that object(order). for ex.

Order Object

Order {
int id;
String name;
boolean isSelected;

//add getters and setters
}

void getview(...) {
     View v = //inflate view
     CheckBox cb = (CheckBox) v.findViewById(..);
     cb.setTag(yourlist.get(position));
     cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

        @Override
        public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
             ((Order) buttonView.getTag()).setSelected(isChecked);
        }
     });

}
