How to update checked custom listview record in android sqlite database?

Question

I have a custom listview with sqlite data. Listview contains 3 textviews and one checkbox. I want to update my sqlite database with a value for the checked items in listview. I have done almost steps but when I selected 2 items and tried to update, it updates only one record in sqlite database. I want to update the selected records. My code and Screen is given. I want to perform this on save button click. The selected listitems id from sqlite is storing in str1 variable.

btnSaveCancellation.setOnClickListener(new OnClickListener()
    {           
        @Override
        public void onClick(View v) 
        {                                           
            long itemCount = listVCancelCollection.getCount();

            for(i=0;i<=itemCount-1;i++)
            {
                if(chkConfirm.isChecked())
                {                   
                    final long str1 = list_collection.get(i).getId();       

                    AlertDialog.Builder alertDialogBuild=new AlertDialog.Builder(CancelCollection.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
                    alertDialogBuild.setTitle("Cancel Collection?");
                    alertDialogBuild.setCancelable(false).setPositiveButton
                    ("Yes", new DialogInterface.OnClickListener() 
                    {
                        @Override
                        public void onClick(DialogInterface dialog, int which)
                        {
                            dialog.cancel();

                            displayReasonPopup();                                           
                        }

                    private void displayReasonPopup()

                        alertDialogBuilder.setView(promptView);
                        alertDialogBuilder.setTitle("Reason");

                        final EditText editReason = (EditText) promptView.findViewById(R.id.edittext_reason);

                                String strUpdate="UPDATE Customer_Collection SET Collection_Status = '0' , "

                                db.endTransaction();  

                            }

您需要检查if(chkConfirm.isChecked())是否属于您的列表视图项
