//  showing alert dialog
private void showAlertDialog(int pos, String optionTxt) {
        final EditText edittext = new EditText(getApplicationContext());
        final AlertDialog dialog = new AlertDialog.Builder(this)
                .setTitle(getString(R.string.optionSpace) + (pos + 1))
                .setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        System.out.println("ding! Ok clicked!");
                    }
                })
                .setView(edittext)
                .setNegativeButton("Cancel", null)
                .show();
        // this is VERY IMPORTANT -> ALWAYS APPLY THE TRICK ONLY AFTER .show() YOUR DIALOG

//  prevent from orientation change
