android - 创建 AlertDialog 时会触发什么方法？

Question

什么方法触发 AlertDialog 创建？

像 Activity 的onCreate()， 我的情况:我有一个 fragment ，在这个 fragment 中我有一个带有此 setOnClickListener() 方法的按钮:

btnAddPromotionAw.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

            AlertDialog.Builder builder = new AlertDialog.Builder(
                    getActivity());

            LayoutInflater inflater = (LayoutInflater) getActivity()
                    .getSystemService(getActivity().LAYOUT_INFLATER_SERVICE);

            View dialog = inflater.inflate(R.layout.promotion_aware_picker,
                    null);
            builder.setView(dialog);

            final AlertDialog alertDialog = builder.create();
            alertDialog.show();

            alertDialog.getWindow().setLayout(600,400);

          }         
    });

我想在上面的 AlertDialog 创建中执行下面的代码:

ArrayList<Goods> Goodslist = new ArrayList<Goods>();
                            Goodslist = promotionAwAccess
                                    .getGoodsByIsMerch();

                            LinearLayout ll1 = (LinearLayout) alertDialog
                                    .findViewById(R.id.linearLayoutPAGoods);

                            final RadioButton[] rdb = new RadioButton[Goodslist.size()];
                            RadioGroup rdg = new RadioGroup(getActivity());
                            rdg.setOrientation(RadioGroup.VERTICAL);
                            rdg.setGravity(Gravity.RIGHT);

                            for (int i = 0; i < Goodslist.size(); i++) {

                                rdb[i] = new RadioButton(getActivity());
                                rdg.addView(rdb[i]);
                                rdb[i].setText(Goodslist.get(i)
                                        .getGoodsName());
                                rdb[i].setId(i);
                                rdb[i].setButtonDrawable(android.R.color.transparent);
                                rdb[i].setCompoundDrawablesWithIntrinsicBounds(
                                        0, 0, R.drawable.btn_radio_custom,
                                        0);

                            }
                            ll1.addView(rdg);

抱歉一开始解释不完整。

AlertDialog.Builder builderSingle = new AlertDialog.Builder(
                    DialogActivity.this);
            builderSingle.setIcon(R.drawable.ic_launcher);
            builderSingle.setTitle("Select One Name:-");
            final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
