android 對話框使用

自己做了一個對話框的demo，熟悉了一下Android對話框的實現。

apiDemo中有這樣的例子。

new AlertDialog.Builder(DialogDemo.this)
                    .setIcon(R.drawable.icon32)
                    .setTitle(R.string.alert_dialog_two_buttons_msg)
                    .setMessage(R.string.alert_dialog_two_buttons3_msg)
                    .setPositiveButton(R.string.alert_dialog_yes,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {

                                    /* User clicked OK so do some stuff */
                                }
                            })
                    .setNegativeButton(R.string.alert_dialog_no,
                            new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog,
                                        int whichButton) {

                                    /* User clicked OK so do some stuff */
                                }
                            })
                    .create();

setIcon使用圖標，setTitle（）設置標題；setMessage（）設置顯示對話框內容；setPositiveButton設置第一個按鈕，第一個屬性是設置按鈕內容，第二個屬性是設置點擊之後的事件；setNegativeButton設置第二個按鈕與第一個按鈕設置一樣。
