1.加载初始桌面布局camera_ui_root，对应 quick_switcher
2.加载quick_switcher相关布局QuickSwitcherManager? setVisibility
3.加载flash相关图标布局FlashViewController，mMainHandler.sendEmptyMessage(FLASH_VIEW_INIT);
4.初始化：initFlashEntryView，flash_icon.xml
5.通过mSettingController.addViewEntry();将其加入到 quick_switcher 中。
6.点击相应图标触发 mFlashEntryListener 事件，加载布局
7.触发 mFlashChoiceViewListener 点击事件重新加载布局
