mtk平台mmi培训资料(中文)2021-06-0621:48本文具体讲明了如何建设一个自定义列表窗体模板。

原理局部请参见?MTK平台(1)——如何添加一个窗体模板?。

最终实现的是一个字典输进界面。

布局为：该模板不包含业务逻辑，仅提供页面显示和InputBox框输进事件后的ListBox的Redraw事件的注册，以及全然的输进法设置、清空后的返回函数。

一、添加用户自定义列表模板的过程〔一〕在g_categories_controls_map[]中参加：,{MMI_CATEGORY_CUSTOM_LIST,(U8*)custom_define_list,(s16*)coordinate_c ustom_list,NULL}constU8custom_define_list[]={5,DM_BASE_LAYER_START,DM_SCR_BG,DM_BASE_CONTROL_SET1,DM_SINGLELINE_INPUTBOX1,DM_LIST1};constS16coordinate_custom_list[]={DM_FULL_SCREEN_COORDINATE_FLAG,DM_CUSTOM_DEFINE_INPUTBOX, //需要定义DM_CUSTOM_DEFINE_LIST //需要定义};〔二〕在dm_get_coordinates〔〕函数中参加：//设定列表位置和大小〔不要不记得全局变量MMI_custom_Listbox_x等的定义〕elseif(*UICtrlAccessPtr_p==DM_CUSTOM_DEFINE_LIST){dm_coordinate_info->s16X=MMI_custom_Listbox_x;dm_coordinate_info->s16Y=MMI_custom_Listbox_y; dm_coordi nate_info->s16Width=MMI_custom_Listbox_width; dm_coordinate_info-> s16Height=MMI_custom_Listbox_height;dm_coordinate_info->Flags=DM_NO_FLAGS;UICtrlAccessPtr_p++;}//设定输进框位置和大小elseif(*UICtrlAccessPtr_p==DM_CUSTOM_DEFINE_INPUTBOX){dm_coordinate_info->s16X=MMI_custom_inputbox_x;dm_coordinate_info->s16Y=MMI_custom_inputbox_y;dm_coordinate_info->s16Width=MMI_custom_inputbox_width;dm_coordinate_info->s16Height=MMI_custom_inputbox_height; dm_coo rdinate_info->Flags=DM_SINGLE_LINE_INPUTBOX_SPECIFIC_HEIGHT;UICtrlAccessPtr_p++;}〔三〕在Wgui_category.c中定义模板显示函数voidShowCategoryCustomListScreen(U8*title,U16title_icon,U16left_softkey,U16left_softkey_icon,U16right_softkey,U16right_softkey_icon,S32number_of_items,U8**list_of_items,U16*list_of_icons,S32flags,S32highlighted_item,U8*history_buffer){/*----------------------------------------------------------------*//*LocalVariables*//*----------------------------------------------------------------*/dm_data_structdm_data;S32i;U8h_flag;/*----------------------------------------------------------------*//*CodeBody*//*----------------------------------------------------------------*/gdi_layer_lock_frame_buffer();SetupCategoryKeyHandlers();MMI_title_string=(UI_string_type)title;MMI_title_icon=(PU8)get_image(title_icon);change_left_softkey(left_softkey,left_softkey_icon);change_right_softkey(right_softkey,right_softkey_icon);//CreateListcreate_fixed_icontext_menuitems();associate_fixed_icontext_list();ShowListCategoryScreen((UI_string_type)title,get_image(title_icon),get_string(left_softkey),get_image(left_softkey_icon),get_string(right_softkey),get_image(right_softkey_icon),number_of_items);for(i=0;i<number_of_items;i++){add_fixed_icontext_item((UI_string_type)list_of_items[i ],wgui_get_list_menu_icon(i,list_of_icons[i]));}h_flag=set_list_menu_category_history(MMI_CATEGORY_CUSTOM_LIST, history_buffer);if(h_flag){fixed_list_goto_item_no_redraw(MMI_fixed_list_menu.high lighted_item);}else{fixed_list_goto_item_no_redraw(highlighted_item);}//CreateInputboxmemset(custom_single_input_buffer,0,100);pfnUnicodeStrcpy(custom_single_input_buffer,L"CustomCategory");=MMI_CATEGORY_CUSTOM_LIST;//不要不记得该常量MMI_CATEGORY_CUSTOM_LIST的定义dm_data.s32flags|=DM_CLEAR_SCREEN_BACKGROUND;//dm_data.s32flags|=DM_SHOW_VKPAD;dm_register_vkpad_callback(CustomList_virtual_keypad_callback);dm_setup_data(&dm_data);dm_redraw_category_screen();} /*endofShowCategory353Screen*/voidCustomList_virtual_keypad_callback(void){#ifdefined(__MMI_TOUCH_SCREEN__)mmi_pen_editor_clear_and_show_virtual_keyboard_area();#endifgui_show_transparent_image(0,200,GetImage(IMG_H_SELECT_LEFT),0); }voidExitCategoryCustomListScreen(){wgui_close_singleline_inputbox();}〔四〕在singleline_inputbox_multitap_input〔〕函数中添加用户处理key_0~key_9的按键事件的函数：void(*singleline_inputbox_custom_input_callback)(void)=UI_dummy_funct ion;voidsingleline_inputbox_multitap_input(UI_character_typec){/*----------------------------------------------------------------*//*LocalVariables*//*----------------------------------------------------------------*//*----------------------------------------------------------------*//*CodeBody*//*----------------------------------------------------------------*/if(MMI_singleline_inputbox.flags&UI_SINGLE_LINE_INPUT_BOX_PLUS_ CHARACTER_HANDLING){if((MMI_singleline_inputbox.text[0]=='+')&&(MMI_singleline_inputbox.current_text_p==MMI_si ngleline_inputbox.text)&&(MMI_singleline_inputbox.text_length>=(MMI_sing leline_inputbox.available_length-ENCODING_LENGTH))){return;}}gui_single_line_input_box_insert_multitap_character(&MMI_single line_inputbox,c);redraw_singleline_inputbox();singleline_inputbox_input_callback();singleline_inputbox_custom_input_callback();}〔五〕Wgui_Category.c中添加用户事件定义接口//右键事件注册voidSetCategoryCustomListRightSoftkeyFunction(void(*f)(void)){wgui_singleline_inputbox_RSK_function=f;}//key_0到key_9按下时的事件注册externvoid(*singleline_inputbox_custom_input_callback)(void); voidSetCategoryCustomListNumKeyFunction(void(*f)(void)){singleline_inputbox_custom_input_callback=f;}//设置InputBox大小voidSetCustomList_Inputbox_Size(S32p_x,S32p_y,S32p_width,S32p_height) {MMI_custom_inputbox_x=p_x;MMI_custom_inputbox_y=p_y;MMI_custom_inputbox_width=p_width;MMI_custom_inputbox_height=p_height;}//设置ListBox大小voidSetCustomList_Listbox_Size(S32p_x,S32p_y,S32p_width,S32p_height) {MMI_custom_Listbox_x=p_x;MMI_custom_Listbox_y=p_y;MMI_custom_Listbox_width=p_width;MMI_custom_Listbox_height=p_height;}二、自定义列表模板的使用方法1、调用SetCustomList_Inputbox_Size和SetCustomList_Listbox_Size设置列表框和输进框的大小。

安装完后将mfc patch中的文件拷入system32目录中。

4、下载线驱动：路径：mtk环境工具\6219B_USB_Line_Driver 2.0.1.1 (Recommend)prolific安装步骤：将下载线插入USB口中，弹出驱动安装窗口，安装提示将目录定位在上面得路径中按照提示安装即可。

、|!_一个人总要走陌生的路，看陌生的风景，听陌生的歌，然后在某个不经意的瞬间，你会发现，原本费尽心机想要忘记的事情真的就这么忘记了..MTK手机驱动培训资料【驱动部门的主要任务】驱动部门的主要任务是调试软件，让软件在硬件上顺利的跑起来。

其中包括各个具体的器件的调试以及一些和底层相关的问题，以及其他不属于mmi部分的问题。

具体的包括：1、LCD的调试：一般LCD厂商在提供样品的时候，都会提供给初始化代码，服务更好的还会提供进入和退出SLEEP的代码，如果厂商不提供的话，就只有看着文档自己写了。

我们的工作一般是调节显示效果以及和厂商沟通，还有就是把厂商给的代码整合进程序里面去。

Lcd驱动程序相关的文件主要包括lcd.c,lcd_sw.h以及lcd_sw_inc.h。

调节LCD的驱动程序，最先要在lcd_sw_inc.h中修改lcd的尺寸，就是LCD_WIDTH 和LCD_HEIGHT，如果有小屏的话还要定义下面的小屏的lcd的尺寸。

然后，根据硬件的设计修改lcd_sw.h中的宏，来确定lcd是使用8位的还是16位的接口，比如使用16位的lcd接口，就定义宏MAIN_LCD_16BIT_MODE。

最后,移植厂商给的初始化代码进入到初始化函数里,还有进入和退出Sleep状态。

进入和退出Sleep状态要求重新进入Sleep状态后屏幕能正常的显示，退出Sleep状态要求LCD 的耗电小于0.1ma。

如果是CSTN的屏幕，那么还有一个对比度的参数需要设定。

有2个对比度的值，一个是在初始化函数中写进去的一个值，还有一个是在nvram_user_config.c中的结构NVRAM_EF_CUST_HW_LEVEL_TBL_DEFAULT中定义。

2、GPIO的设定：GPIO就是General purpose IO pin的意思,是一些能用做一般的功能控制的IO引脚。

MTK 芯片的引脚一般有四个功能选项，可以通过寄存器来控制各个引脚的功能，一般功能0就是表示这个引脚用做GPIO。
