Pinyin IME
Pinyin IME provides API to provide Chinese Pinyin input method (Chinese input) for keyboard object, which supports 26 key and 9 key input modes. You can think of lv_ime_pinyin as a Pinyin input method plug-in for keyboard objects.
Normally, an environment where lv_keyboard can run can also run lv_ime_pinyin. There are two main influencing factors: the size of the font file and the size of the dictionary.
中文
lv_ime_pinyin为键盘组件提供汉语拼音输入法（中文输入）的功能(后文简称为拼音输入法)，支持26键和9键输入模式。您可以将 lv_ime_pinyin 看成是键盘组件的汉语拼音输入法插件。
一般情况下，只要是键盘组件能运行的环境 lv_ime_pinyin 也能运行。有两个影响因素：字库的大小和词库的大小。
Usage
Enable LV_USE_IME_PINYIN in lv_conf.h.
First use lv_ime_pinyin_create(lv_scr_act()) to create a Pinyin input method plug-in, then use lv_ime_pinyin_set_keyboard(pinyin_ime, kb) to add the keyboard you created to the Pinyin input method plug-in.
You can use lv_ime_pinyin_set_dict(pinyin_ime, your_dict) to use a custom dictionary (if you don't want to use the built-in dictionary at first, you can disable LV_IME_PINYIN_USE_DEFAULT_DICT in lv_conf.h, which can save a lot of memory space).
The built-in thesaurus is customized based on the LV_FONT_SIMSUN_16_CJK font library, which currently only has more than 1,000 most common CJK radicals, so it is recommended to use custom fonts and thesaurus.
In the process of using the Pinyin input method plug-in, you can change the keyboard and dictionary at any time.
中文
在 lv_conf.h 中打开 LV_USE_IME_PINYIN。
首先，使用 lv_ime_pinyin_create(lv_scr_act()) 函数创建一个拼音输入法插件，
然后使用 lv_ime_pinyin_set_keyboard(pinyin_ime, kb) 函数将您创建的键盘组件添加到插件中。
内置的词库是基于 LVGL 的 LV_FONT_SIMSUN_16_CJK 字库定制，这个字库目前只有 1000 多个最常见的 CJK 部首，所以建议使用自定义字库和词库。
您可以使用 lv_ime_pinyin_set_dict(pinyin_ime, your_dict) 函数来设置使用自定义的词库，如果您一开始就不打算使用内置的词库，建议您在 lv_conf.h 中将 LV_IME_PINYIN_USE_DEFAULT_DICT 关闭，这可以节省一些内存空间。
Custom dictionary
If you don't want to use the built-in Pinyin dictionary, you can use the custom dictionary. Or if you think that the built-in phonetic dictionary consumes a lot of memory, you can also use a custom dictionary.
Customizing the dictionary is very simple.
First, set LV_IME_PINYIN_USE_DEFAULT_DICT to 0 in lv_conf.h
Then, write a dictionary in the following format.
中文
如果您不想使用内置的词库，可以通过下面的方法自定义词库。
自定义词典非常简单。
首先，在 lv_conf.h 将 LV_IME_PINYIN_USE_DEFAULT_DICT 设置为 0。
然后按照下面的格式编写词库。
Dictionary format
The arrangement order of each pinyin syllable is very important. You need to customize your own thesaurus according to the Hanyu Pinyin syllable table. You can read here to learn about the Hanyu Pinyin syllables and the syllable table.
Then, write your own dictionary according to the following format:
lv_100ask_pinyin_dict_t your_pinyin_dict[] = {
{ "a", "啊阿呵吖" },
{ "ai", "埃挨哎唉哀皑蔼矮碍爱隘癌艾" },
{ "an", "按安暗岸俺案鞍氨胺厂广庵揞犴铵桉谙鹌埯黯" },
{ "ang", "昂肮盎仰" },
{ "ao", "凹敖熬翱袄傲奥懊澳" },
{ "ba", "芭捌叭吧笆八疤巴拔跋靶把坝霸罢爸扒耙" },
{ "bai", "白摆佰败拜柏百稗伯" },
/* ...... */
{ "zuo", "昨左佐做作坐座撮琢柞"},
{NULL, NULL}
The last item must end with {null, null} , or it will not work properly.
Apply new dictionary
After writing a dictionary according to the above dictionary format, you only need to call this function to set up and use your dictionary:
中文
按照上面的词库格式编写好自己的词库之后，参考下面的用法，调用 lv_100ask_pinyin_ime_set_dict(pinyin_ime, your_pinyin_dict) 函数即可设置和使用新词库：
lv_obj_t * pinyin_ime = lv_100ask_pinyin_ime_create(lv_scr_act());
lv_100ask_pinyin_ime_set_dict(pinyin_ime, your_pinyin_dict);
Input modes
lv_ime_pinyin supports 26 key and 9 key input modes. The mode switching is very simple, just call the function lv_ime_pinyin_set_mode. If the second parameter of function lv_ime_pinyin_set_mode is' 1 ', switch to 26 key input mode; if it is' 0', switch to 9 key input mode, and the default is' 1 '.
中文
lv_ime_pinyin 支持26键和9键输入模式。模式的切换非常简单，只需调用函数 lv_ime_pinyin_set_mode 即可。如果函数 lv_ime_pinyin_set_mode 的第2个参数为 1 则切换到 26 键输入模式，如果为 0 则切换到 9 键输入法模式，默认为 1 。
