You can think of `lv_ime_pinyin` as a Pinyin input method plug-in for keyboard objects. + +Normally, an environment where [lv_keyboard](/widgets/extra/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](/widgets/extra/keyboard)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)。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](/widgets/extra/keyboard)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](https://baike.baidu.com/item/%E6%B1%89%E8%AF%AD%E6%8B%BC%E9%9F%B3%E9%9F%B3%E8%8A%82/9167981) to learn about the Hanyu Pinyin syllables and the syllable table. + +Then, write your own dictionary according to the following format: + +
+中文 +

+ +**注意**，各个拼音音节的排列顺序非常重要，您需要按照汉语拼音音节表定制自己的词库，可以阅读[这里](https://baike.baidu.com/item/%E6%B1%89%E8%AF%AD%E6%8B%BC%E9%9F%B3%E9%9F%B3%E8%8A%82/9167981)了解[汉语拼音音节](https://baike.baidu.com/item/%E6%B1%89%E8%AF%AD%E6%8B%BC%E9%9F%B3%E9%9F%B3%E8%8A%82/9167981)以及[音节表](https://baike.baidu.com/item/%E6%B1%89%E8%AF%AD%E6%8B%BC%E9%9F%B3%E9%9F%B3%E8%8A%82/9167981#1)。 + +然后，根据下面的格式编写自己的词库： + +

+
+ +```c +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： + +
