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](/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.

## 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 '.

`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` 。
