is there a way OTHER than checking the input and determine which language is he typing?

Answer 1

通过搜索 react native 文档https://facebook.github.io/react-native/docs/keyboard.html没有提供键盘实际语言的属性或函数，但您可以通过实现一个在您的 java 或 Objective-C 代码中的函数

您可以在此处了解如何添加您的个人本机代码并将其用于本机反应： https ://facebook.github.io/react-native/docs/native-modules-android.html

然后只需将此方法添加到您的“MyCustomKeyboard”类（java）上：

@ReactMethod
public String getKeyboardLanguage() {
  InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
  InputMethodSubtype ims = imm.getCurrentInputMethodSubtype();
  String locale = ims.getLocale();
  return locale;
}
