private String getKeyboardLanguage() {

我想你想获得软件键盘语言的语言。您可以使用 InputMethodManager获取有关 Android 中输入类型的信息。

private String getKeyboardLanguage(){
    String language = "";

    // This will give you to access input method manager
    InputMethodManager im = (InputMethodManager)Context.getSystemService(Context.INPUT_METHOD_SERVICE);

    // Input methods has several subtypes, this will return the active one
    InputMethodSubtype subtype = im.getCurrentInputMethodSubtype();

    if(subtype != null){ // subtype can be null
        // Returns BCP-47 Language Tag or returns empty string if not specified
        language = getLanguageTag();
    }
    return language;
}
