获取键盘语言或检测用户输入语言的Andr​​oid [英] Get keyboard language or detect user input language in Android

问题描述

我想检测键盘的当前选择的语言。为了这个目的我用下面的code：

I'm trying to detect current selected language of the keyboard. For that purpose I use following code:

/* Return the handle to a system-level service by name. The class of the returned
 * object varies by the requested name. */
 InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
/* Returns the current input method subtype. This subtype is one of the subtypes in the
 * current input method. This method returns null when the current input method doesn't
 * have any input method subtype. */
 InputMethodSubtype ims = imm.getCurrentInputMethodSubtype();
/* The locale of the subtype. This method returns the "locale" string parameter passed
 * to the constructor. */
 String locale = ims.getLocale();

但应用阵痛的NoSuchMethodError 的异常 getCurrentInputMethodSubtype 功能。

有没有什么办法让键盘选择的语言？如果没有我怎么可以检测所用的语言输入用户在应用程序？

Is there any way to get Keyboard selected language? If no how I can detect the language in which user typing in the application?

推荐答案

下面是我所做获得可用的输入语言：

Here's what I did to get the available input languages:

    private void printInputLanguages() {
       InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
       List<InputMethodInfo> ims = imm.getEnabledInputMethodList();

       for (InputMethodInfo method : ims){
           List<InputMethodSubtype> submethods = imm.getEnabledInputMethodSubtypeList(method, true);
           for (InputMethodSubtype submethod : submethods){
              if (submethod.getMode().equals("keyboard")){
                 String currentLocale = submethod.getLocale();
                 Log.i(TAG, "Available input method locale: " + currentLocale);
              }
           }
    }
}
