Get keyboard language or detect user input language in Android

Question

Problem Description

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

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();

but application throes NoSuchMethodError exception on getCurrentInputMethodSubtype function.

Question

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

Answer 1

You can get keyboard language by first detecting the locale of device keyboard and then getting the Locale object from it. For example,

    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
    InputMethodSubtype ims = imm.getCurrentInputMethodSubtype();
    String localeString = ims.getLocale();
    Locale locale = new Locale(localeString);
    String currentLanguage = locale.getDisplayLanguage();

Here, currentLanguage will give your keyboard language. Hope this helps.

1st Method

To get the selected language of your device. This might help u

Locale.getDefault().getLanguage()        ---> en     
Locale.getDefault().getISO3Language()    ---> eng
Locale.getDefault().getCountry()         ---> US
Locale.getDefault().getISO3Country()     ---> USA
Locale.getDefault().toString()           ---> en_US
Locale.getDefault().getDisplayLanguage() ---> English
Locale.getDefault().getDisplayCountry()  ---> United States
Locale.getDefault().getDisplayName()     ---> English (United States)

2nd Method

You can extract the language from the current locale. You can extract the locale via the standard Java API, or by using the Android Context. For instance, the two lines below are equivalent:

String locale = context.getResources().getConfiguration().locale.getDisplayName();
String locale = java.util.Locale.getDefault().getDisplayName();
