public static void setHideInputMethod(Activity context) {

try {

InputMethodManager inputMethodManager = (InputMethodManager) context

.getApplicationContext().getSystemService(

Context.INPUT_METHOD_SERVICE);

inputMethodManager.hideSoftInputFromWindow(context

.getCurrentFocus().getWindowToken(),

InputMethodManager.HIDE_NOT_ALWAYS);
