Answer 1

Try this:

protected void hideSoftKeyboard(EditText mSearchView) {
    InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    mgr.hideSoftInputFromWindow(mSearchView.getWindowToken(), 0);
}

Answer 2

dialog.setOnDissmissListener(){
   void onDismiss(){

    inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
    inputManager.hideSoftInputFromInputMethod(getCurrentFocus().getWindowToken(), 0);

   }
} 
dialog.dismiss();

Answer 3

Try doing it the following way

final InputMethodManager inputManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

final AlertDialog alertDialog = new AlertDialog.Builder(SwipeActivity.this).create();
                  alertDialog.setTitle("Error");
                  alertDialog.setMessage("Name can't be emtpy");
                  alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
                      new DialogInterface.OnClickListener() {
                          public void onClick(DialogInterface dialog, int which) {

                                 inputManager.hideSoftInputFromInputMethod(alertDialog.getCurrentFocus().getWindowToken(), 0);
                                 dialog.dismiss();

                          }
                  });
                 alertDialog.show();

Use your alertDailog 's current focus not your activity

Actually there must be delay so use this code

  public static void hideSoftKeyboardDialogDismiss(final Activity activity) {
    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            activity.runOnUiThread(new Runnable() {

                @Override
                public void run() {
                 InputMethodManager inputMethodManager =  (InputMethodManager) activity
                  .getSystemService(Activity.INPUT_METHOD_SERVICE);
                 if (null != activity.getCurrentFocus()) {
                  inputMethodManager.hideSoftInputFromWindow(activity
                   .getCurrentFocus().getWindowToken(), 0);
                  }
                }
            });
        }
    }, 1);
}
