Exception when try to setError() in an editText inside a Popup Window

Question

This is my code:

 if(textNomeGiocatore.getText().toString().equals("")){
                InputMethodManager imm = (InputMethodManager)getSystemService(
                        Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(textNomeGiocatore.getWindowToken(), 0);

                textNomeGiocatore.setError("Nome giocatore necessario");





            }

I have an error in the row :

 textNomeGiocatore.setError("Nome giocatore necessario");

this is the error :

 android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@426940a8 is not valid; is your activity running?

I try to post delayed the error message without resoult.

   if(textNomeGiocatore.getText().toString().equals("")) {
        InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        if (inputManager != null &&  getCurrentFocus() != null) {

Try calling edittext.requestFocus() before calling set error. – Kantesh May 26 '15 at 09:26
Don't solve the problem.. the problem is that can't put a popup over another popup, or something similar – Luke May 26 '15 at 09:42
Then instead of parent popup use Dialog or Dialog fragment. – Kantesh May 26 '15 at 09:45
I have to use Dialog instead of PopupWindow? – Luke May 26 '15 at 09:49
I have the same problem, but instead you use dialog, there are another way to get the same result as set error. You can make your own layout to show above/below the edittext. The layout can be just simpl textview with red color or more complex layout depends on your need – HendraWD Dec 15 '15 at 04:50
