Long press EditText crash: Unable to add window

Question

I am trying to do a long click in an EditText, but when I do a long Click, I receive the error below. I would like to be able to do a long click to get the Copy/Paste/Select All context popup so that the user can paste text into the box.

Fatal Exception: android.view.WindowManager$BadTokenException: Unable to add window -- token android.view.ViewRootImpl$W@799bfc6 is not valid; is your activity running?

The EditText is in a ScrollView in a PopupWindow. So when the error occurs, I am currently active on an Activity with the PopupWindow open and I do a Long Click within the EditText that is contained on the PopupWindow.

Answer 1

According to me, the reason that you're getting this error is that the outer_layout's onClickListener gets fired along with the onLongClickListener of your editText. And, since popupWindow.dismiss is called inside the click listener of your outer_layout, the popup window gets dismissed before your editText's long click listener code can run, thus causing the error.

The simplest solution to this would be to return true for your onLongClick method :-

editText.setOnLongClickListener(new View.OnLongClickListener() {
                @Override
                public boolean onLongClick(View v) {

                    //ADD HERE ABOUT CUT COPY PASTE
                    // TODO Auto-generated method stub
                    return true;
                }
            });

By doing so, you will consume the given long click, and it won't fire up any other unwanted listeners.

onLongClick() - This returns a boolean to indicate whether you have consumed the event and it should not be carried further. That is, return true to indicate that you have handled the event and it should stop here; return false if you have not handled it and/or the event should continue to any other on-click listeners.
