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

We went with a redesign to take away the popup and eliminate the bug that was there.

Answer 2

You may be calling your popup too early. In my example (gist here), I am executing the popup code from a button press. This is after onCreate() and the other key lifecycle methods run. With the example, everything works OK.

If, however, I try to instantiate the popup in onCreate(), I get a logcat error that states: "android.view.WindowManager$BadTokenException: Unable to add window" which is what you are seeing.

I believe that you are trying to instantiate your popup too soon. Start it later in the activity's life cycle and definitely after onCreate() executes. If you need to instantiate it pronto, you could attach the code to the UI message queue via a call to post(Runnable). (See here).

I am fairly certain that this is your issue. If this doesn't help, update your question with more information about how and when you instantiate the popup window.

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.

Answer 4

in your main Activity

private Content mContext;

public void onCreate(){
 mContext = this;
}

replace getBaseContext() with mContext

LayoutInflater layoutInflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);

or

  LayoutInflater layoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
