android - the specified child already has a parent

Question

I created the AlertDialog using the builder. It shows when we call the show() method. I have the cancel button in that dialog. I can cancel that dialog by clicking the cancel button. My problem is once I cancelled displaying the dialog, I can't show the dialog again. It throws an exception like:

09-09 12:25:06.441: ERROR/AndroidRuntime(2244): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Answer 1

Don't show the same dialog, create a new one.

This is happening because you are trying to re-use the dialog which was already created (Probably at onCreate)and used once. There is no issue in reusing a dialog but as in the question the the specified child (the view) already has a parent (the dialog).You could either continue by removing the parent or you can create a new parent like :-

alertDialog=new AlertDialog(Context);
alertDialog.setView(yourView);
alertDialog.show();
