Question

  final Dialog dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.dialog_create_group);
        dialog.show();

从活动中打开对话框时运行正常。但是当我尝试从导航抽屉打开对话框时，我收到了这个例外：

Unable to add window -- token null is not for an application

我该如何解决？

            dialog.show();
