            }
            // set the cancel button
            if (negativeButtonText != null) {

                                }
                            });
                }
            } else {

            dialog.setContentView(layout);
            dialog.setCancelable(onclick);
            return dialog;
        }

加入:dialog.setCancelable(onclick);
使用时：

CustomDialog.Builder builder = new CustomDialog.Builder(this);
                              `   builder.setMessage("");
                                    builder.setPositiveButton("", new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int which) {
                                            dialog.dismiss();
                                            }
                                        }
                                    });

                builder.setNegativeButton("",
                                            new android.content.DialogInterface.OnClickListener() {
                                                public void onClick(DialogInterface dialog, int which) {
                                                    dialog.dismiss();           
                                                }
                                            });
               builder.create(false).show();
