如何从BasePreferenceActivity显示DialogFragment？

Question

我有一个扩展BasePreferenceActivity的SettingsPreferenceActivity，在该首选项列表中，我有一个名为Upgrade的项目。单击此升级项时，我需要显示一个DialogFragment，这是我的升级屏幕。这是我正在尝试使用的代码......

DialogFragment dialogFragment =
                            UpgradeDialogFragment.dialogWithEntry("leftMenuUpgrade");
                    dialogFragment.show(this.getSupportFragmentManager(), "purchase");

我收到错误消息“无法解析方法getSupportFragmentManager（）”。

我也尝试过使用getFragmentManager（），我也遇到了同样的问题。

如何从BasePreferenceActivity中显示此DIalogFragment？

旧开发人员使用此代码......

                    Intent data = new Intent();
                    data.putExtra(EXTRA_UPGRADE, true);
                    setResult(RESULT_OK, data);
                    finish();

但它不起作用。什么都没发生，所以我试图为客户解决这个问题。

完整活动......
