问题 I've created my own custom preference objects that extend Preference. I've only created them because there are no Preferences for these custom data types. Everything is working, but my custom preferences don't have the same appearance because they are missing the horizontal divider that the system preference objects have.

问题 I am re-using ListPreference for a setting which I store only in the database. How can I prevent it from storing/persisting any data to the preference file? 回答1: Subclass it, override shouldPersist() to return false. 回答2: I've not done it myself, but have you looked into overriding onDialogClosed() ? 来源： https://stackoverflow.com/questions/2488830/how-to-make-a-preference-not-save-to-sharedpreferences

问题 I am trying to figure out why the layout of my Preference menu is displayed in a false way on 10' tablets when using it in landscape mode. It looks like the lines that are to the right of the Checkboxes are actually to the left of them.
