问题 I used the XML syntax to create a PreferenceActivity with a PreferenceScreen . I added an EditTextPreference and noticed that this renders as a dialog. Is there a way to make the EditText in-place i.e., the text field is displayed right in the PreferenceScreen instead of popping up as a dialog? 回答1: In case anyone comes across the same problem, this cannot be accomplished with the built-in Preference classes, but you can subclass Preference , and override getView() to return a ViewGroup

问题 I have a settings PreferenceFragment that allows the user to select a theme. The user can select a dark or light theme.

However the theme is not applied correctly, Switching from Holo.Light to Holo.Dark changes the background colour, action bar etc but does not change the text resulting in faded, hard to read

问题 I was just guessing how to access the DefaultSharedPreferences (set in a PreferenceActivity) from an application in a BroadcastReceiver, knowing that onReceive method comes with Context and Intent? Best regards, 回答1: In the BroadcastReceiver: PreferenceManager.getDefaultSharedPreferences(context) 回答2: Looking at the source of it, we can see getDefaultSharedPreferences actually uses getSharedPreferences. So we can use getSharedPreferences the same we getDefaultSharedPreferences uses it. In
