Android : Dynamically Add Items To Preferences?
May 12, 2010
we have an XML file placed in the res/xml folder containing our preferences.
Is it possible at runtime to add new items to the preferences.
Example:
The user starts the app and the preferences consists of:
America
- New York - Los Angeles - Chicago
Where all the cities are CheckBoxPreferences.
Then the user performs some actions in the application and this triggers that two new cities are added to the preferences:
America
- New York - Los Angeles - Chicago - Seatlle - Washington
Anyone that know if it possible at all and how to do it?

Im using a custom listView with a Title and a Subtitle where you can read a brief explanation of the item.
For each item on the list, im displaying an alertDialog to select an option (different for each case). When the option is selected, i want to change the Subtitle for the option selected by the user.
This is what i tried:
CODE:.....................
For the first item on the list it works fine, when i select an option, the subtitle get replaced by that option, but when i make a selection in the alertDialogs of the other 2 items, the option selected replaces the subtitle of the first item!

I have an Absolute Layout with two buttons on top, a Text View of fixed size in the middle and List View as the rest of the Layout.
I want to use the top left button to add a list view item to the existing list and the top right button to remove the last item from the list. The List is layed out properly when the App starts, but as soon as any of the two buttons is pressed, the Activity Force Closes.
Here is the code:..................

I am using a PreferenceActivity to let the user set some values. I am feeding it the xml file with the defined preferences.
I have set all the android:defaultValue="" for them.
When I start my application, I need the preferences, or if they are not set yet manually, I want the default values:
CODE:.................
However, when android:defaultValue="true" I still get false. So, it looks like the defaultValues set in the XML are not used anywhere but when initializing the preferences-screen.
I don't want to hardcode the default values in the getBoolean() method. So, is there a way get the default-values with only defining these in 1 place?

My application is used on multiple platforms so it saves it preferences to a file (rather than to the standard Android SharedPreferences).
Is there any easy of reusing the PreferenceActivity to save preferences to a file or is it a case of creating a whole new activity to do the job? If the latter is the case is there a layout I can use that will make the activity look like the normal preferences screen? PreferenceActivity uses com.android.internal.R.layout.preference_list_content but this doesn't appear to be available to apps for reuse.

My android application has two kinds of preferences:
1) I have user preferences defined in res/xml/preferences.xml so that users can manage their preferences with a PreferenceActivity.
2) I'd like to define another file for global configuration preferences of my app.
What is the best way to manage my app config preferences? Should I create another XML file with config values or should I specify those config values in strings.xml? What is the best practice for managing config preferences?

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.
However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).
1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.
2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?
3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

I am attempting to add a simple preferences file in a new Android project (New -> Android XML File), but it doesn't appear to be working correctly.
There is no root element to choose from when I select the Preference type layout. If I press Finish, it doesn't do anything. See screenshot below.

I would like to give users a choice of starting one of three different activities by choosing from three mutually choices. And I would like to provide users these choices as Preferences. If I use CheckboxPreference, user can select more than choices. Something like "RadioGroupPreference" would be good but it is not available from SDK. Can mutually exclusive preferences be implemented? Pointers or suggestions are greater appreciated.

I'm trying to give an option to users to be able to change the theme to the light one. I can't find any command or anything for this. I know I can set this in the Manifest file but this is not what I'm looking for.

I'm having this problem with one of my apps where some people are reporting that their preferences are not being saved when they close and resume the app. The preferences theyre talking about happen to be actual Preferences (i.e. the built-in preferences manager for an activity). They say they're not doing anything special, just exiting the app and going back to it. Does anyone know why the prefs wouldn't be saved for only this select few people? I'm at a complete loss.

Is there a way to launch a dialog (say, the dialog I show to users the first time they launch the app) from a preferences entry? I don't see any examples doing this in the API Demos, nor have I seen it out in the wild. I do see a class called DialogPreference, but this doesn't seem to be what I want.

I'm having a hard time trying to understand how the preferences activity works. Right now I have an activity for my preferences using a XML layout that has this:
CODE:............
The thing is that everything I do in the preferences are saved. I can reboot the emulator and I can access the preferences. I want to know how can I access this key from another activity on my application.
This is my activity:

I downloaded launcherpro, and there is no application icon with the rest of my apps. I wanted to fix my screens and stuff, but I cannot find the preferences for the app. I cant even find the app on my phone. It changed my home screens from 7 to 3. Is there only a way to get to the preferences by purchasing LauncherProPlus?

I'm trying to remove a preference from the screen so it isn't visible if the user is using an SDK greater than 2.2. I've found several answers saying that getPreferenceScreen().removePreference(thePreference) will work, but I'm getting FALSE returned every time I try it. Am I using it in the wrong place?
Any clue from my code?

I have a user preference in my app, which gets ued by different activity. I would like to know the best way to utilize those preferences between different activities in my App.
I have this idea to create a shared preference object from the main activity and from there send intents to the different activities to take actions. would it work?.. or just keep calling getsharedpreferences() from every activity?

I've just created some preferences using the PreferenceScreen XML following the Earthquake example from Wrox's "Professional Android Development" book.
Using the emulator, how do I accept the preferences?
If I use the back button I return a Activity.RESULT_CANCELED. So which key returns the Activity.RESULT_OK code?

I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean:
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);
boolean autoreplyon = settings.getBoolean("autoreplyon", false);
However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class).

I am creating a simple Android widget with a typical usecase of having many instances of it running at once.
Using the stock preferencesmanager, it seems each instance of the widget shares the same preferences.
Is there any way to not have this happen?
