I want to use preferences to show like a list & want to show buttons at the bottom of similar screen?
I'm trying to make a somewhat advanced settings Activity (one that has a RadioGroup in one of the cells). The layout xml file contains the following:
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?
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.
Change log states "Toggle widgets can be skinned".where is the option? I'm sure it's obvious, but I sure can't find it.

View 2 Replies View RelatedI'm new to Android application development and I'm currently experimenting with various UI ideas. In the image below, you can see a vertically scrolling list of horizontally scrolling galleries (and also textviews as you can see). I'm also doing some matrix and camera transformations which I will come to in a minute.
For the background of the list elements, I use green. Blue is the background of the galleries, and red is the background for the images. These are just for my benefit of learning.
The galleries being used are extended classes where I overrode the drawChild method to perform a canvas scale operation in order for the image closest to the center (width) to be larger than the others. The list view going vertically, I overrode the drawChild method and used the camera rotations from lack of depth dimension in the canvas functionality. The items in the list are scaled down and rotated relative to their position's proximity to the center (height).............
Is there a way to use ListAdapter in preferences screen ? or i must use only chekboxpreference, textpreferences, etc....

Cheersss, Armond
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.

View 3 Replies View RelatedI'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.

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.
View 3 Replies View RelatedI'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:
CODE:.................
In a preferences screen in my application which is build by extending the PreferenceActivity i need to change background on the window itself and on the PreferenceCategory. How i can do it via Themes/Styles ? Which attributes i need to define ?

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?
View 1 Replies View RelatedI'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?
CODE:.................
I want to know how we can use shared pref in different application.

View 2 Replies View RelatedI 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 know only primitives can be stored in the android preferences, but do arrays count? Can I store an array of, say, Strings or booleans in an android preference?
View 1 Replies View RelatedI 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?
I would like some of my preferences to have icons, like the Settings app. I guess one way of doing this would be to copy all the relevant code and resources from the Settings app, but it seems like overkill for a couple of icons.
View 2 Replies View Relatedwe 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?

I want to get a system preference value in a class, but I don't have the context there, because the class that calls it doesn't have the context either. I've found that for Resources one can use the static Resources.getSystem() function. Is there any similar way for getting system preferences without context?
My class isn't an activity nor service. It's a utility class. Could give more info if needed.
