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.

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.
Is there a way to change the HTC Icons like camera, photos to the stock Android Icons?
View 5 Replies View RelatedMy 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 can access the preferences and add and change them. How can I view the entire file that stores the keys and values for sharedpreferences in my app. I have changed, added and removed some keys from my code and would like to see the effect on the preference file.
View 1 Replies View RelatedIn an Android utility class, 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.
I can create a new preferences file by calling Context.getSharedPreferences(String name, int mode), putting some values in the returned preferences' editor, and committing. However, I don't see an interface in the API to remove the created file when I no longer need it. I've tried Context.deleteFile(String name), passing in the same name argument from above, but that returns false, indicating the file wasn't actually deleted. I'm using MODE_PRIVATE, if that makes a difference. Browsing the source for context's implementation of the editor doesn't reveal any clues either, as far as I can tell. Any ideas? The background here is that I'm allowing my users to save copies of their "current" preferences so that they can restore previously saved settings. When they don't want those settings anymore, I want to remove the saved preferences file so it doesn't take up space. At the moment the best I can do is an edit().clear().commit on the file, which I believe will remove most of the contents. Not as good as delete, though.

I want to create a "row-based" prefs dialog, like you see in most standard apps. You know, black background, fading-line separators, bigger/bold label text for each entry, smaller description text, perhaps a checkbox/down arrow.
Is there a standard object in the Android API for this? If not, how do people usually create these?
I save preferences in one activities but not able to get saved preferences in other activity. I can access saved preferences in the same activity but not in other one.
It is not giving me any error but always gibing null values in second activity.code...
From what I can incur out of the SharedPreferences documentation, I can update a preference, add one or clear all preference values in a shared preference file.
But I want to completely clear everything inside a shared preference file, not just the values, but the preferences they refer to as well.
I think that it would be too complex to open a database. Does using shared preferences make my app's data size become big. Is there a temporary storage place for my data or should I delete the data in the shared preferences for that widget.
View 1 Replies View RelatedSay my app has a widget and I use a configuration screen to do initial app widget setup and set a few preferences.
I want the user to be able to change those settings by simply going into my app's settings screen and clicking an intent preference to open up the same options the user was given when the app was created.
Can I use the same activity as the configuration activity? Will I have to handle it differently? How does the existing widget get updated with the new settings?
How can I get this to work?
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.
If I store some user settings and information in shared preferences in my android apps, and then I update the app in the Market, will those settings be erased when the app updates?

Because I get to edit files, but I am looking for a long time without finding how to put ALL the icons on the left, and keep only the icons on the right as in the picture.
I notice that the home screen is customizable but not the four applications on the bottom, the call, email, browser and applications. How would I change those icons with different icons? Mainly the email and browser. How do I turn off or at least severly limit the data that goes to and from my phone. I do not have wireless and am just a bit paranoid about going over my data limit. I got the phone from work and this is my first smartphone so I am a bit nervous about anything I do on it.

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.
View 10 Replies View RelatedIs 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.
