Android :: Preference Activity / Multiple Preferences

Nov 4, 2010

Is it possible to use the PreferenceActivity and PreferenceScreen to manage multiple instances of preferences fro a single app? It seems that they store preferences as "default" preferences only. I would like to use a PreferenceScreen as my configure activity for an AppWidget, but I need to be able to store distinct preferences for each widget.

Android :: Get Shared Preferences From A Preference Activity In Android?

Apr 10, 2010

I am using a PreferenceActivity to show some settings for my application.I am inflating the settings via a xml file so that my onCreate (and complete class methods).These preferences will automatically save to SharedPreferences as the user interacts with them. To retrieve an instance of SharedPreferences that the preference hierarchy in this activity will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this activity.

Is it possible to have multiple Shared Preferences per app? If you create a PreferenceActivity, the values by default are persisted to /data/data/[PACKAGE_NAME]/shared_prefs/[PACKAGE_NAME]_
preferences.xml

Is there a way to have multiple such files and which one to use for a given PreferenceActivity?

Android :: Shared Preference Listener Being Called Multiple Times When I Change A Pref

May 31, 2010

I've written an app with 3 tabs. Each tab has the same list view with different data sources. I have setup SharedPreferences in the tabhost activity, but I put my onSharedPreferenceChangeListener method in my listactivity. When I change a preference, my listener gets called and it updates my database. This is all working. However, if I change the data in tab 1, it calls my listener once. If I change the data for tab 2 it calls it twice and if I change the data in tab 3 it calls it three times. Any idea why it works this way? I guess I could setup my shared prefs in my listactivity and that might avoid the issue, but I'm curious why my listener is called multiple times if it's in a different tab.

Android :: Mangled Preference Activity

Sep 24, 2009

I have pretty unassuming preferences screen based on Preference Activity. (You can see it in DroidIn app) I'm having some problems with it that I think have to do with redrawing the screen after updates. Here are the symptoms: 1. OnPreferenceChangeListener#onPreferenceChange if I change summary of the preference by doing Preference#setSummary the new value is painted over the old one creating unsightly effect 2. My preferences screen is large enough that user has to scroll. While scrolling, the whole screen get all messed up, again it looks like view is redrawn (when scrolled) without erasing the background first.

Android :: Leaked Window In Preference Activity

Jan 30, 2009

I've created a set of preference screens building on the tuts on androidguys. My preference XML contains nested PreferenceScreens. The below doesn't occur in the root screen, only once clicking to a child PreferenceScreen. Once in that PreferenceScreen, even before selecting an EditPreference, if I change orientation (i.e. flick the G1 keyboard out) I get an error: 01-30 09:33:54.080: ERROR/WindowManager(1261): android.view.WindowLeaked: that was originally added here.I have previously overcome this in other activities by utilising the onPause etc methods with custom dialogs I use. How can I prevent this in the PreferenceActivity? What am I missing?

Android :: Preference Activity And Theme Not Applying

Apr 11, 2010

I have a problem in the Preferences Activity, in the main preferences the theme shows ok, but if I get to a sub preference, the theme gets messy, it is not white as it should, it is all dark, and the font is black so you can't see much, and when I start clicking on any items they will get sometimes white as they should but revert to black soon after. This is only happens on 2.1, in both the real device and emulator. Tested on the emulator running 1.6 and it was working correctly.

Android :: Preference Change Notifying Main Activity

Nov 13, 2009

I think I've missed something in how Android is supposed to work! I have the main Activity with a menu option that opens the preferences screen. What I need is a way for any changes that were made to be communicated back to the main Activity as soon as the preference is activated. At the moment the only way I could get it working is by using the intent data that gets sent back when the prefs activity closes but this isn't really enough. The reason why it needs to be instantaneous is that one of the preferences is a 'Clear cache' button, so I would like the data to be deleted when the user requests it and no later!

Android :: Save Configuration Value As Integer In Preference Activity?

Sep 16, 2010

Is there a way how I can tell the Preference Activity that value should be saved as integer? So far my all values are saved as strings... I can limit input to integers via XML easy:

<EditTextPreference android:key="SomeKey" android:numeric="integer" />

but it is still saved as string and later trying to getInt("SomeKey") on preferences object I always get java.lang.ClassCastException: java.lang.String.

Is there a way that EditTextPreference value would be saved not as string? Or maybe I should use some other type of Preference for numeric input?

Android :: Accessing Shared Preferences From Different Activity

Oct 19, 2010

When you establish a shared preference such as below.

public static final String PREFS_HI = "MyPrefsFile";

Can you access it from other activities just like you would normally do?

SharedPreferences settings = getSharedPreferences(PREFS_HI, 0);

Or is there something unique that you must do to access the preferences?

I encounter a problem with a ProgressDialog in a PreferencesActivity in my application.What I want to do is pop up a ProgressDialog after the user has changed his username or password during the check on the remote server. In the onSharedPreferenceChanged() I call the ProgressDialog.show() method. Sometimes it works fine, sometimes not at all.

Android :: Pros - Cons Of Multiple Activities In An App Vs One Activity - Multiple Views

Aug 16, 2010

Are there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.

I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.

What advantages of multiple activities am I missing?

Android :: Number Preferences In Activity - Game Of Life Program

Jul 8, 2010

What I want to do is I am working on a game of life program. I want to take the time delay and make it a preference, but I want to make it available for people to type in a specific time. The number can be in miliseconds or seconds. However I'm a little stuck on how to proceed, I haven't been able to find a simple preference that already handles this, but there might be one. Is there an easy way to make this preference and confirm that the entered data is an integer or afloat?

Android :: Preferences - How To Load The Default Values When User Hasnt Used Preferences-screen

Apr 22, 2010

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?

Android :: How To Clear Activity Stack If Using Same Activity Multiple Times?

Mar 3, 2010

So I have an app with Activity A. The layout on the activity is dynamic genearted. So it's possible that on Activity A a user hits a button that goes to "A" and the new page looks different, then a user clicks another button to go to "A" again. Now I have 2 Activities in the history stack. A, A, and currently on A. Is it possible that if a user clicks a button that the whole Activity stack is cleared in a scenario such as this?

Android : Save Preferences Other Than Shared Preferences?

Mar 19, 2010

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.

Android :: Activity With Multiple Repeating Backgrounds

May 13, 2010

I'm having trouble creating a layout with two backgrounds that tile in the x direction but not y.

I've mocked up what I'm trying to create here...

http://img153.imageshack.us/img153/6008/cnbackground.png

So the top section repeats horizontally, then there's a flat creen section in the middle in which I will center my content, then there's some horizontally repeating grass along the bottom.
