I have a PreferenceScreen that is defined in XML that serves all the preferences for my application. This PreferenceScreen also has a child PreferenceScreen nested within it. My implementing class is called PreferencesActivity. I know I can open the main Preferences window via startActivity(new Intent(this, PreferencesActivity.class)); but how do I go about opening the child PreferenceScreen via an Intent?

View 3 Replies View RelatedI have a layout xml file with a linear layout. One of the children is again a ViewGroup Relative layout. In my java code i want to change the width of this child Viewgroup for my requirements. I tried this
ViewGroup childViewGroup = (LinearLayout)findViewById(childViewGroup);
LayoutParams l = childViewGroup.getLayoutParams();
l.width = 360;
childViewGroup .setLayoutParams(l);
I couldn't do this because findViewById(childViewGroup) doesn't fetch ViewGroups it does only for Views. Note: I cant define a whole new layout.xml for this minor requirement since it is huge layout file and might cause performance overhead. I wanted to just change the width of the child view group in my java activity code.
I have a PreferenceActivity defined in the manifest with android:theme="@android:style/Theme.Dialog. The theme works well with the first settings screen, but not with the child PreferenceScreen elements (if I have several screens in my preferences). The child screens have the default Theme applied in this case.If the theme is changed to Theme.Light or the default, it works well for all the screens(parent and children included)Is there a way to apply the theme to the children, or is this a BUG ?

View 1 Replies View RelatedI have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
I'm not sure whether I'm badly misusing InstructionCount or there is a bug, but let's assume the first one for now. The simplified situation is like that: I have a function (say, foo()) for which I want to track the number of instructions executed and the function itself calls another function (say, bar()), for which I also want to keep track of the number of instructions executed, something like: Code...

I have an ArrayAdapter where I inflate the stuffView. My thinking and understanding of other examples is it's not inflated (this nested stuffView) until I purposely inflate it. That all works fine but when I do the findViewById it returns null and thus I can't setText().

Can some kind soul point me in the right direction?

View 4 Replies View RelatedI have a TabActivity which contains an Activity. When the tab for the activity is selected, if I press the Menu button, onPrepareOptionsMenu is called in the parent TabActivity, but not on the activity for the tab which was selected. The options menu for the activity in the tab isn't shown unless I click inside the tab, then I get calls to both (which is what I want). Is there any way to 'focus' the activity in the tab when the tab is selected?
View 1 Replies View RelatedI am currently trying to implement a PreferenceActivity for my application that uses custom default values for its preferences instead of the defaults declared in the corresponding preference XML as the defaults are supposed to change dynamically based on certain conditions.However, when I modify the defaults via the Android API after loading the preferences through addPreferencesFromResource(R.xml.preferences); it already seems to be too late and the individual defaults set via Preference.setDefaultValue do not seem to be taken into consideration when rendering the UI.As I would like to avoid re-inventing the wheel I hope there is some possibility to achieve this using the standard Android preference API. Is there any way to trigger a re-evaluation of the values (and default values) associated with a PreferenceScreen hierarchy? I did not yet try whether creating the PreferenceScreen via APIs instead of loading from XML would help, so that could be an option.
View 3 Replies View RelatedI would like to have a Preferences activity that has icons like the system settings has had since Eclair. It uses a special Preference called IconPreferenceScreen.I can copy that into my project without problem, but I'd like the behavior of the PreferenceScreen instead of just the Preference Class. I could like to click on it to show its children Preferences. I thought it would be a easy to change to make IconPreferenceScreen extend PreferenceScreen instead of Preference, but PreferenceScreen is Final.Why on earth would google make PreferenceScreen a final class? Is there anyway to achieve what I would like to do, short of dividing up my Preference into several other Preferences that all receive intents (That's how the system settings works.)

The preferences are inflated from xml.I managed to create and read custom xml attributes for EditTextPreference, ListPreference and CheckBoxPreference by creating custom classes which inherit from the respective preference class.My problem is that I can't do this for the PreferenceScreen class, as it is a final class. So my question is: Is there any way I can read the custom attributes of a PreferenceScreen?

View 2 Replies View RelatedI've got a probleme with an exception, but I don't know why I get this exception.
The project is about implementing an AbstractAccountAuthenticator with an AbstractThreadedSyncAdapter to sync certain data on a server with a content provider.
I made everything and both adding accounts and syncing is running without any problems.
Now I've tried to add a Preference-Screen just like suggested in the android reference (search for AbstractAccountAuthenticator, it is explained there) via xml like this:
autenticator.xml:
CODE:..........
The Preference-Screen-xml looks like this:
CODE:.....................
The screen is promted how it should be, but and that is the problem: When I click on the PreferenceScreen with the intent it leads to a crash of the system (both in the emulator and my HTC-Desire).
Logcat says:

Here the part of the manifest, where the activity is defined:

I have my own custom Content Provider that loads a database which contains the settings information for my application.
I load the settings from the ContentProvider on the creation of my Settings activity.
My Settings activity is made up of a PreferenceScreen and Dialog based EditText's.
The following code shows how I use the preference screen and edit texts.
So as you can see from the first image this works and displays the menu with the information underneath.
The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog.
I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider.
what I'm trying to do?
CODE:......................
I have a PreferenceActivity with a bunch of (Sub)PreferenceScreens. Each such (Sub)PreferenceScreen represents an account and has the account-username as its title.
CODE:................
As the user enters sub-PreferenceScreen, and edits the account user-name, I want the outer PreferenceScreen to update it's PreferenceScreen-title for the account in question.
I've tried to add...
CODE:.............
But the accScreen.setTitle does not seem to take effect on the outer PreferenceScreen. I've note that calling onContentChanged(); actually makes it work, but I realize that this is probably not the preferred way of doing it.
I suspect I should call postInvalidate() on some view somewhere, but I really can't figure out on what view and when to do it.
