New Android developer here - I'm hoping this is simple.
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?

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.

How to create a custom dialog box in android?
Any example program?
I am looking for a way to create dynamic preferences where I don't need to hard code the preference key and I could have a variable number of preferences. Basically, my application will let the user create a multiple number of profiles and each of these profiles will save custom values for a fixed number of preferences. So this way, the user does not have to change the preferences every time he wants this app to run differently, he can just switch the profile. One way I think will work is by subclassing all the standard Preference classes and calling their setKey method with my custom preference key, containing the profile name, but this is ugly. So is there a cleaner and more standards compliant way to do this?
View 1 Replies View RelatedI would like to be able to close the editpreference dialog (as shown here http://twitpic.com/18ttdp) by pressing the 'Done' button on the keyboard. Currently, pressing 'Done' just dismisses the keyboard but leaves the dialog. In other parts of my application I use code similar to the following to intercept the 'Done' key press and execute actions in my activity:
text.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override public boolean onEditorAction(TextView v, int actionId, KeyEvent event)
if (actionId == EditorInfo.IME_ACTION_DONE) {
//do stuff here return true;
} return false;
} } );
However, I am unsure of how to do achieve this same effect in my preference activity or layout XML.
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?
I have a dialog with a list view in it and am wondering if there is a way in to create a dialog that appears like an activity? i.e. fullscreen and fix size? Is there is any style that can be applied to have this activity-like appearance?
View 6 Replies View RelatedI have an app that performs an asynchronous login as part of its startup sequence. This eventually displays a list of items.
A separate thread performs integrity checks on a database on the sdcard during the startup sequence. If something is unexpected, I do a sendBroadcast() that triggers a showDialog() on my base activity class. This asks the user on how to react to the unexpected event.
My problem is: this dialog disappears as soon as the startup sequence finishes and displays the list of items. Is it possible to make my dialog stay on top no matter what?
I've an application that you can show and close several Dialogs with:
showDialog(...)
removeDialog(...)
I play a little bit with the application and when there is no any Dialog on the screen, I press the menu button and I go to the main android screen.
After a while, I enter again into my application and sometimes, I get this RuntimeException:
CODE:...........
I have created a custom dialog class
CODE:............
Now my requirement is to create listview inside it. i know we can create textboxes,buttons,dropdown list inside it. but in order to create list view we should inherit our class from listActivity class. is it possible or not if yes then how to achieve this using any interface or what?

How can I create a dialog with each dialog item being a label and then a checkbox?
And when user click 'ok' to the dialog, I can tell in my code which on of the dialog item has been checked?
I am wondering how one would create a dialog box that only pops up when the app is first opened. For example, I have an Android app on the market. When I update it, I would like to implement a box that pops up that displays what has been updated in the app and will not pop up again until the app is updated again.
View 2 Replies View RelatedMy 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.

View 6 Replies View RelatedI want my menu item "info" to create a custom dialog. Yet i appear to to be having trouble:
This is in my main java file:
CODE:..............
I'm trying to create a basic AlertDialog using an activity with a theme of Theme.Dialog.What I want is for there to be a horizontal bar between the title and the message. However, the bar is not being resized correctly. Rather than being the width of the activity, the bar is the width of the message text. This means that if the activity is being expanded by the message, then the bar will fill the whole activity, so it looks correct. However, if the message width is less than the activity width, the bar only displays above the part of the activity with the text. I've tried every single combination of "fill_parent" and "wrap_content" that I can think of, and none of those work.I've also tried using RelativeLayout and placing the bar above the message text, but that also doesn't work. If I use the RelativeLayout approach and set the bar to fill_parent, it causes the activity to expand to fill the whole screen width, which is also undesirable. Ideally, I want the text placed, the activity width computed, and the bar resized to that width (without affecting it). Is there some way to flag a view to fill the parent view but not to affect its size?
View 1 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 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 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.
View 1 Replies View RelatedI 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.
