on implementing a multi-select (check boxes) ListPreference on Android? Would I have to extend the ListPreference? Is there any classes already documented to do this?

View 3 Replies View RelatedI have a ListPreference with the entries and entryValues correctly set. When I go in the prefernces activity and change the value it successfully works (I added a Toast to output the value after changing the option to test). But when I do the following to compare it, it always executes the else statment when I change it everytime, even like above when I changed the ListPreference and the value was "bluesky" it still failed to execute the correct if statement. Here's the code I use to check the value of the ListPreference in the onResume():
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this)
String backgroundPref = prefs.getString("backgroundPref", "");
if(backgroundPref == "bluesky"){
mainLayout.setBackgroundResource(R.drawable.bluesky);
Toast.makeText(getBaseContext(), "Blue Sky", Toast.LENGTH_SHORT).show();
}else if(backgroundPref == "sky"){
mainLayout.setBackgroundResource(R.drawable.sky);
Toast.makeText(getBaseContext(), "Sky", Toast.LENGTH_SHORT).show();
}else{
mainLayout.setBackgroundResource(R.drawable.sunsetscene);
Toast.makeText(getBaseContext(), "Sunset Scene", Toast.LENGTH_SHORT).show();
}
The Toasts are there so I can double check which statement gets executed, and it always seems to be the else one. Am I having a bad day and getting something wrong?

View 1 Replies View RelatedI've written an APP the uses has a small SQL lite DB and using a cursor adapter I can retrieve the records and populate a list view with them. from there I can get the Id of a selected item and delete it from the DB which works great. the issue I have is that as the DB grows deleting one row at a time would be slow and frustrating so I wanted to know if there was any way to allow multiple selections possibly with check boxes or by even changing the text color of the items selected so that I can retreiving their relative ID's.
I have read some posts that talk about custom cursor adapters but I am not sure how to adapt them to my code.

I'm displaying the contacts in a Multi-select "Ok, Cancel" dialog box. I've implemented Filterable for the adapter that displays the contacts in the dialog. The problem is, once i try and select(check) a contact while i'm using a type ahead, the check box in that particular position is checked and not the contact.
The initial screen goes like
After type-ahead,
When I hit backspace, the screen appears as,

I have the latest Play-Store installed on my phone (which is a Sony Ericsson XPERIA x10) and although I have read in a bunch of forums that in the latest version you can go to "ALL" applications' section and delete the history of your downloaded applications by multi-selecting the desired apps (long press), it doesn't seem to be happening on mine.

Note I said gmail app not gmail webbrowser. Or is there a better gmail app with push email vs imap or pop?
A friend of mine was asking my why the new version of K-9 Mail doesn't have multi-select anymore. I was confused as mine does. So, with some investigating we found that K-9 Mail Beta is no long a beta version. It's just "K-9 Mail", version 2.000. And it isn't as robust as the beat version. What's up with that?
Better backup your old beta version if you like it. And don't update to the new until they get that mess straightened out.
When using a PreferenceActivity to do preferences, the PreferenceScreen can contain a ListPreference. A ListPreference has an array of keys and an array of values. But the PreferenceActivity only writes the values to SharedPreferences. How do I get the key of the item selected from the list? I would have thought this is pretty fundamental, especially if you want to translate your app.
View 13 Replies View RelatedI'm using listpreference in my android app and getting my key values and all is well and works good (now that you guys have helped me) BUT - when my listpreference menus popup, they only contain a cancel button. Let's say the user is choosing between red, blue, and green. When the listpreference dialog first pops-up, the dialog only shows a cancel button. Because of that, the dialog disappears as soon as the user selects their choice. I would like it so that when the user chooses their setting, they see the radio button get highlighted and then they go ahead and click the ok button...but I don't have an ok button and can't figure out why.

int count = items.size();
CharSequence[] entries = new CharSequence[count];
CharSequence[] entryValues = new CharSequence[count];
for (int i = 0; i < count; i++) {

I'm trying to implement a Select All menu item for a ListView in a ListViewActivity. The relevant parts of my ListViewActivity: public class MyListViewActivity extends ListActivity browsed around stackoverflow.com and the google; the above is something that should work. But it isn't. setSelection(i) appears to be the method I want to call on ListView but it's not working as advertised. What am I doing wrong? Is this even possible on Android in code?
View 2 Replies View RelatedI want to put a ListPreference in my preference screen. But all the examples I have found in Internet the content are loaded out of a xml and I need that de options in the ListPreference are dynamic and not previously defined (in a xml).
I have mi preferences.xml in the folder xml/ of my project;

I have an XML preferences screen which is handled by addPreferencesFromResource. On it, there is a ListPreference, for which I want the summary to contain the current value of that preference. I think this would be a common requirement, as otherwise you could not see the present value of the preference without expending a click. I read that the summary field supports resource references, and I see that I can refer to preferences as android:summary="@+preference/prefname" in my ListPreference. Clearly this is why resource references would be supported in this field. However, when I try this, instead of the present value of prefname, the text "false" appears as the summary. Does anybody know how to display a current value without taking the seemingly ridiculous step of rewriting the entire (large) preference screen in Java?

This is my first Android app (which is a soft keyboard, with dvorak layout) and so far it has gone pretty smoothly (either because or despite working from the sample code). I've had some problems (with special/swedish characters) that I've managed to take care of, but this problem I can't figure out how to solve..
But when I click the list item to edit it, i get an empty dialog (Title and button is shown right and with the text I set in the xml- file, but no list, screenshot: http://i49.tinypic.com/2501p55.png ). I can't see any problem with the program code (which isn't many lines..) or the xml (the arrays are generated by the Android utils in Eclipse and the preferences is a mix of auto and manual). You can see both Java code and XML here: http://pastebin.com/m4c52c3a2 (titles etc in Swedish..) (I've also tried a EditTextPreference item, which seemed to work fine..) I have also looked at the log/output using adb, and can't see any problems there either, so I have no idea onto how to solve this.
I am resuing ListPreference for a setting which I store in the database. I do not want it stored in the preference file. How can I reuse ListPreference in such way that it does NOT save to SharedPreference file?
View 2 Replies View RelatedI have a settings menu that pops up and in it is a listpreference type menu. It is associated with a settings.xml file where there are 'array-strings' within it. It all works good but I don't know how to retrieve the users preference. As an example, let's say the user picks a color (red, green, or blue). The list that I've made within my 'array-strings' contain the text red, green, and blue. Within my code, I would like to do something if the user has choosen red, something else if they choose blue, etc., etc. Would I use a 'case' statement or an 'if' statement? And most importantly, how would I retrieve the users preference - the key? (am I checking for a boolean?)

I want to have an element in my preference menu that does the following: Show a list of options. Many are selectable Maximum amount of options to be chosen 2. Possibilities I thought of: Doing a separated PreferenceScreen and showing options as checkBoxes but I don't know where to place the logic of max 2 options. Extending DialogPreference and doing it by hand.
View 2 Replies View RelatedI am trying to put together a modal box with a scrollable list of checkable items and an OK and Cancel button at the bottom for the user to select filters from. It seems the simplest way to do things like this in Android is to reuse API components (widgets, layouts, etc) and the closest one I can find to this looks to be the ListPreference, which basically does exactly what I want (I can even work with storing the data in SharedPreferences). The problem is that I'm not launching this modal box from a PreferenceActivity, but rather will be launching it from either of two activities: a ListActivity and a MapActivity.
