I want to create a ArrayAdapter for one spinner. So each element contain one string (which will be displayed in the spinner/list) and one value (e.g. an ID). How I can easily store a second value beside each string without implementing a new Adapter class?

I've overriden runQueryOnBackgroundThread and done what I've needed to do for the corrent query to be excuted with a given constraint. My current challenge is figuring out how to actually pass in the constraint. I've got an ActivityList which I'd like to filter on a stored preference. I'm thinking I will need to perform a filter during onStart such that the most recent preference changes are picked up. All that is in place, just not clicking on how I'd actually cause the filter to happen!
View 2 Replies View RelatedI'm implementing my own sync adapter and everything works great. A strange i'm having is that after the sync is over, the Android still shows the sync icon (the one with the rounded arrow) in the account activity, and that someone (i guess its the account manager) repeatedly calls the sync again and again, every 30 to 60 seconds. Now i tried all sort of things to test this issue and i have discovered something strange. In my code, i do resolver.applyBatch every 50 new rows. (each new contact i sync has about 5 rows). If i remove the applyBatch (which means i retrieve the data from the next, sort it and prepare it, but never "commit" it) - the problem goes away. The icon disappear and the account manager never calls it again on its own (I'm using Android 2.1). I must also state that no exception is being thrown in any of the cases and that all the methods finish gracefully.

View 2 Replies View RelatedI have been playing around with a LazyList code sample which is pretty neat for displaying images in a safe and non-memory-hogging way. It uses a very simple mechanism of displaying images based on a list that exists within the class file.
Example:
CODE:...........
I am trying to load these values from an index file that is downloaded to the SD card, and then loaded from it. Here is the code that loads the index file and simply displays it as a Toast message (this works fine).
PULL FILE FROM SD CARD
CODE:.........
What I am struggling with is how to take this string that is being loaded from the SD card and pass it into the list adapter.
The code presently looks like this:
CODE:................
I am trying to reload or refresh that same adapter using the values I pulled from the SD card file, presently called "readString".
Can anyone give me some pointers? I am leaving out the code that I created that doesn't work ... because I don't think I am handling this at all correctly. Also - go easy on my, I am a complete newbie to all of this. :-)
Here is my what I am trying to do. Simply copy and paste the working code where I want it. I know it's not that simple, but I am having a hard time reconstructing it properly. Here is my edited code ...

I am trying to set the class for an intent to the address listed in a string value, so that I can launch a given activity. The string is composed dynamically during runtime.
Is there anyway to make something like the code below run...
What I did was create two .java files. One that can compile and run on a 1.5 phone (SDK3) and then one that works on 2.0(SDK5) So for this example i'll call the 1.5 file ExampleOld and the new one Example. I was wondering if i just made activity like this if it would work sort of like a "portal" and pick the activity to load depending on the SDK so there is no crash or compile errors. Are there any changes I should make to my code? Maybe anyone out there that's had to do this before.

I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);
The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};
What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:
private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.
I'm a bit new to Java, Android, and development in general.
I have code which has one activity which passes information to a second activity.
I can use this information to pass to a third activity with additional information from the result of the second activity.
I want to use gestures as a method of going back to a previous activity, but if I go back from the third to the second activity I need the information initially passed from the first to the second activity to still be present.
i.e.
First Acticity
what is Y?
answer y = 5
Second activity
User said Y = 5
what is X?
Third Activity
User said Y = 5
X = 6
Go back to Second activity but maintain the input of
User said Y = 5.
To do this I have used a bundle to pass the information between activities, but I can only access the info in the bundle from within a method within the class started by the intent.
The gesture controls are within another class, so I cannot access the bundle information from within this class as the getIntent command produces a not defined error.
What I need to do is to be able to pass the information from the bundle from the first activity to the gesture class so that I can pass it back when I go back using the gestures.
So I ran into a problem today while working on my Android program. I have a class that turns that an XML string into a Java object (third party) and it works fine in as a regular java project but on Android I get this weird error:

How do I access to the string 'Icon List' given IconListActivity.class?
Is it possible to store strings values in multiple files? Eg, strings.xml, strings1.xml, strings2.xml etc.
I do not mean localized versions of the same file - those multiple files should contain different string ids in the same language, so in code they would be refered like: R.strings1.my_string_1 R.strings1.my_string_2 R.strings2.my_string_3 etc. So, "strings1", "strings2", "strings3" would be a kind of namespace for them.
Or, another way is to have multiple R classes inside one project, which would deal with different stringsXXX.xml files.
Like, currently we can refer to "my.name.space.R" and to "android.R" at the same time, so is it possible to have: android.R my.name.space1.R my.name.space2.R etc
At the same time inside single project?

View 4 Replies View RelatedIn Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

View 4 Replies View RelatedI'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.
