I have a program that sends a broadcast Intent that needs an "extra" value.The value is declared as being of type Object[], though I know that the elements are always of type Integer or String.That's part of an API not under my control. What's the most concise and/or efficient way to do the equivalent of the putExtra call below?

I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?

As soon as I changed the array to a string-array, this works fine. Is this normal? I realize that I can (and will) just convert the string array values to an int, but it seems weird that I have to.
I am trying to move my code from Java to C, and I have encountered a problem while trying to find a function in C that can take an array of ints and create a bitmap from it for OpenGL. In Java, I used
bitmap = Bitmap.createBitmap( {int array name} , w, h, Config.RGB_565);
Is there a similar function that I can use in C, or a workaround that I could use?
Also, if it matters, I am programming for Android.
I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.
how to write integer array to textview,what i tried is

tv.setText(se);
I have an xml resource in res/values/integers.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<integer-array name="UserBases">
<item>2</item>
<item>8</item>
<item>10</item>
<item>16</item>
</integer-array>
</resources>
and ive tried several things to access it:
int[] bases = R.array.UserBases;
this just returns and int reference to UserBases not the array itself
int[] bases = Resources.getSystem().getIntArray(R.array.UserBases);
and this throws an exception back at me telling me the int reference R.array.UserBases points to nothing
what is the best way to access this array, push it into a nice base-type int[] and then possibly push any modifications back into the xml resource.
I've checked the android documentation but I haven't found anything terribly fruitful.
I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
I want to get an array of strings reading from arrays.xml file we add in android values/ folder. Could any one kindly give a solution for this. Otherwise I will have to input each these entries in strings.xml and take them to java code using getResources()getString()
View 2 Replies View RelatedI have defined a string array in the resource and access it using:

I have a string-array in my resource file that has a little over 1,000 items in it. When I go to launch the activity that calls an AutoCompleteTextView the app won't load this array it simply backs out of that activity and returns to the previous activity. If I delete a bunch of items in the array it begins to work. How can I make it hold all my items? Is there a max size associated with this?

Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope.
My code looks like this:

I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused

How can i make any string/integer factory configurable in android? Alert dialog displays a text which is directly picked from a (central repository) file. Now we change the text in this file and make a rom image (but DO NOT compile the whole code) and flash it on the phone. Now the alert dialog would display the new text. This is what we call central repository data retrieval in symbian. How is this achievable in Android?

Is there a possibility to refer to a string ressource in the arrays.xml?
I have tried: <string-array name="services"> <item>@strings/call</item> </string-array>

I have a spinner filled with an array defined as xml resource:
<string-array name="distances"> <item>item1</item> <item>item2</item> </string-array>
Whenever I close the application I save the selected string of the spinner in a database. E.g. I save "item1".
On application restart I now want to reload the spinner with the previous selection. Therefore I read "item1" from the db and now have to somehow lookup the position of it and there I am stuck. An additionalproblem is that the array might have changed from the time where the data was saved to the db.
I get a String data from Cursor, but I don't know how to convert it to Array. How can I do that?

I have a String Array Resource that has about 1000 drug names
<string-array name="index">
<item>Aspirin</item>
<item>Levitra</item>
....
</string-array>
I tried to load this string array into a String[] inside an activity. Using the same syntax provided by Google's java documentation found here.
Resources res = getResources();
String[] drugs = res.getStringArray(R.array.index);
It appears my string-array has too many records and its causing my App to crash (stack-overflow?) When I reduce the string-array resource to about 506 records, the app works again, but adding even 1 more element in the string-array would crash the app. What should I do? I want to code logic to filter and do other things to the list. I do not have a SQL db in the app so I can't do the processing in the DB. Is there a way to iterate through the string-array resource without loading it into a String []? I notice the resource is a pointer. Or is there an alternative data structure or approach that would work?
