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?

View 3 Replies View RelatedI 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?
Is is possible to specify data in xml resource file and initialize ArrayList from it? I am looking for a way to use the ArrayList with a SimpleAdapter to bind to a ListView. I am wondering if there is a way to specify my data in xml resource file and init ArrayList from it.
View 6 Replies View RelatedI 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 have a string array and was trying to style certain parts of the text with tags like <b>, <i>, ... but it doesn't work.
The array looks like this:
CODE:................
The text is displayed in the textview like this: tTitel.setText(Html.fromHtml(Text[ii]));
I tried it without Html.fromHtml too but this had no effect. The styling tags do work if i use them directly in the code, like: tTitel.setText(Html.fromHtml("blabla<b>blabla</b>");
How to style the text in an array?
I have a custom Dialog that contains only a TextView to display some text in my application. The documentation lists that only the b, i, u, tt, big, small, sup, sub, and strike tags are supported. I really need to add some newlines for readability. Do I need to change to a more complicated layout, or is there some way to encode newlines in the resource? I tried adding br tags.
View 1 Replies View RelatedI am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:

However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.
I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.
I have a text file added as a raw resource. The text file contains text like:

I am using this following code which creates a ListView with text and an icon but the problem that I have which the following I want the array to be dynamic instead of static so my list gets created dynamically not statistically. My ultimate goal is to retrieve specific strings from my Db and to display it then on the Listview where every string would be in each row.

View 2 Replies View RelatedI have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?
I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database. The problem is using global variables in the widget provider. I need to hold the index of the value they are currently on in order to pass it to the intents which are created when the left or right buttons are created. The variable is always returned as zero though.

I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?

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.

Using XmlPullParser, on the START_TAG, I can use:

I have defined a string array in the resource and access it using:
