I've got a map of about 500 entries. Strings are all very short (less than 5 chars).Its read-only data I want to read once at app-startup. What's the best way to store this so that loading this data is fast?I've tried storing the data in a CSV in res/raw but this takes about 700ms to parse on my N1, so I'm hoping there's a faster way.

Dear all, I'm making a simple file decoder for Android 2.2 that needs to find the filename of the encoded file from a header. This filename should then be used as the filename for the decoded file (as you would expect).The filename is identified by the substring name=, so the actual name starts 5 places after that. The line is read by a BufferedReader and temporarily stored in currLine.For some reason I can't understand nor find on the web, Strings do not always seem to be Strings.Gives no output file, nor an IO exception. The string is parsed properly though: from the System.out debugging lines.
View 1 Replies View RelatedCurrently I'm using a HashMap to map the strings to int and the int values need to be frequently accessed. I'm looking for a better way to do this if possible with minimal object creation, and preferable being able to store the values as primitive ints without wrapping them with the Integer class. (Basically, the reverse of the SparseArray's int->object mapping.)

View 2 Replies View RelatedIs it possible to reference other strings inside of strings.xml ?
Something of the form...
(If it did exist, there would of course be problems of circular, infinite definitions, etc. to beware of).
I find it a waste of time that every time I need to enter a string that I have to go edit the strings.xml file manually. What I'd like to be able to do ideally is have Eclipse pop up a dialog box that lets me specify the name of the resource and the value for it. Then Eclipse would generate the code in strings.xml and paste the correct reference to the string at the cursor position.

Its clear that '+' doesn't work here but is there some other option to achieve such a string concatenation, so that one could define a bunch of string resources that have a common prefix?I realize of course that I could do such resource string concatenation at runtime but defining them statically in the resources would seem so much more elegant and simpler.

View 5 Replies View RelatedIn my XML values strings code, I have a string with some text that I want to have only a few of the words in color. I also want to have a new line for some of the text.
I can do things like: < b> my bold text < /b> and that works (leading space added for this post).
I try to tag the text with color but no color shows up and there are no errors.

View 4 Replies View RelatedI am trying to create a information based application, I have 92 subjects, for these subjects I have 92 map locations and maybe as much as 400 url links. Currently I have created a class for each map location and a class for each url link, but this would mean I would have in excess of 500 classes, so what I want to do is split the subjects in four catergories ie. listview of about 23 in four tabs which I have done and create a class that gets the url based on the selection the use makes and do the same for the map locations.Do I need to put these in a xml using the id method and how do you call individual entries, i.e. would I need 500 Android:id is there an easier way?

View 3 Replies View RelatedI'm trying to parse a web service response using SAXParser and get certain values, store them into an arraylist, then display them in a listview. Example XML being returned from web service:
<ArrayOfStrings>
<string>value</string>
<string>value</string>
<string>value</string>
</ArrayOfStrings>
Here is my SAXHandler class:
public class SAXHandler extends DefaultHandler {
private boolean outertag = false;
private boolean mytag = false;
ArrayList<String> alist;
public ArrayList<String> getList(){
return this.alist;
} @Override
public void startDocument() throws SAXException {

}else if (localName.equals("string")){ this.mytag=true;
} }
@Override
public void characters(char ch[], int start, int length) {

SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
SAXHandler SAXHandler = new SAXHandler();
xr.setContentHandler(SAXHandler);
xr.parse(new InputSource(url.openStream()));
ArrayList<String> stateList = SAXHandler.getList();
aa = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, stateList);
RESTlist.setAdapter(aa);
I keep getting an exception and I don't know why. Can anyone give me a hand?

View 2 Replies View RelatedI am supporting search in my app, I'd like to display a unique hint in the search box depending on what activity is being viewed.
To that end, I have a two different searchable.xml files in my xml folder:
CODE:..........
When I reference searchable.xml, everything works as expected. The second searchable xml file has the same contents as the first, but this does not work:
CODE:............
Pressing the search key does not display the search box. If I just reference the first searchable instead, it works fine:
CODE:.....................
Again, both have the same content. It looks like there is a dependency on the name "searchable.xml" within android?
If we're not allowed to have searchables named anything but searchable.xml, how do we specify different hint strings for different activities?
For example:
CODE:..............

I got the following error:

How can I write character & in the strings.xml?
I've just tracked down a weird bug in our app where SharedPreferences were failing between power cycles of the phone.
It turns out that one of the strings we were saving had an "&" in it. When I look at the xml that is being persisted I see that this is being encoded as && instead of just &
This means that when you come to read the settings back you don't get any values at all. Is this a known issue? I see lots of posts about preferences dissappearing, but nothing about this.
