Introduction
By default all the maps in the Map API for Java ME will display in English. The API is however able to support a variety of other languages. The language used to display labels on the map is set in the ApplicationContext, and this should be done prior to displaying the map itself. The setDefaultLanguage() method takes a three letter MARC Code. If an unsupported language is requested, the map will display in English by default.
Invalid language.
You need to specify a language like this: <source lang="html4strict">...</source>
Supported languages for syntax highlighting:
4cs, 6502acme, 6502kickass, 6502tasm, 68000devpac, abap, actionscript, actionscript3, ada, algol68, apache, applescript, apt_sources, asm, asp, autoconf, autohotkey, autoit, avisynth, awk, bascomavr, bash, basic4gl, bf, bibtex, blitzbasic, bnf, boo, c, c_loadrunner, c_mac, caddcl, cadlisp, cfdg, cfm, chaiscript, cil, clojure, cmake, cobol, coffeescript, cpp, cpp-qt, csharp, css, cuesheet, d, dcs, delphi, diff, div, dos, dot, e, ecmascript, eiffel, email, epc, erlang, euphoria, f1, falcon, fo, fortran, freebasic, fsharp, gambas, gdb, genero, genie, gettext, glsl, gml, gnuplot, go, groovy, gwbasic, haskell, hicest, hq9plus, html4strict, html5, icon, idl, ini, inno, intercal, io, j, java, java5, javascript, jquery, kixtart, klonec, klonecpp, latex, lb, lisp, llvm, locobasic, logtalk, lolcode, lotusformulas, lotusscript, lscript, lsl2, lua, m68k, magiksf, make, mapbasic, matlab, mirc, mmix, modula2, modula3, mpasm, mxml, mysql, newlisp, nsis, oberon2, objc, objeck, ocaml, ocaml-brief, oobas, oracle11, oracle8, oxygene, oz, pascal, pcre, per, perl, perl6, pf, php, php-brief, pic16, pike, pixelbender, pli, plsql, postgresql, povray, powerbuilder, powershell, proftpd, progress, prolog, properties, providex, purebasic, pycon, python, q, qbasic, rails, rebol, reg, robots, rpmspec, rsplus, ruby, sas, scala, scheme, scilab, sdlbasic, smalltalk, smarty, sql, systemverilog, tcl, teraterm, text, thinbasic, tsql, typoscript, unicon, uscript, vala, vb, vbnet, verilog, vhdl, vim, visualfoxpro, visualprolog, whitespace, whois, winbatch, xbasic, xml, xorg_conf, xpp, yaml, z80, zxbasic
System.getProperty("microedition.locale");This will retrieve a 2 letter MARC Code, which can be mapped onto a 3 letter MARC code using a simple switch statement.Examples of usable MARC codes include:
- ARA Arabic
- CHI Chinese
- GER German
- ENG English
- FRE French
- ITA Italian
- RUS Russian
- SPA Spanish
Implementation
This is a simple example of a minimal map which will display in one of eight random languages.
public class MapLanguageMIDlet extends MIDlet {
protected void startApp() throws MIDletStateChangeException {
// Please initialise the appId and token first
ApplicationContext ctx = ApplicationContext.getInstance();
ctx.setAppID("MyAppId");
ctx.setToken("MyToken");
Display display = Display.getDisplay(this);
MapLanguageDemo minimalMap = new MapLanguageDemo(display, this);
display.setCurrent(minimalMap);
}
protected void destroyApp(boolean unconditional) throws MIDletStateChangeException {}
protected void pauseApp() {}
}
public class MapLanguageDemo extends MapCanvas implements CommandListener {
private final Command EXIT = new Command("Exit", Command.EXIT, 1);
private final static String[] MARC_CODES = {"ARA", "CHI", "GER", "ENG",
"FRE", "ITA", "RUS", "SPA"
};
private final static String[] LANGUAGES = {"Arabic", "Chinese", "German", "English",
"French", "Italian", "Russian", "Spanish"
};
protected MIDlet midlet;
public MapLanguageDemo(Display display, MIDlet midlet) {
super(display);
this.midlet = midlet;
init();
}
private void init() {
addCommand(EXIT);
Random r = new Random();
int i = r.nextInt(LANGUAGES.length);
ApplicationContext.getInstance().setDefaultLanguage(MARC_CODES[i]);
setTitle(LANGUAGES[i]);
setCommandListener(this);
// Set map over Europe.
map.setState(
new MapDisplayState(new GeoCoordinate(53.1, 13.1, 0), 4));
}
public void commandAction(final Command c, Displayable d) {
if (c == EXIT) {
midlet.notifyDestroyed();
}
}
public void onMapUpdateError(String description, Throwable detail, boolean critical) {
Alert alertView = new Alert("Map error: ", detail.getMessage(), null, AlertType.ERROR);
display.setCurrent(alertView);
}
public void onMapContentComplete() {
}
}
