Midlet 显示Text File,中文出现乱码..

mikeng

如题。以下是我的Code.当Text File 里有中文字就会出现乱码，请帮忙。

import java.io.*;
import javax.microedition.io.*;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class HttpTXT extends MIDlet implements CommandListener {
private Command exitCommand, loadCommand;
private Form mainForm;
private TextField tfItem;
private TextField tf;
public HttpTXT() {
  mainForm = new Form("Download and Display Text");
  tf = new TextField("Text URL", "http://127.0.0.1:8080/TEST.txt", 120,
    TextField.URL);
  tf.setLayout(Item.LAYOUT_NEWLINE_AFTER);
  tfItem = new TextField("Text", "", 500, TextField.ANY);
  tfItem.setPreferredSize(mainForm.getWidth(), 200);
  tfItem.setLayout(Item.LAYOUT_VEXPAND | Item.LAYOUT_2);
  mainForm.append(tf);
  mainForm.append(tfItem);
  exitCommand = new Command("Exit", Command.EXIT, 1);
  loadCommand = new Command("Dowload", Command.SCREEN, 1);
  mainForm.addCommand(exitCommand);
  mainForm.addCommand(loadCommand);
  mainForm.setCommandListener(this);
}
protected void startApp() throws MIDletStateChangeException {
  Display.getDisplay(this).setCurrent(mainForm);
}
protected void pauseApp() {
}
protected void destroyApp(boolean p1) {
}
public void commandAction(Command c, Displayable d) {
  if (c == exitCommand) {
   destroyApp(false);
   notifyDestroyed();
  } else if (c == loadCommand) {
   new DownLoadTXT(mainForm, tfItem, tf.getString());
  }
}
private class DownLoadTXT extends Thread {
  private String txtURL;
  private Form form;
  private TextField tfItem;
  public DownLoadTXT(Form f, TextField i, String url) {
   form = f;
   tfItem = i;
   txtURL = url;
   this.start();
  }
  public void run() {
   String str = null;
   try {
    str = getText(txtURL);
   } catch (Exception e) {
    System.out.println("Error " + e.getMessage());
   }
   form.setTicker(null);
   if (tfItem != null)
    tfItem.setString(str);
  }
  public String getText(String url) throws IOException, Exception {
   HttpConnection c = null;
   InputStream is = null;
   String str =null;
   try {
    c = (HttpConnection) Connector.open(url);
    int rc = c.getResponseCode();
    if (rc != HttpConnection.HTTP_OK) {
     throw new Exception(c.getResponseMessage());
    }
    is = c.openInputStream();
    int length = (int) c.getLength();
    if (length > 0) {
     byte servletData[] = new byte[length];
     is.read(servletData);
     str = new String(servletData);
    }

   } catch (IOException e) {
    System.out.println("error" + e.getMessage());
   } finally {
    if (is != null)
     is.close();
    if (c != null)
     c.close();
   }
   return str;
  } }}

除此之外，platformRequest("http://.../AutoUpdate.wml");如果里面有中文字也是出项乱码。我的wml file 如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml">

<wml>
<card>
<p>
  <anchor>
    This is the latest version。尝试
    <go href="http://.../abc.jar">
    </go>
  </anchor>
</p>
</card>
</wml>

试试 加 这个 进去 。。

兔仙人

header(″Content－type: text/vnd.wap.wml; charset=gb2312″);

或者试试这个 。。

谢谢你的回复。可是可以告诉我加在那里吗？

mikeng

wml 解决了。不过Text file的还是不可以.

兔仙人

JAVA 那边 ， 你 可以试试 ，找找 关于 INTERNATIONALIZATION 和 LOCALIZATION 的 资料
