收集的J2ME中访问手机文件的方法

1. 遍历手机的根目录

 

Enumeration enumer = FileSystemRegistry.listRoots();
             String root = null;
             while(enumer.hasMoreElements()){
                 root = (String)enumer.nextElement();
                 append(root+"\n");
             }

2. 访问指定路径的文件

FileConnection fconn = (FileConnection)Connector.open("file:///存储卡/dialer.txt",Connector.READ);
         if (fconn.exists()){
                 DataInputStream dataIn = fconn.openDataInputStream();
                 int fileSize = (int)fconn.fileSize();
                 byte[] data = new byte[fileSize];
                 dataIn.read(data,0,fileSize);
                 append(new String(data));
             }else
                 append("file:///存储卡/dialer.txt not exist!");
         fconn.close();
