读取手机相册里的照片

[liangruifang]

急求读取手机相册里的照片程序（j2me）

[kongyanmin]

public void read(String url){
FileConnection fc = null;
InputStream in = null;
try{
fc = (FileConnection) Connector.open(url);
in = fc.openInputStream();
try{
ByteArrayOutputStream output = new ByteArrayOutputStream();
int ch;
while((ch = in.read()) != -1){
output.write(ch);
}
byte[] bytebuffer = output.toByteArray();
Image image = Image.createImage(bytebuffer, 0, bytebuffer.length);
form.append(image);
output.close();
}catch(IOException e){
e.printStackTrace();
}
}catch(IOException e){
e.printStackTrace();
}finally {
if(in != null){
try{
in.close();
}catch(IOException e){
e.printStackTrace();
}
}
if(fc != null){
try{
fc.close();
}catch(IOException e){
e.printStackTrace();
}
}
}
}

源码没有
建议去看JSR75 FileConnection

读取相册里面的图片首先要用到FileConnection
我刚用N95试了下，拍摄的相片存储在C:/Data/Images/200912/200912A0下，红色的部分可能不一样，一般存储在C:/Data/Images/下，你需要递归这个目录。
遍历目录的方法：

读取图片的方法：

  /**
     * 读取图片
     * @param path
     * @return
     */
    public byte[] readImage(String path){
        FileConnection fc = null;
        try{
            fc = (FileConnection)Connector.open(path,Connector.READ);
            InputStream is = fc.openInputStream();

            byte[] b = new byte[1024];
            int len = 0;
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            DataOutputStream dos = new DataOutputStream(baos);
            while((len = is.read(b)) != -1){
                dos.write(b, 0, len);
            }
            byte[] data = baos.toByteArray();
            return data;
        }catch(Exception ex){
            ex.printStackTrace();
        }
        return null;
    }

比如C:/Data/Images/ 文件夹下有一张me.jpg，调用的时候的path = "file:///c:/data/images/me.jpg";

    private Image loadImage(String address) {
        FileConnection fc;
        DataInputStream is;
        Image img = null;
        try {
            fc = (FileConnection) Connector.open(address,Connector.READ);
            if (fc.exists()) {
                is = fc.openDataInputStream();
                byte[] tmp = readBytes(is, (int) fc.fileSize());
                img = Image.createImage(tmp, 0, tmp.length);
                is.close();
            }
            fc.close();
        } catch (Exception e) {
        }
        return img;
    }

其中address为文件地址，具体写法参照2楼

byte[] b = new byte[1024];
int len = 0;
ByteArrayOutputchinese wholesalers baos = new ByteArrayOutputStream();
DataOutputStream dos = new DataOutputStream(baos);
while((len = is.read(b)) != -1){
dos.write(b, 0, len);
