android从服务器下载文件(php+apache+win7+MySql)

举例：android从apache服务器获取文件(图像)，保存到相应的目录中，并从目录中将图像转变为Bitmap

 /* * 参数 ：将要获取的服务器文件名 filename * 如果成功，返回真*/boolean getImageByWeb2(String filename) {     File img = new File(TEMP_WEB_IMAGE_PATH + filename);     // Create directories     new File(TEMP_WEB_IMAGE_PATH).mkdirs();    // only download new images     if (!img.exists()) {         try {             URL imageUrl = new URL("http://10.10.145.154/WebImageProcess/output/" + filename);             InputStream in = imageUrl.openStream();             OutputStream out = new BufferedOutputStream(new FileOutputStream(img));              for (int b; (b = in.read()) != -1;) {                 out.write(b);             }             out.close();             in.close();         } catch (MalformedURLException e) {             img = null;            return false;         } catch (IOException e) {             img = null;            return false;         }     }     return true; }

调用：

if(getImageByWeb2("processed_"+serverFileName)){    //将保存完毕的图像，转变为Bitmap格式    Bitmap resultForWebImage=FilesToBitmap(TEMP_WEB_IMAGE_PATH+"processed_"+serverFileName);}

附属代码：

private static final String TEMP_WEB_IMAGE_PATH="/sdcard/app/tmp/";Bitmap FilesToBitmap(String filename){    Bitmap temp=null;    if(filename!=null){        File imageFile = new File(filename);            if (imageFile.exists())            {            // Load the image from file            temp = BitmapFactory.decodeFile(filename);            }            }    return temp;}
