Android 获取网络图片方法

private Bitmap getUrlimg(String url) throws IOException {   

        Bitmap bitmap = null;   

        URL imageUrl = null;   

        String head = "http://114.80.209.134:13080/";   

        String tureUrl = head + url;   

        imageUrl = new URL(tureUrl);   

           

        HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection();   

        conn.connect();   

        InputStream is = conn.getInputStream();   

        BufferedInputStream bis = new BufferedInputStream(is);   

        bitmap =    

        bis.close();   

        is.close();   

  

        return bitmap;   

    }  

以前经常用这种方式获得图片，但是今天发现当图片比较多而且大时，经常 失败，
后来发现  io流的获取没有出错，得到的是完整的io流，但是 还是失败，发现是那个 BitmapFactory.decodeStream(bis);的问题  后来改成这样，见下，可以完全解决问题。

private Bitmap getUrlimg(String url) throws IOException {   

        Bitmap bitmap = null;   

        URL imageUrl = null;   

        String head = "http://114.80.209.134:13080/";   

        String tureUrl = head + url;   

        imageUrl = new URL(tureUrl);   

  

        HttpURLConnection conn = (HttpURLConnection) imageUrl.openConnection();   

        conn.setRequestMethod("GET");   

        conn.setConnectTimeout(5 * 1000);   

        conn.connect();   

        InputStream is = conn.getInputStream();   

        byte[] bt = getBytes(is);   

        bitmap = BitmapFactory.decodeByteArray(bt, 0, bt.length);   

        is.close();   

        conn.disconnect();   

        return bitmap;   

    }   

       

    private byte[] getBytes(InputStream is) throws IOException {   

  

        ByteArrayOutputStream baos =new ByteArrayOutputStream();   

  

        byte[] b =new byte[1024];   

        int len = 0;   

        while ((len = is.read(b, 0, 1024)) !=-1) {   

            baos.write(b, 0, len);   

            baos.flush();   

        }   

        byte[] bytes = baos.toByteArray();   

        return bytes;   

    }
