获取网络图片出现异常，该如何解决，求大神

[ad_789]

path = "http://www.baidu.com/img/baidu_sylogo1.gif";
PrintUtil.log("=====", "======" + path);
viewHolder.tuijian_imageView.setImageBitmap(addImage());




private Bitmap addImage() {
Bitmap bitmap = null;

try {
byte[] data = getImage(path);
bitmap = BitmapFactory.decodeByteArray(data, 0,

data.length);

// tuijian_imageView.setImageBitmap(bitmap);

} catch (Exception e) {

// Toast.makeText(getActivity(), R.string.error, 1).show();

Log.e(TAG + "加载图片异常", e.toString());

}
return bitmap;
}

public static byte[] getImage(String path) throws Exception {

URL url = new URL(path);

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

conn.setRequestMethod("GET");

conn.setConnectTimeout(5 * 1000);

InputStream inStream = conn.getInputStream();

return readFromInput(inStream);

}

public static byte[] readFromInput(InputStream inStream) throws Exception {

ByteArrayOutputStream outStream = new ByteArrayOutputStream();

byte[] buffer = new byte[1024];

int len = 0;

while ((len = inStream.read(buffer)) != -1) {

outStream.write(buffer, 0, len);

}

inStream.close();

return outStream.toByteArray();

}

总是报错，谁知道什么原因啊啊

android.os.NetworkOnMainThreadException很明显啊，联网操作不能在主线程，再开个线程把联网的操作写到新的线程里就好了

http://doinone.iteye.com/blog/1074283 参考这个的第三种方法。 直接操作主线程容易让UI卡死，所以推荐后台线程操作，。

android 4.0以后不能在UI线程进行网络操作，用thread + handler处理网络操作吧
