您好,我从服务器获取图像时遇到以下异常。在获得以下内容之后,我致力于获取5-7张图像:

我使用这种方法:
public static Bitmap getLargeImage(String imgUrl)
{
Bitmap bitmap = null;
InputStream in = null;
Log.v(TAG,"start fetchimg main images");
try
{
DefaultHttpClient mHttpClient = new DefaultHttpClient();
HttpGet mHttpGet = new HttpGet(imgUrl);
HttpResponse mHttpResponse = mHttpClient.execute(mHttpGet);
if (mHttpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
{
HttpEntity entity = mHttpResponse.getEntity();
if ( entity != null)
{
in = entity.getContent();
BufferedInputStream bis = new BufferedInputStream(in, 8190);
ByteArrayBuffer baf = new ByteArrayBuffer(50);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte)current);
}
byte[] imageData = baf.toByteArray();
BitmapFactory.decodeByteArray(imageData, 0, imageData.length);
if(in != null)
in.close();
}
}
}
catch (Exception ex)
{
Log.v("Error Fetching images from url",ex.getMessage());
}
return bitmap;
}

您是否收到不同主题的图片?如果是,您使用哪个类下载图像?标准的HttpClient不是线程安全的,你应该使用ThreadSafeClientConnManager来获得线程安全的。
