如何接收的字节数组并将其转换成图像中的Andr​​oid？ [英] How to receive a byte array and convert it to image in Android?

问题描述

我用：

InputStream in;
Bitmap bmp=BitmapFactory.decodeStream(in);

但过程等待时间长，没有任何反应。在服务器端，我有图像转换成字节[]。

but the process waits for a long time and nothing happens. On the server side, i have the image converted into byte[].

推荐答案

我觉得这块code将是对您有用：

I think this piece of code will be useful for you:

public Bitmap DownloadImage(String url)
{
    HttpClient client = new DefaultHttpClient();
    HttpResponse httpResponse;
    Bitmap bmp = null;

    try{
       httpResponse = client.execute(new HttpGet(url));
       responseCode = httpResponse.getStatusLine().getStatusCode();

       HttpEntity entity = httpResponse.getEntity();

       if (entity != null)
       {
           InputStream in = entity.getContent();
           bmp = BitmapFactory.decodeStream(in);
           in.close();
       }
    } catch (ClientProtocolException e)  {
        client.getConnectionManager().shutdown();
        e.printStackTrace();
    } catch (IOException e) {
        client.getConnectionManager().shutdown();
        e.printStackTrace();
    }   
    return bmp;
}
