问题从网页加载图像（机器人） [英] problem loading image from web (android)

问题描述

public Object fetch(String address) throws MalformedURLException,
IOException {
    URL url = new URL(address);
    Object content = url.getContent();
    return content;
}  

private Drawable ImageOperations(Context ctx, String url) {
    try {
        InputStream is = (InputStream) this.fetch(url);
        Drawable d = Drawable.createFromStream(is, "src");
        return d;
    } catch (MalformedURLException e) {
        return null;
    } catch (IOException e) {
        return null;
    }
    catch (Exception e) 
    {
        return null;
    }
}

try {
            Drawable a =ImageOperations(this,"url"); imgView.setImageDrawable(a);
        } catch (Exception e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();

这工作，但在罕见ocasions应用程序冻结由于SocketException：ADRESS协议不支持。有什么办法解决这一问题？谢谢

This works, but on rare ocasions the app freezes due to a "SocketException: Adress family not supported by protocol". Is there any way to fix this? Thanks

推荐答案

您正试图下载从UI线程文件...（这就是为什么你的UI冻结）

You are trying to Download a File from the UI Thread...(which is why your UI Freezes)

使用一个单独的线程或的AsyncTask 让你的UI没有按' ŧ冻结。

Use a Seperate Thread or AsyncTask so that your UI doesn't Freeze up.

这应该解决您的问题。
