Question

我想在片段中添加url图片，但我无法做到。

   URL imageUrl = new URL("http://image10.bizrate-images.com/resize?sq=60&uid=2216744464");

public HomeFragment() throws MalformedURLException {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_home, container, false);

    try {
        ImageView i = (ImageView)rootView.findViewById(R.id.image);
        Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(imageUrl).getContent());
        i.setImageBitmap(bitmap);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return rootView;
}

显示错误

Answer 1

您可以使用Picasso从网址加载图片。

Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

或使用Glide

Glide.with(fragment).load(myUrl).into(imageView);

试试这段代码：

public HomeFragment() throws MalformedURLException {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_home, container, false);

    try {
        URL imageUrl = new URL("http://image10.bizrate-images.com/resize?sq=60&uid=2216744464");
        ImageView i = (ImageView)rootView.findViewById(R.id.image);
        Bitmap bitmap = BitmapFactory.decodeStream(imageUrl.openConnection().getInputStream());
        i.setImageBitmap(bitmap);
    } catch (Exception e) {
        e.printStackTrace();
    }
    return rootView;
}
