Android-未处理的java.net.MalformedURLException

Question

I'm getting a MalformedURLException some code in my Android Studio project. My aim is to get and display an image from a web page, and the URL seems to be fine, but it's giving me this error.

I have already put the code in a try , catch , but that is still giving me the error. Here is the code to grab the image and display it:

    try
    {
        url = new URL(items.get(position).getLink());
        bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
    }
    catch (IOException e)
    {
        throw new RuntimeException("Url Exception" + e);
    }

    holder.itemTitle.setText(items.get(position).getTitle());;
    holder.itemHolder.setBackgroundDrawable(new BitmapDrawable(bmp));

items.get(position).getLink() is meant to get the link that is being displayed in a ListView , but even something like URL url = new URL("https://www.google.com") doesn't work.

Thanks.

Answer 1

your url is formatted without the protocol at the beginning try

url = new URL("http://"+items.get(position).getLink());

sometimes the url string may have special characters, in which case you need to encode it properly please see this . And also, the url you posted in the comment is not an image.

Answer 2

it is exception beacuse of url class

add antoher catch like

catch (MalformedURLException e) {

            e.printStackTrace();
        }

Answer 3

只需单击alt + enter，然后导入try catch部分，这对我有所帮助...
