这是处理位图的函数，它崩溃的行标记为

public Bitmap loadBitmap() {

    try
    {
        URL url = new URL(pictureURL);   
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoInput(true);
        connection.connect();   //LINE
        InputStream input = connection.getInputStream();
        Bitmap myBitmap = BitmapFactory.decodeStream(input);

        return myBitmap;
    }
    catch (IOException e) {
        e.printStackTrace();
        return null;
    }

}

PictureURL = http://event-cloud.co.uk/events/uploads/images/eventthumb.png

Answer 1

它需要http://或您想要的任何其他协议。 pictureURL的价值是什么？

Answer 2

你得到NetworkOnMainThreadException。这意味着，您正在UI线程上执行网络操作。使用AsyncTask。

图片不会从URL android加载
