[Android] Is it possible to use BitmapFactory.decodeFile method to decode a image from http location? (轉貼)

Is it possible to use BitmapFactory.decodeFile method to decode a image from http location?

ImageView iv = new ImageView(context);
 
try{ 
    String url1 = "http://<my IP>/test/abc.jpg";
    URL ulrn = new URL(url1);
    HttpURLConnection con = (HttpURLConnection)ulrn.openConnection();
    InputStream is = con.getInputStream();
    Bitmap bmp = BitmapFactory.decodeStream(is);
    if (null != bmp)
        iv.setImageBitmap(bmp);
    else 
        System.out.println("The Bitmap is NULL");
 
} catch(Exception e) {
} 

Do not forget to disconnect (and hereby release the input stream resource), e.g. finally { if (con != null) { con.disconnect(); } }

[Android] disable scrolling motion in the listview

XML Layout

android:scrollbars="none"






android:scrollbars will define which scrollbars to display or show any at all. This won’t disable scrolling as such (you’ll be able to scroll in the appropriate direction) but just hide the scrollbars from the user interface. More of a UI switch.

Programatically, you can call View.setVerticalScrollBarEnabled(boolean) andView.setHorizontalScrollBarEnabled(boolean) for similar effect.
