Use URLs to read network resources in Android

The URL (Uniform Resource Locator) object represents the Uniform Resource Locator, which is a pointer to the Internet "resource".

To read a network resource using a URL:

ImportJava.io.InputStream;ImportJava.net.URL;Importandroid.app.Activity;ImportAndroid.graphics.Bitmap;Importandroid.graphics.BitmapFactory;ImportAndroid.os.Bundle;ImportAndroid.os.Handler;ImportAndroid.widget.ImageView; Public classMainactivityextendsActivity {ImageView show;    Bitmap Bitmap; Handler Handler=NewHandler () { Public voidhandlemessage (android.os.Message msg) {if(Msg.what = = 0x123) {System.out.println ("Handlermsg");            Show.setimagebitmap (bitmap);    }        }    }; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); Show=(ImageView) Findviewbyid (r.id.show); NewThread () { Public voidrun () {Try {                    //System.out.println (url.tostring ());SYSTEM.OUT.PRINTLN (666); //The URL should be the download link to the image;URL url =NewURL ("http://dl.image.so.com/d?imgurl=http%3A%2F%2Fimg.tupianzj.com%2Fuploads%2Fallimg%2F160522% 2f9-160522114s1.jpg&purl=http%3a%2f%2fwww.tupianzj.com%2fgaoxiao%2fbiaoqing%2f20160522%2f50570_7.html& key=72e4826817 ");                    System.out.println (Url.tostring ()); InputStream is=Url.openstream (); Bitmap=Bitmapfactory.decodestream (IS); Handler.sendemptymessage (0x123);                Is.close (); } Catch(Exception e) {e.printstacktrace ();        }            };    }.start (); }}

A URL is used to access the image resource and is displayed, where the URL should be the download link address for the corresponding picture resource.
