Android: how to display network images

Displaying a network image in Android is actually super simple. The following is a very simple example: Step 1: 1. Create your activity. In this example, viewwebimageactivity is described. 2. In viewwebimageactivity Code String imageurl = "http://hiphotos.baidu.com/baidu/pic/item/7d8aebfebf3f9e125c6008d8.jpg"; // This is the network picture you need to display --- the bitmap bmimg; imageview imview; button button1; @ override public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main); imview = (imageview) findviewbyid (R. id. imview); imview. setimagebitmap (returnbitmap (imageurl);} public bitm AP returnbitmap (string URL) {URL myfileurl = NULL; Bitmap bitmap = NULL; try {myfileurl = new URL (URL);} catch (malformedurlexception e) {e. printstacktrace ();} Try {httpurlconnection conn = (httpurlconnection) myfileurl. openconnection (); Conn. setdoinput (true); Conn. connect (); inputstream is = Conn. getinputstream (); bitmap = bitmapfactory. decodestream (is); is. close ();} catch (ioexception E) {E. printstacktrace () ;}return bitmap;} 3. The returnbitmap (string URL) method converts a network image to a bitmap. Step 2: 1. Modify your main. xml file as follows: <? XML version = "1.0" encoding = "UTF-8"?> <Linearlayout xmlns: Android = "http://schemas.android.com/apk/res/android" Android: Orientation = "vertical" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent"> <imageview Android: id = "@ + ID/imview" Android: layout_width = "wrap_content" Android: layout_height = "wrap_content" Android: layout_gravity = "center"/> </linearlayout> Step 3: 1. In your androidmanifest. add <uses-Permission Android: Name = "android. Permission. Internet"/>. This is because android has many permission restrictions. Otherwise, Images cannot be displayed on your simulator.
