Android View Network Picture example

1. Layout files

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http// Schemas.android.com/tools "android:layout_width=" match_parent "android:orientation=" vertical "Android:layout_heig ht= "Match_parent" tools:context= ". Mainactivity "> <imageview android:id=" @+id/iv_icon "android:layout_width=" Match_parent "and roid:layout_height= "Wrap_content" android:layout_weight= "1"/> <linearlayout android:layout_wid Th= "Match_parent" android:layout_height= "wrap_content" android:orientation= "Horizontal" > & Lt EditText android:id= "@+id/et_url" android:layout_height= "Wrap_content" Android:layout_wi Dth= "0dip" android:text= "Http://img0.bdstatic.com/img/image/shouye/dengni37.jpg" android:singleline= "True" android:layout_weight= "1"/> <button android:id= "@+id/btn_submit" and Roid:layout_height= "Wrap_content" android:layout_width= "wrap_content" android:text= "Go"/> </Li Nearlayout></linearlayout>

2. Implementation in the main program

Package Com.wzw.netphoto;import Java.io.inputstream;import Java.net.httpurlconnection;import Java.net.malformedurlexception;import Java.net.url;import Android.os.bundle;import Android.app.Activity;import Android.graphics.bitmap;import Android.graphics.bitmapfactory;import Android.view.menu;import Android.view.View; Import Android.view.view.onclicklistener;import Android.widget.button;import Android.widget.edittext;import Android.widget.imageview;import Android.widget.toast;public class Mainactivity extends Activity implements Onclicklistener {private ImageView ivicon;private EditText eturl; @Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.activity_main); IvIcon = ( ImageView) Findviewbyid (r.id.iv_icon); Eturl = (EditText) Findviewbyid (R.id.et_url); Button btn= (button) Findviewbyid (r.id.btn_submit); Btn.setonclicklistener (this);} @Overridepublic void OnClick (View v) {String url=eturl.gettext (). toString (); Bitmap BIT=GETIMAGEFRomnet (URL); ivicon.setimagebitmap (bit);} Public Bitmap getimagefromnet (String url) {try {url murl=new url (URL);//Create URL object HttpURLConnection conn = (  httpurlconnection) murl.openconnection (); Conn.setrequestmethod ("GET"); Conn.setconnecttimeout (10000); Set the connection timeout time conn.setreadtimeout (5000);//Set Read timeout conn.connect (); int responsecode = Conn.getresponsecode (); if ( responsecode==200) {InputStream is = Conn.getinputstream (); Bitmap Bitmap=bitmapfactory.decodestream (IS); Toast.maketext (This, "Get Success", 0). Show (); return bitmap;}} catch (Exception e) {e.printstacktrace ();} return null;}}

3. Add Network access rights

<?xml version= "1.0" encoding= "Utf-8"? ><manifest xmlns:android= "http://schemas.android.com/apk/res/        Android "package=" Com.wzw.netphoto "android:versioncode=" 1 "android:versionname=" 1.0 "> <uses-sdk android:minsdkversion= "8" android:targetsdkversion= "/>", <!--Add permissions to access the network and <uses-permiss Ion Android:name= "Android.permission.INTERNET"/> <application android:allowbackup= "true" Android:ic on= "@drawable/ic_launcher" android:label= "@string/app_name" android:theme= "@style/apptheme" > <            Activity android:name= "com.wzw.netphoto.MainActivity" android:label= "@string/app_name" > <intent-filter> <action android:name= "Android.intent.action.MAIN"/> <cate Gory android:name= "Android.intent.category.LAUNCHER"/> </intent-filter> </activity> & Lt;/application></manifest>
