Android Load Network GIF pictures

GIF-enabled ImageView, using the open source framework on GitHub, project address https://github.com/koral--/android-gif-drawable

If GIF is a network image, this library does not support loading a URL directly, but provides a gifdrawable class that can create gifdrawable through files, input streams, and so on .

So you can download it first or get the input stream by creating a drawable load. The following examples illustrate two methods:

1. Download to SD card, then load

Downloadutils.java

 Public classDownloadutils {Private Final intDown_start = 1;//Handler message type (start download)    Private Final intDown_position = 2;//handler message type (download location)    Private Final intDown_complete = 3;//handler message type (download complete)    Private Final intDown_error = 4;//handler message type (download failed)    PrivateOndownloadlistener Ondownloadlistener;  Public voidSetondownloadlistener (Ondownloadlistener ondownloadlistener) { This. Ondownloadlistener =Ondownloadlistener; }    /*** Download File * *@paramURL file path *@paramfilepath Save Address*/     Public voidDownload (string URL, string filepath) {myrunnable Mr=Newmyrunnable (); Mr.url=URL; Mr.filepath=filepath; NewThread (MR). Start (); } @SuppressWarnings ("Unused")    Private voidSendmsg (intWhat ) {sendmsg (What,NULL); }    Private voidSendmsg (intWhat , Object mess) {Message m=Myhandler.obtainmessage (); M.what=what ; M.obj=mess;    M.sendtotarget (); } Handler MyHandler=NewHandler () { Public voidhandlemessage (Message msg) {Switch(msg.what) { CaseDown_start://Start Download                    intFileSize =(Integer) msg.obj;                    Ondownloadlistener.ondownloadconnect (filesize);  Break;  CaseDown_position://Download Location                    intpos =(Integer) msg.obj;                    Ondownloadlistener.ondownloadupdate (POS);  Break;  CaseDown_complete://Download CompleteString URL =(String) msg.obj;                    Ondownloadlistener.ondownloadcomplete (URL);  Break;  CaseDown_error://Download FailedException e =(Exception) msg.obj;                    E.printstacktrace ();                    Ondownloadlistener.ondownloaderror (e);  Break; }            Super. Handlemessage (msg);    }    }; classMyrunnableImplementsRunnable {PrivateString url = ""; PrivateString filepath = ""; @Override Public voidrun () {Try{dodownloadthefile (URL, filepath); } Catch(Exception e) {sendmsg (Down_error, E); }        }    }    /*** Download File * *@paramURL Download Path *@paramfilepath Save path *@throwsException*/    Private voidDodownloadthefile (string URL, string filepath)throwsException {if(!urlutil.isnetworkurl (URL)) {sendmsg (Down_error,NewException ("not valid:" +URL)); return; } URL Myurl=Newurl (URL); URLConnection Conn=myurl.openconnection ();        Conn.connect (); InputStream is=NULL; intFileSize = 0; Try{ is=Conn.getinputstream (); FileSize= Conn.getcontentlength ();//get file size based on responsesendmsg (Down_start, filesize); } Catch(Exception e) {sendmsg (Down_error,NewException (NewException ("Cannot get File"))); return; } FileOutputStream Fos=NewFileOutputStream (filepath);//creates a write-to-file memory stream,//write a file with this flow to target        byteBuf[] =New byte[1024]; intNumread = 0; inttemp = 0;  while((Numread = Is.read (BUF))! =-1) {fos.write (buf,0, Numread);            Fos.flush (); Temp+=Numread;        Sendmsg (down_position, temp);        } is.close ();        Fos.close ();    Sendmsg (Down_complete, filepath); }}

Download monitoring in Activity settings

Downloadutils downloadutils =Newdownloadutils (); Downloadutils.download ("Http://img15.3lian.com/2015/gif/1/78/1.gif", Getapppath () + "/1.gif"); Downloadutils.setondownloadlistener (NewOndownloadlistener () {@Override Public voidOndownloadupdate (intpercent) {} @Override Public voidOndownloaderror (Exception e) {} @Override Public voidOndownloadconnect (intfilesize) {} @Override Public voidondownloadcomplete (Object result) {Try{gifdrawable gifdrawable=NewGifdrawable (Getapppath () + "/1.gif");                Gifimageview.setbackgrounddrawable (gifdrawable); } Catch(IOException e) {e.printstacktrace (); }            }        });

2. Get byte [] type stream, create drawable, use network request frame Commons-httpclient-3.0.1.jar

Loadgifutils loadgifutils =Newloadgifutils (); Loadgifutils.setlistener (NewLoadgifutils.oncompltedlistener () {@Override Public voidOncomplted (byte[] bt) {                Try{gifdrawable drawable=Newgifdrawable (BT);                Gifimageview.setbackgrounddrawable (drawable); } Catch(IOException e) {e.printstacktrace ();        }            }        }); Loadgifutils.loadgif ("Http://img15.3lian.com/2015/gif/1/78/1.gif");

Loadgifutils.java

 Public classLoadgifutils {PrivateOncompltedlistener Listener;  Public voidloadgif (String url) {myrunnable myrunnable=Newmyrunnable (URL); NewThread (myrunnable). Start (); }    classMyrunnableImplementsRunnable {String URL; myrunnable (String URL) { This. url =URL; } @Override Public voidrun () {byte[] bt=New byte[1024]; Try{HttpClient Client=NewHttpClient (); GetMethod Get=Newgetmethod (URL);                Client.executemethod (get); BT=Get.getresponsebody (); Sendmsg (1, BT); } Catch(Throwable ex) {System.out.println (ex.tostring ()); }        }    }    Private voidSendmsg (intWhat , Object mess) {Message m=Handler.obtainmessage (); M.what=what ; M.obj=mess;    M.sendtotarget (); } Handler Handler=NewHandler () {@Override Public voidhandlemessage (Message msg) {Switch(msg.what) { Case1://Start Download                    byte[] bt = (byte[]) msg.obj; if(listener!=NULL) {listener.oncomplted (BT); }                     Break; }            Super. Handlemessage (msg);    }    }; InterfaceOncompltedlistener {voidOncomplted (byte[] bt); }    voidSetlistener (Oncompltedlistener listener) { This. listener=Listener; }}
