The Almighty Volley

V1olley capable of those things? Send a GET request

public void Getjson () {String URL = "//" +host+ ": 8080/web/json.jsp?username=xjs&password=123456"; Mqueue.add ( New Jsonobjectrequest (Method.get, URL, null,new Listener () {@Overridepublic void Onresponse (jsonobject response) {LOG.E (TAG, "response:" + response.tostring ())}, new Response.errorlistener () {@Overridepublic void Onerrorresponse ( Volleyerror error) {String err = error.getmessage (); LOG.E (TAG, "ERR:" + err);}));
Volley Send POST request:

public void Postjson () {String URL = "//" +host+ ": 8080/web/json.jsp"; Stringrequest postrequest = new Stringrequest (Request.Method.POST, Url,new Response.listener () {@Overridepublic void Onresponse (String response) {//RESPONSELOG.D ("response", Response),}}, New Response.errorlistener () {@Overridepublic void Onerrorresponse (Volleyerror error) {//ERRORLOG.D ("Error.response", Error.getmessage ())}) {@Overrideprotected Map getparams () {Map params = new HashMap ();p arams.put ("username", "XJS");p arams.put ("Password", " 123456 "); return params;}; Mqueue.add (postrequest);}
3.

Volley Get network pictures:

public void GetImage () {String imageUrl = "/http" +host+ ": 8080/web/image.jsp"; Networkimageview view = (Networkimageview) Findviewbyid (R.id.network_image_view); View.setdefaultimageresid (Android . R.drawable.ic_menu_rotate); View.seterrorimageresid (Android. R.drawable.ic_delete); View.setimageurl (IMAGEURL, New Imageloader (Mqueue, New Bitmaplrucache (1024 * 4));}

4 Volley send HTTPS request, need to modify the source code:

protected httpurlconnection createconnection (url url) throws IOException {if (url.tostring () toLowerCase (Locale.china ). StartsWith ("https")) {Httpstrustmanager.allowallssl ();} Return (HttpURLConnection) url.openconnection ();} HTTPSTrustManager.java:public class Httpstrustmanager implements X509trustmanager {private static trustmanager[] Trustmanagers;private static final x509certificate[] _acceptedissuers = new x509certificate[] {}; @Overridepublic void Checkclienttrusted (java.security.cert.x509certificate[] x509certificates, String s) throws Java.security.cert.CertificateException {//To change body of implemented methods use File | Settings | file//Templates.} @Overridepublic void checkservertrusted (java.security.cert.x509certificate[] x509certificates, String s) throws Java.security.cert.CertificateException {//To change body of implemented methods use File | Settings | file//Templates.} public boolean isclienttrusted (x509certificate[] chain) {return true;} public Boolean IsservertrusteD (x509certificate[] chain) {return true;} @Overridepublic x509certificate[] Getacceptedissuers () {return _acceptedissuers;} public static void Allowallssl () {Httpsurlconnection.setdefaulthostnameverifier (new Hostnameverifier () {@ Overridepublic Boolean Verify (String arg0, sslsession arg1) {//TODO auto-generated method Stubreturn true;}}); Sslcontext context = null;if (trustmanagers = = null) {trustmanagers = new trustmanager[] {new Httpstrustmanager ()};} try {context = Sslcontext.getinstance ("TLS"), Context.init (null, trustmanagers, New SecureRandom ());} catch ( NoSuchAlgorithmException e) {e.printstacktrace ();} catch (Keymanagementexception e) {e.printstacktrace ();} Httpsurlconnection.setdefaultsslsocketfactory (Context.getsocketfactory ());}}

5 Volley Gets the cookie returned by the server and needs to modify the source code:

@Overridepublic HttpResponse performrequest (request> request,map additionalheaders) throws IOException, Authfailureerror {for (entry> header:connection.getHeaderFields (). EntrySet ()) {if (Header.getkey ()! = null) {String Key = Header.getkey (); List values = Header.getvalue (), if (Key.equalsignorecase ("Set-cookie")) {StringBuilder cookiestring = new StringBuilder (); for (String value:values) {cookiestring.append (value). Append ("\ n");//\ n As a delimiter, there should be no carriage return symbol in the cookie} Cookiestring.deletecharat (Cookiestring.length ()-1); Header h = new Basicheader (Header.getkey (), cookiestring.tostring ()); Response.AddHeader (h);} Else{header h = new Basicheader (Header.getkey (), Values.get (0)); Response.AddHeader (h);}}} Then rewrite the request in Parsenetworkresponse (): @Overrideprotected Response parsenetworkresponse (networkresponse Response) { Response superresponse = Super.parsenetworkresponse (Response); Map responseheaders = response.headers; String rawcookies = Responseheaders.get ("Set-cookie");//server return is SET-COOKIE:JSESSIONID=D90b58454550b4d37c4b66a76bf27b93; Path=/otn bigipserverotn=2564030730.64545.0000; path=/string part1 = substring (rawcookies, "", ";"); String part2 = substring (rawcookies, "\ n", ";"); /The client needs to be cookie:jsessionid=d90b58454550b4d37c4b66a76bf27b93; Bigipserverotn=2564030730.64545.0000;cookies = Part1 + ";" + Part2 + ";"; return superresponse;}

6 Volley upload a cookie when requested, rewrite Getheaders () in Request:

@Overridepublic Mapgetheaders () throws Authfailureerror {         if (cookies!= null && cookies.length () > 0) {                   HashMap         headers = Newhashmap ();                   Headers.put ("cookies", cookies);                   returnheaders;         }         Returnsuper.getheaders ();}

7 Volley Custom Request:

public class Bytearrayrequest extends Request{private final Listener mlistener;public bytearrayrequest (int method, String URL, Listener Listener, Errorlistener Errlistener) {Super (method, URL, errlistener); mlistener = Listener;} @Overrideprotected Response parsenetworkresponse (networkresponse Response) {if (Response = = null) {return null;} if (response.statuscode! = HTTPSTATUS.SC_OK) {return null;} byte[] bytes = Response.data;return response.success (bytes, null);} @Overrideprotected void Deliverresponse (byte[] response) {if (Mlistener! = null) {mlistener.onresponse (response);}}}

8 Volley set Request time-out:

@Overridepublic Retrypolicy Getretrypolicy () {          retrypolicyretrypolicy = new Defaultretrypolicy (5000, Defaultretrypolicy.default_max_retries, Defaultretrypolicy.default_backoff_mult);          Returnretrypolicy; }

About picture loading:

Requestqueue Mqueue = volley.newrequestqueue (context);
Imageloader Imageloader = new Imageloader (Mqueue, New Bitmapcache ());

Imagelistener listener = Imageloader.getimagelistener (Ivadvertise,
R.drawable.defaulto, R.drawable.error);//

Imageloader.get (head_img, Listener, 200, 200);

public class Bitmapcache implements Imagecache {

Private lrucache<string, bitmap> Mcache;

Public Bitmapcache () {
int maxSize = 10 * 1024 * 1024;
Mcache = new lrucache<string, bitmap> (maxSize) {

@Override
protected int sizeOf (String key, Bitmap value) {
TODO auto-generated Method Stub
return Value.getrowbytes () * Value.getheight ();
}
};
}

@Override
Public Bitmap getbitmap (String URL) {
TODO auto-generated Method Stub
return Mcache.get (URL);
}

@Override
public void Putbitmap (String URL, Bitmap BM) {
TODO auto-generated Method Stub
Mcache.put (URL, BM);
}
}

Wide height can not be set about
