Nohttp is a dedicated framework for Android network requests and downloads, Nohttp basic usage is as follows

The example in this article is from the originalactivity in the demo above.


For beginners, it's a little bit harder to look at other people's packaged code, especially a framework, so let's look at the most primitive uses of nohttp:

The public class Originalactivity extends Baseactivity implements View.onclicklistener {/** * is used to flag the requested what, similar to handler WHA

 T, here is used to differentiate the request * * private static final int nohttp_what_test = 0x001;

 /** * Request time waiting box/private Waitdialog mwaitdialog;

 /** * Request Queue * * Private requestqueue requestqueue; @Override protected void Onactivitycreate (Bundle savedinstancestate) {settitle ().
  Setcontentview (r.layout.activity_original);

  Click on the button to listen Findview ( Setonclicklistener (this);

  Mwaitdialog = new Waitdialog (this);
  Create request queue, default concurrent 3 requests, incoming number change concurrent quantity: Nohttp.newrequestqueue (1);
 Requestqueue = Nohttp.newrequestqueue ();  @Override public void OnClick (View v) {//Create request object Request<string> requests = Nohttp.createstringrequest (URL,;
  Add request parameter Request.add ("UserName", "Yolanda");
  Request.add ("Userpass", 1);

  Request.add ("Userage", 1.25); Upload file Request.add ("Userhead", New FilebinaRy (new File (path));

  Add Request Header Request.addheader ("Author", "nohttp_sample"); A tag is set to return intact at the end of the request (failure/success);

  In most cases you do not need//Request.settag (object); * * What: When multiple requests use the same onresponselistener at the same time to differentiate the request, similar to handler what * Request: Requests Object * Onresponselistener callback object, accept request
 Results * * REQUESTQUEUE.ADD (nohttp_what_test, request, Onresponselistener); /** * Callback object, accept request result/private onresponselistener<string> Onresponselistener = new Onresponselistener<stri
   Ng> () {@SuppressWarnings ("unused") @Override public void onsucceed (int what, response<string> Response) {
    if (what = = Nohttp_what_test) {//Determine if what is the request//request succeeded just specified String result = Response.get ()//Response results//Response header
    Headers Headers = Response.getheaders (); Headers.getresponsecode ()//Response code Response.getnetworkmillis ()//Request time spent}} @Override public void OnStart (in
  T what) {//Request start, Display dialog (); @Override public void onfinish (int what) {//end of request, Close dialog Mwaitdialog.dismiss (); @Override public void onfailed (int what, String URL, Object tag, charsequence error, int rescode, long ms) {//
 Request failed ...}

  @Override protected void OnDestroy () {Super.ondestroy ();

 Requestqueue.cancelall ()//Stop all requests requestqueue.stop () when exiting app//stop queue when exiting app}}
