java - How to add asyncTask code in application? -

i have register activity in application. has inputs of userid,email,password , mobile no. have created ui.

code:

public class registeractivity extends appcompatactivity {      textview already;     button signup;     relativelayout parent;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_register);          parent = (relativelayout)findviewbyid(r.id.parentpanel);          setupui(parent);          = (textview)findviewbyid(r.id.alreadyregistered);         signup = (button) findviewbyid(r.id.sign_up_button);          already.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                  startactivity(new intent(registeractivity.this,loginactivity.class));              }         });           signup.setonclicklistener(new view.onclicklistener() {             @override             public void onclick(view v) {                  startactivity(new intent(registeractivity.this,loginactivity.class));              }         });       }     public static void hidesoftkeyboard(activity activity) {         inputmethodmanager inputmethodmanager = (inputmethodmanager)  activity.getsystemservice(activity.input_method_service);         inputmethodmanager.hidesoftinputfromwindow(activity.getcurrentfocus().getwindowtoken(), 0);     }     public void setupui(view view) {          //set touch listener non-text box views hide keyboard.         if(!(view instanceof edittext)) {              view.setontouchlistener(new view.ontouchlistener() {                  public boolean ontouch(view v, motionevent event) {                     hidesoftkeyboard(registeractivity.this);                     return false;                 }              });         }          //if layout container, iterate on children , seed recursion.         if (view instanceof viewgroup) {              (int = 0; < ((viewgroup) view).getchildcount(); i++) {                  view innerview = ((viewgroup) view).getchildat(i);                  setupui(innerview);             }         }     } } 

now want sync ui server.

for have code of asynctask created in activity. how can call code or implement code ui?

asynctask code : registeractivity

public class registeractivity extends appcompatactivity {     context context;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_register);         context = this;          registerasynctask task = new registerasynctask();         string userphoto = "ivborw0kggoaaaansuheugaaaeaaaabacayaaacqaxheaaaabhncsvqicagifahkiaaaaalwsfllbaihagdimrn7hh1jkkmzz+d7mpu15md6ptcyrhmqvsgnvjy7djh69ogweau1pkvwankk0nlssgva8vk=";          hashmap<string, string> params = new hashmap<string, string>();         params.put("userusername", "user1");         params.put("userpassword", "user1");         params.put("gender", "m");         params.put("birthdate", "1986/7/12");         params.put("religion", "hindu");         params.put("nationality", "indian");         params.put("mothertongue", "marathi");         params.put("birthplace", "pune");         params.put("usercountry", "india");         params.put("userstate", "maharashtra");         params.put("usercity", "nashik");         params.put("userpincode", "422101");         params.put("useremailid", "user1@gmail.com");         params.put("usermobileno", "9696323252");         params.put("userphoto", userphoto);     }    public class registerasynctask extends asynctask<map<string, string>, void, jsonobject>{        @override        protected jsonobject doinbackground(map<string, string>... params) {            try {                string api = context.getresources().getstring(r.string.server_url) + "api/user/register.php";                map2json mjs = new map2json();                jsonobject jsonparams = mjs.getjson(params[0]);                serverrequest request = new serverrequest(api, jsonparams);                return request.sendrequest();            } catch(jsonexception je) {                return excpetion2json.getjson(je);            }        }         @override        protected void onpostexecute(jsonobject jsonobject) {            super.onpostexecute(jsonobject);             log.d("serverresponse", jsonobject.tostring());            try {                int result = jsonobject.getint("result");                string message = jsonobject.getstring("message");                if ( result == 1 ) {                    toast.maketext(context, message, toast.length_long).show();                    //code having successful result register api goes here                } else {                    toast.maketext(context, message, toast.length_long).show();                    //code when api fails goes here                }             } catch(jsonexception je) {                je.printstacktrace();                toast.maketext(context, je.getmessage(), toast.length_long).show();            }        }    } } 

how can sync this? please help. thank you.

edit:

geteventsasynctask:

in dialog want show events asynctask. thank you.

not sure if understand question correctly, execute asynctask, have create instance of registerasynctask , call execute() method on it.

registerasynctask task = new registerasynctask(); task.execute(yourmap); // can pass multiple params execute() method 

or, if don't need ahold of instance:

new registerasynctask().execute(yourmap);
