android - How to use callback for multiple json array in retrofit? -

i trying retrofit how data below response

 {"schedule_students":[{"id":"753","sch_id":"153"},{"id":"765","sch_id":"153"}],     "s_students":[{"id":"753","s_id":"153"},{"id":"765","s_id":"153"}],     "schedu":[{"id":"753","ch_id":"153"},{"id":"765","ch_id":"153"}],     "delids":"no","expdelids":"no","lastsyncdate":"2015-06-01 10:33:19"} 

in api response it's having multiple json array. how retrieve data response

create pojos (plain old java objects) json data sets. use tool generate pojos.

sstudent.class

package com.example.someapp;  import com.google.gson.annotations.expose; import com.google.gson.annotations.serializedname;  package com.example.someapp;  import com.google.gson.annotations.expose; import com.google.gson.annotations.serializedname;  public class sstudent {      @expose     private string id;     @serializedname("s_id")     @expose     private string sid;      /**     *      * @return     * id     */     public string getid() {     return id;     }      /**     *      * @param id     * id     */     public void setid(string id) {     this.id = id;     }      /**     *      * @return     * sid     */     public string getsid() {     return sid;     }      /**     *      * @param sid     * s_id     */     public void setsid(string sid) {     this.sid = sid;     }  } 

similarly, other generate other classes.

and finally,

someclass.java

package com.example.someapp;  import java.util.arraylist; import java.util.list; import javax.annotation.generated; import com.google.gson.annotations.expose; import com.google.gson.annotations.serializedname;  public class someclass {      @serializedname("schedule_students")     @expose     private list<schedulestudent> schedulestudents = new arraylist<schedulestudent>();     @serializedname("s_students")     @expose     private list<sstudent> sstudents = new arraylist<sstudent>();     @expose     private list<schedu> schedu = new arraylist<schedu>();     @expose     private string delids;     @expose     private string expdelids;     @expose     private string lastsyncdate;      /**     *      * @return     * schedulestudents     */     public list<schedulestudent> getschedulestudents() {     return schedulestudents;     }      /**     *      * @param schedulestudents     * schedule_students     */     public void setschedulestudents(list<schedulestudent> schedulestudents) {     this.schedulestudents = schedulestudents;     }      /**     *      * @return     * sstudents     */     public list<sstudent> getsstudents() {     return sstudents;     }      /**     *      * @param sstudents     * s_students     */     public void setsstudents(list<sstudent> sstudents) {     this.sstudents = sstudents;     }      /**     *      * @return     * schedu     */     public list<schedu> getschedu() {     return schedu;     }      /**     *      * @param schedu     * schedu     */     public void setschedu(list<schedu> schedu) {     this.schedu = schedu;     }      /**     *      * @return     * delids     */     public string getdelids() {     return delids;     }      /**     *      * @param delids     * delids     */     public void setdelids(string delids) {     this.delids = delids;     }      /**     *      * @return     * expdelids     */     public string getexpdelids() {     return expdelids;     }      /**     *      * @param expdelids     * expdelids     */     public void setexpdelids(string expdelids) {     this.expdelids = expdelids;     }      /**     *      * @return     * lastsyncdate     */     public string getlastsyncdate() {     return lastsyncdate;     }      /**     *      * @param lastsyncdate     * lastsyncdate     */     public void setlastsyncdate(string lastsyncdate) {     this.lastsyncdate = lastsyncdate;     }  } 

use someclass.java in retrofit api interface this.

 @get("/your_api_endpoint")  someclass getsomeclass(@query("param") int param); 

then access object of someclass after calling getsomeclass(param).
