java - ArrayAdapter using ArrayList but display only 1 value of an array on Spinner -

-

i have arraylist<string[]> lstprovinceinfo this

{"id":"1","province_code":"hni","province_name":"hà nội"}, {"id":"2","province_code":"hcm","province_name":"tp hồ chí minh"}, {"id":"3","province_code":"dng","province_name":"Đà nẵng"}

now i'm creating arrayadapter use spinner dropdown this

arrayadapter<string[]> adapter = new arrayadapter<>(this, r.layout.custom_ddlist, lstprovinceinfo); adapter.setdropdownviewresource(android.r.layout.simple_spinner_dropdown_item);

the display result got in spinner is: 

[ljava.lang.string;@3286c7b8 [ljava.lang.string;@3286c808 [ljava.lang.string;@3286c818

how can display "province_name" part in arraylist on spinner still keep follwing id, province_code? in advanced.

create customarrayadapter ....

you won;t allow pass arraylist (arraylist of string array) set actual parameter pass arrayadapter arraylist .. hence in case object of string array been passed , internally string[].tostring() called .

public class customarrayadapter extends baseadapter {      private arraylist<string[]> list;      private context mcontext;      private int resid;       public customarrayadapter(context mcontext,int resid, arraylist<string[]> list)      {             this.mcontext=mcontext;             this.resid=resid;             this.list=list;      }       //override getview method      //override getcount method , others }

now pass arraylist customarrayadapter , set adapter list or spinner
