listactivity.java

public class listactivity extends appcompatactivity implements asyncresponse, adapterview.onitemclicklistener {   public static final int notification_id = 1;  final string log = "listactivity";  private arraylist<product> productlist; private listview lvproduct; private fundapter<product> adapter;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_list);      imageloader.getinstance().init(uilconfig.config(listactivity.this));      postresponseasynctask taskread = new postresponseasynctask(listactivity.this, this);       //taskread.execute("http://10.0.3.2/customer/product.php");      taskread.execute("http://symphonyrecords.6te.net/product.php");      lvproduct = (listview)findviewbyid(r.id.lvproduct);      registerforcontextmenu(lvproduct);   }//oncreate   @override public void processfinish(string s) {     productlist = new jsonconverter<product>().toarraylist(s, product.class);      binddictionary<product> dict = new binddictionary<product>();     dict.addstringfield(r.id.tvname, new stringextractor<product>() {         @override         public string getstringvalue(product product, int position) {             return product.name;         }     });      dict.addstringfield(r.id.tvdescription, new stringextractor<product>() {         @override         public string getstringvalue(product product, int position) {             return product.description;         }     });       dict.addstringfield(r.id.tvdate, new stringextractor<product>() {         @override         public string getstringvalue(product product, int position) {             return "" + product.date;         }     });       dict.addstringfield(r.id.tvqty, new stringextractor<product>() {         @override         public string getstringvalue(product product, int position) {             return "" + product.qty;         }     });       dict.adddynamicimagefield(r.id.ivimage,             new stringextractor<product>() {                 @override                 public string getstringvalue(product product, int position) {                     return product.image_url;                 }             }, new dynamicimageloader() {                 @override                 public void loadimage(string url, imageview imageview) {                                  imageloader.getinstance().displayimage(url, imageview);                     imageview.setpadding(0, 0, 0, 0);                     imageview.setadjustviewbounds(true);                 }             });      adapter = new fundapter<>(             listactivity.this, productlist, r.layout.layout_list, dict);       lvproduct.setadapter(adapter);     lvproduct.setonitemclicklistener(this); }  @override public void onitemclick(adapterview<?> parent, view view, int position, long id) {     product selectedproduct = productlist.get(position);     intent in = new intent(listactivity.this, detailactivity.class);     in.putextra("product", (serializable) selectedproduct);     startactivity(in);   }     //this share method public void sharemethod(view view1) {      intent sharingintent = new intent(android.content.intent.action_send);      sharingintent.settype("text/plain");     string sharebody = "share content body";     sharingintent.putextra(android.content.intent.extra_subject, "subject here");     sharingintent.putextra(android.content.intent.extra_text,sharebody);     startactivity(intent.createchooser(sharingintent, "share via"));  }    } 

when list item clicked, can form instance string variable, , fill in data product. in sharemethod, can add string sharestr , share. example,

public class listactivity..{        private string msharestr;            ...       <  *when list item clicked fill in*      msharestr = string.format("%s - %s %s : %s", name, description, date, qty);  >         public void sharemethod(view view1)       {           ...           sharingintent.putextra(intent.extra_text, msharestr);       }   }
