Once you get the information you need, you can put that information into your custom Listadaptar.
Class Myadapter extends Baseadapter {public class Holder {TextView tv_pakagename; TextView Tv_versioncode; TextView Tv_versionname; TextView Tv_appname;imageview Iv_logo;} @Overridepublic int GetCount () {return allprocess.size ();} @Overridepublic hashmap<string, object> getItem (int position) {return allprocess.get (position);} @Overridepublic long Getitemid (int position) {return position;} @Overridepublic view GetView (int position, view Convertview, ViewGroup parent) {Holder Holder; View v;if (Convertview = = null) {holder = new holder (); v = layoutinflater.from (Getapplicationcontext ()). Inflate (r.layout . List_menu, null); holder.tv_pakagename = (TextView) V.findviewbyid (r.id.tv_pakagename); Holder.tv_versioncode = ( TextView) V.findviewbyid (r.id.tv_versioncode); holder.tv_versionname = (TextView) V.findviewbyid (r.id.tv_ Versionname); Holder.iv_logo = (ImageView) V.findviewbyid (R.id.iv_logo); holder.tv_appname = (TextView) V.findviewbyid (r.id.tv_appname); V.settag (holder);} else {v = convertview;holdER = (Holder) V.gettag ();} Holder.tv_pakagename.setText ("Package Name:" + allprocess.get (position). Get ("PackageName"). toString ()); holder.tv_ Versioncode.settext ("Versioncode:" + allprocess.get (position). Get ("Versioncode"). toString ()); holder.tv_ Versionname.settext ("Versionname:" + allprocess.get (position). Get ("Versionname"). toString ()); holder.iv_ Logo.setimagedrawable ((drawable) allprocess.get (position). Get ("Appimage")); Holder.tv_appname.setText ("app Name:" + Allprocess.get (position).
