public class mainactivity extends listactivity {   private customadapter customadapter;  list<string> contacts = new arraylist<string>();  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);        listview lv = (listview) findviewbyid(android.r.id.list);     customadapter = new customadapter(this);     lv.setadapter(customadapter);  }  @override protected void onresume() {     super.onresume();     log.d("tag","onresume");     loadapps(); }      public void loadapps(){      //cursor cursor = getcontentresolver().query(contactscontract.commondatakinds.phone.content_uri, null, null, null, null);     cursor cursor;     contentresolver contentresolver = getcontentresolver();     cursor = contentresolver.query(contactscontract.contacts.content_uri,null,             contactscontract.contacts.has_phone_number + " = 1",             null,             "upper(" + contactscontract.contacts.display_name + ") asc");          customadapter.clear();     if (cursor.getcount() > 0) {         cursor.movetofirst();          {             string name = cursor.getstring(cursor.getcolumnindex(contactscontract.contacts.display_name));              contacts.add(name);          } while (cursor.movetonext());     }     cursor.close();      (string names : contacts) {          appinfoitem appinfoitem = new appinfoitem();          appinfoitem.name = names;          customadapter.add(appinfoitem);      } }    @override protected void onlistitemclick(listview l, view v, int position, long id) {     super.onlistitemclick(l, v, position, id);      intent intent = new intent(intent.action_view,             uri.parse("content://contacts/people/"));      if (intent != null) {         startactivity(intent);     }  } } 

customarrayadapter.class

public class customadapter extends arrayadapter<string> {  layoutinflater layoutinflater;   public customadapter(context context) {      super(context, 0);      layoutinflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);   }   @override public view getview(int position, view convertview, viewgroup parent) {       // create cell , populate data of array     if (convertview == null)         convertview = layoutinflater.inflate(android.r.layout.simple_list_item_1, parent, false);      appinfoitem item = (appinfoitem) getitem(position);     //string name = names[position];      textview textview = (textview) convertview.findviewbyid(android.r.id.text1);     textview.settext(item.name);          return convertview; }   } 

appinfoitem.class

public class appinfoitem {  string name; string id;   } 

i think need use intent action_view action , intent data set contact's uri of form

content://contacts/people/1 

as shown in first example here http://developer.android.com/reference/android/content/intent.html#intentstructure
