android - ExpandableListView ParentPosition not getting -


hi have searched lot on topic still unable solve this.i pretty new in android.i not getting position of parent in expandablelistview,i getting value of childposition not groupposition. 

                catlist = (expandablelistview) findviewbyid(r.id.category_list);             final expandablelistadapter explistadapter = new expandablelistadapter(                     catergoryactivity.this, grouplist, expandablecategories);             catlist.setadapter(explistadapter);              catlist.setonchildclicklistener(new onchildclicklistener() {                  @override                 public boolean onchildclick(expandablelistview parent,                         view v, int groupposition, int childposition,                         long id) {                     intent nextact = new intent(catergoryactivity.this,                             mobileactivity.class);                      string childposition = explistadapter.getchild(groupposition, childposition);                      system.out.println("childposition------------------------>>>>>>>>>>>>"+childposition);                       nextact.putextra("locid", locid);                     nextact.putextra("childpos",                             childlist.get(childposition));                     nextact.putextra("grouppos", gruopposition);                      startactivity(nextact);                     return false;                 }             });

according api refference description of onchildclick, have position of parent group.

public abstract boolean onchildclick (expandablelistview parent, view v, int groupposition, int childposition, long id) added in api level 1

callback method invoked when child in expandable list has been clicked.

parameters

  • parent - expandablelistview click happened
  • v -the view within expandable list/listview clicked
  • groupposition - group position contains child clicked
  • childposition - child position within group
  • id - row id of child clicked

returns true if click handled

edited: there 2 positions in onchildclick need - parent , child. parent defines position of group, child defines position within group. adapter.getchild(grouppos, childpos) returns object related specified child item.

    catlist.setonchildclicklistener(new onchildclicklistener() {              @override             public boolean onchildclick(expandablelistview parent,                     view v, int groupposition, int childposition,                     long id) {                  system.out.println("childposition: " + childposition);                 system.out.println("groupposition: " + groupposition);                  // if need related data                 object itemdata = explistadapter.getchild(groupposition, childposition);               }         });

if need itemdata value, should implement getchild() method in adapter.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
