android - Populate ListView and their detail views with from multiple sqlite tables -


currently i'm searching solution populate listview content 3 different sqlite tables. when tapped, each listview item (row) should show according detailed view (activity), based on 1 of 3 xml layouts.

any suggestions?

edit:

currently solved 1 type of object/sqlite table. fetching content sqlite table arraylist , pass via putextra detail activity, handles setting texts/content.

the matching of listview entry , starting according detail view solved arraylist index matches listview index.

i'm not sure, if proper solution. guess isn't...

public void onitemclick(adapterview<?> parent, view view, int position, long id) {     intent typeone_details_intent = new intent(this, typeonedetailactivity.class);    typeone_result = new typeoneresult();    typeone_result = typeoneresult_arr.get(position);     typeone_details_intent.putextra("result", typeoneresult);    startactivity(typeone_details_intent); }

how can solve add typetwodetails , better matching between listview , according detailview?

you can use custom adapter that can determine activity start, set custom row view, etc. 1 way, create row object interface, , check object type determine layout row , set things such onclick listener , activity launch.

quick example below:

public class customadapter extends baseadapter<listobjectinterface>{ ... listobjectinterface data[]; ....  public customadapter(context context, int layoutresourceid, listobjectinterface[] data) {     ... }  @override public view getview(int position, view convertview, viewgroup parent) {     view row = convertview;     ... /* things. such check if instance present, etc. */      listobjectinterface object = data[position];      if (object instanceof typea) {         row = inflater.inflate(layoutresourceida, parent, false);         ...         ... /* view objects , set button listener launch activity */     } else if (object instanceof typeb) {         row = inflater.inflate(layoutresourceidb, parent, false);         ...         ... /* view objects , set button listener launch activity b */     } ... /* etc */      ... /* more logic */      return row; } }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
