android - Count item in xml -


i'm getting rss feed following:

        <item>         <caterory>sports</category>         <content:encoded>text 1......</content:encoded>         <title>title 1...</title>         </item>          <item>         <caterory>news</category>         <content:encoded>text 2......</content:encoded>         <title>title 2 ...</title>         </item>          <item>         <caterory>sports</category>         <content:encoded>text 3......</content:encoded>         <title>title 3 ...</title>         </item>           ......          <item>         <caterory>news</category>         <content:encoded>text x......</content:encoded>         <title>title x ...</title>         </item>

i create list ,and listitems should named category name.so,if user click on sports,he see sports new, etc. how easy done? searching net haven't found similar. now, have created list witch returns me list categories (ex. if have 25 articles, list 25 categories,sometime same,as 1.sports,2.news,3.sports,...etc)

int position=1; if (feed.getitem(position).getcategory()!=null) {   for(int pos=0;pos<feed.getitemcount();pos++){      //feed.getitemcount();      slidemenuitem item2=new slidemenuitem();     item2.id = myitemcategory;     item2.icon = getresources().getdrawable(r.drawable.favorite_full);     item2.label = feed.getitem(pos).getcategory();     slidemenu.addmenuitem(item2); }

sorry bad syntax,hope question understandable..:)

create set categories, eliminate duplicates. iterate set , add them 1 one menu.

http://docs.oracle.com/javase/6/docs/api/java/util/set.html

try this:

int position=1; if (feed.getitem(position).getcategory()!=null) {     set<string> categories = new hashset<string>();     for(int pos=0;pos<feed.getitemcount();pos++)         categories.add(feed.getitem(pos).getcategory();      for(string category : categories) {         slidemenuitem item2=new slidemenuitem();         item2.id = myitemcategory;         item2.icon = getresources().getdrawable(r.drawable.favorite_full);         item2.label = category;         slidemenu.addmenuitem(item2);     } }

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
