android - First and last EditText in ListView is showing the same value -


when showing in view, value enter last edittext being shown in both first , last edittext boxes if scroll past first edittext box. when saving value database, saving last edittext value expected however.

what causing behaviour? here complete code:

at end of getview(), should change text in membamount; otherwise, if reuses convertview, keeps previous text.

viewholder.membamount.settext(list.get(position).getamount());

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 ...
