android - ListView with single choice to show unique selection -


i want have listview single choice. use checkedtextview , when user clicks on 1 row, update checkedtextview. if clicks on row, old selection retrieve "normal" ui , new selection takes new ui.

it works fine on nexus 7 (4.2.2) on galaxy s ii (4.0.4), have case have 2 rows selected , must click twice have right behavior.

i precise, have set property :

setchoicemode(listview.choice_mode_single);

here layout : 

<?xml version="1.0" encoding="utf-8"?>     <checkedtextview xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:custom="http://schemas.android.com/apk/res/com.ecab"     android:id="@+id/option"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:layout_margin="10dp"     android:background="@drawable/ban_vhcl_list_off"     android:gravity="center_vertical"     android:paddingleft="10dp"     android:paddingright="10dp"     android:text="@string/fake" />

here adapter

private class optionsadapter extends arrayadapter<string> implements onitemclicklistener {     private final list<string> options;     public optionsadapter(list<string> poptions) {         super(vehiculeactivity.this, r.layout.vehicule_list_item);         options = poptions;     }      @override     public int getcount() {         return options.size();     }      @override     public string getitem(int position) {         return options.get(position);     }      @override     public view getview(int position, view convertview, viewgroup parent) {         if (convertview == null)             convertview = layoutinflater.from(vehiculeactivity.this).inflate(r.layout.vehicule_list_item, null);         checkedtextview option = (checkedtextview) convertview.findviewbyid(r.id.option);         option.settext(options.get(position));         if (!option.ischecked()) {             log.d(constants.d_tag, "is not checked");             option.setcompounddrawableswithintrinsicbounds(0, 0, 0, 0);             option.setbackgroundresource(r.drawable.ban_vhcl_list_off);         } else {             log.d(constants.d_tag, "is checked");             option.setcompounddrawableswithintrinsicbounds(0, 0, r.drawable.check_box, 0);             option.setbackgroundresource(r.drawable.ban_vhcl_list_on);         }         return convertview;     }      @override     public void onitemclick(adapterview<?> parent, view view, int position, long id) {         checkedtextview option = (checkedtextview) view.findviewbyid(r.id.option);         option.setchecked(true);         notifydatasetchanged();     } }

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
