android - Show Progress Indicator before fill listview using CursorLoader -


what better way show progress indicator while listview not filled data of database?

i found examples of how this, using assynctask, in case, using loader /cursorloader.

public class testactivity extends sherlockfragmentactivity implements     loadercallbacks<cursor> {  simplecursoradapter madapter; listview mlistview;  private static final string[] ui_binding_from = new string[] {         testdbadapter.key_name, testdbadapter.key_icon };  private static final int[] ui_binding_to = new int[] { r.id.text, r.id.icon };  @override public void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);      setcontentview(r.layout.activity_test);      mlistview = (listview) findviewbyid(r.id.listview);      madapter = new testadapter(getapplicationcontext(),             r.layout.list_item_test, null, ui_binding_from,             ui_binding_to, 0);      mlistview.setadapter(madapter);      getsupportloadermanager().initloader(0, null, this);  }  @override public loader<cursor> oncreateloader(int id, bundle args) {       uri uri = contentprovidertest.content_uri;      cursorloader cursorloader = new cursorloader(             this,              uri,             null,             null,             null,             null);      return cursorloader;  }  @override public void onloadfinished(loader<cursor> loader, cursor data) {     madapter.swapcursor(data); }  @override public void onloaderreset(loader<cursor> loader) {     madapter.swapcursor(null); } }

a possible solution, create new class extending listfragment , use setlistshown() method , not know if best way solve issue.

thanks

add small progressbar layout file, visibility set "gone". before create cursorloader, set visibility "visible". appear. in onloadfinished, set progressbar visibility "gone". disappear, , listview load.

i'd use small style progressbar. learn more this, see reference docs android.widget.progressbar.

btw, visibility controlled view.setvisibility.

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 ...
