android - Dynamically change data of Custom PreferenceScreen -


i working on custom preferencescreen, have created custom screen settings page using preferenceactivity.

below preference screen.

enter image description here

issue:- need change badge of download data dynamically. followed question achieve layout. tried answer of question not working single answer.

is there other way find view inside preference?

settings.xml

<?xml version="1.0" encoding="utf-8"?> <preferencescreen xmlns:android="http://schemas.android.com/apk/res/android">  <preference android:title="@string/settings_user_profile" android:key="user_profile" android:summary="@string/settings_user_profile_desc" android:layout="@layout/setting_list"></preference> <preference android:title="@string/settings_download" android:key="download_data" android:summary="@string/settings_download_desc" android:layout="@layout/setting_list"></preference> </preferencescreen>

you can subclass preference, overriding onbinddialogview() - remember change xml <preference...> include package , class <com.example.app.badgedpreference...>:

@override protected void onbinddialogview(view v) {     super.onbinddialogview(v);     log.v( "onbinddialogview()", v.getclass().getsimplename() ); }

if badgedpreference has method handling change, can use bit more - within preferenceactivity:

preferencescreen myprefscreen = (preferencescreen)getpreferencescreen(); badgedpreference bp = (badgedpreference)myprefscreen.findpreference("download_data"); // custom method bp.setbadgevalue(12);

even more simply, can use standard preference, style summary field 'badge', can set value using included summary field:

preference pref = (preference)myprefscreen.findpreference("download_data"); pref.setsummary("12");

let me know if have questions.

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 ...
