Nested Preference Screen closes on Screenorientation change in Android -


i stumbled upon problem.

i working nested preferencescreen this:

<preferencescreen xmlns:android="http://schemas.android.com/apk/res/android" >  <preferencescreen     android:key="pref_name"     android:title="@string/pref_title" >  </preferencescreen>

when screen has focus on nested preference screen , change screenorientation, nested preferencescreen closes.

i have tried including:

android:configchanges="orientation|keyboardhidden"

in androidmanifest.xml, didn't work.

does have solution this?

edit possible solution:

i did find solution. thought line:

android:configchanges="keyboardhidden|orientation|screensize"

got it. in order prevent nested screen closing on rotation, need make sure parent screen given key value. thats it. eg:

<preferencescreen xmlns:android="http://schemas.android.com/apk/res/android"      android:key="useless_key">      <preferencescreen         android:key="pref_name"         android:title="@string/pref_title" >     </preferencescreen> </preferencescreen>

side note, though overriding onconfigchanges solved issue, should never so. changes how activity behaves. rotation 1 of many reasons why config change happens. if activity can't handle rotation properly, it'll fail on handling other conditions. check out insightful post more.

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 ...
