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? -
