i have preferencefragment activity shows following edittextpreference:

<edittextpreference             android:key="year"             android:title="@string/prefs_yearpicker"             android:summary="@string/prefs_yearpickersummary"             android:textallcaps="true"/> 

but when want change value, shows no cursor, , when press ok, crashes, returning following message:

preferences class code:

public class preferences extends actionbaractivity  {      final context context = getbasecontext();      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         // set layout         setcontentview(r.layout.preferences_layout);          // display fragment main content.         getfragmentmanager().begintransaction()                 .replace(r.id.preferences, new settingsfragment())                 .commit();          toolbar toolbar = (toolbar) findviewbyid(r.id.toolbar);         if (toolbar != null) {             setsupportactionbar(toolbar);         }          if (build.version.sdk_int >= build.version_codes.honeycomb) {             getsupportactionbar().setdisplayhomeasupenabled(true);         }     } }  public static class settingsfragment extends preferencefragment implements onsharedpreferencechangelistener {         @override         public void oncreate(bundle parambundle) {                  super.oncreate(parambundle);                 addpreferencesfromresource(r.xml.preferences);                  // shared preferences                 sharedpreferences prefs = getpreferencescreen().getsharedpreferences();                 // set on change listener                 prefs.registeronsharedpreferencechangelistener(this);                 // update summaries                 updateall(prefs);              } } 

i've tried without on change listener, same result.

void updateall(sharedpreferences prefs) {      // set summary     edittextpreference edittextpref = (edittextpreference) findpreference("year");     edittextpref.setsummary(prefs.getstring("year", ""));      // set summary of interval     listpreference listpref = (listpreference) findpreference("notificationsinterval");     string intervalvalue = prefs.getstring("notificationsinterval", "1800000");     string text = mstoh(integer.valueof(intervalvalue));     listpref.setsummary(text);  } 

what doing wrong? in advance!

final solution: see own answer.

just move updateall method onsharedpreferenceschanged().

@override public void onsharedpreferencechanged (sharedpreferences sharedpreferences, string key) {         updateall (sharedpreferences);  }
