sharedpreferences - Android no set default values -

i followed the instructions setting default preference values step step not work.

1º set default values:

<preferencecategory android:title="@string/settings_game" >     <listpreference         android:defaultvalue="1.5"         android:entries="@array/intervale_count"         android:entryvalues="@array/intervale_count_values"         android:key="interval"         android:title="@string/interval" />     <listpreference         android:defaultvalue="@string/mode_normal"         android:entries="@array/mode_game"         android:entryvalues="@array/mode_game_values"         android:key="mode"         android:title="@string/mode" /> </preferencecategory> <preferencecategory android:title="@string/settings_sound" >     <listpreference         android:defaultvalue="@string/stone"         android:entries="@array/time_sounds"         android:entryvalues="@array/time_sounds_values"         android:key="time_sounds"         android:title="@string/sounds_stones" />     <listpreference         android:defaultvalue="@string/vuvucela"         android:entries="@array/gong_sounds"         android:entryvalues="@array/gong_sounds_values"         android:key="gong_sounds"         android:title="@string/sounds_gong" /> </preferencecategory> 

2º preferences in mainactivity:

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     preferencemanager.setdefaultvalues(this, r.xml.preferences, false);     sp = preferencemanager.getdefaultsharedpreferences(getbasecontext()); }  

but when open preference view no preferences selected, strings of declare in android:defaultvalue same 1 of options ihave in array of data in android:entries.

note: try change true boolean in

preferencemanager.setdefaultvalues(this, r.xml.preferences, false);  

but still not work.

i've tried uninstall , delete data of app still not work.

edit: array values

<string-array name="intervale_count">     <item>1</item>     <item>1.3</item>     <item>1.5</item>     <item>1.7</item>     <item>2</item> </string-array> <string-array name="intervale_count_values">     <item>1000</item>     <item>1300</item>     <item>1500</item>     <item>1700</item>     <item>2000</item> </string-array> <string-array name="mode_game">     <item>@string/mode_normal</item>     <item>@string/mode_extension</item>     <item>@string/mode_infinite</item> </string-array> <string-array name="mode_game_values">     <item>100</item>     <item>50</item>     <item>1000</item> </string-array> <string-array name="time_sounds">     <item>@string/alan</item>     <item>@string/cash_reg</item>     <item>@string/censure</item>     <item>@string/crow</item>     <item>@string/doh</item>     <item>@string/fb_noti</item>     <item>@string/achievement</item>     <item>@string/metal_gear</item>     <item>@string/duck</item>     <item>@string/pan</item>     <item>@string/drum</item>     <item>@string/stone</item>  </string-array>    <string-array name="time_sounds_values">     <item>2131099648</item> <!-- alan -->     <item>2131099649</item> <!-- registradora -->     <item>2131099650</item> <!-- censura -->     <item>2131099651</item> <!-- cuervo -->     <item>2131099652</item> <!-- doh -->     <item>2131099653</item> <!-- fb -->     <item>2131099655</item> <!-- logro -->     <item>2131099656</item> <!--metal gear  -->     <item>2131099657</item> <!-- pato -->     <item>2131099658</item><!-- sarten -->     <item>2131099660</item> <!-- tambor -->     <item>2131099659</item><!-- stone --> </string-array> <string-array name="gong_sounds">     <item>@string/gong</item>     <item>@string/vuvucela</item> </string-array> <string-array name="gong_sounds_values">     <item>2131099654</item> <!--  gong -->     <item>2131099661</item> <!-- vuvucela --> </string-array> 

the defaultvalue attribute listpreference needs value, not entry text. in other words, should element in array pass android:entryvalues, not element in array pass android:entries.

for example, gong sounds preference should use android:defaultvalue="2131099661" instead of android:defaultvalue="@string/vuvucela"
