Android Toolbar MenuItem LowerCase -

i want make menuitem title lower case in toolbar.
menu.xml

 <item     android:id="@+id/action_done"     app:showasaction="always"     android:title="done"/> 

on toolbar shows "done" want show "done". tried solve case using textallcaps="false" not find proper parent class apply style "actionmenutextappearance".

what right solution, need guidance here, thank you.

try use this:

 <item     android:id="@+id/action_done"     app:showasaction="always"     android:title="@string/action_done"/> 

instead of this

 <item     android:id="@+id/action_done"     app:showasaction="always"     android:title="done"/> 

and in strings.xml

<resources>      <string name="action_done">done</string> </resources>
