              android:layout_width="match_parent"                 android:layout_height="?attr/actionbarsize"                 app:layout_collapsemode="pin"                 app:popuptheme="@style/apptheme.popupoverlay" />          </android.support.design.widget.collapsingtoolbarlayout>     </android.support.design.widget.appbarlayout> 

and code in activity's oncreate method:

setcontentview(r.layout.activity_agent_profile2);     toolbar toolbar = (toolbar) findviewbyid(r.id.toolbar);     setsupportactionbar(toolbar);     getsupportactionbar().setdisplayhomeasupenabled(true);     //getsupportactionbar().settitle("name");     agent = (agent) getintent().getserializableextra("agent");     collapsingtoolbarlayout collapsingtoolbar =             (collapsingtoolbarlayout) findviewbyid(r.id.agent_profile_toolbar);     collapsingtoolbar.settitle(agent.name); 

i fixed somehow. don't why work though. had give separate styles expandedtitle , collapsetitle different textsizes. if same textsizes work. here styles below,

<style name="expandedappbar" parent="@android:style/textappearance.medium">     <item name="android:textsize">20sp</item>     <item name="android:textstyle">bold</item>     <item name="android:ellipsize">end</item>     <item name="android:maxlines">1</item>     <item name="android:width">100dp</item> </style> <style name="collapseappbar" parent="@android:style/textappearance.medium">     <item name="android:textsize">18sp</item>     <item name="android:textstyle">bold</item> </style> 

and layout:

<android.support.design.widget.collapsingtoolbarlayout             android:id="@+id/agent_profile_toolbar"             android:layout_width="match_parent"             android:layout_height="match_parent"             android:fitssystemwindows="true"             app:contentscrim="?attr/colorprimary"             app:expandedtitlemarginbottom="87dp"             app:expandedtitlemarginstart="130dp"             app:expandedtitletextappearance="@style/expandedappbar"             app:collapsedtitletextappearance="@style/collapseappbar"             app:layout_scrollflags="scroll|exituntilcollapsed"> 

and screenshot prove works,
