anyone can point me problem, used:

android:layout_alignbottom="@+id/appbar"

"appbar" : appbarlayout

thanks

am wondering why need use multiple toolbar. instead if need place toolbar per shared image, place toolbar inside appbar layout. like:

 <android.support.design.widget.appbarlayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="@dimen/detail_backdrop_height" android:theme="@style/themeoverlay.appcompat.dark.actionbar" android:fitssystemwindows="true">  <android.support.design.widget.collapsingtoolbarlayout     android:id="@+id/collapsing_toolbar"     android:layout_width="match_parent"     android:layout_height="match_parent"     app:layout_scrollflags="scroll|exituntilcollapsed"     android:fitssystemwindows="true"     app:contentscrim="?attr/colorprimary"     app:expandedtitlemarginstart="48dp"     app:expandedtitlemarginend="84dp">      <imageview         android:id="@+id/backdrop"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:scaletype="centercrop"         android:fitssystemwindows="true"         app:layout_collapsemode="parallax" />      <android.support.v7.widget.toolbar         android:id="@+id/toolbar"         android:layout_width="match_parent"         android:layout_height="?attr/actionbarsize"         android:background="@drawable/gallery_toolbar_shape"         app:popuptheme="@style/themeoverlay.appcompat.light"         app:layout_collapsemode="pin" />     <progressbar         android:id="@+id/gallery_progressbar"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_gravity="top"         android:layout_margintop="-7.5dp"         style="?android:attr/progressbarstylehorizontal"/>   </android.support.design.widget.collapsingtoolbarlayout>     <android.support.v7.widget.toolbar    android:id="@+id/personaltoolbar"    android:layout_width="match_parent"    android:layout_height="?attr/actionbarsize"    android:layout_alignbottom="@+id/appbar"    android:layout_alignparentbottom="true"    android:background="@color/personal_tb"    app:popuptheme="@style/themeoverlay.appcompat.light"    />      </android.support.design.widget.appbarlayout>
