Android: I cannot remove elevation / shadow on my toolbar

Question

Hi i would like to remove the elevation and shadow effect from my toolbar for API 21 and greater. Below is what i have tried

setSupportActionBar(mToolbar);         getSupportActionBar().setDisplayShowTitleEnabled(false);         getSupportActionBar().setElevation(0); 

My Toolbar in XML. I have tried to set elevation to 0dp

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:id="@+id/toolbar"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:background="@color/colorPrimary"     android:minHeight="?attr/actionBarSize"     android:elevation="0dp"     android:theme="@style/ToolbarStyle"     app:theme="@style/ToolbarStyle"     > 

And this is ToolbarStyle if it helps

<style name="ToolbarStyle" parent="ThemeOverlay.AppCompat.Dark">     <item name="colorControlNormal">@android:color/white</item> </style> 

Edit 1: Tried the following in styles v21. Still same result

<style name="ToolbarStyle" parent="ThemeOverlay.AppCompat.Dark">     <item name="colorControlNormal">@android:color/white</item>     <item name="android:elevation">0dp</item> </style> 

Edit 2: Where the toolbar is in my layout

android.support.v4.widget.DrawerLayout       xmlns:android="http://schemas.android.com/apk/res/android"         xmlns:app="http://schemas.android.com/apk/res-auto"         android:id="@+id/drawer_layout"         android:layout_width="match_parent"         android:layout_height="match_parent">          <android.support.design.widget.CoordinatorLayout             android:layout_width="match_parent"             android:layout_height="match_parent">              <android.support.design.widget.AppBarLayout                 android:id="@+id/appBarLayout"                 android:layout_width="match_parent"                 android:layout_height="wrap_content">                  <include layout="@layout/toolbar" /> 

Answer 1

You can do that with an easy step. Don't remove the android.support.design.widget.AppBarLayout from your layout, instead add the attribute app:elevation="0dp" to it. Your final layout will be:

<android.support.design.widget.AppBarLayout             android:id="@+id/appBarLayout"             android:layout_width="match_parent"             android:layout_height="wrap_content"             app:elevation="0dp">             ... </android.support.design.widget.AppBarLayout>
