Answer 1

Just use after the super.onCreate(savedInstanceState);

if(getSupportActionBar() != null)
{
   getSupportActionBar().setElevation(0);
}

Answer 2

If your are not using Toolbar on the Layout and you have the default toolbar from AppCompactActivity this can help you

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

getSupportActionBar().setElevation(0);

At least it worked for me.

@DmitryO Hum my xml is like this, i don't have android.support.design.widget.AppBarLayout, just the toolbar widget,

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:fab="http://schemas.android.com/apk/res-auto"
    xmlns:materialdesign="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    android:theme="@style/AppThemeAccueil">

    <View xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="@dimen/statusBarHeight"
        android:background="@color/accueil_colorDark"
        android:elevation="@dimen/statusBarElevation"/>

    <android.support.v7.widget.Toolbar
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:popupTheme="@style/AppThemeAccueilToolbar"
        android:theme="@style/AppThemeAccueilToolbar"
        android:id="@+id/toolbarAccueil"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        materialdesign:elevation="0dp"
        android:elevation="0dp"
        android:outlineProvider="background"
        android:layout_marginTop="@dimen/appBarTopMargin" >

    </android.support.v7.widget.Toolbar>
</RelativeLayout>

Have I to had this ? (I think this will not change the result)

Answer 4

use app:elevation="0dp" instead of android:elevation

Answer 5

I had the same problem. Applying app:elevation="0dp" on android.support.design.widget.AppBarLayout solves the issue

Answer 6

Just put your AppBarLayout inside of a LinearLayout on a separated XML file, and then, include this XML to your main XML.
