    android:elevation="0dp"
    android:theme="@style/SDK.Theme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:minHeight="?attr/actionBarSize"
        app:elevation="0dp"
        local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

Answer 1

You can remove the shadow programatically.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {            
    appBar.setElevation(0);
}

Where appBar is your AppBarLayout .

EDIT:

I've just noticed you use android:elevation="0dp" attribute. Use app:elevation="0dp" if you want to do it via xml.

如果您想尝试，这也有效。

appBarLayout.isEnabled = false
