Answer 1

Use setOutlineProvider(null); on your appBar. Just be sure to check the SDK version. :)

Answer 2

Use app:elevation="0dp" in your AppBarLayout. Make sure you put Toolbar inside your AppBarLayout like this -

    <android.support.design.widget.AppBarLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:fitsSystemWindows="true"
        app:elevation="0dp"> 

        <android.support.v7.widget.Toolbar
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/firstOption"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    </android.support.design.widget.AppBarLayout>

and add this line to your activity - findViewById(R.id.appBarLayout).bringToFront();
This will bring the AppBar to front.

Answer 3

To remove elevation by using java code use the line below...

getSupportActionBar().setElevation(0);

Answer 4

Just remove this part of you layout hierarchy:

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

It's responsible for creating shadow. Toolbar itself doesn't cast any shadow.

Answer 5

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>

Answer 6

Get the appbarlayout in code:

var appbarLayout = findviewbyid<AppBarLayout>(resource.id.  );  

set the property

appbarLayout.StateListAnimator=null;
