        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@android:color/transparent"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"/>

Answer 2

try this

<android.support.v7.widget.Toolbar
 xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/toolbar"
 android:layout_width="match_parent"
 android:layout_height="?attr/actionBarSize"
 android:background="@drawable/background_toolbar" />

now create a background_toolbar.xml in res/drawble

<?xml version="1.0" encoding="utf-8"?>

 <shape
xmlns:android="http://schemas.android.com/apk/res/android">

<gradient
    android:angle="270"
    android:endColor="@android:color/transparent"
    android:startColor="#66000000"/>
</shape>

now set your toolbar
