How to add bottom shadow to tab layout or Toolbar in android

Hi i need add shadow under my tab layout (like in skype).

shadow_skype

My activity xml:

    <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.Toolbar xmlns:local="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/splashGreenTop"
        local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_below="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:elevation="0dp"
        android:minHeight="?attr/actionBarSize" />
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_below="@+id/tab_layout"
        android:id="@+id/tabContainer"
        android:layout_height="match_parent" />
</RelativeLayout>

Just add elevation to your Tablayout (0dp - 25dp). Read the material design guidelines for more information about elevation.

android:elevation="10dp"

EDIT:
add it to both your tablayout and toolbar

<android.support.v7.widget.Toolbar xmlns:local="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:background="@color/splashGreenTop"
    local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    local:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    android:elevation="10dp" />
<android.support.design.widget.TabLayout
    android:id="@+id/tab_layout"
    android:layout_below="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize" 
    android:elevation="10dp"/>

This is a Great option to add shadow below Toolbar

Add a view below the tablayout of your desired layout

 <RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.Toolbar xmlns:local="http://schemas.android.com/apk/res-auto"
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="?attr/actionBarSize"
        android:background="@color/splashGreenTop"
        local:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        local:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_below="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/colorPrimary"
        android:elevation="0dp"
        android:minHeight="?attr/actionBarSize" />

       <View
        android:layout_width="match_parent"
        android:layout_height="5dp"
        android:layout_below="@+id/tab_layout"
        android:background="@drawable/toolbar_dropshadow" />
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_below="@+id/tab_layout"
        android:id="@+id/tabContainer"
        android:layout_height="match_parent" />
</RelativeLayout>

then create a xml in drawable like this
@drawable/toolbar_dropshadow:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<gradient
    android:startColor="@android:color/transparent"
    android:endColor="#88333333"
    android:angle="90"/>
</shape>

Change the startcolor and endcolor as u want to apply
